Abstract
(EN)
The present invention provides a light focusing apparatus comprising: a Fresnel lens having a predetermined focus; a first reflector spaced apart from the Fresnel lens, and formed on a first virtual parabolic trajectory having the same focus as that of the Fresnel lens; and a second reflector formed on a second virtual parabolic trajectory which is spaced apart from the first parabolic trajectory, and which has the same focus as those of the Fresnel lens and the first parabolic trajectory, wherein the second reflector is spaced apart from the Fresnel lens and the first reflector. The present invention also provides a solar energy generating apparatus. The light focusing apparatus of the present invention minimizes loss area (RA), minimizes the size thereof and the size of the solar energy generating apparatus, and improves the light focusing rate.

La présente invention concerne un appareil de focalisation de lumière comportant: une lentille de Fresnel comprenant un foyer prédéterminé ; un premier réflecteur espacé de la lentille de Fresnel, et formé sur une trajectoire parabolique virtuelle ayant le même foyer que celui de la lentille de Fresnel ; et un second réflecteur formé sur une seconde trajectoire parabolique virtuelle, et qui a le même foyer que ceux de la lentille de Fresnel et de la première trajectoire parabolique virtuelle, le second réflecteur étant espacé de la lentille de Fresnel et du premier réflecteur. La présente invention concerne également un appareil de génération d'énergie solaire. L'appareil de focalisation de la lumière selon la présente invention minimise la surface de perte (RA), minimise sa taille et la taille de l'appareil de génération d'énergie solaire, et améliore le taux de focalisation de lumière.
