Now many factory buildings are all steel structure, generally this kind of factory buildings using LED high bay lights more, because the irradiation distance of LED high bay lights are far, to achieve reasonable lighting conditions, LED high bay lights are the most appropriate choice! There are also many factory buildings using ordinary energy-saving lights, disadvantage of these energy-saving lights "save electricity but not money" in the use. Some enterprises mark the light power standard highly, but can not up to; the brightness of the lights are good in the beginning of the use, but soon grew dark, and life is very short.

Energy saving and emission reduction is a basic requirement for domesticindustrial lightingnow, is also in line with the development of enterprise interests. To achieve energy-saving and emission reduction must be given more attention on the type of the factory lighting, so as to ensure good lighting conditions, can effectively improve the work efficiency of staff in enterprise. So enterpris must pay more attention to choosing industrial lighting.

In the era of the rise of LED lighting, LED high bay lights has entered various factories, each workshops in the actual application. There are still some 

First, glare.

Second, impression of space. The light emitted by current LED high bay lights  basicly vertical downward, most of the LED light fixtures are with aluminum cover, due to the brightness of LED chip surface is high, so the top of the factory building is very dark, so that creates a sharp contrast between the light below and the light above, give a person a heavy sense of oppression, resulting in lack of impression of space.

Third, because now chips of LED high bay lights used by many factories are using the way of single tile, so there will be spot for each single light in industrial lighting, a large integrated chip will generate a lot of spot, making the object illuminated by the lights appear more obvious ghost.

Fourth, the problem of reflection, because the LED is mainly direct light, together with the plant worktop mostly metal materials, a lot of light will be directly into the human eyes, greatly reducing the work comfort of the workers, so some people will feel uncomfortable when factories using LED lighting. In fact, the color rendering index of LED high bay light is obvious, but also far ahead in energy efficiency, and now the main problem is concentrated in the comfortable sensation of the work environment, which is the the aspects of improvement that LED high bay light manufacturers need to strengthen.

As mentioned above, LED high bay lights used by factory is also a lack of basic research in the application process, the lighting requirements of traditional high bay lights achieve through the reflector, and LED products achieve lightin through the the lens and reflector in the middle. However, due to the study of the lens is not very mature, and more are moved traditional high bay lights to imitate, which makes the problem of glaring and unilluminating.

Incandescent lamps in memory, perhaps can buy no longer in the future. According to the "phase-out incandescent road map in China" issued by 2010 National Development and Reform Commission and other five ministries. From  October 1 this year, China will ban or import the sale of general lighting incandescent lamp of 15-watt and above. Energy-saving lights, LED light fixtures have become the mainstream lighting products on the market, the lighting market has ushered in another development opportunities. 

General lighting has the features of huge market space, widely distributed, the low geographical concentration, taking the challenges to the market and industry regulation.

The phase-out plan of incandescent lamps will be coming.

In 2011, the Development and Reform Commission announced "China phase out incandescent road map, divided phase out incandescent road map; into five stages: November 1, 2011 to September 30, 2012 for the transition period, from October 1,2012 ban on the import and sale of general lighting incandescent with 100 watts and above, from October 1, 2014, ban on the import and sale of general lighting incandescent with 60 watts and above, October 1, 2015 to September 30, 2016 are medium-term evaluation period, from October 1, 2016, ban on the import and sale of ordinary incandescent lighting with 15-watt and above, or adjusted as the results of medium-term evaluation. According to the "road map", the phase-out plan of incandescent lamps will be coming.

In addition to this road map, Beijing has also introduced related programs of phase out incandescent lamps, compared to more stringent. In 2012, the Beijing Development and Reform Commission issued "Beijing eliminated the general lighting incandescent lamps action plan (2011-2015)", plans to stop imports and sales of incandescent lamps with 15 watts and above, before 2015. In the end of 2015, hotels, restaurants, shopping malls, commercial office, industrial enterprises and other production units to fully stop the use of incandescent lamps.

