Abstract

A luminaire for a motor vehicle bodywork includes a light source configured to generate light beams, an optical waveguide configured to forward the light beams, and an optical sheet configured to emit the light beams. The optical sheet is arranged at an angle (γ), which is greater than 0°, with respect to the optical waveguide. A contact is formed between the optical waveguide and the optical sheet. The optical waveguide is configured to transfer the light beams onto the optical sheet. The light beams are guided into the optical sheet with the aid of at least one light guiding element via the contact.
