Title
(EN) LOW LUMINANCE LIGHTING
(FR) ÉCLAIRAGE DE FAIBLE LUMINANCE
Abstract
(EN) Novel and advantageous lighting modules and systems are provided. Lighting modules and systems according to embodiments of the subject invention can be low- luminance, high-efficiency, low-glare lighting modules. For example, a lighting system can utilize multiple layers of efficient optics to spread light from multiple light sources (e.g., a grid of point sources) over a larger luminous surface. The larger luminous surface can maintain the controllability, directionality, and efficiency of a single point source, while significantly reducing the glare. The surface can appear uniformly lit, or substantially uniformly lit, and no dark boundaries may be present between the individual light sources.
(FR) L'invention concerne des modules et des systèmes d'éclairage novateurs et avantageux. Les modules et les systèmes d'éclairage selon des modes de réalisation de la présente invention peuvent être des modules d'éclairage de faible luminance, de haut rendement et de faible éblouissement. Par exemple, un système d'éclairage peut utiliser de multiples couches d'optique efficace pour diffuser la lumière issue de multiples sources de lumière (par exemple, un réseau de sources ponctuelles) sur une plus grande surface lumineuse. La plus grande surface lumineuse peut maintenir la contrôlabilité, la directionnalité et le rendement d'une seule source ponctuelle, tout en réduisant significativement l'éblouissement. La surface peut sembler éclairée uniformément, ou éclairée sensiblement uniformément, et aucune frontière obscure ne peut être présente entre les sources de lumière individuelles.
