bai: It is time to test whether the power supply circuit that supplies the LED power supply du is not.
If there is no output voltage of the power supply after the DAO lights out, it is a problem with the power supply circuit and needs to be replaced or repaired. If the output voltage of the power supply is normal, but the lamp is not on, it is the problem of the LED lamp bead or current limiting resistor, which means that an LED lamp or current limiting resistor bead has a circuit breaker fault due to its own heating after working for two minutes, when the power is turned off, the temperature of the LED or current limiting resistor drops down after the circuit stops working, it can work temporarily for a short time, and the faulty LED or current limiting resistor needs to be found and replaced.
1Lighting in all bathrooms needs to be bright and soft, free of shadows and glare, and feel clean and relaxed. LED downlights or LED ceiling lamps should be used in the ceiling, with compact fluorescent light sources, to achieve the effect of excellent color rendering and uniform light color, and all lighting appliances should have waterproof, moisture-proof and anti-fog functions to avoid corrosion and blocking. An independent lighting must be set up next to the makeup mirror as a local lighting supplement to ensure the illumination required for shaving and makeup. >>>More
You first check whether the switch wire is active, if not, it is the LED starter or light strip failure, it is best to find a professional acquaintance, pay attention to safety!
There is a driving power supply and an LED light source in the LED lamp, and the lamp is not lit when the drive power supply or the lamp source is faulty.
1. Check the ceiling lamp and power wiring lines. Be sure to cut off the power supply before checking the line to avoid any possible hazards. Then open the lampshade and check if the lamp fitting is loose, it is best to take the lamp off and reinstall it again. >>>More
2 reasons, 1 is the individual LED lamp beads burned out, you go up to remove the cover, see the LED lamp beads on the sealing board, there are no individual blackened inside, discolored and blackened are bad, if the number of bad is small, you can directly short both ends, you can continue to use, with my number too much, can not be directly shorted, 2 is the drive power supply is broken, all the lamp beads are not damaged in appearance, that is, the drive power supply is broken, you can only buy a new lamp to replace it.
