Title (EN) LIGHT-EMITTING DIODE ILLUMINATING OPTICAL DEVICE
(FR) DISPOSITIF OPTIQUE D'ECLAIRAGE A DIODES ELECTROLUMINESCENTES
Abstract:
(EN) The invention concerns an illuminating device using light-emitting diode (LED) properties, with high luminosity, very economical, redirected and scattered by one or several transparent optical components, providing illumination powered either by the power grid, or solar or wind turbine energy. The device consists in particular of a housing (7) containing the printed circuit (10) sliding on four rods (17), the transparent optical component (1) is assembled to the housing (7) with four screws (13). The endless micrometer screw (12) vary by screwing and unscrewing the illuminating angle (F) by modifying the focal distance between the LED's (5) and the polished concave optical housings (2) positioned in the same axis. The printed circuit (10) bearing the LED's (5) is supplied with electric power by the supply line (15). The inventive device is designed for illumination, in particular when there is need for an economical self-powered illumination device.
(FR) La présente invention concerne un dispositif d'éclairage utilisant les propriétés de diodes électroluminescentes ou LED, à grande luminosité, très économes, redirigée et étalée par une ou plusieurs pièces optiques transparentes, permet l'éclairage alimenté soit par le secteur électrique, soit au moyen des énergies solaires ou éoliennes. Le dispositif est constitué notamment du boîtier (7) contenant le circuit imprimé (10) coulissant sur 4 tiges (17), la pièce optique transparente (1) est assemblée au boîtier (7) par 4 vis (13). La vis micrométrique sans fin (12) permet en vissant ou dévissant de faire varier l'angle d'éclairement (F) en modifiant la distance focale entre les LED (5) et les logements optiques concaves polis (2) positionnés dans le même axe. Le circuit imprimé (10) portant les LED (5) est alimenté en énergie électrique par le fil d'alimentation (15). Le dispositif selon l'invention est destiné à l'éclairage, surtout lorsqu'il faut recourir économiquement à un dispositif autonome en alimentation électrique.
