Abstract:
A device for emitting a first and a second electromagnetic radiation (13, 23, 53) via a radiation coupling-out surface (5) along a device beam path. A first radiation-emitting arrangement (1) has at least one first radiation-emitting component (10) which emits the first electromagnetic radiation (13). A second radiation-emitting arrangement (2) has at least one second radiation-emitting component (20) which emits the second electromagnetic radiation (23). Furthermore, the device has a radiation-directing element (3), wherein the radiation coupling-out surface (5) is arranged in the beam path of the second radiation-emitting arrangement (2) and the radiation-directing element (3) directs the first electromagnetic radiation (13) to the radiation coupling-out surface (5).
