Many solar street lights use led street light sources. Why do solar street lights use such light sources? What are the advantages? Below we Jiangsu Hengyuan Lighting for your reception of the advantages of led street light source.
First of all, the luminous efficacy of led has reached 120Lm / W, exceeding the typical value of energy-saving lamps. It will make LED one of the most luminous sources of light. Second, the power type LED has unidirectional radiation characteristics. Most of the light energy it emits can reach the object directly without reflection, so that the light energy can be maximized, which greatly improves the efficiency of the lamp. Led has a long life and is green. At present, the average trouble-free working time of the power type led can be more than 50,000h; if it works 12h every day, it can be used for ten years. Its waste can be almost completely recycled. This not only saves energy, but also saves resources and protects the environment. When other light sources are discarded, the environment will be polluted. Especially after the fluorescent lamps are discarded, the mercury in the lamps will cause serious pollution to the environment and water sources.
What are the advantages of using streetlights for solar streetlights?
Led light source can achieve no flicker, no ultraviolet light, very low heat radiation, no harm to the human eye. Led is very suitable for indoor lighting or lighting that people need to work and study for a long time. In the part of luminous efficiency, since the traditional light source is a 360° radial light source, part of the light is not effectively used, so the traditional light source is used in The luminous efficiency of the unidirectional lighting fixture has a light refraction loss of more than 30% in use. Unlike the conventional light source, the LED is a 180-degree unidirectional light source, and the emitted light can be completely utilized.
