LED energy-saving lamp drive power precautions


1. The quality of the LED energy-saving lamp drive power has a great impact on the lamps. Voltage and current have a great influence on the chip in the LED lamp, the life of the LED lamp, wavelength, luminous intensity, light decay, etc.led controller ic, so the quality of the power driver is also an important factor in the purchase process.


2. The chip of the LED light needs low-voltage DC to work, and generally needs a power supply to provide stable voltage and safe current. LED lights have built-in and external drivers.


3. Whether the LED built-in power supply or the external power supply is better depends on the use environment of the lamps and the actual requirements of the lamps. It depends on the power. If the power is large, a large heat dissipation area is required, and the temperature in the lamp body will be very high. In this case, it is recommended to use an external


4. For the driving power supply of LED lights, it is generally divided into two types: constant voltage source and constant current source. The best LEDT8 lamp uses a constant current source. LED lights are very sensitive to current, so constant current current has an impact on the luminous intensity of service life. And light decay helps a lot.
