How to accurately replace LED bulbs

1. In general, the service life of led tube is more than 50,000 hours, and the daily lighting time is about 10 hours, which can be used for about 13 years. But this is just a theoretical estimate. In fact, when using led ceiling light, we must also consider the heat generated by the led chip and the impact of the impact current on the led diode.

2.Excessive current is still a characteristic of diode, which can easily make led breakdown. Then, these elements will lead to the destruction of the led lights. In considering these principles, when we use led ceiling lights, we must learn to prevent the factors that lead to led ceiling light damage.

3. Turn off the switch and remove the led ceiling light's housing under the sponsorship of a folding ladder to check if the light has black spots.

4.If so, it is likely that the bulb has been damaged and must be modified. This kind of LED light can be bought in hardware stores. It is recommended to choose a well-known brand.

5.If the lamp is still intact, try tightening the lamp connector to see if there is bad contact. This situation is also relatively simple and easy to happen.

6. If none of the above problems occur, you can check to see if the ballast is intact, if there is a burnt smell, and if the ballast has a dark burnt appearance.

7. if this is the case, ballast is likely the problem. Just switch one. Ballasts are more expensive than lights.

8. check if there is power to the touch head of the led light, if not then there should be a problem with the switch or circuit.

9. the internal structure of led lights is very simple. 3W led lights are three small 1W lights connected in parallel. There is a fixed interface between the normal driver and the LED light.

10.The LED lights don't light up for reasons not mentioned (not to mention no power). When there is power, 220v home electricity, if it doesn't light up, either the driver is bad or the LEDs themselves are bad. So you have to get a good driver and LEDs to try.
