Abstract

Un dispositivo de iluminación de LED - que comprende un elemento LED (3), - que comprende un colimador (1) que emite la luz emitida por el elemento LED (3) a través de una abertura de colimador (5) de manera colimada, - que comprende un reflector (7) que tiene una superficie reflectante cóncava semiparabólica (8), una cara irradiada (9), un punto focal (F) en la cara irradiada (9) y una cara de emisión (10) desde la cual se emite luz en una dirección de emisión del reflector (7) durante el funcionamiento y que forma un ángulo con la cara irradiada (9), en el que el colimador (1) está diseñado y/o dispuesto de modo que la luz colimada procedente del colimador (1), según se observa en la dirección de emisión, es irradiada hacia la cara irradiada (9) ya sea completamente delante de o completamente detrás del punto focal (F), caracterizado porque la unidad que consiste en el elemento LED (3) y el colimador (1) está diseñada de manera asimétrica para producir un gradiente en cuanto a la distribución de brillo.
