Abstract

A resulting light fixture can include a base light fixture having at least one light source and at least one first coupling feature, where the first coupling feature is configured to detachably couple to a second coupling feature of a power source. The resulting light fixture can further include an in-line adapter having at least one light fixture component, a third coupling feature, and a fourth coupling feature, where the third coupling feature is detachably coupled to the first coupling feature of the base light fixture, where the fourth coupling feature is configured to detachably couple to the second coupling feature of the power source, and where the at least one light fixture component provides a capability absent in the base light fixture.

First claim

What is claimed is:

1. A resulting light fixture, comprising:
a base light fixture comprising at least one light source and a first coupling feature, wherein the first coupling feature is configured to detachably couple to a second coupling feature of a power source; and
an in-line adapter comprising at least one light fixture component, a third coupling feature, and a fourth coupling feature, wherein the third coupling feature is detachably coupled to the first coupling feature of the base light fixture, wherein the fourth coupling feature is configured to detachably couple to the second coupling feature of the power source, wherein the at least one light fixture component provides a capability absent in the base light fixture, and wherein the second coupling feature of the power source and the first coupling feature of the base light fixture are configured to couple directly to each other in the absence of the in-line adapter.

2. The resulting light fixture of claim 1 , wherein at least one light fixture component comprises a transceiver that communicates using wireless communication.

3. The resulting light fixture of claim 2 , wherein the at least one light fixture component further comprises at least one antenna for transmitting and receiving wireless signals.

4. The resulting light fixture of claim 1 , wherein the at least one light fixture component comprises a sensor device that measures one or more parameters that are used outside of operating the at least one light source.

5. The resulting light fixture of claim 1 , wherein the at least one light fixture component comprises a sensor device that measures one or more parameters that are used to operate the at least one light source.

6. The resulting light fixture of claim 1 , wherein the at least one light fixture component comprises a switch.

7. The resulting light fixture of claim 6 , wherein the switch is used to select a setting associated with light emitted by the at least one light source.

8. The resulting light fixture of claim 1 , wherein the at least one light fixture component comprises a control engine configured to control the at least one light source.

9. The resulting light fixture of claim 1 , wherein the in-line adapter is disposed within a housing of the base light fixture.

10. The resulting light fixture of claim 1 , wherein the in-line adapter is disposed outside of the housing of the base light fixture.

11. The resulting light fixture of claim 1 , wherein the base light fixture is an existing light fixture, and wherein the in-line adapter retrofits the base light fixture.

12. An in-line adapter for a light fixture, the in-line adapter comprising:
a first coupling feature configured to detachably couple to a second coupling feature of a power source that provides primary power;
a third coupling feature configured to detachably couple to a fourth coupling feature of a base light fixture portion; and
an adapter housing coupled to and disposed between the first coupling feature and the second coupling feature, wherein the adapter housing forms a cavity in which at least one light fixture component is disposed,
wherein the at least one light fixture component provides a capability absent in the base light fixture portion, and
wherein the second coupling feature and the fourth coupling feature, in the absence of the first coupling feature and the third coupling feature, are configured to detachably couple directly to each other.

13. The in-line adapter of claim 12 , wherein the first coupling feature comprises a first connector end, and wherein the second coupling feature comprises a first complementary connector end.

14. The in-line adapter of claim 13 , further comprising:
at least one electrical wire disposed between the first connector end and the adapter housing, wherein the at least one electrical wire is configured to transmit the primary power from the first connector end to the at least one light fixture component.

15. The in-line adapter of claim 12 , wherein the third coupling feature comprises a second connector end, and wherein the fourth coupling feature comprises a second complementary connector end.

16. The in-line adapter of claim 15 , further comprising:
at least one electrical wire disposed between the second connector end and the adapter housing, wherein the at least one electrical wire is configured to transmit signals from the at least one light fixture component to the second connector end.

17. The in-line adapter of claim 12 , wherein the at least one light fixture component is disposed within the adapter housing.

18. The in-line adapter of claim 12 , wherein the third coupling feature is disposed on the adapter housing.

19. A resulting light fixture, comprising:
a base light fixture comprising at least one light source and at least one first coupling feature; and
an in-line adapter comprising a dimming controller, a second coupling feature, and a third coupling feature, wherein the second coupling feature is detachably coupled to the first coupling feature of the base light fixture, wherein the third coupling feature is configured to detachably couple to a fourth coupling feature of a power source, and wherein the dimming controller provides a capability to dim the at least one light source that is absent in the base light fixture without the in-line adapter.

20. The resulting light fixture of claim 19 , wherein the dimming controller further provides the capability to turn the at least one light source on and off.
