Abstract: A device for applying radiation to a target is provided. The device includes a radiation emitter to emit electromagnetic radiation having a peak emission wavelength in the range from 10 nm-1 mm, and a first reflector that extends in a length direction with a concave cross section. The first reflector defines a cavity area having a perimeter, and includes an inward facing reflective border for at least 50% of the perimeter of the cavity area. Radiation is provided to the cavity area with an intensity distribution I and a maximum intensity Imax. The cavity area includes a focal area defined by all points at which a normalized intensity I/Imax is greater than 0.2. A width of the focal area is 0.0001-0.5 times a width of the cavity area.

Abstract: A multi-beam LED emitter unit is provided that combines multiple LED emitter modules, each equipped with at least one LED for emission of UV radiation of a wavelength below 430 nm or IR radiation of a wavelength above 780 nm. Each LED emitter module includes a housing equipped with a radiation exit window and is designed as an insertion assembly for a docking station. The docking station includes at least one connecting means for establishing a form-fitting mechanical connection to the housing and one plug element of an electrical plug connection. The housing includes a rear side including a mechanical counterpart corresponding to the connecting means and a counter element corresponding to the plug element. The connecting means and the corresponding mechanical counterpart are arranged such that establishing the form-fitting mechanical connection is associated with establishing an electrical connection between plug element and counter element.

Abstract: The invention relates to a radiation source including: an illuminant; a first optical element; and a sensor. The sensor is designed appropriately and is connected to the first optical element appropriately such that the sensor can be used to determine a change of a parameter of the first optical element over time, whereby the parameter affects an optical property of the radiation source. Moreover, the invention relates to a method for the producing a product involving the provision of a radiation source according to the invention as well as to a use of the radiation source to increase the efficiency of conversions or changes of state of educts to products.
