LIGHTING FIXTURE Russian patent published in 2003 - IPC

FIELD: instrumentation engineering; lighting fixtures. SUBSTANCE: incandescent lamp used in lighting fixture is supplied by thermoelectric pile at first junction of which container with evaporating liquid is placed and at second junction, metal radiator is mounted made in form of flat plate with dome in form of truncated cone. Incandescent lamp is placed in space limited by dome and is connected by wires to thermoelectric pile. Lighting fixture is mounted on support. Liquid filled into container evaporates, thus reducing temperature of first junction of thermoelectric pile. Difference of temperatures between junctions of thermoelectric pile provides potential difference between leads. Current flows through incandescent lamp series-connected to thermoelectric pile by means of wires and lamp lights. Metal radiator serves to increase temperature of second junction of thermoelectric pile owing to heat produced by incandescent lamp. EFFECT: provision of lighting fixture employing semiconductor thermoelectric generator to produce electric energy without external without external source of heat energy. 1 dwg
