Abstract
An optical assembly and a vehicle lamp are described. The optical assembly has a main exit direction, and includes a light source, a first light guide element and a second light guide element which are arranged in a superposed fashion in the main exit direction. The light source is allocated to the first light guide element, and the first light guide element has a first light in-coupling region and a first light out-coupling surface, the second light guide element has a second light in-coupling surface and a second light out-coupling surface, with the first light out-coupling surface facing the second light in-coupling surface. A light distribution structure is provided on at least a partial segment of at least one of the first light out-coupling surface and the second light in-coupling surface. The vehicle lamp includes the optical assembly described above.
