Many solar street lamps use LED street light source. Why should solar street lamp use this kind of light source? What are its advantages?

First of all, the luminous efficiency of LED has reached 120lm / W, exceeding the typical value of energy-saving lamps. It will make led one of the most efficient light sources. Secondly, power LED has unidirectional radiation characteristics. Most of the light energy emitted by it can reach the object directly without reflection, so as to maximize the light energy and greatly improve the efficiency of lamps and lanterns. LED has a long life and is green. At present, the average trouble free working time of the power LED that can be purchased is more than 50000h; if it works 12h a day, it can be used for 10 years. Almost all of its waste can be recycled. This not only saves energy, but also saves resources and protects the environment. The waste of other light sources will cause environmental pollution, especially after the waste of fluorescent lamps, the mercury in the lamps will cause serious pollution to the environment and water sources.

LED light source can achieve no flicker, no ultraviolet, very low thermal radiation, no harm to human eyes. LED is very suitable for indoor lighting or lighting where people need to work and study for a long time, In the part of luminous efficiency, because the traditional light source is 360 ° radial light source, part of the light has not been effectively used, so the traditional light source used in unidirectional lighting lamps has a luminous efficiency loss of more than 30%. Different from the traditional light source, LED is a 180 ° unidirectional light source, and the light emitted can be fully utilized.
The above is about the advantages of solar street lamp using LED street light source.
