Title:
QUICK SWITCHING CIRCUIT FOR BRIGHTNESS OF LIGHT SOURCE
Document Type and Number:
WIPO Patent Application WO/2023/231109
Kind Code:
A1
Abstract:
The present application provides a quick switching circuit for brightness of a light source, comprising a communication module, a main control module, a digital-to-analog conversion module, a multi-path current buffer module, a constant-current adjustment module and a light source module. The communication module is connected to the main control module; the digital-to-analog conversion module is separately connected to the main control module and the multi-path current buffer module; the multi-path current buffer module is separately connected to the main control module and the constant-current adjustment module; the constant-current adjustment module is connected to the light source module. According to the present invention, by buffering current values corresponding to multiple brightness values, directly switching can be performed by means of hardware when needed; thus, the time required for switching the brightness of a light source is greatly shortened, the stroboscopic speed of a light source controller is also greatly improved, and the present invention has high market promotion value.
