Why do LED flat living room lights buzz when installing them

This is not a problem with the line, because the current consumption of the LED light is very small, and the influence of the line can be basically ignored. It may be a problem with the power supply circuit of the lamp, this kind of lamp generally uses a switching power supply to supply power to the LED, if the oscillating transformer in the power supply is not working properly, it will make a sound, you can change a power supply to try.

LED is in English.

lightemitting

diode light-emitting diode), its basic structure is an electroluminescent semiconductor material chip, cured to the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver wire or gold wire, and then sealed with epoxy resin around to protect the internal core, and finally the shell is installed, so.

LED lights have good shock resistance.

Pros and cons: Heat dissipation problems, if the heat dissipation is not good, the life will be greatly shortened.

The power saving of low-end LED lamps is still lower than that of energy-saving lamps (cold cathode tubes, CCFLs).

The initial purchase cost is high.

Due to the strong directionality of LED light source, the special optical characteristics of LED need to be considered in the design of lamps.

LED fixtures are buzzing. The floor of the lamp is too thin, or the roof is uneven. The installation is that the screws are fixed too tightly, resulting in the deformation of the lamp body, so that a hollow bulge is formed in the middle of the lamp, and the LED light strip has a large power when the light is turned on, forming a magnetic field, resulting in resonance.

Solution: Install the lamp, the hole position is correct, do not let the chassis deform, just that. There is no problem with the driver and the light bar, and it can be solved by mastering certain skills when installing.

In the final analysis, it is because the picture is cheap when buying lights, and this situation mostly appears between 200-400 yuan lamps and lanterns, so it is good to pay attention to them when buying lights.
