Abstract
A glare protection device for a welding protective mask includes an active electro-optical protective filter ( 2 ) and an electronic circuit ( 10 ). An UV-detector (UVD), which serves as an optical sensor, detects the welding light and, via an evaluation circuit ( 10.1 ), generates a signal (sin) for controlling of the protective filter ( 2 ). The signal corresponds to the detected UV intensity. The UV-detector includes a fluorescent layer (F) with an absorption in the UV range and an emission in the long-wave range corresponding to the spectral sensitivity of an assigned Si-photo detector (SD). This results in a simple and safe controlling of the protective filter, which is uninfluenced by the effects of extraneous light.
