Abstract

An arrangement for irradiating a surface includes a radiation source configured to emit ultraviolet radiation, a reflector for directional radiation of the ultraviolet radiation onto the surface, and a control device. A dose of the ultraviolet radiation required for sterilizing the surface and/or a dose already administered is settable and/or determinable by the control device.

Claims (36)

1. An arrangement for irradiating a surface, comprising:

a radiation source configured to emit ultraviolet radiation;

a reflector for directional radiation of the ultraviolet radiation onto the surface;

a control device, wherein a dose of the ultraviolet radiation required for sterilizing the surface and/or a dose already administered is settable and/or determinable by the control device; and

a first drive and a second drive, wherein each of the first drive and the second drive has a respective friction wheel which abuts an outer surface of the reflector such that the reflector is rotatable around a first axis by the first drive and is rotatable around a second axis by the second drive.

2. The arrangement according to claim 1 , wherein the reflector has a spherical section or semi-sphere on an outer side of the reflector.

3. The arrangement according to claim 1 , wherein the reflector is formed on an inner side of the reflector for distributing the ultraviolet radiation as uniformly as possible on the surface.

4. The arrangement according to claim 1 , wherein an inner side of the reflector is configured as an elliptical paraboloid.

5. An arrangement for irradiating a surface, comprising:

a radiation source configured to emit ultraviolet radiation;

a reflector for directional radiation of the ultraviolet radiation onto the surface; and

a control device, wherein a dose of the ultraviolet radiation required for sterilizing the surface and/or a dose already administered is settable and/or determinable by the control device;

wherein the reflector is configured on an inner side for concentrating the ultraviolet radiation on an area of the surface;

wherein the inner side of the reflector is configured as a free-form reflector comprising two or more hollow forms which focus at least a major part of the ultraviolet radiation onto a common focal point.

6. The arrangement according to claim 1 further comprising an optical system for aligning the ultraviolet radiation disposed in a beam path of the ultraviolet radiation emerging from the reflector.

7. The arrangement according to claim 1 , wherein, by the control device, a time period of an effect of the ultraviolet radiation is adaptable to a radiation power varying as a result of an alignment by the first drive and the second drive and a distance between the reflector and the surface.

8. The arrangement according to claim 7 , wherein the control device is configured to traverse the surface in a grid-like manner such that all relevant areas are irradiated with a lethal dose sufficient for germs in biofilms.

9. An arrangement for irradiating a surface, comprising:

a radiation source configured to emit ultraviolet radiation;

a reflector for directional radiation of the ultraviolet radiation onto the surface; and

a control device, wherein a dose of the ultraviolet radiation required for sterilizing the surface and/or a dose already administered is settable and/or determinable by the control device;

wherein the control device is configured to store a dose already administered in an event of an interruption of radiation of the ultraviolet radiation and to continue the radiation after the interruption until an intended dose is reached.

10. A vehicle, comprising:

a vehicle interior; and

an arrangement for irradiating a surface in the vehicle interior, wherein the arrangement comprises:

a radiation source configured to emit ultraviolet radiation;

a reflector for directional radiation of the ultraviolet radiation onto the surface; and

a control device, wherein a dose of the ultraviolet radiation required for sterilizing the surface and/or a dose already administered is settable and/or determinable by the control device;

wherein a negative pressure or a vacuum is generatable in the vehicle interior during operation of the arrangement.

11. A vehicle, comprising:

a vehicle interior;

an arrangement for irradiating a surface in the vehicle interior, wherein the arrangement comprises:

a radiation source configured to emit ultraviolet radiation;

a reflector for directional radiation of the ultraviolet radiation onto the surface; and

a control device, wherein a dose of the ultraviolet radiation required for sterilizing the surface and/or a dose already administered is settable and/or determinable by the control device; and

a living being detector and an emergency stop button, wherein the vehicle interior is ventilated when a living being is detected or the emergency stop button is actuated.
