Where are the main characteristics of the solar street light itself?

　　 What functions and characteristics does the solar street light have? The function aspect is its popular road lighting, which makes the citizens’ night travel safer. Solar street lights are a kind of equipment very suitable for outdoor road lighting. The products of Changhui solar street light manufacturers have improved their own characteristics. We will follow Briefly explain and explain for everyone: 　　1. The characteristics of the solar street light source itself: the light source has a unique secondary optical design, one-way light, no light diffusion, to ensure the efficiency of light, and the one-way lighting of the product The function makes the light perception of the lamp more extensive, and at the same time illuminates the light of the solar street lamp head to the area that needs to be illuminated, further improving the light efficiency. The light efficiency can be achieved through a special secondary optical design; 　　2, the light source is Decided the choice of solar street lamp installation area, now the LED light source efficiency has reached 90-110LM/W, and there is still a lot of room for development, the theoretical value reaches 250lm/W; and the luminous efficiency of high-pressure sodium lamps is only as the power increases. Therefore, the overall luminous efficiency of the LED street lamp head is stronger than that of the high-pressure sodium lamp; 　　3, the color rendering of the LED light source of the solar street lamp is much higher than that of the high-pressure sodium lamp. , After reaching the same brightness, the illuminance of the LED light source can be reduced by more than 20% than the high-pressure sodium lamp on average. The reasonable layout of the color rendering index can be used in more installation environments; 　　4, the light attenuation of the solar street lamp is small, one year The luminous decay is less than 3%, and it can still meet the road lighting requirements after 10 years of use. The high-pressure sodium lamp has a large decay, which has dropped by more than 30% in about a year. The problem of luminous decay has always been a problem restricting our development; LED is a low-voltage device. The voltage to drive a single LED is a safe voltage. The power of a single LED in the series is 1 watt. Therefore, it is a safer power supply than the use of high-voltage power supplies. It is especially suitable for public places and makes the life of solar street lights longer. long.
