Abstract
Abstract A housing contains a rotating reflector and incandescent lamp in a transparent upper part. An impact-responsive switch in a base of the housing turns on the lamp and a motor to rotate the reflector. Fan blades on the reflector pull cooling air through inlet slits on the bottom part of the housing, past the lamp, and out one or more openings in the transparent part of the housing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
119 words
A condition-responsive warning light assembly comprising an incandescent lamp, a rotatable reflector for reflecting light from said lamp, means for rotating said reflector, impact-responsive switching means for initiating operation of said rotating means in response to a strong impact, housing means for containing said lamp, reflector, rotating means, and impact-responsive switching means, said housing having a translucent upper portion for allowing the passage of light from said lamp and reflector therethrough and said reflector rotatable with respect to said housing means, and means providing circulation of air through said housing to cool said lamp, said means comprising air inlet means, air outlet means and means for moving air from said inlet means through said outlet means past said lamp.
Claim 2
Dependent Claim
119 words
A condition-responsive warning light assembly comprising an incandescent lamp, a rotatable reflector for reflecting light from said lamp, means for rotating said reflector, impact-responsive switching means for initiating operation of said rotating means in response to a strong impact, housing means for containing said lamp, reflector, rotating means, and impact-responsive switching means, said housing having a translucent upper portion for allowing the passage of light from said lamp and reflector therethrough and said reflector rotatable with respect to said housing means, and means providing circulation of air through said housing to cool said lamp, said means comprising air inlet means, air outlet means and means for moving air from said inlet means through said outlet means past said lamp.
Claim 3
Dependent Claim
64 words
An assembly as recited in claim 1 wherein said impact-responsive switching means comprises a conductive ball, a conically shaped depression in a base plate for receipt of said ball, a spring contact for normally retaining said ball in said depression, and a contact plate, said ball completing a circuit between said contact plate and said spring contact when said assembly is subjected to impact.
Claim 4
Dependent Claim
34 words
An assembly as recited in claim 2 further comprising manually operable reset means for moving said spring contact with respect to said ball to reset said switching means after termination of an impact condition.
Claim 5
Dependent Claim
40 words
An assembly as recited in claim 1 further comprising means for mounting said incandescent lamp for rotation with said reflector so that the axis of projection of said reflector makes an acute angle with the longitudinal axis of said lamp.
Claim 6
Dependent Claim
65 words
An assembly as recited in claim 1 wherein said means for moving air from said air inlet means through said air outlet means comprises at least one fan blade mounted for rotation with said rotatable reflector, and wherein said air inlet means is disposed at a bottom portion of said housing, and said air outlet means is disposed at a top portion of said housing.
