Abstract (en)
[origin: EP0531557A1] In a device having an electrical measuring voltage source and serving to monitor a lamp unit, in particular in a UV lamp, which is used for irradiating test objects in the testing of magnetic powder or colour penetration, one or more solar cells are used as measuring voltage source on the device itself. In this case, the solar cell must be electrically connected to at least one sensor element. The sensor element is designed to be sensitive in one or more spectral regions. The solar cell can be arranged on the outside of the disc-shaped filter glass averted from the burner. <IMAGE>
