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).

Abstract: An illuminated bottle closure with a dispenser function for a hollow body is provided. The illuminated bottle closure may include at least one light source, wherein the at least one light source is configured to be switched on for a predetermined time when the dispenser is actuated and illuminates at least one of the liquid dispensed and the liquid contained in the dispenser.

Abstract: A cooling apparatus with a cooling space which is especially suited for storing perishable foods is given. In the cooling apparatus there is a UV radiation source which is suited to emitting electromagnetic radiation from the ultraviolet region, and in its operation the cooling space is irradiated with this radiation. Via the electromagnetic radiation it is fundamentally possible to kill microorganisms such as bacteria and molds and thus to disinfect the refrigerator and the free surfaces contained in the cooling space as well as the air of the cooling space.
