摘要

Electrical or electronic switching arrangement (100) comprises a detector unit (10) with a starting voltage (Vaus) as a measure for the angle of incidence (Li) on the detector unit and a comparator unit (20) connected to the detector unit to compare the starting voltage with a reference voltage (Vref). Preferably the detector unit has a bipolar transistor, especially a pnp transistor. The starting voltage of the detector unit depends on the wavelength and/or the intensity of the incidence light. The chip arrangement is protected using a dielectric cover made from epoxy resin, silicon nitrite or silicon dioxide.
