INTEGRATED PROJECTION UNIT IN PARTICULAR FOR PROJECTING IMAGES AND/OR LIGHT BEAMS OF PREDETERMINED GEOMETRY

摘要

An integrated projection unit (1), in particular for projecting images and/or light beams of predetermined geometry, has a casing (2) in which are housed a solid-state light source (3), in particular a light emitting diode (LED) ; a holder (4) for supporting, at a given distance from the source, at least one object whose image is to be projected; a first optical element (6) associated with the source (3) and for directing the light from the source (3) onto the holder (4) ; and a second optical element (7) carried by the casing (2) at a given distance from the holder (4). The first optical element (6) is a total internal reflection collector associated with the source (3) and interposed between the source (3) and the holder (4), and the second optical element (7) is a projection lens (or group of projection lenses).
