Is coupled to the auxiliary fixing plate 115, the support rod 113 is to stably support the pedestal (110).
  • Both ends of the support bar 113 are rotatably coupled to the upper end of the pedestal 110 and the auxiliary fixing plate 115, and the length thereof is adjustable, so that the anchor bolts should be built in the process of embedding the initial anchor bolt into the concrete. There is room in the location.

Abstract

La présente invention concerne un système d'éclairage solaire et son procédé de commande, ledit système d'éclairage solaire comportant : un premier miroir réfléchissant qui est installé à l'intérieur du toit d'un bâtiment et réfléchit la lumière solaire incidente, un régulateur d'angle qui régule l'angle du premier miroir réfléchissant en faisant pivoter le miroir le long des axes X, Y et Z, un deuxième miroir réfléchissant qui est installé à l'extérieur du toit du bâtiment et réfléchit la lumière solaire projetée depuis le premier miroir réfléchissant, un troisième miroir réfléchissant qui est installé dans un endroit élevé adjacent au bâtiment et réfléchit la lumière solaire projetée depuis deuxième miroir réfléchissant vers un étage inférieur à l'ombre du bâtiment, une unité de suivi du soleil installée sur un côté du régulateur d'angle, et une unité de commande qui calcule un signal transmit depuis l'unité de suivi du soleil et contrôle le régulateur d'angle. La présente invention peut assurer le droit à la lumière du soleil et empêche une consommation d'énergie inutile en faisant rayonner la lumière du soleil vers une zone à l'ombre d'un étage inférieur d'un bâtiment à étages élevés qui n'est pas exposé directement à la lumière naturelle du soleil, et améliore également l'efficacité d'éclairage en suivant précisément la position du soleil et en régulant les miroirs réfléchissants.
