Classification and characteristics of LED dimming power supply

What are the main types of LED dimming power supplies?

There are usually TRIAC dimming power supplies, Dali dimming power supplies, ZigBee dimming power supplies, 0/1-10V dimming power supplies, etc., and their respective advantages and characteristics are as follows:

(1) TRIAC dimmable power supply: constant voltage dimming mode and constant current dimming mode. Two modes are available. With active PFC correction, EMC standard design, smooth dimming, no flicker. Support front phase dimming and rear phase dimming; strong compatibility, triac standards are matched with mainstream dimmers and lighting control systems at home and abroad. (SCR is commonly known as: linear dimming, phase shift dimming)

(2) Dali dimming power supply: Constant voltage dimming mode Constant current dimming mode Two modes are available. Dali abbreviation: digital addressable lighting interface, with dual-stage PFC correction, high conversion efficiency, strong stability; circuit design in line with international certification standards, EMC guidelines, based on ST chip integrated design, integration scheme, simple and convenient wiring. Seamlessly compatible with domestic and foreign DALI dimmers and DALI control systems, standardized protocol schemes. Strictly follow the IEC (International Electrotechnical and Electronics Commission) 62386 standard (2009); smooth dimming, no node flicker, no flicker, design life of 60,000 hours, low working temperature rise, and theoretical life of more than 100,000 hours. The characteristic of DALI is that the system terminal control can accurately point-to-point control lights, and the system can identify the ID of each power supply; as long as the system is supported, the DALI power supply can give the system feedback precise points of failure; the port is easier to connect to the Internet to achieve remote monitoring.

(3) The ZigBee dimming power supply is embedded in the ZigBee module to achieve a wireless intelligent control dimming drive power supply with high efficiency, high controllability, and strong stability. It can be achieved by using wireless ZigBee, Wi-Fi, and other Internet of Things and IT technologies. Remote single light switch, dimming, scene setting, timing and other control functions.

(4) 0/1-10V dimming power supply: constant voltage dimming mode, constant current dimming mode, two modes are optional! Dimming range 0-100%; with active PFC correction, EMC standard design, stepless dimming, smooth bright and dark effects, seamless compatibility with all 0-10V 1-10V10V PWM dimmers and lighting control systems in the world .
