Anonymous users2024-01-24Use a slotted screwdriver to carefully pry open the plastic joint between the metal screw of the LED bulb and the main body of the bulb to keep it intact as much as possible to facilitate recovery after repair. After opening, check all the electronic components of the power conversion part first, if there is no problem, then power on to check its output voltage, I repair the 2W LED bulb, and the output DC voltage measured with a multimeter is, indicating that the fault is in the LED light-emitting component part. The DC measured here refers to the normal operating voltage after repair.
If the LED bulb light-emitting unit is disconnected from the power supply, the voltage measured by a wire is DC 320V. This is the normal working voltage and open circuit voltage of the 2W LED bulb of the "Kodi" brand.
Then try to separate the spherical bubble made of plastic from the plastic body to which it is attached. Since this part is glued firmly, it may not be able to separate it completely, and it will damage the plastic bulb, but even if it is broken, it does not matter. After repair, it doesn't affect the glow, it's just not good-looking.

1. Look at the chip.
At present, LED bulbs mainly have domestic chips, Taiwan chips, imported chips, the front LED bulb of Taiwan chips is more cost-effective, high-end families generally choose this, imported chips are relatively rare, the price is relatively high, and the quality of the bulb of domestic chips is not very good, and the price is relatively low. >>>More
Personally, I recommend not to make it colorful, and it is best to use white light directly. Usually just turn on the small lights!
This should also be matched with the overall style of your living room, and the living room is generally better than ordinary white. Neat and undecent.
Hello, 25 square meters need to use 9 W bulbs, the most critical depends on the parameters of the lighting effect you buy, that is, how much LM per W, you can calculate it like this: 1 square is about 70-90 lumens, for example, the light effect is 80LM W, then 3W bulbs can light 3 squares, 9 3W can light 27 squares. This is the regular algorithm. >>>More
White, of course! The living room will look brighter in white.
