Side-emitting rod for use with an LED-based light engine

   
   

According to this invention, a side-emitting illumination device for uniformly distributing light is composed of an LED light source, a light-transmitting rod which permits total internal reflection, and outcoupling material affixed to an outer surface of the rod. Light enters the rod at one end and travels along the rod by total internal reflection. Light that hits the outcoupling material is angularly distributed based on the width of the outcoupling material.

Según esta invención, un dispositivo de la iluminación lado-que emite para uniformemente distribuir la luz se compone de una fuente de luz del LED, de una barra luz-que transmite que permita la reflexión interna total, y del material outcoupling puesto a una superficie externa de la barra. La luz entra en la barra en un extremo y viaja a lo largo de la barra por la reflexión interna total. Enciéndase que golpea el material outcoupling angular se distribuye basado en la anchura del material outcoupling.
