It is well known that LED light source is a typical green illumination, which does not cause light pollution to surroundings. A good solar led lamp brings high brightness lighting performance, while emits much less heat. The quality of led lamp head is very important. Here are some basic things we can check.
External structure: The lamp head of solar street light usually adopts led light source. When installing street lamp head, we must consider its size. If the size is too big, the socket may not be able to hold the solar lamp safely, which may cause security risks. High quality solar led street lamp is made of die-cast aluminum. This material meets the needs of the luminaire while making the lamp head lighter and safer. The aluminum led solar street light has very high hardness. It is relatively firm and durable. Even in the wind and rain, there will be no loose parts or other safety hazards.
Internal circuit: When something wrong happened with internal lighting system, here are some tips that may be helpful. Firstly, check built-in constant current source. If the street solar lamp has built-in constant current source, connect the positive and negative terminals of the lamp output directly to the battery output. If it is a lamp head without constant current source, try to replace the original controller. Once the problem is fixed after replacement, there must be something wrong with the original street solar light controller. You should also check if there is any problem with the lamp head connection or lamp bead.