Currently on the market in Beijing, has been difficult to see the incandescent lamps. Well-known home retailers IKEA announced in 2015, the global IKEA stores will only sell LED light fixtures, no longer sell incandescent lamps. Some business men said: There are few manufacturers to sell incandescent lamps, incandescent lamps with high power consumption, easy to bad, there are some light fixtures with more lamps may need to achieve certain lighting by using incandescent lamps, but the family commonly used the lamps and lanterns.

LED home lighting market is optimistic.

Incandescent lights farewell to the market, what kind of lighting products will become the mainstay of the market? At present, in the domestic market, the main types of general lighting are incandescent lamps, halogen lamps, high pressure gas discharge lamps, fluorescent lamps and LED lights, of which, fluorescent lamps has the largest market share. However, the current market believes that led light fixtures will become the main product of home lighting in future.

LED solar street lights, as the name suggests, is the LED fixture use the sun light as main source energy, save up the electricity converted by the sun during the day, and output the current at night, making the lights lighting. LED solar lights are green light fixtures which have the advantages of low installation cost, low maintenance costs, security, energy saving, intelligent control, stable and durable, etc., so favored by more and more engineering.

At present, the common types of LED solar lights are street lights, garden lights and lawn lights. Although the installation of LED solar lights has no geographical restrictions, but because of its energy source has a special nature, therefore, we need to pay attention to the following problems when installing lights:

LED solar lights

As far as possible to choose a well-lit area. Due to the different latitude, height, climate and other factors, the effects of LED solar lights installation  in different places are not the same. Such as, Tibet is the most abundant area of ​​sunshine in China, therefore, the installation of solar lights in Tibet can make full use of local resources. On the contrary, solar lights can difficult to fully play its usefulness in the areas with more rainy season.

Avoid the occurrence of occlusion at the top of the lights. In the installation, must avoid the occurrence of occlusion at the top of the lights to ensure that the solar cell module to absorb and reserve energy, otherwise, will affect the use of lights at night.

Pay attention to the angle of the module of solar lights. When installating, we must ensure that the module of solar lights should be tilted fixed installation, the angle between the panel and the horizontal plane is about equal to increase 5 ~ 15 ° on the base of the latitude of installation location, to ensure that the absorption of light energy for solar panels.

However, whether a project should install LED solar lights, need related assessment by engineering, at the same time, to develop lighting programs according to the local conditions, fully integrate the local resources, so that the lamps can maximize its effectiveness.

Badminton, table tennis and other types of balls are multi-directional, multi-angle flighting in the air, players playing the balls are multi-angle, making multi-phase movement at different speeds, it is always a process of tracking, capturing and focused imaging between the human eyes and the badminton and table tennis. The process of playing the ball is the process of tracking the ball flight path and aerial positioning.

For indoor badminton, table tennis, basketball, volleyball, tennis and other sports stadium lights. There are a number of lighting effect indicators should be reached. However, from the practical point of view in practical exercise, for the civil fitness indoor stadium with leisure and fitness, lighting quality level should not be adopt a unitary standard of rigid indicators. According to the investment situation, playing level of players etc. many other technical and economic factors, determined by the investment operators in a reasonable range.

Meeting the use is practical, practical is good. A lot of stadium lighting cases of indoor badminton, table tennis, basketball, volleyball, tennis show that: indoor lighting of civil stadium with fitness function which grasping the following five aspects of lighting quality, lighting effects can reach a certain level, will be able to meet playing exercise requirements.

stadium lights

Indoor stadium lights should be no glare.

Once there is glare in badminton, table tennis, basketball, volleyball and other indoor stadium lighting, multiple locations and different angles of stadium will produce glare. Players can only see a strong stimulation of light, but can not see the flying ball, produced dazzling or discomfort visual effects in the visual system.

Indoor stadium lights should be no stroboscopic effect.

