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...

AI Technical Summary

Problems solved by technology

[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 isolation between the circuits of each module will easily lead to mutual interference between strong and weak currents, high voltage in series and even electrical accidents;

[0005] 3. The existing control methods still rely too much on manual intervention. Compared with the traditional control methods, only the APP access control of smart phones is added.

The initiator of control still relies on manual participation, and the timeliness and intelligence level of control are still not enough
