Abstract

A lighting fixture having a housing with a base and an opposing openable end, and a flange spaced-apart from an edge at the openable end that extends radially from an exterior surface of the housing. A reflector defines a dished cavity and seats on the edge of the housing, thereby defining a recess between an edge portion of the reflector and the flange. A light source is received within the housing. A light transmissive cover received on the housing has a tab received in the recess for guiding the rotation of the cover thereon.

means for providing a source of light within the housing; and

a cover received on the housing, the cover having a port for communicating light from the source therethrough and an interior tab received past the flats and into the recess,

whereby the lighting fixture defines a pathway for communicating air past the reflector for communicating heat from the reflector to ambient air.

2. The under-cabinet lighting fixture as recited in claim 1, wherein the distal edge of the side wall defines at least one recessed opening therein and oriented longitudinally relative to the side wall, whereby a head of a fastener received through the opening is disposed apart from the distal edge of the side wall.

3. The under-cabinet lighting fixture as recited in claim 1, wherein the base has at least a thickened portion.

4. The under-cabinet lighting fixture as recited in claim 3, wherein the lamp bulb substantially aligns with the thickened portion of the base.

5. The under-cabinet light fixture as recited in claim 3, further comprising an insulating pad received within the housing in alignment with the thickened portion.

6. The under-cabinet lighting fixture as recited in claim 1, further comprising an open-ended can for receiving the housing through one end of the can and defining a plurality of pins extending outwardly from an opposing end of the can to define a gap between the can and a surface to which the can is mounted.

7. The under-cabinet light fixture as recited in claim 1, further comprising a recess in a side of the housing for matingly receiving a socket.

8. The under-cabinet light fixture as recited in claim 7, wherein the reflector defines a slot for receiving the socket upon seating the reflector on the open end of the housing, the socket extending through the slot inwardly of the cavity defined by the reflector for receiving the lamp bulb therein.

9. The under-cabinet lighting fixture as recited in claim 1, wherein the cover defines a central opening configured to receive a transparent sheet.

10. The under-cabinet lighting fixture as recited in claim 1, wherein lamp means comprises a socket received in the housing with a lamp bulb engaged to the socket.

11. The under-cabinet lighting fixture as recited in claim 1, further comprising a stop projecting radially from the housing between the flange and the edge, whereby the cover, guided by the tab traveling in the recess, rotates relative to the housing until stopped by the stop.

12. A lighting fixture, comprising:

a housing defining an open end that opposes a base, the base defining an opening, an integral flange extending radially from an exterior surface of a side wall of the housing, the flange spaced-apart from a distal edge of the side wall at the open end of the housing, and the side wall of the housing defining at least one recessed opening extending longitudinally from the distal edge of the side wall, whereby a head of a fastener received through the opening for securing the housing to a support is disposed apart from the distal edge of the side wall;

a reflector defining a dished cavity and at least one opening in the reflector, the reflector fixedly seated with fasteners on the edge of the housing, thereby defining a recess between an edge portion of the reflector and the flange, a perimeter edge of the reflector defining opposed flats radially inwardly of a remaining portion thereof;

a lamp mounted within the housing for emitting light; and

a cover received on the housing, the cover having a port for communicating light from the lamp and an interior tab received past the flats and into the recess,

whereby the lighting fixture defines a pathway for communicating air past the reflector for communicating heat of the lamp from the reflector to ambient air while the recess secures the cover thereon.

13. The lighting fixture as recited in claim 12, further comprising a stop projecting radially from the housing between the flange and the edge, whereby the cover, guided by the tab traveling in the recess, rotates relative to the housing until stopped by the stop.

14. The lighting fixture as recited in claim 13, wherein the base has at least a thickened portion.

15. The lighting fixture as recited in claim 14, wherein the lamp bulb substantially aligns with the thickened portion of the base.

16. The lighting fixture as recited in claim 14, further comprising an insulating pad received within the housing in alignment with the thickened portion.

17. The lighting fixture as recited in claim 14, further comprising an open-ended can for receiving the housing through one end of the can and means for defining a gap between the can and a surface to which the can is mounted.

18. The lighting fixture as recited in claim 17, wherein means for defining comprises a plurality of pins extending outwardly from an opposing end of the can.

19. The lighting fixture as recited in claim 17, wherein the housing defines a recess in a side of the housing for matingly receiving a socket;

and wherein the reflector defines a slot for receiving the socket upon seating the reflector on the open end of the housing, the socket extending through the slot inwardly of the cavity defined by the reflector for receiving a lamp bulb therein.

20. A light fixture, comprising:

a housing

defining an open end that opposes a base,

the base defining an opening for communication of air therethrough,

an integral flange spaced-apart from a distal edge of the side wall at the open end of the housing extends radially from the side wall,
