It’s reported that Sharp Corporation has designed and will introduce the LR56001 LED controller for LED ceiling lights which can independently control up to three types of LED lights including cool white, warm white, and night light with each at the desired level of brightness.
By adjusting the brightness of cool white and warm white lights ,the user is able to change the color emitted, anywhere from a warm red color to a cool light blue color.
In particular, the LR56001 has a built-in chopper circuit, which prevents power loss even when the forward voltage of the three types of LED differs.
