Title (EN) OPTICAL SYSTEM FOR LED LIGHTING EQUIPMENT
(FR) SYSTÈME OPTIQUE DESTINÉ À UN DISPOSITIF D'ÉCLAIRAGE À LED
Abstract:
(EN) A LED (12) lighting appliance (15), comprising an optical system with refracted and diffused light, characterized in that said optical system includes at least one refractive element (10), made of transparent material and constitute of one or more lenses (11) positioned in correspondence to the respective LEDs (12), and at least one diffusive element, constituted by a superficial portion (20, 30) made of a diffusing material preferably at high reflectance, said superficial portion (20, 30) being placed in close proximity to said refractive element, in a way to obtain a photometric emission output at high visual comfort for the user, together at a high efficiency.
(FR) La présente invention concerne un appareil d'éclairage (15) à LED (12), comprenant un système optique dont la lumière est réfractée et diffusée, caractérisé en ce que ledit système optique inclut au moins un élément de réfraction (10) qui est composé d'un matériau transparent et qui est constitué d'une ou plusieurs lentilles (11) positionnées de manière à correspondre aux LED (12) respectives, ainsi qu'au minimum un élément de diffusion qui est constitué d'une partie superficielle (20, 30) composée d'un matériau diffusant ayant de préférence un facteur de réflexion élevé, ladite partie superficielle (20, 30) étant placée très près dudit élément de réfraction, de façon à obtenir une sortie d'émission photométrique avec un grand confort visuel pour l'utilisateur, conjointement avec une efficacité élevée.
