Light sensor arrangement for sensor unit of ambient light sensor of motor vehicle, has light conductor element for guiding light beam bundles coupled at carrier element to output areas such that bundles are directed to sensor elements

摘要

The arrangement (10) has a detection area (15) with two sensor elements (19, 21) arranged at a distance to each other for detecting intensity of light beam bundles (L1, L2). A light conductor element (14) guides the light beam bundles coupled at a carrier element (7) at the detection area to output areas (18, 20) such that the light beam bundles are directed to the sensor elements respectively. The light conductor element has a reflection surface at one of the output areas for reflecting one of the light beam bundles to the other output area.