At present, in badminton, table tennis, basketball, volleyball and other indoor stadium lighting, the stadium lights widely used are metal halide lights, bar lights, ordinary high-power energy-saving lights and so on. They have varying degrees of stroboscopic and stroboscopic effect.

Indoor stadium lights should be high color performance.

Lights only are bright, it is also important that light should with color. Light is just the founder of the colorful world. The principle of visual physiology reveals that light energy acts on the human visual organs, not only in the visual perception system to produce bright sense, but also to produce a sense of color. In the bright visual state, the bright sense corresponds to the intensity of the light energy, and the color sense corresponds to the wavelength of the light energy.

Indoor stadium lights should be the sun color.

Sunlight radiated to the ground are mainly three parts of UV-light, visible light, infrared light. UV-light and infrared light are invisible to the human eye, the light that the human eye can see is visible spectrum.

Indoor stadium lights should be energy saving.

The economic and technical objectives that indoor stadium lights in badminton, table tennis, basketball, volleyball, tennis and other stadium lighting should pursued is to achieve the most bright, clear, true and comfortable lighting quality in the most reasonable investment in lighting fixtures and minimum lighting operating costs.

In current, there are many lights can be used for indoor stadium lighting, such as J-series LED stadium lights in Hangzhou ZGSM, we have great advantages in price, technical performance, the number of lights used in stadium, lighting effects and so on. We are leading in the field of lighting.

In recent years, LED lighting industry is becoming mature in Europe, the United States, Japan and other places, China's domestic market competition tends to white-hot, and turn into the era of fighting the scale, fighting the price. The establishment of the ASEAN Community and the promotion of the strategy of "The Belt and Road Initiative", leaving LED lights manufacturers increasing the attention rate in Southeast Asia and Egypt, Israel, Saudi Arabia and Turkey etc. "The Belt and Road Initiative" national market year by year.

Turkey is another booming emerging economy after "BRIC countries", China, Russia, India, Brazil and South Africa. It enjoys the reputation of "Next Eleven" in the international community and has become the member of "Economic Security Council" G20. According to data from 2016, Turkey's economy grew by a percent of 4.8, making it become one of the top five fastest-growing economies in the world.

With the construction of Silk Road economic belt and 21st century maritime Silk Road, China and Turkey once again in close contact, the two sides have a wider range of cooperation in the areas of frastructure construction, economic and trade. According to the latest data released by the Turkish Statistical Bureau, the first half of 2016, China-Turkey trade amounted to 13.716 billion US dollars, up to 0.73% year on year. Among them, Turkey imports 12.728 billion US dollars from China, up to 2.48% year on year, exports 989 million US dollars to China, low to 17.44% year on year. Data shows that China is the second largest trading partner for Turkey, the proportion of China and Turkey trade volume accounted for total foreign trade of Turkey rose 0.1%, China and Turkey trade deficit expanded 4.61% year on year.

On the LED lights industry, from the data of General Administration of Customs shows that in the first half of 2015, China's total exports of LED lighting
products about 50 billion US dollars, grow 16% compared with the first half of 2014 year on year, of which more than 45 million US dollars exported to Turkey. First half of 2016, China's top ten key areas of LED products exports amounted to 20.221 billion US dollars, of which the amount of exports of Turkey over 129 million, jumped to 28th.

With the development of the local economy, in recent years, productivity of the Turkish lighting industry has been greatly improved, but still the lack of LED lights manufacturers, LED technology is low, high production costs, unable to meet the local demand, mainly rely on imports, then brings business opportunities to overseas suppliers.

Due to the changment of government investment in outdoor lighting, the penetration rate of LED lighting will show an exponential rise in the next few years, replacing the traditional halogen lamps and incandescent lamps in rural areas. The data shows that the market size of current lighting and lighting market in Turkey is about 350 million US dollars. Research and Markets expects the Turkish LED market will grow at a compound annual growth rate of 15.6% from 2016 to 2022. By the the year of 2022, the market size will reach 344 million US dollars. In the Turkish market, LED signage and billboards are expected to have the highest growth rate.

