  • LED is very bright when just energized, after a period of time suddenly not bright or brightness attenuation, you can check whether the switching power supply is 12V LED misused into 24V. If there is no problem, check whether the input voltage of the switching power supply is 220V. If the LED brightness is high or low, check whether the input voltage and output voltage of the switching power supply are normal. Such as high voltage, will lead to LED burn out; If the voltage is low, the LED will not bright or brightness attenuation. If the user’s local voltage is very unstable, it is recommended that the user install a voltage regulator. If the noise is found in the use, it is likely that the quality of the drive power supply is not good, and the drive power supply can be replaced.
