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.

Claims

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; and

a dial electrically coupled to the electrical connector, 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 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 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; and

a switch electrically coupled to the electrical connector, wherein the switch has multiple positions, wherein each position of the switch corresponds to a discrete correlated color temperature (CCT) output by a plurality of light sources of the luminaire.

14. The luminaire of claim 13, wherein the switch is a single component.

15. The luminaire of claim 14, wherein the switch is a slide switch.

16. The luminaire of claim 15, wherein the switch has a first position, a second position, a third position, a fourth position, and a fifth position.

17. The luminaire of claim 13, wherein the switch is removably coupled to the electrical connector.

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, 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.