In addition, because of its special geographical location, national manufacturers regard Turkey as a strategic market. Turkey across the Eurasian
continent, north of the Black Sea, south of the Mediterranean, west of the Aegean Sea, so the products exported to Turkey, can be exported to the Middle East, Europe and even Africa and other markets. Turkey has a customs union with the European Union, the EU is Turkey's traditional market; the transport only takes 6-11 days from Turkey to major European countries. Istanbul and Turkey share the European information in a large extent. By understanding the Turkish market, you can understand the latest European market letter, making enterprises seize the opportunity in the fierce competition.

At present, there are many low-cost and low-quality LED lights in the market, many people may be wondering how do those cheap LED lights make. The characteristic of China LED lights market is the price. As for the technical parameters, life, warranty period etc. are ignored by many customers.

Buyers will choose cheap LED lights, but can cheap LED lights manufacturers make quality products?

How did those cheap LED lights make? Costs of LED lighting are three aspects- lamp beads, shell, drive power. In order to make the lowest price ,they will do effort only in these three areas.

Lamp beads - 1W lamp beads in Zhongshan Guzhen can sell 2 cents, why do they dare to sell two cents? The gold wire inside of lamp beads instead by copper wire, other raw materials instead by low-quality material, which consumers can not perceive, and marked 1W, but may be only 0.5W with the device detection, and consumers are generally not to test.

Shell - with some corner aluminum or plastic, cost in 1 to 3 yuan.

Drive power - the poor driver on the market today have been sold more than one yuan, and even lower, so you can not know how many manufacturers who making LED lights collapsed, and those who irresponsible but to do poor-driven business, earn many money.

In this way, the cost of LED light is just more than 10 yuan.

Businessmen have to make money. And then count the management costs, inventory costs, development costs, etc., and about 5% business extraction, the price of 3W LED lights can not be less than 10 yuan! 

So, how to pick a good LED fixtures? The following points are for reference:

LED brightness is different, the price is different. LED lamps for LED fixtures should be suitable for laser class Ⅰ standard.

LED with strong anti-static ability has long life, and thus with a high prices.

LEDs with a consistent wavelength, have a same color, such as the requirements of the same color, the price is high.

Emitting angle. The different use of LED with the different light angle. The specific angle will has a high price.

Life, the key of different quality is life, life is determined by the light fades. Small Light decay, long life, high prices.

In the background of high-speed development and energy-saving emission reduction of the LED lighting, more and more cities replace their street lights by LED lighting products, it is expected that the number of street lights will reach 350 million in 2025. Recently, which cities have opened the installation project of LED street lights?

Montreal, Canada, 132,000 street lights will be transformed into LED street lights.

It is reported that the city government of Montreal, Canada, will make a decision on replacing its 132,000 street lights with the LED light source products.

The city of Montreal has plans to replace its incandescent bulbs with more cheaper and more energy-efficient LED lighting products(mainly 4000K). However, considering that the high color temperature may bring health problems, the city people opposed to it. Many people like 3000K light source products in Toronto and Chicago.

Montreal Mayor said that despite the city government has not yet made a decision, but now the voice of giving up the 4000K is high. It is reported that once it is determined which color temperature to use, the city of Montreal may carry out the large-scale project bidding.

Singapore plans to replace the street lights of the country with LED street lights before 2022.

Singapore Land Transport Authority announced that they plan to replace the island street lights with more energy-efficient LED street lights before 2022, and adopt the new remote monitoring system, switch street lights according to weather conditions.

Singapore authorities have launched two pilot projects in the past, in some areas to test high power and general power LED street lights. They began to change the street lights into LED street lights in some areas from 2013, has been installed LED street lights for about 4000 street lights.

