Abstract

A compact recessed lighting system is provided. The lighting system includes a light source module, a heat sink, a lens, a set of electrical contacts, and a set of trims. Each of these elements of the lighting system may be coupled to an integrated interface module. The recessed lighting system provides a reduced set of components while ensuring adaptability and easy installation into a structure. In particular, by including an integrated interface module that allows the light source module, the set of trims, the lens, and the heat sink to be easily replaced with minimal tools and minimal fasteners, the recessed lighting system described herein provides a more efficient and user friendly design in comparison to traditional systems.

First claim

What is claimed is:

1. A compact recessed lighting system, comprising:
a light source module for emitting light;
a set of electrical contacts for contacting electrical leads on the light source module to provide electricity from a power source to the light source module; and
an integrated interface module for supporting the set of electrical contacts and the light source module, wherein the electrical contacts are coupled to the integrated interface module such that the electrical contacts apply pressure to the electrical leads of the light source module.

2. The compact recessed lighting system of claim 1 , wherein each of the electrical contacts in the set of electrical contacts comprises:
a base end for coupling to the integrated interface module; and
a finger for applying pressure to the electrical leads of the light source module, wherein the electrical contacts pass electricity from the power source to the light source module via the electrical leads to power the light source module to emit light.

3. The compact recessed lighting system of claim 2 , wherein the integrated interface module comprises:
a set of fastener blocks for receiving corresponding base ends of separate electrical contacts from the set of electrical contacts and coupling the electrical contacts to the integrated interface module; and
a set of guides for supporting corresponding fingers of separate electrical contacts from the set of electrical contacts and ensuring the fingers remain in contact with the electrical leads of the light source module.

4. The compact recessed lighting system of claim 1 , wherein the integrated interface module comprises:
mounting blocks for supporting the light source module using a set of fasteners.

5. The compact recessed lighting system of claim 4 , further comprising:
a heat sink for dissipating heat generated by the light source module, wherein the light source module and the heat sink are jointly coupled to the integrated interface module using the mounting blocks and the set of fasteners such that the light source module is sandwiched between the integrated interface module and the heat sink.

6. The compact recessed lighting system of claim 1 , further comprising:
a lens for adjusting light emitted by the light source module.

7. The compact recessed lighting system of claim 6 , wherein the integrated interface module comprises:
a lip for receiving the lens, wherein the lip is sized such that the lens maintains a pressure fit connection with the integrated interface module.

8. The compact recessed lighting system of claim 7 , wherein the integrated interface module is defined by a frusto conical shape that includes:
an open front face;
an open rear face; and
a set of walls connecting the open front face and the open rear face and creating a cavity between the open front face and the open rear face, wherein the light source module is coupled to the open rear face such that light from the light source module is emitted through the cavity and through the open front face.

9. The compact recessed lighting system of claim 8 , further comprising:
a reflector insert that is inserted inside the cavity of the integrated interface module, wherein the reflector insert includes 1) an upper opening shaped to at least partially surround the light source module and 2) a lower opening shaped to meet the dimensions of an upper opening of a trim.

10. The compact recessed lighting system of claim 8 , wherein the integrated interface module comprises:
a channel for receiving a trim, wherein the channel is defined by a set of concentric walls surrounding the open front face.

11. The compact recessed lighting system of claim 10 , further comprising:
one or more trims for focusing light emitted by the light source module and hiding a hole in which the compact recessed lighting system is installed, wherein the trim includes 1) an upper opening surrounded by a ridge for coupling with the channel of the integrated interface module and 2) a lower opening surrounded by a flange for hiding the hole in which the compact recessed lighting system is installed.

12. The compact recessed lighting system of claim 11 , wherein the ridge of each of the one or more trims is sized to fit within the channel to create a friction connection between the ridge and the walls of the channel.

13. A compact recessed lighting system, comprising:
a light source module for emitting light;
an integral optical chamber to direct light emitted from the light source module into a room; and
a channel for receiving a trim, wherein the channel is defined by a set of concentric walls and the channel is sized to meet the dimensions of a ridge connector surrounding an opening of the trim such that the ridge connector and the channel create a snap connection when the ridge connector is forced inside the channel.

14. The compact recessed lighting system of claim 13 , wherein the integral optical chamber comprises:
an open front face,
an open rear face, and
a set of walls connecting the open front face and the open rear face and creating a cavity between the open front face and the open rear face, wherein 1) the channel is located along the open front face to couple the trim to the open front face and 2) the light source module is coupled to the open rear face such that light from the light source module is emitted through the cavity, through the open front face, and through the trim and into the room.

15. The compact recessed lighting system of claim 14 , wherein the integral optical chamber further comprises:
mounting blocks located along the open rear face of the integral optical chamber for supporting the light source module using a set of fasteners.

16. The compact recessed lighting system of claim 14 , wherein the integral optical chamber further comprises:
a set of reflecting elements located on the set of walls that assist in the adjustment of light emitted by the light source module.

17. A compact recessed lighting system, comprising:
a light source module for emitting light;
an integrated interface module defining a cavity to direct light emitted from the light source module; and
a reflector insert that is inserted inside the cavity of the integrated interface module, wherein the reflector insert includes 1) an upper opening shaped to at least partially surround the light source module and 2) a lower opening shaped to meet the dimensions of an upper opening of a trim.

18. The compact recessed lighting system of claim 17 , further comprising:
a lens for adjusting light emitted by the light source module, wherein the integrated interface module includes a lip for receiving the lens and the lip is sized such that the lens maintains a pressure fit connection with the integrated interface module and secures the reflector insert within the cavity of the integrated interface module.

19. The compact recessed lighting system of claim 17 , wherein the integrated interface module further includes:
a set of reflecting elements located on walls of the integrated interface module that assist in the adjustment of light emitted by the light source module.

20. The compact recessed lighting system of claim 17 , further comprising:
a heat sink for dissipating heat generated by the light source module, wherein the light source module and the heat sink are jointly coupled to the integrated interface module such that the light source module is sandwiched between the integrated interface module and the heat sink.
