Abstract

A light module includes a heat sink and one or more light sources coupled within a heat sink cavity formed therein. The heat sink includes an internal surface surrounding the cavity. The internal surface includes a mounting region, a reflector region extending from the perimeter of the mounting region to a distal end, and a decorative region extending from the distal end to a second distal end. The light module includes multiple mounting pads coupled circumferentially around a portion of the heat sink. The mounting pads are configured to facilitate the heat sink being coupled within different housing diameter sizes. The light module includes a trim ring integrally formed with the heat sink and extending radially outward from one end of the heat sink.

Claims

1. A light module, comprising:

a heat sink comprising an internal surface surrounding a heat sink cavity formed therein, the internal surface comprising;

a mounting region; and

a reflector region extending from the perimeter of the mounting region to a distal end;

one or more light sources coupled to the mounting region within the heat sink cavity; and

a plurality of mounting pads disposed circumferentially around a portion of the heat sink to separably couple the light module to a housing having a five inch diameter cavity or a housing having a six inch diameter cavity, each mounting pad comprising;

a first receiving hole; and

a second receiving hole,

wherein either the first receiving hole or the second receiving hole is coupled to a torsion spring,

wherein when the torsion spring is coupled to the first receiving hole, the light module is coupled to the housing having the five inch diameter cavity, and

wherein when the torsion spring is coupled to the second receiving hole, the light module is coupled to the housing having the six inch diameter cavity.

2. The light module of claim 1, wherein the reflector region is smooth.

3. The light module of claim 1, further comprising a decorative region extending from the distal end to a second distal end;

and a trim ring extending radially outward from substantially a second distal end, wherein the trim ring and the heat sink are integrally formed as a single component thereby providing continuous non-movable contact between the trim ring and the heat sink.

4. The light module of claim 1, further comprising a driver coupled to one end of the heat sink.

5. The light module of claim 1, wherein the first receiving hole and the second receiving hole are recessed openings formed within the mounting pad.

6. A light module, comprising:

a heat sink comprising an internal surface surrounding a heat sink cavity formed therein;

one or more light sources coupled to a portion of the internal surface of the heat sink cavity; and

a plurality of mounting pads disposed circumferentially around a portion of the heat sink for separably coupling the light module to a housing having a five inch diameter cavity or a housing having a six inch diameter cavity, each mounting pad comprising at least one receiving hole,

wherein each mounting pad comprises a first portion that radially extends from the heat sink and a second surface that is substantially perpendicular to the first portion, and

wherein the at least one receiving hole of each mounting pad is located on the first portion respective mounting pad;

a plurality of mounting brackets, each mounting bracket removably coupled to one of the respective mounting pads and comprising;

a first planar portion comprising a first end, a second end, a pair of longitudinal edges extending from the first end to the second end, and a slot formed between the pair of longitudinal edges and extending along a portion of the first planar portion;

a second planar portion extending substantially perpendicularly and downwardly from one of the first end and the second end and comprising a mechanism for mounting a torsion spring,

wherein at least a portion of the slot is aligned with the at least one receiving hole, the at least one receiving hole and the slot receiving a coupling device to couple the mounting bracket to the mounting pad,

wherein the light module is coupled to the housing having a five inch diameter when the mounting bracket is fastened to the mounting pad at a first position of the slot, and

wherein the light module is coupled to the housing having a six inch diameter when the mounting bracket is fastened to the mounting pad at a second position of the slot.

7. The light module of claim 6, wherein the internal surface comprises:

a mounting region;

a reflector region extending from the perimeter of the mounting region to a distal end; and

a decorative region extending from the distal end to a second distal end;

wherein the light sources are coupled to the mounting region within the heat sink cavity.

8. The light module of claim 6, further comprising a trim ring extending radially outward from substantially an end portion of the heat sink, wherein the trim ring and the heat sink are integrally formed as a single component thereby providing continuous non-movable contact between the trim ring and the heat sink.

9. A light module, comprising:

a heat sink comprising an internal surface surrounding a heat sink cavity formed therein,

one or more LED light sources coupled to a portion of the internal surface of the heat sink cavity;

a plurality of mounting pads disposed circumferentially around a portion of the heat sink to adjustably couple the light module to a housing having a five inch diameter cavity or a housing having a six inch diameter cavity, each mounting pad comprising;

a first receiving hole;

a second receiving hole,

wherein either the first receiving hole or the second receiving hole is coupled to a torsion spring,

wherein when the torsion spring is coupled to the first receiving hole, the light module is coupled to the housing having the five inch diameter cavity, and

wherein when the torsion spring is coupled to the second receiving hole, the light module is coupled to the housing having the six inch diameter cavity.

10. The light module of claim 9, wherein the first receiving hole and the second receiving hole are recessed openings formed within the mounting pad.

11. The light module of claim 9, further comprising a decorative region extending from a distal end to a second distal end;

and a trim ring extending radially outward from the second distal end, wherein the trim ring and the heat sink are integrally formed as a single component thereby providing continuous non-movable contact between the trim ring and the heat sink.