The Singapore Government Street lights Replacement Program will be carried out in three phases: 

Stage one will cover 500 roads which are low-traffic and located in residential area, plan to completed by 2018. 

The second stage, which is concentrated in the central region, it is expected to be completed by 2019. 

The third stage, replacing the rest of the street lights project and it is expected to be completed before 2022.

The Uzbekistan government wants to invest 84.8 billion som for the urban street lights transformation.

According to the Uzbek Ministry of Finance news, in order to reduce energy consumption, introduce advanced energy-saving technologies, optimize the lighting system, the Ukrainian government plans appropriate funds 84.8 billion som (about 28.3 million US dollars according to the official exchange rate) in 2017-2019 for upgrading 28 city including the Tashkent city of the street lighting system including 28 city street lighting system.

The project involves replacing 8,283 luminaire and optimizing 2779.2 km of lines, plans to replace the existing high-energy-consuming luminaires with modern energy-efficient lighting that used the light-emitting diode technology by 2020 .

Taiwan Jia City plan to install LED street lights.

Goverment of Chiayi City, Taiwan said that, the city replaced a total of 30000 mercury lights, and installed on the new LED street lights, it is expected to complete 13000 lights in the first stage before the Lunar New Year, the 17,000 lights of the second stage is expected to contract with the contractor in the near future, construction after the Spring Festival.

Director of Works, Mr Lee Kin-yin, said that the project costs of the first stage paid from the central grant of $ 130 million. The second project cost is $ 170 million, purchasing 17,000 LED street lights and can save about 25 million yuan using LED street lights each year.

Recently, the haze once again sweeping across the country, as the lighting enterprise, we can not change the environment, but can do small thing, so that people not can see only the lights but also the road when going out, Which requires increasing penetration of the LED street lights.

Color temperature selection of LED street lights  

LED packaging process currently used through applying the phosphor with different excitation wavelengths, adjusting the amount or the proportion of phosphor to obtained white LED light source with different color temperature. Different light sources emit different color temperature, low color temperature light source is characterized by energy distribution, the red radiation is relatively more, usually called "warm light; After color temperature increasing, the proportion of blue radiation will be ncreased in the energy distribution,  commonly referred to as "cold light." For white LED light, there is a relative more proportion in yellow for the low color temperature, however, there is a relative more proportion in blue for the high color temperature. From the human visual point of view, low color temperature gives a warm, stable feeling, and high color temperature gives a deserted, refreshing feeling.

The color temperature of some common light sources

In general, LED light sources can be divided into warm white, neutral white and cold white, three categories. The color temperature of traditional street lights are generally warm white light that about 2300K, the human eye vision will obviously feel yellow. LED can be produced different color temperature of the light source through the packaging process, give the road lighting a lot of different options.

The relationship between color temperature and light efficiency

It is noteworthy that, for the color temperature selection in the early group of LED lights, almost all manufacturers have chosen 6000K, or even more than 6000K, this is why? It turned out that under the technical conditions that the early phosphor, cool white LED light source with a higher light efficiency. Compared to color temperature, people pay more attention to the physical properties of light efficiency. The most important means to improve light efficiency is to improve the excitation efficiency of the phosphor, excitation efficiency of YAG yellow powder is much higher than the orange powder.

Higher color temperature can get higher light efficiency, light efficiency of 5500-6500K color temperature can enhance 48.7% than the warm white light source which less than 3500K. LED is energy-saving, entirely because the LED has a higher light efficiency than other light sources, put aside the energy efficiency and talking the energy-saving is meaningless. 

High light efficiency not only bring higher energy efficiency, but also reduce the cost of lights, making the products more competitive. So most of the LED street light manufacturers select to producing the products with 6000K color temperature in order to pursue high energy-saving rate.

