Claim 4

The light of claim 1 wherein said limiting means includes an interlocking bracket associated with said housing and an outer lip of said reflector.

Claim 5

The light of claim 1 wherein said reflector assumes a parabolic shape in said second position.

Claim 6

The light of claim 1 wherein said means for moving includes a first means engageable with the reflector on the back side of the reflector opposite the light source, and a second means for driving said first means in opposite linear directions.

Claim 7

The light of claim 5 wherein said first means includes a lead screw and said second means includes a gear train and drive motor.

Claim 8

The light of claim 5 wherein said first means includes a lead screw and said second means includes a worm gear and drive motor.

Claim 9

The light of claim 1 wherein said reflector has reliefs therein.

Claim 10

The light of claim 1 including switch means operatively associated with said means for moving for limiting the movement thereof in opposite directions.

Claim 11

The light of claim 5 including a pair of switches spaced apart and engageable with said first means for controlling and limiting movement of said first means and in turn said reflector.

Claim 12

The light of claim 1 wherein said reflector has a central aperture for receiving said light source and positioning said light source on the front side of said reflector.

Claim 13

The light of claim 11 wherein said means for moving includes a lead screw and said reflector includes means on its back side for holding an end of said lead screw.

Claim 14

The light of claim 12 wherein said means for moving further comprises means for selectively driving said lead screw and means secured within said housing for supporting said driving means.

Claim 15

The light of claim 13 including at least one switch disposed within the path of travel of said lead screw and engageable therewith, said switch being coupled to said driving means for interrupting operation thereof when said lead screw has reached one of its limiting positions.

Claim 16

The light of claim 14 including a pair of spaced switches both of which couple to said drive means, one of said switches being normally open and the other normally closed.

Claim 17

The light of claim 1 wherein said limiting means of the housing includes a bracket having a flange extending in direction of the opening and said reflector has a lip engageable with the flange to limit the position of greatest curvature of the reflector.

Claim 18

A light of the searchlight type comprising; a housing having an opening through which light is transmitted, a curved reflector disposed in said housing, a light source positioned at the center of said reflector, and means within said housing for moving at least the center of said reflector between opposite positions wherein said reflector has less of a curvature in a first position and a greater curvature in a second position, said reflector having a central aperture for receiving said light source and positioning said light source on the front side of said reflector, said means for moving at least the center of said reflector including a lead screw and means for selectively driving said lead screw and means secured within said housing for supporting said driving means, said reflector including means on its backside for holding an end of said lead screw, said means for selectively driving said lead screw including a drive motOr and a series of interengageable gears one of which has a central toothed aperture for receiving said lead screw.

Claim 19

A light of the searchlight type comprising; a housing having an opening through which light is transmitted, a curved reflector disposed in said housing, a light source positioned at the center of said reflector, and means within said housing for moving at least the center of said reflector between opposite positions wherein said reflector has less of a curvature in a first position and a greater curvature in a second position, said reflector having a central aperture for receiving said light source and positioning said light source on the front side of said reflector, said means for moving at least the center of said reflector including a lead screw and means for selectively driving said lead screw and means secured within said housing for supporting said driving means, said reflector including means on its backside for holding an end of said lead screw, said means for selectively driving said lead screw including a drive motOr and a series of interengageable gears one of which has a central toothed aperture for receiving said lead screw.

Claim 20

A light of the search light type comprising; a housing having an opening through which the light is transmitted, a curved reflector disposed in said housing, a light source positioned at the center of said reflector, and means within said housing for moving at least the center of said reflector between opposite positions wherein said reflector has less of a curvature in a first position and a greater curvature in a second position, said reflector having a central aperture for receiving said light source and positioning said light source on the front side of said reflector, said means for moving at least the center of said reflector including a lead screw and means for selectively driving said lead screw and means secured within said housing for supporting said driving means, said reflector including means on its backside for holding an end of said lead screw, said means for selectively driving said lead screw including a drive motor, a worm gear rotated by said drive motor and a drive gear having a central toothed aperture for receiving said lead screw.

Claim 21

A light of the search light type comprising; a housing having an opening through which the light is transmitted, a curved reflector disposed in said housing, a light source positioned at the center of said reflector, and means within said housing for moving at least the center of said reflector between opposite positions wherein said reflector has less of a curvature in a first position and a greater curvature in a second position, said reflector having a central aperture for receiving said light source and positioning said light source on the front side of said reflector, said means for moving at least the center of said reflector including a lead screw and means for selectively driving said lead screw and means secured within said housing for supporting said driving means, said reflector including means on its backside for holding an end of said lead screw, said means for selectively driving said lead screw including a drive motor, a worm gear rotated by said drive motor and a drive gear having a central toothed aperture for receiving said lead screw.
