LED Driver

LEDs are characteristic-sensitive semiconductor devices and have negative temperature characteristics, so they need to be stably operating and protected during application, resulting in the concept of driving. LED devices have very strict requirements on driving power. Unlike ordinary incandescent bulbs, LEDs can be directly connected to 220V AC mains.

Constant current drive of LED

LEDs are driven by a low voltage of 2 to 3 volts, and complex conversion circuits must be designed. LED lights for different purposes should be equipped with different power adapters.

In the international market, foreign customers have very high requirements on the efficiency conversion, effective power, constant current accuracy, power supply life, and electromagnetic compatibility of LED drive power supply. To design a good power supply, these factors must be comprehensively considered, because the power supply is in the whole lamp. It is as important as the human heart.

When using LED as a display or other lighting equipment or backlight, it needs to be driven by constant current, the main reasons are:

1. Avoid driving current beyond the maximum rating, which will affect its reliability.

2. Obtain the expected brightness requirements and ensure the consistency of the brightness and chromaticity of each LED.
