Abstract

A lighting device (100) is specified, comprising - a housing (1) having a light exit surface (2), - a light-emitting semiconductor component (10), and - an optical waveguide (20) having a first end face (21), a second end face (22) situated opposite the first end face (21), and a lateral surface (23) connecting the first and second end faces (21, 22), wherein the first and/or the second end face (21, 22) are/is embodied at least in places as a light entrance surface (24), - the light-emitting semiconductor component (10) and the optical waveguide (20) are arranged within the housing (1), - the light-emitting semiconductor component (10) during operation emits light (5) which largely enters into the optical waveguide (20) through the light entrance surface (24) of the optical waveguide (20), - the light (5) in the optical waveguide (20) at least partly emerges through the lateral surface (23) of the optical waveguide (20), and - the light (5) that has emerged through the lateral surface (23) leaves the housing (1) through the light exit surface (2) of the housing (1).
