Key Specifications/Special Features:

Technical principles:

Traditional LED street lamp design of the main design focus on the number of lumens in the LED, while the heat is less concerned about the heat. In fact, the number of lumens of LEDs is increasing rapidly. In 2009, the number of single-turn lumens of LED production has reached 100 lumens, and this value is growing rapidly. Corresponding to the corresponding theory of heat transfer theory has matured, we can use the heat transfer means are basically clear: conduction, convection, radiation and phase change heat transfer. Therefore, in the heat or heat problems, we can take measures are visible, limited.

LED street lamp cooling technology, the general use of the way for the thermal plate, is a 5mm thick copper plate, in fact, is the temperature plate, the heat are temperature off; also installed heat sink to heat, but the weight is too large. Weight in the street lamp system is very important, because the street is 9 meters high, if the risk is too heavy, especially in the typhoon, the earthquake may be an accident. Domestic manufacturers use the world's first needle-like heat dissipation technology, needle-like radiator Of the thermal efficiency than the traditional sheet radiator has greatly improved, can make LED junction temperature than ordinary radiator 15 ℃ above, and waterproof performance is better than ordinary aluminum radiator, while the weight and volume also improved The In addition, for high-power LED lamps developed graphite heat sink also has good thermal conductivity and thermal performance.


Cooling methods are:

Natural convection cooling, the installation of forced cooling fan, heat pipe and heat pipe heat and so on. Install the fan forced cooling system complex, low reliability, heat pipe and loop heat pipe cooling method cost is high. The street lights with outdoor use at night, the cooling surface is located on the side and the size of the smaller restrictions are conducive to the natural convection heat the advantages of air, so LED lights recommended as far as possible to choose the natural convection cooling method.


Technical standard:

1. Light conversion rate of 17%, (per square solar energy of 1000W, the actual utilization efficiency of 170W)

2. Market street lamp lens material for the improvement of optical materials, transmittance ≥ 93%, temperature -38- +90 degrees, anti-UV UV `yellowing rate of 30000 hours without change and so on.

3.LED street lamp, mainly used for LED lights of the lens, the spot is rectangular, the material is PMMA optical materials, transmittance ≥ 93%, temperature -38- +90 degrees, anti-UV UV `yellowing rate of 30000 hours no change Wait,

4. The average illuminance of the uniformity of road surfaceilluminance is 0.48 and the ratio of light spot is 1: 2.

5. Meet the road illumination. (The actual 1/2 center spot to 25LUX, 1/4 center light intensity to 15LUX, 16 meters away from the minimum light intensity 4LUX, overlapping light intensity of about 6LUX.

6. It has a very good application prospect in the new city lighting. The depth of the dimming, and the color and other features will not change due to dimming.

7. Adapt to humidity: ≤ 95.