In recent years, LED technology is still high-speed developing, the light efficiency of chip continuously improve, energy efficiency rate has also been guaranteed. The contradiction between light efficiency and color temperature is no longer the main contradiction in the application process, and whether the color temperature and environmental conditions are coordinated is the focus should be paid attention. Synthesize technical conditions, climatic conditions, the current environmental conditions and the human eye senses, we propose, color temperature of LED street lights should choose the range of 3000 ~ 5700K. This color temperature will not have a large impact on light efficiency, but also to ensure the penetration of haze, and adapt to our people's visual senses.

LED flood light is a point source that can illuminate uniformly in all directions, and its irradiation range can be adjusted arbitrary. LED flood lights are the most widely used light source in renderings, and standard LED flood lights are used to illuminate the entire scene. Multiple LED flood lights can be used in the scene to produce better results. LED flood lights can be placed anywhere in the scene. For example, it can be placed outside the scope of the camera, or inside the object. LED flood lights can project dark and light, and then mix on the model. Because of the wide range of LED flood lights, LED flood lights are predictable and have many ancillary uses, such as placing the LED flood lights near a surface of the object, to produce a bright light.

LED flood lights

LED flood lights are mainly used for building decorative lighting, as well as commercial space lighting, decorative components heavier, its appearance is also round and square, because generally have to consider the heat radiation, so there are some differences between LED flood lights and traditional spotlights in shape.

Matters need attention to when installation:

Installation should be fixed firmly, so as not to fall off from the height.

Wire connection should use waterproof connectors, so as to avoid leakage in case of water.

After adjusting angle, to fasten the nut at both ends of the light holder, so as not to loose.

Recently, which cities have opened the installation project of LED street lights?

Montreal, Canada, 132,000 street lights will be transformed into LED street lights.

It is reported that the city government of Montreal, Canada, will make a decision on replacing its 132,000 street lights with the LED light source products.

The city of Montreal has plans to replace its incandescent bulbs with more cheaper and more energy-efficient LED lighting products(mainly 4000K). However, considering that the high color temperature may bring health problems, the city people opposed to it. Many people like 3000K light source products in Toronto and Chicago.

Montreal Mayor said that despite the city government has not yet made a decision, but now the voice of giving up the 4000K is high. It is reported that once it is determined which color temperature to use, the city of Montreal may carry out the large-scale project bidding.

Its features of low energy consumption, environmental protection, no flash, making it has a much wider range of application, then, in order to ensure its service life, the daily maintenance of LED flood lights is very important.

Regularly eliminate the dust and dirt on the light housing, improve lighting efficiency and heat dissipation. Cleaning method can use water or wiping with a damp cloth according to the protection capability of the lights enclosure. When clean with spray water, power should be cut off, do not scrub the plastic housing with a dry cloth, to prevent static electricity.

LED flood lights

Check whether the transparent parts of the traces of foreign impact, whether the rotection network are loose, desoldering, corrosion and so on of the traces of the protective network whether loose, desoldering, corrosive and so on. If so, should stop using, timely maintenance and replace.

Turn off the lights promptly if light source is damaged, and notify the replacement, so as to avoid the light source can not be started, otherwise, the ballast and other electrical components will be in the long-term abnormal state.

Lights used in humid environment, if there is water in the lights cavity,   should be promptly removed, replace the sealing parts to ensure that the protective performance of shell.

When open the lampshade, should open the lid after power off as the warning sign requirements.

Check whether the rubber seal hardened or become sticky, wire insulation is green or carbonized, insulation and electrical components are deformed or scorch marks after opening the cover. If you find these problems, should promptly replace.

How to choose high-quality solar street lights?

Poles: As for solar street lights are in the outdoor environment for long-term, can not avoid the wind and sun, which having quite high requirements on the poles of the process. After a high standard of hot-dip galvanized Q235 steel, and then spray by electrostatic, can without rust for 20 years. Of course, the thickness is also a hard target. Generally, 6 meters of poles need thickness more than 2.5mm.

Light source and controller: These two are the core parts of lights, a good light source with high lumens and low color attenuation, especially the energy-saving effect of LED light source is in line with the current road of green development. The controller is the brain part of the whole system, it has to control the work of other various parts, whether the controller is good or bad is the key to the whole solar street light.

