Abstract
Abstract A multi-section multi-purpose hand light incorporates a shade casing, a head cover, a refraction hood, red filter lens and a body comprised of a number of cylindrical sections. The red filter lens can be releasably fastened to the retractable refraction hood. The light being emitted thereby will be a focused red light beam surrounded by an aureole of white light. This hand light may serve as a striking signal for help where needed to facilitate search and rescue efforts by a tracing team. The intensity of illumination can be increased by an increased number of the cylindrical sections. Spare bulbs or replacement parts can be stored in the bottom section of the body. The hand light also serves as a regular hand light by removing the red filter lens from the hood and coupling it to the bottom section of the hand light.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
207 words
A hand light comprising: an elongate body having a forward end and a rear end and including a plurality of open-ended sections arranged end to end, the length of the body being adjustable by varying the number of sections constituting the body; a transparent refraction hood fixed to and extending away from the forward end of the body in tapering fashion; a transparent head cover fixed to the refraction hood over its free end; a source of light in the body which emits light into the space defined by the refraction hood and the head cover; a shade casing having a front edge and fixed to the forward end of the body, the casing being capable of sliding telescopic-like movement relative to the body between an extended position wherein the front edge of the casing extends beyond the forward end of the body to surround the refraction hood, and a withdrawn position wherein substantially the entire casing surrounds the body; and a color filter lens releasably connected to the head cover, whereby the illumination pattern when the lens is connected to the head cover and the shade casing is in the extended position consists of a central color beam surrounded by an annular beam of white light.
