(1) the positive light is not lighted. Solar street lamp For outdoor lighting, it will encounter high temperature and rainy weather, low temperature and rain and snow. LED solar street lamp manufacturers The controller is installed in the lamppost, which is easy to cause the water inlet to the controller short circuit. First of all, if there is a rust stain on the terminal of the controller, if there is a possibility that the controller is damaged, there is no battery voltage measurement. If the 12V solar street lamp power supply system, the battery voltage is less than 10.8V, the battery will not be charged, and it needs to be replaced. Check whether there is voltage or current output when the battery panel is working normally. No battery panels are damaged, replace battery panels. None of the above is OK. Check the light source, only supply the light source, whether the incense is lit or not, then replace the light source.
(2) the lamp holder flickers. The cause of this failure is poor contact with the line, loss of battery power and serious reduction of storage capacity.
(3) lighting time is short and rainy days are short. The first is the decline of Bodhisattva battery storage capacity, resulting from Bodhi electric foot. Replace the reasonable first battery.
(4) the source of solar street lamps is not bright enough. Many solar street lamps use dot matrix LED light source. In addition to the quality of LED light source, some bead welding will cause this situation. The solution is to replace the corresponding bulbs, soldering firmly or replacing them all. The street lamp head 。 In addition, the insufficient lighting in the installation site and the unreasonable overall configuration of the lamps will seriously shorten the life of the solar street lamps. Reasonable installation of bad environment and rational allocation of solar street lighting system should be rationally chosen.
