Title (EN) THERMOELECTRICALLY POWERED PORTABLE LIGHT SOURCE
(FR) SOURCE DE LUMIÈRE PORTATIVE ALIMENTÉE THERMOÉLECTRIQUEMENT
Abstract:
(EN) Provided is a portable, thermoelectrically powered device, such as a flashlight or headlamp. The device comprises at least one thermoelectric generator for extracting body heat from a user, the Thermoelectric generator located on and extending through an elongated open ended outer shell, a heat sink in contact with an inner surface of the thermoelectric generator and configured to provide an elongated first cooling channel therethrough, circuitry in electrical communication with the thermoelectric generator, the circuitry comprising a transistor oscillator, step-up transformer and a capacitor, the circuitry in electrical communication with a power sink, such that in use, a temperature gradient across the thermoelectric generator is sufficient to result in generation of at least about 25 μ\Ν of power.
(FR) L'invention concerne un dispositif alimenté thermoélectriquement portatif, par exemple une lampe de poche ou une lampe frontale. Le dispositif comprend au moins un générateur thermoélectrique permettant d'extraire la chaleur corporelle d'un utilisateur, le générateur thermoélectrique étant situé sur et s'étendant à travers une coque extérieure à extrémité ouverte allongée, un dissipateur thermique en contact avec une surface intérieure du générateur thermoélectrique et servant à réaliser un premier canal de refroidissement allongé à travers le générateur, des circuits en communication électrique avec le générateur thermoélectrique, les circuits comprenant un oscillateur à transistors, un transformateur élévateur et un condensateur, les circuits étant en communication électrique avec un absorbeur de puissance, de sorte qu'en fonctionnement, un gradient de température à travers le générateur thermoélectrique est suffisant pour résulter dans la génération d'au moins environ 25 µW de puissance.
