    If there's no problem with the power supply, maybe you're connecting more of the power supply in series, or maybe there's a problem with the wiring, 100% lighting.

    LEDs are mainly about electric current.

    There may be several reasons why it does not light up, and you need to check them one by one

    1.The current fluctuation caused by voltage instability will cause the instantaneous current to exceed the maximum current used by the LED lamp beads, resulting in the breakdown of the LED chip.

    2.There is a problem with the power supply of lighting, the service life of the general power supply is generally 1000-6000 hours, and the life of the LED is about 20000 hours, and the voltage of the LED is about 3V, and the power supply can not be reduced and the voltage is too high. Cause the LED chip to break down and not light up.

    3.There is something wrong with the design of the lighting. LEDs are small and expensive devices, and the start-up voltage and current are very small.

    If the design of series and parallel connection is unreasonable, it will cause the whole lamp to cause a large voltage or large current impact at the moment of starting. Leads to the breakdown of the LEDs, dead lights.

    4.Poor contact. It's the same as the normal one, it's not a dead lamp. It is the poor contact of the aging of the line.

The life of the LED lamp is very long, if the lamp bead is broken], the cause should be identified, and after the cause is found and the symptom is solved, the damaged lamp bead should be replaced with the same lamp bead, so as to ensure that it will not be damaged again after replacement.

If it is slightly bright after it is turned off, it means that the switch is connected to the zero line, and you can switch the fire and zero line of the entrance line.
