Title
(EN) SOLAR TRACKING REFLECTOR SYSTEM FOR STRUCTURE LIGHTING
(FR) SYSTÈME DE RÉFLECTEUR DE POURSUITE SOLAIRE POUR ÉCLAIRAGE DE STRUCTURE
Abstract
(EN)
A solar tracking device (100; 1000) is mounted above a skylight of a building. An array of mirrors (150, 152, 154; 1110, 1114, 1118) is rotated at a rate of one revolution per day to reflect sunlight through the skylight. A control circuit (610; 1500) intermittently adjusts the angular position of the tracking device so that the mirrors face the sun. A solar array (130; 1200) charges an internal energy storage system (132; 1520, 1522) so that no external power source is needed. The control circuit (610; 1500) within the tracking device (100; 1000) reduces the power requirements at night and when not moving the tracking device during the daytime to conserve electrical energy.

L'invention concerne un dispositif de poursuite solaire (100; 1000) monté au-dessus d'un puits de lumière sur un bâtiment. Un ensemble de miroirs (150, 152, 154; 1110, 1114, 1118) est mis en rotation à une vitesse d'une révolution par jour pour réfléchir la lumière solaire à travers le puits de lumière. Un circuit de commande (610; 1500) règle de façon intermittente la position angulaire du dispositif de poursuite pour que les miroirs soient dirigés vers le soleil. Un panneau solaire (130; 1200) charge un système de stockage d'énergie interne (132; 1520, 1522), de sorte qu'aucune source d'alimentation externe n'est nécessaire. Le circuit de commande (610; 1500) à l'intérieur du dispositif de poursuite (100; 1000) réduit la puissance requise pendant la nuit et lorsque le dispositif de poursuite n'est pas déplacé pendant la journée de façon à préserver l'électricité.
