Abstract
A lighting fixture employs one or more reverse parabolic reflectors and molded lenses in a faceplate to provide a variety of light output intensities and emission patterns. Some embodiments clip the reverse parabolic reflectors to fit within the outline of the faceplate without sacrificing significant light output.
Claims19
A lighting fixture comprising:
- a light transmissive faceplate having a perimeter;
- at least one molded lens molded into the faceplate;
- at least one clipped reverse parabolic reflector, each clipped reverse parabolic reflector having a defined area;
- the faceplate further defining at least one location for the at least one clipped reverse parabolic reflector;
- and
- a light emitter, centered in each lens and in each clipped reverse parabolic reflector.
3 more elements
A lighting fixture comprising:
- a faceplate, the faceplate having a closed perimeter and a planar face;
- a plurality of molded lenses molded into the faceplate within the perimeter of the faceplate;
- a plurality of clipped reverse parabolic reflectors, each of the clipped reverse parabolic reflectors having a defined planar area, the clipped parabolic reflectors further adapted to emit light along an axis perpendicular to the defined planar area;
- the faceplate further defining a plurality of locations for the plurality of clipped reverse parabolic reflectors;
- and
- a plurality of light emitters, at least one light emitter centered in each lens and in each clipped reverse parabolic reflector.

A method of building a lighting fixture, the method comprising:
- selecting a faceplate, the faceplate having a perimeter;
- determining light output and pattern requirements of lighting fixture;
- selecting a combination of reverse parabolic reflectors and lenses to meet light output and light pattern requirements;
- molding a plurality of lenses into the faceplate;
- selectively clipping the edges on at least one reverse parabolic reflector to form at least one clipped reverse parabolic reflector;
- molding a location in the faceplate for at least one clipped parabolic reflector, the location adapted to constrain the clipped parabolic reflector;
- and
- placing an LED in the center of each clipped parabolic reflectors and each of the plurality of lenses.
