Abstract

Abstract This invention is concerned with a floodlight assembly provided with an apparatus for dissipating heat from the vicinity of a high wattage iodine quartz lamp enclosed therein; the floodlight housing being of relatively small dimensions in comparison to floodlight housings heretofore employed. The invention contemplates a mass of metal bored to receive a high wattage iodine quartz lamp and provided with a shaped surface remote from the said lamp and means for dissipating heat from the vicinity of the said lamp by forming a heat dissipating mass adaptable to enclose the lamp without contacting it.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 170 words
In a floodlight assembly having a hollow housing with a lamp supporting means in one end and a light reflecting means in the other end, said lamp supporting means having electrical terminals adapted to be energized by a source of current and means to energize a lamp supportable thereby from said electrical terminals to cause the lamp to emit light and radiate heat, the improvement comprising a heat dissipating means mounted on the housing intermediate the reflecting means and lamp supporting means, said heat dissipating means having an inner wall which defines an aperture formed therein through which a portion of a lamp may be inserted and be surrounded by said wall without contacting said wall and wherein said heat dissipating means comprise a mass having a pair of bifurcated members formed to surround the base of said lamp without contacting said base, said bifurcated members defining an end face on said heat dissipating means, and said end face also comprising an arcuately sloped portion terminating in said bifurcated members.
Claim 2
Dependent Claim 170 words
In a floodlight assembly having a hollow housing with a lamp supporting means in one end and a light reflecting means in the other end, said lamp supporting means having electrical terminals adapted to be energized by a source of current and means to energize a lamp supportable thereby from said electrical terminals to cause the lamp to emit light and radiate heat, the improvement comprising a heat dissipating means mounted on the housing intermediate the reflecting means and lamp supporting means, said heat dissipating means having an inner wall which defines an aperture formed therein through which a portion of a lamp may be inserted and be surrounded by said wall without contacting said wall and wherein said heat dissipating means comprise a mass having a pair of bifurcated members formed to surround the base of said lamp without contacting said base, said bifurcated members defining an end face on said heat dissipating means, and said end face also comprising an arcuately sloped portion terminating in said bifurcated members.
Claim 3
Dependent Claim 173 words
In a floodlight assembly having a hollow housing with a lamp supporting means in one end and a light reflecting means in the other end, said lamp supporting means having electrical terminals adapted to be energized by a source of current and means to energize a lamp supportable thereby from said electrical terminals to cause the lamp to emit light and radiate heat, the improvement comprising a heat dissipating means mounted on the housing intermediate the reflecting means and lamp supporting means, said heat dissipating means having an inner wall which defines an aperture formed therein through which a portion of a lamp may be inserted and be surrounded by said wall without contacting said wall, said heat dissipating means comprising an annular mass having an outer wall which includes an end face and a side face, said end face being formed at an angle with respect to the axis of the annular mass and merging into said side face, and said side face being adapted to being supported in said floodlight housing.
Claim 4
Dependent Claim 173 words
In a floodlight assembly having a hollow housing with a lamp supporting means in one end and a light reflecting means in the other end, said lamp supporting means having electrical terminals adapted to be energized by a source of current and means to energize a lamp supportable thereby from said electrical terminals to cause the lamp to emit light and radiate heat, the improvement comprising a heat dissipating means mounted on the housing intermediate the reflecting means and lamp supporting means, said heat dissipating means having an inner wall which defines an aperture formed therein through which a portion of a lamp may be inserted and be surrounded by said wall without contacting said wall, said heat dissipating means comprising an annular mass having an outer wall which includes an end face and a side face, said end face being formed at an angle with respect to the axis of the annular mass and merging into said side face, and said side face being adapted to being supported in said floodlight housing.
Claim 5
Dependent Claim 18 words
The device according to claim 4, said end face flaring inwardly toward said side face and merging thereinto.
Claim 6
Dependent Claim 36 words
The device according to claim 5, said inner wall being formed substantially parallel with respect to the axis of said annular mass and said side face being formed substantially parallel with respect to said inner wall.