Solar panels and batteries: solar panels as the part of the absorption of light, batteries store up the solar energy absorbed by the solar panels. Solar panels are divided into two kinds of monocrystalline and polycrystalline, because of their different conversion efficiency, cost is different, polycrystalline is more relatively economical. The battery is divided into two kinds of batteries and lithium batteries, in terms of life, lithium battery more stable, but the lithium battery have the higher requirements on the ambient temperature, this need to be considered under various aspects.

LED flood lights and LED spot lights are often being confused, LED flood lights are generally no lens, light angle is relatively large, and generally 120 °. Irradiation area of LED flood lights is relatively large, but the irradiation distance is not far. LED spot lights are generally have lens, light irradiation angle can be determined by the angle of the lens size. Irradiation area of LED spot lights is generally not very large, but the irradiation distance is relatively far.

Composition of LED flood lights:

Tempered glass, reflector, LED integrated light source (COB), LED power supply, die-cast aluminum housing.

Tempered glass:

There are two process, one is physical tempering and the other is the chemical tempering.

Physical tempering is taking the ordinary flat glass or float glass in the specified conditions and the environment, made after quenching or air-cooled fire processing.

Chemical tempering is by the ion exchange method to change the composition of glass surface of ordinary flat glass or float glass, so that the glass surface to form a layer of pressure stress layer, and processing.

Identification for good or bad: check the flatness, no bubbles, no inclusions, no scratches, no lines and fog spots, and other quality defects, the existence of such defects in the glass will occur deformation, reducing the transparency of glass, mechanical strength and thermal stability of glass in use.

Reflector:

Identification method: no distortion, no spin lines, no pinholes, bright surface, no obvious sand holes on surface, electroplating gloss should be good, plating thickness should be uniform.

LED integrated light source:

Identify the good or bad: through the microscope to see whether the chip is to require manufacturers, whether the chip size is the size that required. Chip includes sorted chip, chip, chips on tape, wafer, according to specifications of LED floodlights to confirm the good or bad. Glue, support, phosphor etc. composition also can determine the quality of LED products.

LED Flood Lights

LED Power Supply:

Identify the good or bad: First, we need to start from the data. LED power conversion efficiency and power factor determine the good or bad of power, the better power supply, the higher value. Insulation protection of non-isolated power supply is very important.

Die-cast aluminum housing:

Identify the good or bad: the housing determines whether the product heat is good in the future, whether the light failure is within the normal range. At present, many manufacturers never consider the product cooling problem. In order to reduce costs, many manufacturers are very demanding in the aluminum, and use some waste. Because customers simply can not distinguish the good and bad of aluminum. The best way to identify is through stability testing.

Standard method for inspection of LED flood lights.

Brightness check, test the product illumination with the meter far from the product one meter, whether the products illumination is consistent with the data that suppliers provided.

Light failure check, check the illumination value every day regularly with a light meter, whether the illumination is within the normal attenuation range.

Temperature check, check LED integrated light source with a thermometer near the 1 cm, whether the test temperature is in the range of 80 degrees, and then use the thermometer to test the surface temperature of LED flood lights.

Whether there is scratches, deformation in the part of the surface, whether there are fingerprints on the glass. Fingerprints can reflect whether the factory management is strict and product quality requirements are harsh.

The good or bad of product, lies in your request. Price is only a part of the product, a good product does not measure by the price, but the value.

The main factor that affects the luminous decay of the LED streetlights is the temperature of the LED streetlights, and as a cooling module cooling plate cooling fins, cooling module assembly is completed, need to add the paint outside the module in order to prevent climate erosion, but that will sealed the module heat back, resulting in poor heat dissipation and leading to LED luminance decrease, reduce the life of LED streetlights.

