Solar street lamps of $101

Nowadays, most of the solar street light configuration of the light source is LED lamp holder, in the actual installation process, hard to avoid can appear products out of the question, for example light bead is not on, or power supply damaged, or the controller is broken, and so on. The installation site of t

today, most of the solar street lamps light source is a light emitting diode lamp holder. In the actual installation process, the inevitable product problems, such as light bead is not on, power supply damage or damage of the controller. So, installation site how teachers simply found the problem? There are usually two types: the built-in constant-current source and constant current source, which have no more than three or constant current source of lamp holder. Testing method of constant current source lamp holder: first of all, the lamp holder output directly connected to the battery positive and negative poles of the output side, when separated from the controller, can check whether the lamp holder is normal light. If it can't light up, then remove the built-in constant-current source, try again after replacement, or directly using the corresponding constant current control all-in-one. If it can normal light, means that the original built-in constant-current source is broken, otherwise, the lamp bead is broken. Without a constant current source lamp holder detection: also can be dealt with by the similar method above, can also try to replace other good controller of the same project. If the change is good, it means the original solar street lamps controller may have a problem, otherwise it is a cap lamp light source. Please check the lamp cap line if there are any problems, whether the lamp bead damage. Check the death light bulb. You can use the battery checking each 3 or 4 series of light bulbs. When the garden light [ jschindo。 com] Failure, first check whether the solar controller and the battery indicator light is bright, if not bright, fall off, check whether cable between controller and battery. If the cable is normal, using a multimeter to check the battery voltage. If the battery voltage is normal, this is the problem of the controller. Replace the controller, see if it work properly. Then check that the controller whether load indicator lights up, multimeter is used to inspect whether there is output voltage. If there is no voltage output, replace the controller. Finally, check whether the light emitting diode drive voltage at the input is normal, light emitting diode drive fuse are in good condition. If the fuse is good, the multimeter to check the light emitting diode drive of the output voltage is normal. If normal, please use led lamp holder to replace. If not normal, please use light emitting diode drive replacement.
