How long does solar street light last?
Recently, when choosing solar street lights, everyone will be concerned about this question: how long can solar street lights be used? This question cannot be simply answered with an exact data, because solar LED street lights are composed of 5 major parts, including solar panels, led light sources, solar controllers, solar gel batteries, light poles, and the life span of solar street lights depends on how long they can be used These five major decisions.
The service life of solar panels is more than 25 years, and the service life of light poles can be more than 30 years. Components with such a long service life can be completely ignored.
Secondly, the solar light controller can also be ruled out. First, the controller is cheap, convenient to source, and easy to maintain and repair. Second, the controller is not easily broken. As long as it is used correctly in accordance with the instructions, it will not cause much threat.
Here we mainly need to consider the service life of the LED light source and the battery. The correct use of the battery can have a lifespan of more than 5 years. The so-called correct use of the battery means that the manufacturer must consider the capacity of the battery when designing the configuration.
So how long is the service life of the LED light source? At present, a good quality LED light source has a luminous efficiency of 120lm/w and a service life of 100,000 hours. If the lamp is turned on for 8 hours a day, it can be used for 12,500 days, and it can be used for 34 years. Even if it is longer, if you just say 100,000 hours, the impression is too little. In fact, 100,000 hours is 34 years, so there is no need to worry about the longevity of LED lights.
