How to check the quality of solar street lamp head

The lamp head of the solar street lamp must use the led light source. When installing the lamp head, we must consider its volume. If the volume is too large, the load on the socket will be great, and it is easy to cause safety hazards. LED lamp heads are relatively small in size because they are made of die-cast aluminum. This material meets the needs of the luminaire while minimizing weight and making the luminaire lighter and safer. The material of the led lamp head is die-cast aluminum. Its hardness is very high. Even in the case of wind and rain, it is very strong. There is no loose part, and there is no safety hazard. It is relatively durable. .

1: Check the built-in constant current source, one is without constant current source, and the lamp without constant current source is divided into 3 strings or more than 3 strings. If it is a lamp with a constant current source, connect the positive and negative terminals of the lamp output directly to the battery output.

2: If it is a lamp without a constant current source, try to replace other good controllers of the same project. If it is replaced, it means that the original solar street light controller may have problems. Check if there is any problem with the lamp head and check if the lamp bead is damaged. Check the dead lights and check the 3 strings or 4 strings of lights with a battery.

3: It is well known that LED light source is a typical green illumination source, which does not cause light pollution to the environment. Led light source is high brightness, even if it is light, it is much slower than ordinary lighting, so this is one of its advantages.
