Abstract

L'invention concerne un système d'éclairage possédant une structure améliorée, ainsi qu'un appareil d'éclairage le comprenant, afin d'éviter la pollution lumineuse et de commander la répartition de lumière et l'illumination. L'appareil d'éclairage selon la présente invention convertit la lumière émise par une source de lumière en une lumière orientée vers le bas grâce à une unité de lentille comprenant une forme de lentille convexe orientée vers le bas ou une unité réfléchissante ayant une surface réfléchissante inclinée vers le bas, ce qui empêche la pollution lumineuse et améliore l'uniformité de l'illumination du sol afin de minimiser les zones non éclairées. En outre, en adoptant une structure dans laquelle plusieurs systèmes d'éclairage sont empilés, l'appareil d'éclairage permet de commander la répartition de lumière de manière à pouvoir être utilisé dans divers endroits, et permet d'augmenter l'intensité et la luminosité de la lumière émise par une source de lumière.
