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.

LED color temperature, the color of the light emitted by the light source is the same as the color of the light emitted by the black body at a certain temperature, the temperature of the black body is called the color temperature of the light source. The units are Kelvin. Glare refers to the visual discomfort caused by extremely bright objects or strong brightness contrast in the field of vision. Glare is an important factor affecting lighting quality. Synchronization, two or more than two LED lights in the specified time can normally run according to the way set by the program, generally refers to the internal control mode of LED lights.
