Abstract
Implementations described and claimed herein provide a dual function illumination lamp in compliance with regulations for vehicular forward lighting. In one implementation, the illumination lamp includes a first reflector and a second reflector. The first reflector has a first reflecting region adapted to reflect light emitted from a first light emitting diode through an optics-free lens. The light reflected from the first reflecting region forms a first beam light pattern. The second reflector has a second reflecting region adapted to reflect light emitted from a second light emitting diode through the optics-free lens. The light reflected from the second reflecting region forms a second beam light pattern that is different from the first beam light pattern. In some implementations, the first beam light pattern is a low beam light pattern, and the second beam light pattern is a high beam light pattern.
