Abstract

A luminaire can include a housing having at least one outer surface that forms a cavity. The luminaire can also include an aperture that traverses the at least one outer surface of the housing. The luminaire can further include a substrate disposed within the cavity. The luminaire can also include an electrical connector disposed on the substrate adjacent to the aperture. The luminaire can further include a dial coupled to the electrical connector, where dial has a range of positions, where each position within the range of positions of the dial corresponds to a discrete correlated color temperature (CCT) output by multiple light sources of the luminaire.

First claim

What is claimed is:

1. A luminaire comprising:
a housing comprising at least one outer surface that forms a cavity;
an aperture that traverses the at least one outer surface of the housing;
a substrate disposed within the cavity;
an electrical connector disposed on the substrate adjacent to the aperture; and
a dial coupled to the electrical connector, wherein dial has a range of positions, wherein each position within the range of positions of the dial corresponds to a discrete correlated color temperature (CCT) output by a plurality of light sources of the luminaire.

2. The luminaire of claim 1 , wherein the dial is a single component.

3. The luminaire of claim 2 , wherein each position of the range of positions is discrete.

4. The luminaire of claim 3 , wherein the range of positions of the dial comprises a first position, a second position, a third position, a fourth position, and a fifth position.

5. The luminaire of claim 4 , wherein the first position of the dial corresponds to 2700 Kelvin (K) output by the plurality of light sources, wherein the second position of the dial corresponds to 3000 K output by the plurality of light sources, wherein the third position of the dial corresponds to 3500 K output by the plurality of light sources, wherein the fourth position of the dial corresponds to 4000 K output by the plurality of light sources, and wherein the fifth position of the dial corresponds to 5000 K output by the plurality of light sources.

6. The luminaire of claim 1 , wherein the dial is removably coupled to the electrical connector.

7. The luminaire of claim 6 , further comprising:
a removable plug disposed in the aperture that traverses the at least one outer surface of the housing when the dial is decoupled from the electrical connector.

8. The luminaire of claim 7 , wherein the removable plug and the dial are removable by a user without tools.

9. The luminaire of claim 1 , wherein the aperture traverses a top outer surface of the housing.

10. The luminaire of claim 1 , wherein the dial is coupled to the electrical connector during installation of the luminaire.

11. The luminaire of claim 1 , wherein the dial is inaccessible when the luminaire is installed.

12. The luminaire of claim 1 , wherein the dial comprises an actuator, wherein the actuator of the dial is disposed outside the cavity.

13. A dial for controlling a correlated color temperature (CCT) of light emitted by a luminaire, the dial comprising:
a body;
at least one first coupling feature disposed on a bottom end of the body, wherein the at least one first coupling feature is configured to electrically couple to an electrical connector of the luminaire; and
an actuator disposed on the body, wherein the actuator has a range of positions and rotates relative to the body,
wherein each position of the range of positions of the actuator corresponds to a CCT of the light emitted by the luminaire.

14. The dial of claim 13 , wherein each position is continuous within the range of positions.

15. The dial of claim 13 , wherein each position is discrete within the range of positions.

16. The dial of claim 15 , wherein the range of positions comprises a first position, a second position, a third position, a fourth position, and a fifth position.

17. The dial of claim 13 , further comprising:
at least one second coupling feature disposed adjacent to the at least one first coupling feature, wherein the at least one second coupling feature is configured to align the at least one first coupling feature relative to the electrical connector of the luminaire.

18. A luminaire comprising:
a housing comprising at least one outer surface that forms a cavity;
a plurality of light sources;
an aperture that traverses the at least one outer surface of the housing;
a substrate disposed within the cavity; and
an electrical connector disposed on the substrate adjacent to the aperture, wherein the electrical connector is configured to couple to a dial, wherein the dial has a range of positions, wherein each position within the range of positions of the dial corresponds to a discrete correlated color temperature (CCT) output by the plurality of light sources.

19. The luminaire of claim 18 , further comprising:
a removable plug removably disposed in the aperture that traverses the at least one outer surface of the housing.

20. The luminaire of claim 18 , wherein the electrical connector is located relative to the aperture such that the dial, when coupled to the electrical connector, is disposed outside the cavity.
