Abstract

An apparatus including a polymeric housing to enclose electrical and optical components of a lighting fixture; and an outer frame affixed to the housing, the outer frame including a coupler to mechanically attach the apparatus to another device.

Claims

1. A lighting apparatus comprising:

a polymeric housing enclosing electrical and optical components of a lighting fixture, the polymeric housing comprising a plastic upper housing and a plastic cover plate including a peripheral sidewall that matingly cooperates with the upper housing to provide a cavity for housing the electrical and optical components therein,

wherein the optical components comprise a plurality of optical lenses, wherein the plurality of optical lenses comprise at least one optical lens configured to distribute light emitted from a solid state light source in a predetermined pattern; and

an outer frame matingly fit on top of the upper housing of the polymeric housing, the outer frame including a coupler to mechanically attach the lighting apparatus to another device, wherein the outer frame is constructed of at least one of metal, a metal alloy, and a composite material,

the outer frame further comprising a central spine bridging and connecting opposing sides of the upper housing in a lengthwise fashion.

2. The lighting apparatus of claim 1, wherein the coupler includes an open distal end to receive a mounting device therein.

3. The lighting apparatus of claim 1, wherein the polymeric housing is constructed of at least one of a polycarbonate, PMMA (poly methylmethacrylate), PC (polycarbonate), and combinations thereof.

4. The lighting apparatus of claim 1, wherein the outer frame facilitates an electrical connection with a source of communication signals.

5. The lighting apparatus of claim 1, wherein the electrical components comprise a printed circuit board and the solid state light source.

6. The lighting apparatus of claim 5, wherein the solid state light source includes at least one light emitting diode (LED) supported by the printed circuit board.

7. A lighting fixture comprising:

a circuit board;

a solid state light source supported on the circuit board;

a plurality of optical lenses, wherein the plurality of optical lenses comprise at least one optical lens affixed or joined to the circuit board to distribute light emitted from the solid state light source;

a polymeric housing comprising a plastic upper housing and a plastic cover plate including a peripheral sidewall that matingly cooperates with the upper housing to provide a cavity that encloses the circuit board, the solid state light source, and the plurality of optical lenses, wherein the at least one optical lens is configured to distribute light emitted from the solid state light source within the polymeric housing in a predetermined pattern; and

an outer frame matingly fit on top of the upper housing of the polymeric housing, the outer frame being constructed of at least one of metal, a metal alloy, and a composite material, the outer frame further comprising a central spine bridging and connecting opposing sides of the upper housing in a lengthwise fashion.

8. The lighting fixture of claim 7, further comprising a breather in the polymeric housing to facilitate draining of moisture from the polymeric housing.

9. The light fixture of claim 8, wherein the breather further facilitates equalizing a pressure inside and outside of the polymeric housing.

10. A lighting fixture comprising:

a circuit board;

a solid state light source supported on the circuit board;

a plurality of optical lenses, wherein the plurality of optical lenses comprise at least one optical lens affixed or joined to the circuit board to distribute light emitted from the solid state light source;

a polymeric housing comprising a plastic upper housing and a plastic cover plate including a peripheral sidewall that matingly cooperates with the upper housing to provide a cavity that encloses the circuit board, the solid state light source, and the plurality of optical lenses, wherein the at least one optical lens is configured to distribute light emitted from the solid state light source within the polymeric housing in a predetermined pattern; and

an outer frame matingly fit on top of the upper housing of the polymeric housing, the outer frame being constructed of at least one of metal, a metal alloy, and a composite material, the outer frame further comprising a central spine bridging and connecting opposing sides of the upper housing in a lengthwise fashion;

wherein the outer frame facilitates an electrical connection with a source of communication signals.
