Common failures and repair methods of new rural solar street lamps
March 14, 2022
Before repairing the solar street lamp, it is necessary to confirm which part is damaged first, that is, the preliminary inspection operation. The solar high pole lamp is generally composed of the following parts. The solar panel, the lamp, the battery, and the controller and the LED light source are inside the lamp. During this period, the controller has the highest probability of failure. The following solar high pole lamp repair companies and manufacturers have sorted out the common failures and repair methods of solar street lamps for us: 1. The whole light is off. Solar street lights are used for outdoor lighting, and often encounter high temperature, rain, low temperature rain and snow climates, and the solar high pole lamp controller is usually installed in the pole, which is easy to form a short circuit phenomenon from its water to the controller. First investigate whether there is water rust on the controller terminal. If there is a high probability that the controller is damaged, no battery voltage measurement is performed. For example, the 12V solar high pole lamp power supply system. Power storage, demand replacement. Then check whether there is voltage and current output under normal operating conditions of the folding solar panel. No new battery board is damaged, replace the battery board. The above is no problem, you should check the light source, only connect the power supply to the light source to see if it is lit, and replace the light source if it is not bright. 2. The lamp head flashes. The cause of this failure is poor line contact, battery power loss, and severely reduced power storage. Replace the battery when the line is okay. 3. The lighting time is short, and the duration of rainy days is short. Normally, it is the storage of the battery that can drop, and the storage foot is formed. Just replace the reasonable battery. 4. The light source of solar high pole lamp is not all bright. Many solar high pole lights use dot matrix LED light source. In addition to the quality problems of the LED light source, some lamp bead welding will cause this situation. The solution is to replace the corresponding lamp beads, weld firmly or replace the entire street lamp head.
