Description

technical field

[0001] The invention relates to LED driver technology, in particular to an LED driver based on Internet of Things technology and an implementation method thereof. Background technique

[0002] LED has excellent dimming performance, coupled with the development of Internet of Things technology. There is a growing demand for smart LED drivers. However, in practical applications, there are still many problems in terms of dimming performance, safety, stability, and humanized control. Through the application analysis of the existing intelligent LED driver, there are the following problems:

[0003] 1. The dimming drivers on the market are mainly based on PWM (pulse width modulation) output. Due to the influence of the driving circuit, there are stroboscopic, dimming resolution and poor dimming linearity;

[0004] 2. The intelligent LED driver circuit includes power supply, wireless module, sensor, dimming drive and other circuits. The lack of effective isolatio...
