Irradiation unit for irradiating an object with ultra violet or visible light, comprises one or more light diodes arranged in parallel in two or more groups

摘要

An irradiation unit for irradiating an object with UV or visible radiation, comprises one or more light diodes (3) for producing the radiation. The diodes are arranged in such a way so as to dry, harden and/or sterilize the object being irradiated. The diodes are located on a flat, flexible carrier element, and are arranged so they are parallel, in two or more groups. An irradiation unit for irradiating an object with UV or visible radiation, comprises one or more light diodes (3) for producing the radiation. The diodes are arranged in such a way so as to dry, harden and/or sterilize the object being irradiated. The diodes are located on a flat, flexible carrier element, and are arranged so they are parallel, in two or more groups. A Fresnel lens is located between the diodes and the object in order to bundle the light. The radiation is focussed onto a focussing point , and the diodes can deliver pulses of radiation. The object is located in an inert atmosphere.
