摘要:
An illumination system (10) for spot illumination comprising a tubular reflector (2) with a reflective inner surface, the tubular reflector (2) having an entrance aperture (7) and an exit aperture (8) being larger than the entrance aperture (7); and a light-source array (1) comprising a plurality of light-sources (13a-c; 30a-d, 31a-d, 32a-d) arranged to emit light into the tubular reflector (2) at the entrance aperture (7) thereof. At least one of the tubular reflector (2) and the light-source array (1) is configured in such a way that each symmetry state of the light-source array (1) is different from any symmetry state of the tubular reflector (2). By avoiding coinciding symmetry states, the occurrence of preferred directions of the emitted light can be reduced, whereby the spatial homogeneity with respect to intensity and, where applicable, color of the emitted light can be improved.

An LED module is described with a base 10 made out of a heat conducting material. An LED element (32) is arranged in a cavity (11) of the base. A collimator reflector (70) is formed by reflective surfaces (24, 64, 66a). Three of these reflective surfaces (66a, 66b, 64) are provided on a plastic insert (60) received in the cavity (11). A further reflective surface (24) is provided on the base (10) itself. This surface (24) has a straight border line (50). The collimator reflector (70) is arranged to reflect light from the LED (32) so that a cut-off (72) is formed by the straight border line (50). By thus integrating the cut-off, as the most critical optical element, into the base (10) itself, high accuracy is achieved.

The invention relates to an LED collimator element (1; 20) which can be used in particular for motor vehicle headlights. It comprises an LED (2; 23), of which the emitted light can be emitted essentially directly into an emission angle region of the LED collimator element (1; 20), and a collimator (3; 22) which deflects the light which is not emitted in the emission direction into the emission angle region. The LED collimator element (1; 20) is designed to be asymmetrical at least with respect to a sectional plane (4) so that a defined non-uniform light intensity distribution is achieved in an emission plane (10; 26) of the LED collimator element (1; 20) which is orthogonal to the sectional plane (4) and to the main emission direction.
