ABSTRACT:
A headlamp lighting device is provided that allows for the adjustment of the size of the light beam and forward heat dissipation. The lighting device includes a housing, a light source provided on the housing for generating a light beam, an inner thermally conductive heat sink, and an outer heat sink member. The inner thermally conductive heat sink is disposed in thermal relationship with the light source. The outer heat sink member is in thermal heat transfer relationship with the inner heat sink and disposed generally forward of the rear end of the housing for directing thermal energy generated by the light source towards the front end of the housing.
