The invention relates to an illumination module for color display, preferably for use in data or video projectors as well as rear projection television sets, in which the light from at least three luminescent diodes (LEDs) or LED arrays of the base colors red, green and blue is collimated at a point provided for connection to a display unit and ranged on an optical axis of the illumination module. An LED or an LED array of a base color with a beam path (Lr) oriented in the direction of the display unit is arranged on the optical axis of the illumination module. For the purpose of color mixing, the LEDs and LED arrays of the other base colors are attached in such a way tat their beam paths (Lg, Lb) are laterally input in sequence under input angles (&#x3b1;, &#x3b2;) of &#x3c;90 degrees into the beam path (Lr) of the first base color.

Illumination module for color display

A fiber-optic arrangement for additive mixing of a plurality of light bundles comprises individual light-conducting cores for guiding laser light bundles independently and separately from one another, wherein each of the cores has a light entry location and a light exit location. The light-conducting cores are enclosed by a common cladding and are arranged so as to run alongside one another within said cladding. Propagation directions of the light bundles are identical in all cores. Light exit locations of all cores are arranged in a common plane oriented at a right angle to the propagation direction. The lateral distance between every two cores at the light exit locations are smaller than the lateral distance between the same cores at the light entry locations.
