1. The whole lamp is not on. Solar high-pole lamp used for outdoor lighting, often encounter high temperature, rainy, low temperature and low snow climate, and solar high-pole lamp controller is usually installed on the lamp pole, easy to form the phenomenon of short circuit from water into the controller. First, it investigates whether the terminal of the controller is rusty. If the controller is damaged, the battery voltage is not measured. For example, in a 12V solar high pole lamp power supply system, if the battery voltage is less than 10.8V, the battery is no longer stored and needs to be replaced. Then check for voltage and current output under normal operating conditions of folding ceiling. The rigid panel will not be damaged. Replace the panel. All of the above can be done. We should check the light source and only supply it with electricity to see if it is lit, and then replace the light source.
2. The lamp head flickers. The cause of this failure is poor line contact, insufficient battery power and serious decline in storage capacity. Batteries should be replaced without circuit problems.
3. Short lighting time, short duration of rainy and cloudy days. Usually batteries can store power drops and form storage feet. Reasonable battery replacement.
4. The light source of the solar pole is not very bright. Many solar high-pole lamps use dot-matrix LED light sources. In addition to the quality problems of LED light source itself, some beads virtual welding will form this situation. The solution is to replace the corresponding lamp beads, solder firmly or replace the whole lamp head.
