How to change the LED light bulb? Change LED lights

We will be at home now, or in the office, in the mall, there are many places to see the presence of LEDs. LEDs and the like are used to illuminate. Because of our widespread use, there have been some bad things in the light bulb . Xiaobian here said how to change the light bulb under the led light .

The LED lamp is an electroluminescent semiconductor material chip, which is cured with silver or white glue to the bracket, and then connected to the chip and the circuit board by silver wire or gold wire, and sealed with epoxy resin to protect the inner core wire. Function, and finally install the outer casing, so the LED lamp has good seismic performance.

LED bulbs are short for Light Emitting Diode, a solid-state semiconductor device that converts electrical energy into visible light, which converts electricity directly into light.

How to change the bulb correctly?

1. Generally speaking, the service life of LED tube is more than 50,000 hours, about 10 hours per day, which can be used for 13 years. But this is only a theoretical estimate. In fact, when using a led ceiling lamp, it is also necessary to consider the heat generated by the LED chip and the impact of the inrush current on the LED diode.

2. Excessive current is still very easy to break down the diode characteristics of led. Then these factors will cause the led light to be damaged. When considering these principles, we should learn to avoid the factors that cause the damage of the LED ceiling lamp when using the led ceiling lamp.

3. Turn off the switch. With the help of the folding ladder, remove the outer casing of the led ceiling light and check if the light tube is dark and dark.

4, if there is, it is likely that the lamp has been damaged, must be replaced, this LED tube can be bought in the hardware store, it is recommended to choose a well-known brand.

5, if the lamp is still intact, then you should try to tighten the lamp joint to see if there is a bad contact, this situation is also relatively simple operation, it is easy to happen.

6. If none of the above problems occur, check whether the ballast is intact, whether it has a burning smell, and whether the ballast has a black burnt appearance.

7, if there is, then a big possibility is the problem of the ballast, just replace one, the price of the ballast is more expensive than the lamp.

8, is to check whether the contact head of the led light has electricity, if not, then it should be a switch or line problem.

9, the internal structure of the LED lights do not need to pay attention, interested can be taken apart to see, very simple. The 3W LED lamp is a parallel of three 1W small lamps. General drives and LED lights have a fixed interface.

10, the LED light does not light up, the reason is not to say the other (not to say no electricity), 220v household electricity in the case of electricity, if not lit, it is either the drive is broken or the LED light itself is broken. So try to get a good driver and LED lights.

11, LED lights are on the ceiling, we need a small ladder or stool to approach it, but how to remove it. Xiaobian is doing this drop: insert a small suction cup on the screwdriver, use the suction cup to suck the bottom of the led light, and easily suck it down.

12. Be careful when the LED light is removed. There are two spring buckles on the back, don't hurt yourself.

13. Remember a bit! The power is off. No joke.

The above content is, how to teach everyone when using LED lights, LED bulbs are broken, you want to change a new bulb, how should we be the right way. This content is also provided by the decoration home network, and you can pay more attention to us in the future, thank you!
