Today, when we walk on the street, we can often see solar LED street lamps. They are widely used and can help people not hesitate in the dark. But they may also suddenly not flash. What is the cause? Next, let's make a good explanation for everyone.

1. Generally, the non flashing of solar LED street lamps can be divided into full non flashing and partial non flashing. If all of them do not flash, it is necessary to fully consider whether the LED street lamp is powered off. If it is, just pull up the switch. If the power supply is connected and the LED street lamp still does not flash, it is necessary to take full account of the LED street lamp driver. Usually, in this case, contact the street lamp manufacturer to disassemble and replace the driver with a new one.

2. If some of them do not flash, it is possible that some of the solar LED street lamp caps have internal equipment failures or damage. We should fully consider the following:

(1) Poor quality of LED chip products: At present, the quality of LED chip products on the market is uneven. Some LED chip products are of poor quality and have a short service life. They will be damaged within a short period of time, and will not flash naturally.

(2) The function of the heat pipe radiator is not very good: the function of the heat pipe radiator is not very good, and the internal heat of the solar LED street lamp head is too high, which exceeds the maximum temperature borne by the chip, thus causing damage to the LED chip and non flashing.

(3) Drive equipment damage: the damage of the switching power supply drive equipment will also cause other solar LED street light components to fail to operate normally.
