Abstract

A lighting system and a method of operating a lighting module are described. The lighting module includes a heat sink a first LED element mounted on the heat sink emits light as a low beam pattern. A second LED element mounted on the heat sink emits light as a high beam pattern. A driver circuit electrically connected to the first and second LED elements to selectively supply electrical power for operation. The driver circuit is disposed to operate in a first and a second mode. In the first mode, to provide a low beam illumination, the first LED element is operated in a high power state while the second LED element is turned off. In the second mode, to provide a high beam illumination, the second LED element is operated in a high power state, while the first LED element is operated in a dimmed state.
