Abstract
A light module (1) which comprises preferably at least three laser diodes (2a, 2b, 2c) that emit light in a visible wavelength range, a respective collimating device (3a, 3b, 3c) per laser diode, a beam combination device (4) for combining the emitted light of the individual laser diodes (2a, 2b, 2c), a beam-shaping device (5) for shaping the combined beam, and at least one emitter (6) for generating non-visible light, in particular an IR laser diode. The emitter (6) is arranged in such a way that the emitted non-visible light is not guided through at least one of the beam combination device (4) or the beam-shaping device (5).
