Anonymous users2024-01-23The lamp bead does not match the LED driving power supply, the normal single full 1W lamp bead bears the current: 280-300mA, voltage: , if the lamp bead chip is not full power, it will cause the light source strobe phenomenon, the current is too high The lamp bead can not withstand a light on and off, and the serious phenomenon will burn the gold wire or copper wire built in the lamp bead, resulting in the lamp bead is not lit.
2.It may be that the drive power supply is broken, as long as it is replaced with another good drive power supply, it will not flash.
3.If the drive over-temperature protection function, and the material heat dissipation performance of the lamp can not meet the requirements, the drive over-temperature protection will also have a flashing and extinguishing phenomenon at the beginning of the work, for example: the 20W flood light shell is used to assemble the 30W lamp, and the heat dissipation work is not done well.
4.If the outdoor lamps also have a strobe on and off phenomenon, it means that the lamps are flooded. The consequence is that it doesn't light up when it flashes. If the drive is waterproof, it is just a matter of breaking the lamp beads and replacing the light source.

Anonymous users2024-01-18The switch is broken, or the first wire is not in good contact. I don't know how to repair it, I live a single door, and the general electrician will not come to repair it. Whoever installs it for you can find him free or paid warranty, and he has this obligation.
Generally speaking: the diameter of the chandelier should not exceed a quarter of the width of the living room (if your living room is 15 square meters, I estimate it to be 4 meters X 4 meters, then your living room is 4 meters wide, so the diameter of the lamp should not exceed one meter, about 800 mm diameter can be maintained) If it is a ceiling, etc., choose a square one with 400X800 is suitable. If it is round, it is recommended to use 600. >>>More

If you say it's a fluorescent tube, use rice, it's bright enough, if you want to be brighter, use a meter double tube, we generally use this at home, last time my friend's home decoration was decorated with a meter, 18W is very power-saving, LED is the future trend. If you have more questions, you can click on ID to consult.
LED wattage is small, brightness, more durable than the traditional one, relatively long life, you choose one headlight or two in the living room and dining room, and whether you want to install downlights or what. If it is a whole, then install a large lamp, a 3W small lamp, and the general light source is about 20. A dozen watts of kitchen and bathroom will do. >>>More
My family is the bull's, I didn't know that the bull's house has this bulb, it was the last time I went to the coffee library when I saw it, I thought it was very stylish, so I bought one, it was very good to use, the more it was lit, the brighter it was, and then the baby's study room was also installed, not dazzling, and the price was right.
