Abstract

La invención se refiere a difusores ópticos de luz para su uso con fuentes de luz puntuales, tal como la iluminación LED. Los difusores ópticos logran un equilibrio óptimo de transmisión de luz y de poder de cobertura. El difusor óptico de luz es una matriz de plástico transparente, tal como la resma Plexiqlas(r) de Arkema Inc., que tiene partículas orgánicas dispersas dentro de la matriz. Las partículas son perlas reticuladas que tienen tamaños y cargas de partículas específicos. Pueden combinarse diferentes perlas para proporcionar propiedades adicionales, tales como una superficie texturizada, y para optimizar el poder de cobertura y la transmisión de luz. La invención también se refiere a un dispositivo luminoso que contiene al menos un diodo emisor de luz y una cubierta hecha del difusor óptico de luz. La invención se refiere además a un método para evaluar el poder de cobertura.
