LED is a low voltage driver of 2-3 volts, and complex conversion circuits must be designed. Different LED lights for different purposes must be equipped with different power adapters.
In the international market, foreign customers have very high requirements for the efficiency conversion, effective power, constant current accuracy, power supply life, and electromagnetic compatibility of LED drive power supplies. Designing a good power supply must comprehensively consider these factors, because the role of power supply in the entire lamp is as important as the heart of a person.
When using LED as a display or other lighting device or backlight, constant current drive is required for the main reasons:
1. Avoid driving current exceeding the maximum rated value, which may affect its reliability.
2. Obtain the expected brightness requirements and ensure the consistency of brightness and chromaticity of each LED.
