Abstract

A luminaire to be carried by a lighting fixture. The luminaire may include a housing, a primary optic disposed within the housing having a reflective inner surface defining an optical chamber, a light source, and a heat sink defining an aperture through which light may propagate. The light source may include a plurality of light-emitting diodes (LEDs). The luminaire may further include a secondary optic positioned adjacent to the light source that may collimate and/or refract light emitted by the light source, and may form a seal between the light source and the optical chamber. The luminaire may further include a color conversion layer configured to change the color of light emitted by the light source.

Claims (23)

1. A luminaire adapted to be carried by a light fixture comprising:

a housing;

a primary optic disposed within the housing having a reflective inner surface and a generally elongated shape defining an optical chamber and an aperture;

a light source;

a heat sink;

a secondary optic positioned adjacent to the light source; and

a plurality of hanger holes;

wherein the light source is positioned in thermal communication with the heat sink;

wherein light emitted by the light source enters the optical chamber incident upon the reflective inner surface of the primary optic, and is reflected through the aperture;

wherein the secondary optic is configured to attach to the heat sink and form a seal between the light source and the optical chamber;

wherein the primary optic further comprises an attachment structure positioned on the outer surface of the primary optic; and

wherein each of the plurality of hanger holes is configured to attach to an external light fixture.

2. A luminaire according to claim 1 further comprising an occupancy sensor having a field of view;

wherein the controller is in communication with the occupancy sensor;

wherein the occupancy sensor is configured to determine whether an object is within the field of view of the occupancy sensor;

wherein the occupancy sensor is configured to transmit a positive indication when an object is determined to be within the field of view; and

wherein the controller is configured to operate the light source to illuminate the field of view of the occupancy sensor upon receiving the positive indication.

3. A luminaire according to claim 2 wherein the occupancy sensor is configured to determine the position of the object along the length of the luminaire; and wherein the controller is configured to operate the plurality of LEDs adjacent to the same position as the object along the length of the luminaire.

4. A luminaire according to claim 1 further comprising a network interface configured to enable communication with a network;

wherein the controller is in communication with the network interface;

wherein the network interface is operable to receive communications across the network and provide an instruction to the controller; and

wherein the controller operates the light source responsive to the instruction received from the network interface.

5. A luminaire according to claim 4 wherein the network comprises a plurality of luminaires; wherein the controller is operable to send an instruction to the network interface; and wherein the network interface is operable to transmit the instruction to each of the plurality of luminaires across the network.
