300 yuan of solar street light pictures1

Increasingly along with the global resources shortage, in order to reduce the consumption of the earth's resources, on one side of the road lighting is the traditional high pressure sodium lamp lights mass replaced with long service life, small energy consumption, high luminous efficiency of LED street light. In fact, a lot of people don't know about the LED road

with the growing shortage of global resources, in order to reduce the consumption of the earth's resources, the traditional high pressure sodium lamp has been long life, low energy consumption, high photosynthetic efficiency of LED street lamp is replaced. In fact, a lot of people don't know the LED street lamp, only know it is a new product, has the characteristics of good quality, low energy consumption. Questions about the LED lights have many questions? Street lamp manufacturers will answer these simple questions about led street lamp. 1. Is 1 light attenuation. Led lights? Low power led light attenuation is very severe, and light attenuation of up to 80%. If use for long time, generally are not allowed to use low power leds. In general, the use of more than 30 w high power led street light, the light attenuation would be much better. 2. Heat 2? Led street light? For light emitting diode is a semiconductor device, when the wafer due to the influence of temperature was reduced to 30% of the initial luminous flux, it will lose its shine meaning, that is to say, its life will end. In theory, power leds lamps lifespan is 30000 - 50000 hours, but the premise is good heat dissipation. It is worth mentioning that the domestic street lamp manufacturers have adopted the world's leading needle cooling technology. 3. Is 3. Led street light weight? Due to the led street lamps of high technical content, composition is complex, some high-power lamps and lanterns will be far more than the weight of the ordinary high pressure sodium lamp, so the higher request to the corresponding supporting material. Some leds lamps manufacturers, however, has been trying to leds lamp holder from about 30 kg weight reduced to 10 kg, and reduce weight has a tendency to decline further. 4. 4 because of their bright colors. Led lights are yellow or white? This should be based on actual needs. In general, people's eyes more resilient to yellow, and white light penetration is weaker. Street lamp manufacturers recommend is equal to or less than 7 meters high street lamp can use white light, highly greater than 7 meters high lamp it is recommended to use yellow leds.
