Why is solar street lamps LED light source?

Why is full of solar street lamps LED light source? 1, LED luminous efficiency of LED light of high efficiency, the efficiency can be 100 lm/W - 200 lm/W, it is at this stage all the leader of the light source, so high efficiency for solar street lamps are limited power output production

why all LED light source, solar street lamps?

the solar street light is more popular in recent years a street lighting equipment, on the basic principle and general road street lamp is similar, but the commonly used electric energy is from the sun, don't have to connect power, solar street light except application of solar power solar panels, a feature that is used as light source, LED all basically all application LED as light source, solar street lamps, is this why?

1, LED luminous efficiency

the LED light of high efficiency, the efficiency can be 100 lm/W - 200 lm/W, it is at this stage all the leader of the light source, so high efficiency for solar street lamps are limited power output larger lighting lamps and lanterns of the actual effect, to make the road more light.

2, the LED small

LED efficiency, matching means loss is small, all the light source in the whole process of light, are caused by certain calorific value, and cause less calorific value of LED, heat loss also will be smaller.

3, the LED is working voltage

solar street lamps system software working voltage is 12 v or 24 v, the working frequency of the LED is working voltage and alternating current (ac) is commonly 3 v, according to the method of series and parallel working voltage control can be in need of working voltage, is very convenient.
