LED street lights use solar energy as the supply of street lights, and some components such as solar panels, led street light controllers, and batteries are indispensable. Led street lights have the characteristics of environmental protection, pollution-free, low power consumption, high light efficiency, and long life. Therefore, led street lights will become the best choice for road lighting energy-saving transformation.
LED street lamp is a kind of high-efficiency solid-state light source formed by semiconductor PN junction that can emit light with weak electric energy. Under a certain forward bias voltage and injection current, it injects holes in the P area and injects into the N area. After the electrons diffuse to the active area, they are combined by radiation to emit photons, which directly convert electrical energy into light energy. Now Chang Hui analyzes the common failures of led street lights for everyone.
1. The whole led street light does not light up
LED street lights are used for outdoor lighting, often encountering high temperature, rainy, low temperature weather and other environments, and LED street light controllers are usually installed on the light pole, which is easy to cause a short circuit between the water inlet and the controller. First check whether there is a problem with the terminal of the controller. If the controller is damaged, check whether there is voltage and current output during normal operation of the battery board. If there is no output, replace the battery board.
2, the led street light source is not completely bright
First check whether there is any problem with the quality of the LED light source and whether there is any problem with the virtual welding of the light bead. If there is a change, it may be due to insufficient sunshine at the installation site and unreasonable overall configuration of the luminaire.
3, the lamp head flashes
This may be due to poor line contact, battery loss, and severely reduced power storage. If there is no problem, then the battery is damaged and the battery needs to be replaced.
4. Short lighting time
If the continuous lighting time is very short on rainy days. Under normal circumstances, the storage capacity of the battery is reduced and the storage power is insufficient. It is recommended to replace the battery.
5, the line problem. Although LED street lights do not need to be trenched, there are also wiring on some lamp arms. If the wiring is poorly connected, it will cause the lights to flicker, so the bad contacts should be checked and repaired in time.
6, the controller problem. When the LED street light controller fails, if there is no indicator light and the buttons do not work, there may be a problem with the controller. Controller problems may be caused by abnormal solar panel specifications, installation problems, or the controller itself.
In short, choosing a regular led street light manufacturer can guarantee after-sales service, and the maintenance of led street lights must also be a professional manufacturer. If there is a problem, you can also replace the ordinary led street light manufacturer free of charge during the warranty period.