Heat dissipation of the LED streetlights has been the serious distress existing in the LED lighting industry, but also is the bottleneck of enhancing the life of LED streetlights, and is the main reason that current public works LED streetlights affect the acceptance of procurement units.

A few suggestions that can solve the luminous decay of LED streetlights:

Starting from the basic materials, solving the problem of high-power LED heat source from the inside to out. For example, when bonding the light-emitting components and aluminum substrate, the thermal conductivity of thermal plastic film or thermal pads to be as good as possible, but the choice of film thickness must be reasonable, rather than the thicker the better, because no matter how good the thermal conductivity are, it is no use when encountered the thermal resistance with the thick film. Not to mention the thermal film or soft thermal pads can not really close with the substrate, in fact there are many pores in the paste surface. Seriously reduce the efficiency of heat dissipation and heat conduction.

Choose the thermal plastic correctly, generally use the soft ceramic thermal plastic. This kind of thermal plastic can reduce the thermal resistance to a minimum, quickly spread the heat, reduce the ambient temperature of LED streetlights beads, significantly delay the occurrence of luminous decay and extend the life of LED streetlights. The plastic has a ductility, in the high temperature baking or reflow, it will change with the thermal expansion and contraction of aluminum plate, the stress is very small, will not cause the aluminum plate bent or explosion.

The external of the cooling module of LED streetlights should adopt soft ceramic cooling paint. This can be directly sprayed outside the LED streetlights and can adjust to different colors according to the needs of landscape design if the construction is convenient.

Floodlights as the replacement products of electric light source have been recognized by more and more people, and has also been applied in many areas.
Main features are as follows:

Features of LED floodlights:

The floodlights illuminate objects evenly from a specific point in all directions, and it is better to use it to compare bulbs and candles.
Floodlights can be placed anywhere in the scene. For example, it can be placed outside the scope of the camera, or inside the object. It is common to use many different colors of floodlights in the scene. These floodlights can shade shadow and mix it on the model. As the floodlight range is relatively large, the irradiation effect of floodlights is very easy to be predicted, and this light has many auxiliary purposes.

What are the differences between the floodlights on the market?

Floodlight brightness (MCD) is different, the price is different. LED for LED floodlights should meet the laser class Ⅰ standard.

Floodlights with anti-static ability with a long life, and thus with a high price. Usually the anti-static of floodlights is greater than 700V can be used for LED lighting. The LED with the same wavelength are same in color, such as the requirements
of the same color, the price is high. Producers who do not have LED spectrophotograms are hard to produce purely color products.

LED with different use has different luminous angle. Special luminous angle, the price is higher. Such as total diffuse angle, the price is higher.

The key of the quality is life, life is determined by the luminous decay.
Small luminous decay, long life, and high prices.

Illuminator of LED floodlights is wafer, different wafers, the price difference is very large. The Japanese, American wafers are more expensive, generally Taiwan and domestic wafer prices lower than Japanese, American.

The size of the wafer is expressed by the side length, the quality of large wafer LED is better than the small wafer. The price is proportional to the size of the wafer.

Ordinary LED colloid is generally epoxy resin, the LED added anti-ultraviolet and fire retardant is more expensive, high-quality outdoor LED lighting should be anti-ultraviolet and anti-fire. 

Practical application:

Have what inquirements and to buy what kind of LED floodlights, can use in home or yard, or engineering, or special occasions, the general household < explosive area

LED floodlight is mainly divided into shell and light source, the part can light is the light source, the quality of the light source can impact the brightness and luminous decay, the brightness of light can decay after used for half a year, it is the case that inevitably appear for each light, but the degree is different, good lights are in about 90%, some bad lights are in 60%
each year, it is not easy to use in second year, and with the serious luminous decay, affecting the glasses, making people dull, reducing office efficiency.

Shell is mainly related to the application of the occasion, such as dust index is not very high at home. But for shock, corrosion, water, etc., to see the corresponding IP index and learn what occasion will be used.
