Abstract
An illumination device for a motor vehicle includes a light source constructed of a number of semiconductor diodes, and an optical device for generating a predefined light distribution from the light of the light source. The optical device is arranged in a housing. The illumination device is characterized in that the light source is rigidly connected to the housing. At least one optical waveguide is provided for guiding the light of the light source to the optical device.
Claims19
An illumination device for a motor vehicle, comprising:
- a housing;
- a light source constructed of a number of semiconductor diodes and having a light emission end located within the housing or at an aperture in a wall of the housing;
- an optical device separate from and arranged in the housing and arranged to be movable relative to the housing and to the light source by a rotational element extending between the optical device and an immediately adjacent inner wall of the housing, the optical device being designed to generate a predefined light distribution from light of the light source;
- and
- at least one flexible optical waveguide located entirely within the housing between the light source and the optical device, the at least one flexible optical waveguide being designed to receive in the housing and guide the light of the light source to the optical device,
- wherein
- the light source is rigidly connected to a heat sink outside of the housing, and
- an optical device end of the at least one flexible optical waveguide is located at the optical device in a manner such that there is no relative movement between the optical device and the optical device end when the optical device moves relative to the housing.
