摘要： The present disclosure enables lighting performance which appears as if there are more light sources than the actual number of light sources, and reduces brightness unevenness. A vehicular light-emitting device includes a plurality of light-emitting units, each of which includes an LED part and a lens configured to diffuse and emit the light received from the LED part, the plurality of light-emitting units being arranged side by side. The plurality of light-emitting units are arranged so that one or more brightness peak values exist between adjacent light-emitting units. Moreover, the light emitted from the lenses of the light-emitting units has a plurality of brightness peaks with respect to the spreading direction of the light, and the arrangement interval of the plurality of light-emitting units is set so that the plurality of brightness peaks of the light emitted from the plurality of light-emitting units are aligned at substantially equal intervals.

摘要： A light module is particularly suited for use in a lighting device for a motor vehicle. The light module has at least one extensive light body and at least one illuminant, the light rays of which are able to exit, or exit, to the outer side via a light-exit area that is surrounded by side areas of the light body. At least one part of the side areas and a back area lying opposite the light-exit area are covered by a reflective or diffusely back-scattering cover. The cover is formed by a frame-like component with a back wall. A side wall of the frame-like component has an opening. The light body is able to be laterally slid into, or is laterally slid into, the frame-like component through the opening. The at least one illuminant is disposed on the side wall with the opening of the frame-like component.
