Abstract

A luminaire can include a housing having at least one outer surface that forms a cavity. The luminaire can also include at least one electrical component disposed, at least in part, within the cavity. The luminaire can further include an electrical cable having a first end and a second end, where the first end is coupled to the at least one electrical component. The luminaire can also include a switch coupled to the electrical cable, where the switch is disposed remotely from the housing, where the switch has multiple positions, wherein each position of the switch corresponds to a discrete correlated color temperature (CCT) output by one or more light sources of the luminaire.

Claims

1. A luminaire comprising:

a housing comprising at least one outer surface that forms a first cavity;

at least one electrical component disposed, at least in part, within the first cavity;

an electrical cable comprising a first end and a second end, wherein the first end is coupled to the at least one electrical component; and

a switch coupled to the electrical cable, wherein the switch is disposed remotely from the housing, wherein the switch has a plurality of positions, wherein each position of the plurality of positions of the switch corresponds to a discrete correlated color temperature (CCT) output by one or more light sources of the luminaire.

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

3. The luminaire of claim 1, wherein each position of the plurality of positions is discrete.

4. The luminaire of claim 3, wherein the plurality of positions of the switch 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 switch corresponds to 2700 Kelvin (K) output by the one or more light sources, wherein the second position of the switch corresponds to 3000 K output by the one or more light sources, wherein the third position of the switch corresponds to 3500 K output by the one or more light sources, wherein the fourth position of the switch corresponds to 4000 K output by the one or more light sources, and wherein the fifth position of the switch corresponds to 5000 K output by the one or more light sources.

6. The luminaire of claim 1, wherein the switch is integrated with the electrical cable.

7. The luminaire of claim 1, further comprising:

a junction box comprising at least one wall that forms a second cavity, wherein the switch is disposed within the second cavity, wherein the second end of the electrical cable is coupled to the switch.

8. The luminaire of claim 1, further comprising:

a junction box comprising at least one wall that forms a second cavity, wherein the second cavity has disposed therein at least one additional electrical component; and

an additional electrical cable,

wherein the switch is coupled to the second end of the electrical cable, wherein the additional electrical cable is coupled to the switch and to the at least one additional electrical component,

wherein the switch is disposed outside the second cavity.

9. The luminaire of claim 1, wherein the switch is a slide switch.

10. The luminaire of claim 1, wherein the switch is a rotary switch.

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

12. The luminaire of claim 1, wherein the switch is accessible to a user when the housing is removed from its installed location.

13. A switch for controlling a correlated color temperature (CCT) of light emitted by a luminaire, the switch comprising:

a body;

at least one first coupling feature disposed on the body, wherein the at least one first coupling feature is configured to electrically couple to an electrical cable of the luminaire; and

an actuator disposed on the body, wherein the actuator has a range of positions,

wherein each position of the range of positions of the actuator corresponds to a CCT of the light emitted by the luminaire.

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

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

16. The switch 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 switch 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 electrically couple to an additional electrical cable of the luminaire.

18. The switch of claim 13, wherein the body is configured to be integrated with the electrical cable.

19. The switch of claim 13, wherein the body is configured to be disposed within a junction box.

20. The switch of claim 13, wherein the switch is a rotary switch.
