Abstract

An LED module includes a circular body member for mounting in a lighting assembly or luminaire that can be oriented in an opening in the luminaire by rotating the module about a center axis to a predetermined position to direct the light in a selected pattern. A mounting assembly captures the LED modules between top and bottom mounting members. The LED modules include a heat conducting body coupled to the mounting assembly to conduct heat away from the LED and PCB. A top side of the LED body cooperates with the mounting assembly. A bottom side of the LED body has a cavity supporting a PCB with a plurality of LEDs. A lens body is coupled to the bottom side of the body of the LED module to direct the light to the target area.

First claim

What is claimed is:

1. An LED module comprising:
a one-piece body member made from a heat conducting material, said body member having a circular outer side edge adapted for mounting rotatably in an opening in a support and being rotatable about an axis of the opening, a top side and a bottom side, a central axis extending between said top side and said bottom side, a plurality of heat conducting fins extending from said top side and a mounting surface on a bottom side, said mounting surface being inclined with respect to a plane of said bottom side of said one piece body member and inclined with respect to said central axis; and
an LED assembly fixed to said inclined mounting surface for directing light at an incline with respect to said plane of said bottom side and said central axis.

2. The LED module of claim 1 , wherein
said center axis of said body member extends substantially perpendicular to a plane of said bottom side, and said body member adapted for mounting in a lighting assembly and rotatably adjusting said body member about said center axis of said body member and with respect to said lighting assembly.

3. The LED module of claim 1 , further comprising
a lens body coupled to said bottom side of said body member of said module for directing light from said LED assembly in a direction substantially perpendicular to said mounting surface.

4. The LED module of claim 1 , wherein said LED assembly further comprises
a first electrical connector coupled to said body member, and
a second electrical connector adapted for coupling with a first electrical connector to a second LED module to form an LED array.

5. The LED module of claim 2 , wherein said body member further comprises
a first member extending from the top side of said body member for mating with a hole in a mounting assembly of a luminaire housing and enabling rotation of said LED module about said center axis with respect to the lighting assembly; and
a second member extending from the top side of said body member adapted for mating with a registration hole of the mounting assembly to prevent rotation of said LED module with respect to said lighting assembly.

6. The LED module of claim 1 , further comprising
a lens body coupled to said bottom side of said body member, said lens body having a lens aligned with said LED assembly for focusing light from said LED assembly.

7. The LED module of claim 1 , wherein
said bottom side of said body member has a recess, and where said mounting surface is formed within said recess.

8. The LED module of claim 4 , further comprising
a recess in said top surface, and said first electrical connector mounted in said recess, said first electrical connector being operatively connected to said LED assembly.

9. The LED module of claim 4 , wherein
said LED assembly is fixed to said mounting surface by a thermally conducting adhesive.

10. The LED module of claim 1 , wherein
said body member has a concave portion in said bottom side defining a recess, said recess having a first surface inclined with respect to said plane of said bottom side for defining said inclined mounting surface and a second inclined surface extending substantially perpendicular to said mounting surface and adapted for directing light from said LED along an axis substantially perpendicular to said mounting surface.

11. The LED module of claim 10 , further comprising
a lens body having a convex portion received in said concave portion of said body member, said lens body having a lens aligned with said LED assembly in a plane substantially parallel to said mounting surface for focusing light from said LED assembly at an incline with respect to said plane of said bottom side.

12. The LED module of claim 11 , wherein
said lens body has a shape complementing the shape of said bottom side of said body member and has an outer edge mating with and coupled to an outer edge of said body member.

13. A luminaire comprising:
a housing having a mounting assembly;
a plurality of LED modules coupled to said mounting assembly, each of said LED modules being independently positionable with respect to said luminaire to direct light in a selected target area with respect to a respective LED module, each said LED module comprising
a one-piece heat conducting body member having a circular outer side edge and being coupled directly to said mounting assembly, a top side with a plurality of heat conducting fins and a bottom side having an inclined mounting surface, and a central axis extending between said top side and said bottom side, said mounting surface being oriented at an incline with respect to a plane of said bottom side of said body member, an outer edge of said circular outer edge being coupled to said mounting assembly of said housing for rotatable adjustment about said central axis in said housing, and
an LED assembly coupled to said inclined mounting surface for directing light to said selected target area at an incline with respect to the plane of the bottom side of said body member and with respect to a plane of a bottom side of said housing.

14. The luminaire of claim 13 , wherein
each said LED module is rotatably received in an opening in said mounting assembly and is independently rotatable in said housing with respect to said mounting surface about an axis substantially perpendicular to a plane of said housing.

15. The luminaire of claim 13 , further comprising
a lens body coupled to said bottom side of said module for directing light from said LED assembly to said selected target area.

16. The luminaire of claim 13 , wherein each said LED assembly further comprises
a first electrical connector coupled to a top side of said body member, and
a second electrical connector coupled to a first electrical connector of a second LED module for connecting said LED modules in series.

17. The luminaire of claim 13 , wherein said mounting assembly comprises
a bottom wall having an opening receiving said body member of said LED modules, and
a top wall overlying said body member of said LED modules and coupled to said bottom wall and capturing said LED modules therebetween, said LED modules being rotatable with respect to said top wall and bottom wall.

18. The luminaire of claim 17 , wherein each of said LED modules further comprise
a first member extending from the top side of said body for mating with a first opening in said top wall of said mounting assembly of the housing to enable rotational adjustment of said LED module with respect to said housing, and
a second member extending from the top side of the body for registration with a registration hole in said top wall of said mounting assembly for fixing the orientation of said LED module.

19. The luminaire of claim 18 , wherein
at least a portion of said first member of said body member extends through said opening in said top wall.

20. The luminaire of claim 13 , wherein
said body member has a concave recess in said bottom side, said recess having said mounting surface formed therein and a second surface oriented in a plane substantially perpendicular to said mounting surface.

21. The luminaire of claim 20 , said modules further comprising
a lens body coupled to said bottom side of said body member, said lens body having a convex portion received in said concave recess of said body member, said lens body having a light-transmitting lens portion oriented in a plane substantially parallel to said mounting surface and overlying said LED assembly for
