Nowadays, when people choose solar road, etc., how long can solar road, etc. be used? Solar led street light can not simply answer the exact number, according to the solar panel, LED light source, solar controller, solar colloid battery, light, solar street light life to decide.
The life of the solar panel is more than 25 years, the life of the lamp table is more than 30 years, the life of such a long life parts can be completely disregarded. Second, the solar light controller can be excluded.
First, the controller is cheap, easy to source and easy to maintain, and second, the controller is not easy to break. If used correctly according to the instructions, it will not pose a great threat. The main consideration here is the life of the LED light source and the battery, the correct use of the battery, the life of up to 5 years or more, the so-called correct use of the battery, meaning that the manufacturer in the design configuration to consider the battery's ability to withstand.
At present, good quality LED light source can produce 120lm / w of light efficiency, the service life of 100,000 hours, open 8 hours a day can be replaced to 12,500 days, adults can be replaced to 34 years. Such a long comparison if only say 100,000 hours, giving the impression of too little. In fact, 100,000 hours is 34 years, there is absolutely no need to worry about the life of LED lights is not long enough.
