Led driver with brightness control1/10/2024 ![]() The DC voltage controller receives DC input voltage from DC power supplier and sends out DC voltage controlled by the brightness controller. The brightness sensor senses brightness at the place where the brightness sensor is placed and sends the brightness information to the brightness controller. The infrared receiver transfers the parameter information to the brightness controller. The infrared controller is for setting parameter and sending the parameter information to the infrared receiver. This device consists of 5 parts, namely, infrared controller, infrared receiver, brightness sensor, brightness controller, and DC voltage controller. The present invention provides a brightness control system for LED lighting device that can remotely and manually or automatically control the brightness of the LED lighting device.
