Patent ID: 10551019

Abstract:
The present inventions relates to an illumination device, in particular for a vehicle headlight. The device comprises at least one light source, a wavelength converting member converting at least part of the light of the light source to light of a different wavelength, a first and a second light guiding element between the light source and the wavelength converting member, and a reflective member being attached to the wavelength converting member. The second light guiding element is designed to guide the light emitted by the light source and having passed through the first light guiding element to the wavelength converting member and to guide the converted light which has been reflected at the reflective member to the first light guiding element. The first light guiding element comprises at least one first guiding structure guiding the light emitted by the light source to the second light guiding element. The first light guiding element also comprises at least one second guiding structure guiding the converted light which has been passed through the second guiding structure to an outcoupling surface of the first light guiding element. The proposed illumination device allows the use of light sources with high luminance and can be realized in a compact manner.
