Abstract: The invention relates to a device for irradiating a liquid with electromagnetic radiation, in particular for sterilizing an in particular flowing liquid by means of UV radiation (UV reactor), comprising a container having an inlet for receiving the liquid and having an outlet for releasing the liquid from the container, wherein within the container a variable or adjustable irradiation zone is provided for irradiating the liquid with electromagnetic radiation, in particular UV radiation, emitted by a radiation source. In the irradiation zone the liquid is configured in the form of a liquid layer having the layer thickness which extends between the underside of the container and a gas bubble expanding above the liquid layer.

Abstract: A device for sterilising a fluid flowing therethrough by comprises a container having an inlet for receiving the fluid and an outlet for discharging the fluid, a variable or adjustable irradiation zone for irradiating the fluid with UV radiation. The irradiation zone including a gap which extends between two oppositely arranged walls. The distance between the walls, and thus the gap size of the gap, can be changed by at least one wall being movable. For example, the wall is a wall of a displaceable body that is located inside the container or projecting into the container. By adjusting the distance between the walls in the region of the gap, and thus the layer thickness of the fluid flowing through the gap, the efficiency of the operation of the device is optimised with different scattering and absorption properties of the fluid.

The phosphor arrangement (4) comprises at least two different phosphors (R, Y, G) which can be irradiated with the pump radiation (7) and re-emit said pump radiation in a manner such that it is at least partly and in each case differently wavelength-converted. The lighting device (1) is configured to generate, with the aid of the pump laser matrix (2), a controllable distribution of the surface power density of the pump radiation on the phosphors (R, Y, G) of the phosphor arrangement (4).
