Abstract
The disclosure relates to a device for providing a multi-colored light beam for a projector. The device comprises a first light source, a second light source, a waveguide element, a beam forming device and a structure element. The waveguide element forms a first waveguide for guiding light from the first light source, a second waveguide for guiding light from the second light source and a coupling out region for coupling light out of the first waveguide and the second waveguide. The beam forming device is designed to form the multi-colored light beam using the light coupled out of the coupling out region. The first light source, the second light source, the waveguide element and the beam forming device are arranged on the structure element.
