Actively cooled lighting trim apparatus
First Claim
1. An actively cooled lighting apparatus for use in conjunction with a first housing that receives a lamp, comprising:
- a second housing comprising an outer wall that fits within and spaced apart from the first housing to thereby define a space between the outer wall and the first housing;
a plate mounted to the second housing and having one or more vents that admit to the space; and
means for cooling the second housing by drawing a cooling fluid from outside the second housing, through the vents, through the space, and exhausting the cooling fluid around the lamp to outside the second housing.

Abstract
An actively cooled recessed lighting trim apparatus is disclosed. The trim apparatus comprises a trim housing that fits within a standard recessed lighting fixture housing to define a space between the lighting fixture housing and the trim housing; a trim ring or face that has a vent for admitting a cooling fluid to the space; and a means for actively cooling the space or the trim housing. The space forms a low-pressure plenum through which a cooling fluid is circulated. A thermal protector may be secured within the trim housing to turn off a lamp in the housing if the internal temperature of the space, or of the trim housing, becomes too hot. The cooling means, which may be a fan, actively draws a cooling fluid in through the vent of the trim ring, over the trim housing and the illuminated lamp, and exhausts warmed cooling fluid out though gaps between the lamp and the trim ring. Accordingly, high-wattage lamps may be used safely in recessed lighting installations.

24. A fan-cooled trim for use in conjunction with a first housing that receives a lamp, comprising:
-
a trim housing comprising an outer wall that fits within and spaced apart from the first housing to thereby define a space between the outer wall and the first housing; a plate mounted to the second housing and having one or more vents that admit a cooling fluid to the space; and a fan mounted in the second housing for cooling thereof by drawing a cooling fluid from outside the second housing, through the vents, through the space, and exhausting the cooling fluid around the lamp to outside the second housing.

25. A fan-cooled trim for use in conjunction with a recessed lighting housing that receives a lamp, comprising:
-
a trim housing comprising an outer wall that fits within and spaced apart from the recessed lighting housing to thereby define a space between the outer wall and the recessed lighting housing; a plate mounted to the second housing and having one or more vents that admit a cooling fluid to the space; a fan mounted in the second housing for cooling thereof by drawing a cooling fluid from outside the second housing, through the vents, through the space, and exhausting the cooling fluid around the lamp to outside the second housing; and thermal protection means in proximity to the second housing for selectively de-energizing the lamp when a temperature of the second housing exceeds a pre-determined value.

26. An actively cooled lighting apparatus for use in conjunction with a first housing for a lighting fixture, comprising:
-
a trim housing mounted within the first housing and spaced-apart therefrom to thereby define a space between the trim housing and the first housing; means mounted in the trim housing for receiving a lamp and spaced apart from the trim housing to thereby define a gap between the lamp and the trim housing when the lamp is mounted therein; and means for cooling the trim housing by drawing a cooling fluid from outside the trim housing, through the space, and exhausting the cooling fluid over the lamp through the gap to outside the trim housing. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
