Abstract

A reflector assembly for a solid-state luminaire is disclosed. The disclosed reflector assembly may be configured, in accordance with some embodiments, to be disposed over a given printed circuit board (PCB) of a host luminaire such that emissions of emitters populated over that PCB are reflected out of the luminaire via the reflector assembly. In some embodiments, the reflector assembly may be formed from one or more reflective members, which may be generally bar-shaped or cup-shaped, or other example configurations. In some other embodiments, the reflector assembly may be formed from a bulk body having one or more reflective cavities formed therein. The particular configuration of a given reflective member or reflective cavity, as the case may be, of the reflector assembly, as well as the particular arrangement thereof for a host luminaire, may be customized as desired for a given target application or end-use.

First claim

What is claimed is:

1. A solid-state luminaire comprising:
a housing;
a printed circuit board (PCB) disposed within the housing, wherein the PCB is a single, monolithic, planar section;
a plurality of solid-state emitters populated over the PCB; and
a reflector assembly disposed within the housing and comprising a plurality of reflectors disposed over the PCB such that at least one of the solid-state emitters at least partially resides within at least one of the reflectors, wherein:
the reflector assembly is configured to direct emissions of the at least one of the solid-state emitters out of the housing;
the reflector assembly is configured such that at least one of its constituent reflectors differs in orientation from at least one other of the constituent reflectors in a single direction or multiple directions;
the reflector assembly is a single, monolithic, planar section; and
each of the plurality of reflectors is formed from the reflector assembly and traverses the full thickness of the reflector assembly.

2. The solid-state luminaire of claim 1 , wherein a first reflector in the plurality of reflectors comprises one of a parabolic reflector, a spun reflector, an elliptical reflector, a cone reflector, and a freeform reflector.

3. The solid-state luminaire of claim 1 , wherein the reflector assembly is configured such that emissions of the at least one of the solid-state emitters reflect from a reflective surface of the at least one of the reflectors, the reflective surface at least partially provided by a reflective layer disposed over at least a portion of a topography of the at least one reflector.

4. The solid-state luminaire of claim 1 , wherein the PCB and the reflector assembly are parallel to each other.

5. The solid-state luminaire of claim 1 , wherein the reflector assembly is configured such that optical axes of the plurality of reflectors converge.

6. The solid-state luminaire of claim 1 , wherein the reflector assembly is configured such that optical axes of the plurality of reflectors diverge.

7. The solid-state luminaire of claim 1 , wherein:
a first reflector in the plurality of reflectors directs emissions from a first solid-state emitter in the plurality of solid-state emitters to emit a first beam;
a second reflector in the plurality of reflectors directs emissions from a second solid-state emitter in the plurality of solid-state emitters to satisfy a second beam; and
one or more beam properties of the first beam are different than the one or more beam properties of the second beam.

8. The solid-state luminaire of claim 7 , wherein the one or more beam properties comprise at least one of a beam location, a beam orientation, a beam angle, an intensity distribution, and a color.

9. The solid-state luminaire of claim 1 , wherein the plurality of reflectors comprises at least one reflective member.

10. The solid-state luminaire of claim 1 , wherein the plurality of reflectors comprises at least one reflective cavity.
