Abstract:
1. A handheld searchlight for producing a high intensity beam of light output, said searchlight comprising: an elongated housing including a handle portion for gripping by a user; a head having a window opening for transmitting a light beam; a mechanical coupling between said housing and said head; a parabolic reflector mounted in said head facing said window opening, said reflector defining an aperture for accommodating a high-intensity lamp, said reflector having a longitudinal optical axis, wherein rotation of said head about said coupling causes movement of said parabolic reflector relative to the lamp along said optical axis, thereby changing a spread of the high-intensity light beam; a rotatable bezel ring comprising a non-threaded exterior surface and mounted on and rotatable relative to said head via a hinge member, responsive to a force applied on the exterior surface of said rotatable bezel ring; a plurality of detents on a surface of said head; a ball and spring plunger mounted in said rotatable bezel ring to releasably engage one of said plurality of detents, wherein said ball and spring plunger mechanically couples said rotatable bezel ring to said head; a filter ring mount connected to said rotatable bezel ring; and an optical filter mounted in said filter ring mount.
