SCANNING ILLUMINATION SYSTEM

摘要

The invention relates to a scanning illumination system for illuminating a display device. The illumination system has a light-emission window (2) for emitting light in the direction of the display device (3) and a reflector (8) for reflecting light. The reflector is arranged parallel to and opposite the light emission window. The illumination system further has a plurality of elongated light sources (6, 6', 6", ...) arranged between the light-emission window (2) and the reflector (8), wherein each light source (6, 6', 6", ...) is provided with a single reflective layer at the side facing the light emission window (2) for reflecting part of the emitted light by the light source in the direction of the reflector (8). The reflective layer forms an elongated concave reflecting surface relative to the light source (6, 6', 6", ...). The illumination system further has an elongated, at least partly reflective light barrier (9, 9', 9", ...) positioned between a pair of neighboring light sources, the light barrier having a substantially rectangular shape and being substantially free from adsorption of light generated by the light sources.
