Abstract

A trim for a lighting fixture includes a trim structure, a processor disposed on the trim structure, and an interface electrically coupled to the processor. A power is provided to the processor from a power source of the lighting fixture via the interface.

First claim

What is claimed is:

1. A trim for a lighting fixture, the trim comprising:
a trim structure;
a printed circuit board that is disposed on a back side of the trim structure hidden from view when the lighting fixture is installed, wherein a processor is attached to the printed circuit board, wherein one or more sensors are attached to and positioned on a side of the printed circuit board facing the back side of the trim structure and communicably coupled to the processor, and wherein a front side of the trim structure is at least partially viewable from below the lighting fixture when the lighting fixture is installed; and
an interface electrically coupled to the processor, wherein a power is provided to the processor from a power source of the lighting fixture via the interface.

2. The trim of claim 1 , wherein the interface provides a communication interface for the processor to send one or more electrical signals.

3. The trim of claim 1 , wherein the printed circuit board includes a curved perimeter edge to conform to a ring-shape of the trim structure.

4. The trim of claim 1 , wherein the one or more sensors are positioned at least partially over one or more holes in the trim structure.

5. The trim of claim 1 , further comprising one or more microphones disposed on the trim structure and electrically coupled to the processor.

6. The trim of claim 1 , further comprising a transceiver for transmitting and receiving wireless signals in compliance with one or more wireless communication standards.

7. The trim of claim 1 , further comprising one or more indicator light sources disposed on the trim structure, wherein the one or more indicator light sources are positioned to emit one or more lights through one or more holes in the trim structure.

8. The trim of claim 1 , further comprising a switch that is configurable during manufacturing or installation to indicate to a lighting driver of the lighting fixture a desired correlated color temperature of a light emitted by a light source of the lighting fixture when the trim is attached to the lighting fixture.

9. The trim of claim 1 , wherein the printed circuit board is at least partially outside of a housing of the lighting fixture when the trim is attached to the housing.

10. The trim of claim 1 , further comprising a baffle extending up from the trim structure on the back side of the trim structure.

11. A lighting fixture, comprising:
a housing;
a light source disposed in the housing; and
a trim detachably attached to the housing, the trim comprising:
a trim structure;
a printed circuit board that is disposed on a back side of the trim structure hidden from view when the lighting fixture is installed, wherein a processor is attached to the printed circuit board, wherein one or more sensors are attached to and positioned on a side of the printed circuit board facing the back side of the trim structure and communicably coupled to the processor, and wherein a front side of the trim structure is at least partially viewable from below the lighting fixture when the lighting fixture is installed; and
an interface electrically coupled to the processor, wherein a power is provided to the processor via the interface.

12. The lighting fixture of claim 11 , further comprising a driver that provides the power for the processor and a second power to the light source.

13. The lighting fixture of claim 12 , wherein the processor is configured to provide one or more lighting control signals to the driver via the interface to control a light emitted by the light source.

14. The lighting fixture of claim 11 , further comprising one or more microphones and a transceiver, wherein the transceiver is configured to transmit and receive wireless signals in compliance with one or more wireless communication standards and wherein the processor is configured to process a voice command received by the one or more microphones to produce a processed voice command and to transmit the processed voice command via the transceiver.

15. The lighting fixture of claim 11 , further comprising one or more sensors disposed on the trim structure and communicably coupled to the processor, wherein the one or more sensors are positioned at least partially over one or more holes in the trim structure.

16. The lighting fixture of claim 11 , wherein the one or more sensors are mounted on the printed circuit board that is attached to the trim structure on the back side of the trim.

17. The lighting fixture of claim 11 , further comprising an integrated projector positioned to project an image using a light emitted by the light source.

18. The lighting fixture of claim 11 , further comprising a driver and a power module, wherein the driver is coupled to provide a second power to the light source and the power module is coupled to provide the power to the processor.

19. A lighting fixture, comprising:
a housing;
a light source disposed in the housing;
a base trim attached to the housing; and
a smart trim detachably attached to the base trim and covering the base trim from below the lighting fixture, the smart trim comprising:
a trim structure;
a printed circuit board that is disposed on a back side of the trim structure hidden from view when the lighting fixture is installed, wherein a processor is attached to the printed circuit board, wherein one or more sensors are attached to and positioned on a side of the printed circuit board facing the back side of the trim structure and communicably coupled to the processor, and wherein a front side of the trim structure is at least partially viewable from below the lighting fixture when the lighting fixture is installed; and
an interface electrically coupled to the processor, wherein a power is provided to the processor via the interface.

20. The lighting fixture of claim 19 , further comprising a driver that provides the power for the processor and a second power to the light source.
