Abstract
A light emitting diode, a reflector and a platform are employed within a light source. The light emitting diode emits light exclusively from its side surfaces. The reflector has a parabolic reflective surface that collimates any portion of the light reflecting from the parabolic reflective surface. The platform supports a centering of the light emitting layer(s) of the light emitting diode on a focus point of the parabolic reflective surface.
Claims19
A light source, comprising:
- a light emitting diode having one or more side surfaces, said light emitting diode operable to emit light exclusively from at least one of said one or more side surfaces;
- a reflector having a parabolic reflective surface operable to collimate any portion of the light reflecting from said parabolic reflective surface;
- and
- a platform connected to said parabolic reflective surface, said platform for supporting said light emitting diode.
