What are the advantages of using LED street light sources for solar street lights?

Many solar street lights use led street light sources. Why do solar street lights use such light sources and what are their 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, the power LED has unidirectional radiation characteristics. Most of the light energy it emits can reach the illuminated object directly without reflection, so that the light energy can be emitted to the maximum and the efficiency of the lamp is greatly improved. Led has a long life span and is environmentally friendly.

At present, the average trouble-free working time of power LEDs that can be purchased is more than 50,000 hours; if it works 12 hours a day, it can be used for ten years. Almost all of its waste can be recycled. This not only saves energy, but also saves resources and protects the environment. When other light sources are discarded, they will pollute the environment. Especially when fluorescent lamps are discarded, the mercury in the lamps will cause serious pollution to the environment and water sources.
The led light source can achieve no flicker, no ultraviolet rays, extremely low heat radiation, and no harm to human eyes. Led is very suitable for indoor lighting or lighting in places where people need to work and study for a long time. In the part of luminous efficiency, because the traditional light source is a 360° radial light source, some of the light is not used effectively, so the traditional light source is used in The luminous efficiency of one-way lighting fixtures has a light refraction loss of more than 30% in use. Unlike traditional light sources, the LED is a one-way light source with 180°, and the light emitted can be fully utilized.
