IMAGE PROJECTOR WITH LED ARRAY ILLUMINATION

A projector for projecting an image includes an LED array (2) having separately-controllable LEDs for illuminating a spatial light modulator (SLM) (10) via illumination optics (8) with a converging beam. Projection optics (12) projects the image generated by the SLM. A reflective arrangement (16) ty...

Zusammenfassung:	A projector for projecting an image includes an LED array (2) having separately-controllable LEDs for illuminating a spatial light modulator (SLM) (10) via illumination optics (8) with a converging beam. Projection optics (12) projects the image generated by the SLM. A reflective arrangement (16) typically having four planar reflectors, is deployed between the LED array (2) and the illumination optics (8) so that light from each of LED illuminates a first region of the SLM by direct transmission from the LED via the illumination optics and additional regions of the SLM via reflection in the planar reflectors.
