Abstract

A luminaire includes a housing defining an interior volume. The luminaire also includes a lamp within the interior volume and configured to emit light. Additionally, the luminaire includes a wireless antenna positioned within the interior volume, configured to transmit or receive a wireless signal along a first direction, and configured to be operatively coupled to an access point. The wireless antenna can be entirely within the interior volume. The luminaire can include a first reflective surface within the interior volume and configured to redirect the wireless signal. The lamp can be configured to be electrically coupled to a power inserter that powers the access point.

First claim

What is claimed is:

1. A luminaire comprising:
a housing defining an interior volume of the luminaire;
a lamp within the interior volume and configured to emit light;
a first wireless antenna positioned within the interior volume, configured to receive a wireless signal from a computational device, wherein the first wireless antenna is coupled to an access point via a cable; and
a reflector assembly positioned within the interior volume between the first wireless antenna and the lamp, wherein the reflector assembly is a heat sink.

2. The luminaire of claim 1 , wherein the first wireless antenna is positioned entirely within the interior volume.

3. The luminaire of claim 1 , wherein the housing further comprises a transparent or translucent surface, and wherein the lamp and the first wireless antenna are positioned such that the emitted light and the wireless signal pass through the transparent or translucent surface.

4. The luminaire of claim 1 , wherein:
the first wireless antenna is configured to transmit a second wireless signal to the computational device; and
the access point is configured to couple the computational device to a network.

5. The luminaire of claim 1 , wherein the first wireless antenna is a directional antenna.

6. The luminaire of claim 1 , wherein the first wireless antenna is an omnidirectional antenna or a dipole antenna.

7. The luminaire of claim 1 , wherein the lamp is an LED lamp.

8. A luminaire comprising:
a housing defining an interior volume of the luminaire;
a lamp within the interior volume; and
a plurality of wireless antennas positioned within the interior volume and circumferentially around a center of the housing, and configured to receive wireless signals, wherein a first wireless antenna of the plurality of wireless antennas is coupled to an access point via a cable; and
a cylindrical reflector configured to shield wireless signals corresponding to the plurality of wireless antennas from each other, wherein the lamp, the center of the housing, and the cylindrical reflector are coaxial.

9. The luminaire of claim 8 , wherein the plurality of wireless antennas are equally spaced apart around the center of the housing.

10. The luminaire of claim 8 , wherein the plurality of wireless antennas are positioned entirely within the interior volume.

11. The luminaire of claim 8 , wherein the housing further comprises a transparent or translucent surface, and wherein the lamp and the plurality of wireless antennas are positioned such that emitted light from the lamp and the wireless signals pass through the transparent or translucent surface.

12. The luminaire of claim 8 , wherein:
the first wireless antenna is configured to transmit a second wireless signal to a computational device; and
the access point is configured to couple the computational device to a network.

13. The luminaire of claim 8 , wherein the first wireless antenna is a directional antenna.

14. The luminaire of claim 8 , wherein the first wireless antenna is an omnidirectional antenna or a dipole antenna.

15. The luminaire of claim 8 , wherein the lamp is an LED lamp.

16. A luminaire comprising:
a housing defining an interior volume of the luminaire;
a lamp within the interior volume; and
a plurality of wireless antennas positioned within the interior volume and circumferentially around a center of the housing, and configured to receive wireless signals, wherein a first wireless antenna of the plurality of wireless antennas is coupled to an access point via a cable;
a reflector assembly positioned within the interior volume between the first wireless antenna and the lamp, wherein the reflector assembly is a heat sink; and
the reflector assembly comprises a cylindrical reflector configured to shield wireless signals corresponding to the plurality of wireless antennas from each other, wherein the lamp, the reflector assembly, and the cylindrical reflector are coaxial.

17. The luminaire of claim 16 , wherein the housing further comprises a transparent or translucent surface, and wherein the lamp and the first wireless antenna are positioned such that emitted light from the lamp and the wireless signal pass through the transparent or translucent surface.

18. The luminaire of claim 16 , wherein:
the first wireless antenna is configured to transmit a second wireless signal to a computational device; and
the access point is configured to couple the computational device to a network.

19. The luminaire of claim 16 , wherein the first wireless antenna is a directional antenna, an omnidirectional antenna, or a dipole antenna.
