LED Solar Street Light Failure Analysis and Solution

LED street lights use street lights that use solar energy as a supply, and some components such as solar panels, led street light controllers, and batteries are essential. Led street lights have the characteristics of environmental protection, no pollution, low power consumption, high light efficiency, long life, etc. Therefore, led street lights will become the best choice for energy-saving road lighting transformation.

The LED street lamp is a high-efficiency solid-state light source based on a semiconductor PN junction that can emit light with weak electrical energy. Under a certain forward bias voltage and injection current, the holes injected into the P region and the electrons injected into the N region diffuse After reaching the active area, it emits photons through radiation recombination, which converts electrical energy directly into light energy. The following spectrum editor analyzes the common failures of led street lamps for everyone.

1. The entire led street light is off

LED street lamps are used for outdoor lighting, and often encounter high temperature, rainy, low temperature weather and other environments, and LED street lamp controllers are usually installed on the lamp post, which is easy to cause 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 light source of the led street light is not completely bright

First check whether there is any problem with the quality of the LED light source and whether there is a problem with the virtual welding of the light bead. If there is a change, it may be that there is insufficient sunlight on the installation site, and the overall configuration of the lamps is unreasonable.

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, the battery is damaged and needs to be replaced.

4. Short lighting time

If the continuous lighting time in rainy days is very short. Under normal circumstances, the storage capacity of the battery decreases and the storage power is insufficient. It is recommended to replace the battery.

5. Line problem. Although LED street lamps do not need to dig trenches, there are also wiring on some lamp arms. If the line connection is poor, it will cause the light to flicker, so the bad contact 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 button does not work, there may be a problem with the controller. The controller problem may be caused by abnormal solar panel specifications, installation problems, or the controller itself.

In short, choosing a regular led street lamp manufacturer can guarantee after-sales service, and the maintenance of led street lamps must also be selected as a professional manufacturer. If there is a problem, you can also replace the ordinary LED street lamp manufacturer for free during the warranty period.
