The choice of light source for solar street lights and the comparison of different types

　　 The selection principle of solar street light source is mainly based on factors such as its suitability to the environment, high light efficiency and long life. In the face of solar operation, in order to improve the operating efficiency of solar power generation, people try to avoid choosing the power supply introduced into the inverter and adopt the DC input light source. The following is a brief comparison of several light sources commonly used in solar street lights, and a brief analysis of their respective strengths.



　　(1) With three primary color energy-saving lamps as the light source, its light efficiency reaches 60Im/w. Jiangsu Naite Lighting Electric Co., Ltd. is a manufacturer engaged in the production and design of solar street lamps and high-pole lamps. It has 20 years of experience in the production of solar street lamps and creates the best Professional solar street lamp manufacturer, contact number: 13805257308. , And the light color is good, the cost is low, the service life can reach 000h, and it is widely used.



　　(2) Led as a light source, its light efficiency can reach 60-80Im/w, its life span can reach 30,000h, it works at low pressure, without ultraviolet and infrared radiation, and its power is adjustable.



　　(3) As the light source, the high-pressure sodium lamp has a light efficiency of 100-120Im/w, 24000h, and because of its good fog permeability, it is more suitable for road lighting.



　　(4) Low-pressure sodium lamp as the light source, its light efficiency can reach more than 150Im/w, and the life span can reach 28000h, although the fog permeability is good, but the color rendering is poor.



　　(5) As the light source, the induction lamp has a light efficiency of 50-70Im/w, a life span of 40,000h, no flicker, and good color rendering.



　　(6) As the light source, the ceramic metal halide lamp has a light efficiency of 80-110Im/w, a life span of 12000h, and good color rendering.



　　 In addition to the above factors, the cost factor is also an important aspect of competition. For the LED street lights at the moment, considering the light efficiency, cost performance, color temperature, reliability, and lifespan, we think that the three-primary color energy-saving lamp as the light source is the most ambitious. The current lawn lamp Led is widely used as a light source.
