Abstract
The invention relates to a light module (1) for an illumination device (20), in particular for a headlight, for a motor vehicle. The light module (1) comprises a plurality of light sources (2) for emitting light beams (4, 5), at least one primary optical unit (6; 12) for focusing the emitted light beams (4a, 5a), a stop arrangement (8) in the beam path of the focused light beams (4b, 5b), and at least one secondary optical unit (9) for imaging the focused light beams (4b, 5b) which passed the stop arrangement (8) on a roadway in front of the motor vehicle in order to generate a desired light distribution. In order to be able to implement a particularly compact illumination device (20), in particular with a particularly low installation height, in which moreover the exhaust heat generated by the light sources (2) during operation can escape particularly well, it is proposed that the light module (1) has at least two laterally emitting light emitting diodes (2) as light sources and at least two laterally arranged half-bowl reflectors (6), assigned in each case to at least one of the light emitting diodes (2), as primary optical units.
