Abstract
An illumination device (100) for a motor vehicle headlight, with an optical body (1) and a plurality of light guiding bodies (2), wherein the light guiding bodies merge into the optical body with their light exit surfaces (2b) in an optical body merging surface (11) opposite an optical body light exit surface (10) of the optical body. The light guiding bodies are arranged such that light exit surfaces of adjacent light guiding bodies have a distance from one another greater than zero resulting respectively in an open space (12) between two adjacent light guiding bodies on the optical body merging surface. The illumination unit (101) further includes an additional optical device (200) that has at least one light entry area (201) and one or more light extraction areas (202). Each light entry area is associated with at least one additional light source (250), and at least some of the light injected by an additional light source into the additional optical device via a light entry area propagates in the additional optical device to the one or more light extraction areas and leaves the additional optical device there, wherein respectively at least one, preferably exactly one, light extr…
