Title (EN) IMAGE GENERATING UNIT, IMAGE PROJECTING APPARATUS, AND HEAT SINK
(FR) UNITÉ DE GÉNÉRATION D'IMAGES, APPAREIL DE PROJECTION D'IMAGE ET DISSIPATEUR THERMIQUE
Abstract:
(EN) An image generating unit includes an image generating part configured to generate an image from illumination light; a driving magnet configured to generate a magnetic field; a driving coil arranged in the magnetic field of the driving magnet; a heat radiating part coupled to the image generating part and configured to radiate heat of the image generating part. The driving magnet and the driving coil move the image generating part and the heat radiating part. The driving coil is placed at the heat radiating part via a substance, thermal conductivity of the substance being lower than thermal conductivity of the heat radiating part.
(FR) Une unité de génération d'images comprend une partie de génération d'images configurée pour générer une image à partir de la lumière d'éclairage; un aimant d'entraînement configuré pour générer un champ magnétique; une bobine d'entraînement disposée dans le champ magnétique de l'aimant d'entraînement; une partie de rayonnement de chaleur couplée à la partie de génération d'images et configurée pour rayonner de la chaleur de la partie de génération d'images L'aimant d'entraînement et la bobine d'entraînement déplacent la partie de génération d'images et la partie de rayonnement de chaleur La bobine d'entraînement est placée au niveau de la partie de rayonnement de chaleur par l'intermédiaire d'une substance, la conductivité thermique de la substance étant inférieure à la conductivité thermique de la partie de rayonnement de chaleur
