Abstract

Se provee un aparato difusor óptico, para usarse adyacente a un emisor de luz en un componente de iluminación para producir la salida de luz con color mezclado deseada; el aparato incluye un primer panel difusor y un segundo panel difusor conectado al primer panel difusor; el primer panel difusor y el segundo panel difusor están configurados y dispuestos de tal manera que, cuando el aparato está colocado para operación dentro del componente, luz emitida por el emisor de luz a un ángulo mayor que un umbral pre-predeterminado con respecto a una línea central del emisor pasará a través de ambos el primer panel difusor y el segundo panel difusor, mezclando así los colores de la luz hacia la salida de luz de color-mezclado deseada.
