When the street lamp is maintained, some LED street lights will not light up. The reason is that there is a fault or damage inside the LED street lamp head. The following will talk about which street lamp head to choose when purchasing to reduce the probability of failure.

1. The quality of LED chips. The quality of LED chips on the market varies from good to bad, and some LED chips are of poor quality and low price, and have a short service life. When choosing high-quality branded LED chips.

2. Heat dissipation performance. If the heat dissipation performance of the LED street lamp head is not good, the internal heat of the LED street lamp head is too high, which will easily cause the damage of the LED chip and the phenomenon of non-lighting. When choosing the lamp head, choose a lamp with good heat dissipation.

3. Power drive. LED street lights need to turn the high voltage of the mains power to low voltage through the driving power supply, and this link has a greater test of the power supply performance, and the service life can be guaranteed by choosing a good quality power supply product.

If you want LED street lights to have a long service life, try to choose a street lamp manufacturer with good quality and guarantee when purchasing, and you should also pay attention to regular maintenance, so as to ensure the stability of LED street lights.
