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.

No Picture

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.

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.

Welcome new and old customers to negotiate business with us.

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.

add to favorites Composition and Test Standard of LED Flood Lights 311301 Other $1.00 alternative energy

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.

No Picture

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.

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.

In the lighting market, many consumers are more concerned about the LED street lights price, so many manufacturers begin to attract consumers in low price. There are many small factories on the market, and setting the LED street lights price in low, which making so many big manufacturers do a difficult business, but we have to ask a question, that is, since a small factory has attracted so many consumers, why didn't they become a big factory?

In fact, the low LED street lights price in the market usually just play a bad role, lack of success, more than a loss. In the confrontational competition, the low LED street lights price can be the key factor of success.

We should understand from the other side, if LED street lights price without profit support, where the after-sales service and constant innovation! No profit support, LED street lights manufacturers will have no innovation, and the enterprise will be dead. No profit support, any business is difficult to survive.

LED street lights price surge will be continued:

For LED street lighting industry, 2016 can be described as mingling hope and fear. Small and medium enterprises are struggling; the other hand, the  influential brand is opening up the soil. It is expected that in 2017 the entire industry will really enter the shuffle stage, LED street lights price surge will be continued.

China's economy has entered a "new normal" today, the pursuit of development is constantly changing, the past pursuit of outdoor LED street lights development speed, the scale of the development, gradually give way to the pursuit of quality pf LED street lights, and gradually give way to the pursuit of a reasonable economic structure. Elimination of LED street lights with backward production capacity, emphasis for environmental management, will inevitably lead to key raw material price rise.

At the same time, the government may think about exploring the institutional long-term pollution control approach. Therefore, must not hold the fluke mind, should minimize the use of environmentally friendly materials in the research and development of LED street light products. Otherwise, may pay a higher price.

Characteristics of road lighting for solar lamps:

Road lighting has certain requirements, must meet the national standards of road lighting, to ensure the traffic convenient and safe.

Road lighting lamps generally use cut-off luminaire, semi-cut-off luminaire lamps to control the impact of glare on driver driving, a few occasions can also choose semi-cut-off luminaire lamps.

Road lighting design must be mainly on function, both appreciation-deserving. Plays the effect of beautifying eyes and lighting night.

Road lighting are more generally in low pole lights. Common lights are single-sided lights, combined lights, bilateral lights, lighting for wide road can also use high pole.

What are the seven major standards of solar outdoor lighting?

Road lighting standards of all levels of motor vehicle should be consistent with the provisions.   

The average illuminance for the triple carriageway road and carriageway road of non-motorized lanes shall be 1/2 of the adjacent motorway.

The average illuminance of roads and sidewalks for non-motorized and pedestrian-accessible residential areas should be 1~Zlx.

Urban road is divided into five of expressway, trunk road, secondary road, slip road, and residential area road.

When selecting a motor vehicle lighting standard, should consider the nature and scale of the city. Generally, the small and medium-sized cities can adopt the corresponding lower level according to the road type.

Motor vehicle lighting should meet the four evaluation indicators of average brightness (or illumination), brightness (or illumination) uniformity, glare restrictions and induction. Main routes for non-motor vehicles and pedestrians should meet the average illuminance evaluation index.

The brightness (or illuminance) values of motorway, non-motorized lanes, residential roads and sidewalks specified in the above paragraphs are maintenance values, for the road that new installation of light and lighting, the initial brightness (or illumination) of the road surface should be increased by 30% to 50%.

With the advancement of new rural construction, rural road lighting project is also the focus of each new rural construction, but accompanied by a variety of complex rural phenomenon, rural lighting project has many difficulties. And also affect the solar street lights price.

The following is the main reasons analyzed by zgsm for solar street lights price.

Investment issues about road lighting project.

The installation process is complex, digging earth and occupying the farmer's place, it is easy to cause the contradiction between the project and the villagers. Not easy for construction.

Electricity costs can not be resolved. Resulting in the lights are almost not bright after completion, can not achieve the actual use of lighting works.

The workload of later-maintenance is large and the cost is higher. Replacement of the parts and original device etc.

Large energy consumption, no energy-saving but also polluting the enviroment.

However, the solar street lights play the "star" role in the new rural construction.

Solar street light manufacturers don't have to lay complex lines in the installation in rural areas, just do a cement base, and then fixed with stainless steel screws. This product adopts highly efficient lighting design, with the advantages of high brightness, easy installation, stable and reliable, no cable laying, no conventional energy consumption, long life etc.

With the improvement of rural urbanization level, the demand for lighting
at night is also increasing, in order to meet the travel safety and convenience for rural people at night, the state vigorously promote the new rural road lighting project. However, how to choose the right solar street lights that suitable for the new rural construction in the new rural construction process?  Do we build solar street lights in rural areas?

Rural road analysis: the width of the road in rural areas are generally
within 10 meters, the normal width is about 4-6 meters;

Rural lighting requirements are not very high, under normal circumstances, as long as can illuminate the road;

Lighting time requirements are not very long, the general time in rural are 19: 00-24: 00; lighting time is generally: 4-6 hours;

Investment of cost, due to the pressure of rural funds, the general investment is not high, and because of solar street technology continues to mature and the cost is declining, solar street lighting can be the choice of rural road lighting;

In summary, the installation of solar street lights in rural areas, the solar street lights price is related with the width of rural roads, lighting requirements, lighting time and other specific reasons, therefore, in the choice of products should allow manufacturers to accurately understand the specific situation, in order to provide the solar street lights that most suitable for rural areas.

Although the cold environment is conducive to cooling for lights, but most people do not know there are more stringent technical requirements for the LED street lights, especially outdoor solar lights. At first, the cold areas with the low temperature, and the large temperature difference, drastic changes in hot and cold alternating and long-term cold environment for the work of electrical components must have a high degree of performance; Second, in the cold environment, the ice condensation phenomenon of LED street lights application can easily cause damage or failure to the street lights. We must take precautions to prevent ice condensation. So we should focus on solving the following key technical issues.

Hot and cold impact caused the failure of LED devices

As the LED street lights chip is solid device, there is chip, silicone (or resin), metal stent and the expansion coefficient between the lead is difficult to completely consistent, in the alpine region temperature changes under the hot and cold impact, will intensify the expansion and contraction of silica gel in the process of temperature changes, resulting in too large internal stress, easily increases the displacement of lights bead wire bonding point, lead premature fatigue, damage and caused failure. In this environment, the bonding with the poor state will appear desoldering, LED street lights chip  will appear layered off and other failuress.

Reliability Guarantee of LED Driver in cold environment

Driving power used in LED street lights with conventional design often can not start normally when low temperature in the cold environment and high failure rate in long-term low temperature operating environment. The main reason is that device selection problem of the power supply will change in the low temperature environment in the design phase, resulting in the drive can not start in low temperature or operate normally, so must choose the device with a better temperature characteristics. This will certainly increase the cost, but to ensure the work stability and life of the LED street lights.

Ice condensation protection problem of LED street lights in cold environment.

In the use of LED street lights in cold areas, due to the widespread use of aluminum light shells, the surface of the alumina is a hydrophilic material, particularly easy to form ice, resulting in LED street lights product failure or collapse to damage to power facilities, seriously affecting the safety pf road traffic. Measures reducing or avoiding the formation of ice includes: led street lights appearance are using sleek, smooth, flat design; absolutely avoid the snow or water accumulation; Use the material with excellent hydrophobic performance in the surface of LED street lights.

There is a battery insulation problem for outdoor solar lights. In addition to choose a battery with strong cold resistance, but also do a good job such as deep insulation.
