Abstract
A vehicle lamp includes a housing including a compartment having an opening. A reflective unit and a lighting unit are mounted in the compartment. The lighting unit includes a first circuit board and a first LED. A lens is mounted to a front end of the housing and covers the opening of the compartment. The reflective unit reflects light rays from the first LED to transmit through the lens. A heating unit includes a substrate made of a light transmittable material and a heating layer disposed on the substrate. A sensor is mounted in the compartment for detecting temperature. When the detected temperature is lower than a first predetermined temperature, the heating layer is activated to proceed with an electrical heating operation. When the detected temperature is higher than a second predetermined temperature, the electrical heating operation of the heating layer is stopped or gradually reduced.
