Abstract
A thin aspect lighting system and method are shown. The system and method include at least one module having a reflector that is generally elliptical in one cross-section and generally parabolic in another cross-section. Each module is adapted to generate at least one of a flat beam pattern, a high beam pattern or a low beam pattern, such as a low beam pattern with a kink or elbow. Also shown is a headlamp assembly having a plurality of modules that generate the same or a different light beam pattern. Manipulation and variation of facets or positions of various components, such as at least one light source provides improved characteristics in one or more of the light beam patterns.
Claims20
A lighting device of a vehicle, comprising:
- a primary reflector that is generally parabolic in a first section and generally elliptical in a second section, with the primary reflector used for a primary function;
- a secondary reflector that is used for a secondary function;
- a plurality of light sources, a portion of which are coincident with a focus, some of the plurality of light sources project light to the primary reflector from which a focused line is formed;
- and
- a lens, with a first end and a second end, that transmits light from the focused line that is configured to form a beam using at least one cut-off for the primary function, with the lens further configured to function as a waveguide from the first end to the second end for the secondary function;
- wherein others of the plurality of light sources project light into the first end to propagate light through the lens, with the propagated light existing the second end to project light onto the secondary reflector for the secondary function.
