Switched-mode control circuit for correlated color temperature based on linear drive LED lighting

摘要

A switched-mode control circuit for correlated color temperature (CCT) based on linear drive LED lighting, including a switched-mode CCT control module, a linear drive control module, and an LED lighting module which is connected with the switched-mode CCT control module and the linear drive module. The switched-mode CCT control module is used to control and adjust the CCT of the LED lighting module, so that the LED lighting module emits light with different CCTs, and it may or may not have a memory function. The linear drive control module is capable of controlling and adjusting illuminance of the LED lighting module. The control circuit has a simple design and enables the adjustment of both the CCT and the illuminance, promoting the user experience.
