Abstract

Se configura un dispositivo de iluminación LED de múltiples colores y específicamente un lente que comprende una abertura cilíndrica que se extiende hacia el lente desde una región de entrada de luz en la cual se configuran Ios LED. Una superficie se extiende a lo largo de la región de salida de luz del lente y una superficie exterior de TIR se extiende entre las regiones de entrada y salida de luz. Hay superficies de difusión en la pared lateral de la abertura cilíndrica y las superficies superiores y, si el control de brillo no es necesario, en la región de salida de luz. Las lunetas se pueden configurar en las superficies de pared lateral de la abertura cilíndrica y en la superficie exterior de TIR. Como ejemplo adicional, se fabrican elementos de difusión y posiblemente aumentan solamente en superficies seleccionadas, pero no en la región de salida de luz. Tres interacciones de luz en una primera parte de la luz y dos interacciones en una segunda parte de ¡a luz pueden mejorar la mezcla de colores y el control de haz. Estas interacciones incluyen dos refracciones ya sea con una reflexión intermedia o no.
