FORENSIC LIGHT SOURCE AND ILLUMINATION METHOD

摘要

A forensic light source and method using an inventive light source comprising a short arc gas vapor discharge lamp is disclosed. A support structure is provided for supporting the source of light. A light guide having first and second ends, is coupled to the source of light at the first end to receive light from the source of light and transmit the light to the second end. The light guide is mounted on the support structure. A filter support member supports a plurality of filters. A portable hand holdable and movable light directing assembly is mounted on the second end of the light guide. The light directing assembly supports the filter support member and provides for movement of the filter support member to a plurality of positions. Each of the positions corresponds to a coupling of a selected one of the filters to the second end, whereby the light emitted from the second end is filtered by the selected filter while the emitted light is directed to various locations through movement of the light directing assembly. A dc power supply has a pulsating dc or constant voltage output.
