A radiation-emitting apparatus for emitting a variable electromagnetic secondary radiation (6) in an emission direction (10) comprises in particular at least one radiation-emitting component (1) which emits during operation an electromagnetic primary radiation (4), a reflector (2) which is arranged in the beam path of the radiation-emitting component (1) and has a first wavelength conversion substance (21) for the at least partial conversion of the primary radiation (4) into electromagnetic conversion radiation (5), and an aperture (3) which is variable in terms of its orientation relative to the radiation-emitting component (1) and to the reflector (2), wherein, by way of changing the orientation of the aperture (3), the secondary radiation (6) is variable by changing that proportion (41) of the primary radiation (4) which is emitted by the radiation-emitting component (1) onto the first wavelength conversion substance (21), and by changing the emitted conversion radiation (5). |
