摘要： 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.

摘要： An illumination device comprises one or several lasers emitting light of a first wavelength or wavelength range, a wavelength converting member converting at least part of the light of the first wavelength or wavelength range into light of a second wavelength or wavelength range, a scanning unit adapted to scan one or several laser beams of said one or several lasers across said wavelength converting member in order to generate an illumination pattern formed at least of the light of the second wavelength or wavelength range, and, optionally, an imaging optics imaging said illumination pattern to the far field. A first light guiding structure is arranged on a light emitting side of said wavelength converting member, said first light guiding structure forming a grid of first light guiding channels. The illumination device can be used as an adaptive headlamp of a vehicle and achieves a high contrast between illuminated and dark regions as well as a high efficiency with a small projection optics.

摘要： A vehicle front lamp that emits light forward includes a first light emitter that emits first emission light having a correlated color temperature of at least 3000 K and at most 7000 K, and a second light emitter that emits second emission light having a correlated color temperature of at least 3000 K and at most 7000 K. The chroma value of the first emission light is lower than the chroma value of the second emission light. The chroma value of each of the first emission light and the second emission light is derived by using the calculation method stipulated in The CIE 1997 Interim Color Appearance Model (Simple Version). The second emission light is emitted far ahead and the first emission light is emitted onto a road surface ahead, when the vehicle front lamp is mounted on a vehicle.
