Abstract

A multifunctional LED dimming interface circuit provided by the present invention includes: a dimming signal output module, a micro control unit module, a dimmer interface module, the dimming signal output module is connected to the micro control unit module, and the micro control unit module is connected to the dimmer The dimmer interface module, the dimmer interface module leads out a plurality of dimmer connection terminals, and the present invention realizes a dimmer interface circuit applicable to 1‑10V by automatically identifying the dimmer type connected to the dimmer interface At least two of the three dimming types, PWM dimming and step dimming, provide more flexible options for the dimming scheme of the LED lighting device and the selection of dimmers.

Description

technical field [0001] The invention relates to the technical field of LED driving, in particular to a multifunctional LED dimming interface circuit. Background technique [0002] LED lighting devices are energy-saving and environmentally friendly, and have a variety of flexible dimming methods, making lighting solutions more diverse and intelligent. As a new generation of lighting sources, they have been widely used. [0003] In the current LED dimming scheme, it is divided according to the change form of the voltage signal. The most commonly used three dimming methods are: 1-10V dimming, PWM (Pulse Width Modulation, pulse width modulation) dimming and StepDim step Dimming, such as figure 1 Voltage shown for 1-10V dimming (V 1-10V ) changes and the corresponding brightness changes, such as figure 2 Shown is the voltage for PWM dimming (V PWM ) changes and the corresponding brightness changes, such as image 3 Shown is the voltage for StepDim step dimming (V stepdim )...
