the common types and characteristics of household LED lights
LED lamps have gradually become the mainstream of the electric lamp market due to their high brightness, low energy consumption, and long life. Generally speaking, the failure rate of LED lights is very low, and the most common ones are these: the lights are off, the lights are dim, and the lights are flickering.

There are two forms of LED lamps, one is a ceiling lamp and the other is a light bulb. However, no matter which forms of a lamp, the internal structure is the same, which is divided into lamp beads and drivers.

Lamp beads, commonly known as "light-emitting diodes", are the most commonly used electrical components in electricity, and are also the illuminators of LED lights. The number of them determines the brightness of LED lights. Another is the driver, which can be understood as the combination of the ballast and the take-off of the previous fluorescent lamp. Generally, the driver is invisible on the outside, and its function is constant current, step-down, rectification, filtering, and so on.

When the LED lights in your home are not on, the first thing to look at is whether there is a problem with the circuit. If it is a newly installed LED lamp, you should use an electric pen to measure it, and then start the following maintenance after eliminating the circuit problem. The followings are common LED light failures and how to fix them.

LED light does not light up

Most of the LED lights do not light up because of the stupid driver problem. The LED lights have higher requirements on current and voltage. If the current and voltage are too large or too small, the lamps cannot be lit normally. If the lamp bead does not light up after turning on the light, then you need to buy a driver to replace it.

LED lights dimmed

The problem of dimming the LED light should be solved together with the previous problem. After eliminating the problem of the driver, check whether it is the problem of the LED lamp bead. The LED lamp beads are divided into circles and circles, each circle is connected in series, and the circles are connected in parallel; if a lamp bead is burned in a circle, then this circle will not light, or If one grain is burnt every lap, then the entire LED light will not light up.

Note: There is a black dot in the middle of the burned lamp bead. Of course, if there are not many lamp beads burned out, you can solder the two soldering legs behind the burned lamp beads together with an electric soldering iron.

LED light flashes

First of all, we need to rule out whether it is a line problem. If there is no problem with the line, it is generally the LED lamp that generates a self-inductive current. The easiest way is to buy a 220V relay and connect the coil in series with the lamp to solve the problem.
