Make solar LED street light lighting equipment that people can use at ease

1. The characteristic of the solar LED street light source itself is light unidirectionality, no light diffusion, and its unique secondary optical design, illuminates the light of the LED light source to the required illumination area, further improving the light efficiency to achieve Energy-saving lighting purposes; 　　2, the light source efficiency of solar LED street lights has reached 100lm/W, and there is room for further development, with a theoretical value of 250lm/W. The luminous efficiency of high-pressure sodium lamps increases with the increase of power. Therefore, the overall luminous efficiency of LED light sources is greater than that of high-pressure sodium lamps; 　　3, the light color rendering of solar LED street lights is much higher than that of high-pressure sodium lamps, and the color rendering index of high-pressure sodium lamps It is only about 23, and the color rendering index of the LED light source is as high as 75, so to achieve the same brightness, the illuminance of the LED light source can be reduced by more than 30% than the high-pressure sodium lamp on average; 　　4. 3%, it can still meet the road illumination requirements after 10 years of use, and the high-pressure sodium lamp has a large decline, which has been reduced by more than 30% in about a year. Therefore, the design of the LED light source can be lower than the high-pressure sodium lamp; 　　5, solar LED The street lamp has an automatic control energy-saving device, which can achieve the greatest possible reduction in power and save energy under the condition of satisfying the lighting requirements at different times. Moreover, the LED light source is a low-voltage device, and the voltage for driving a single LED is a safe voltage. It is 1 watt, so it is a component of a safe power supply.
