Luminaire with rear-mounted sensing assembly
A luminaire with various sensing capabilities is provided. According to one aspect, the luminaire may include a housing and a lens covering an opening formed in the housing. In addition, the luminaire may include a sensing assembly which is disposed in the housing and configured to detect changes in an environment outside the housing. A light source may also be disposed in the housing and configured to emit light in a forward direction toward the lens. The sensing assembly may be positioned rearward of at least a portion of the light source.

a light source disposed in the housing and configured to emit light in a forward direction toward the lens, wherein the sensing assembly is positioned rearward of at least a portion of the light source.
2. The luminaire of claim 1 , the light source including a circuit board and a plurality of light emitting diodes (LEDs) mounted on the circuit board.
3. The luminaire of claim 2 , the circuit board including a non-conductive substrate and a plurality of conductive elements for supplying electricity to the LEDs.
4. The luminaire of claim 3 , at least a portion of the sensing assembly being positioned rearward of and aligned with a metal-free region of the circuit board.
5. The luminaire of claim 4 , the metal-free region of the circuit board being defined by an opening formed in the non-conductive substrate.
6. The luminaire of claim 4 , the metal-free region of the circuit board being defined by a portion of the circuit board that is free of any of the plurality of conductive elements.
7. The luminaire of claim 6 , an area covered by the metal-free region of the circuit board when viewed in a plan view is greater than or equal to 0.5 square inches.
8. The luminaire of claim 4 , the sensing assembly including a sensor configured to detect motion within a pre-determined distance from the luminaire.
9. The luminaire of claim 2 , comprising a light pipe member disposed in the housing and configured to transport ambient light rays present in the environment to the sensing assembly, the light pipe member having a light entry end disposed forward of the circuit board and a second end disposed rearward of the circuit board, at least a portion of the sensing assembly being positioned to receive the ambient light rays from or within the second end of the light pipe member.
10. The luminaire of claim 9 , the light entry end of light pipe member extending at least partially through an opening formed in the lens.
11. The luminaire of claim 9 , the light pipe member including a hollow cylinder.
12. The luminaire of claim 9 , the sensing assembly including a sensor configured to detect an intensity of the ambient light rays.
13. A luminaire comprising:
a housing;
a lens covering an opening formed in the housing; and
a light source including a circuit board disposed in the housing and being configured to emit light toward the lens, wherein the circuit board includes a metal-free region.
14. The luminaire of claim 13 , wherein an area covered by the metal-free region of the circuit board when viewed in a plan view is greater than or equal to 0.5 square inches.
15. The luminaire of claim 14 , the metal-free region of the circuit board being defined by an opening formed in the non-conductive substrate.
