New developments in UV LED process control – using Inline Continuous Automated Dynamic Technology (ICADTechnology)

UV LED Systems consists of numerous UV LED dies, which are bundled into boards (emitter section) that are mounted side by side to make an array of emitters, forming the UV LED Lamp of a certain length. When measuring a conventional UV lamp measuring is done perpendicular to the length of the lamp and this measure is representative of the condition of the lamp as it is one envelope. When measuring perpendicular to a UV LED Lamp this value is only representative of one section of the lamp and does not reveal the conditions of the rest of the lamp. To measure the output of the UV LED lamp, one would have to measure as many times as there are emitter sections – this is not practical. This paper will give an overview of how ICAD-Technology1 is a solution to safe operation of UV LED Lamps in any width while logging always the full output situation. This paper will further show the ICAD-Technology applied to microwave powered medium pressure UV lamps.
