Abstract
A headlamp assembly which employs semiconductor light sources includes an optics chamber that is isolated from the surrounding environment to prevent the ingress of water, dirt, or other foreign materials into the optics chamber. At the same time, the headlamp assembly includes a plenum chamber, separated from the optics chamber, and airflow through the plenum chamber provides the necessary cooling for the semiconductor light sources.
