Abstract
A sensor device is provided for generating an electrical output signal in dependence on the position of a light source in relation to the sensor device. The sensor device has a three-dimensional switch carrier with several adjacent faces oriented in different directions, on which faces at least two sensors are arranged. On the two sides of a central face, there is arranged in each case a face, with an infrared light (IR) photodetector in each case, oriented at an angle to the central face, whereby the faces on which the IR photodetectors are arranged are not directly adjacent to one another.
Claims15
A sensor device for generating an electrical output signal in dependence on position of a light source in relation to the sensor device comprising a three-dimensional switch carrier having a plurality of adjacent faces oriented in different directions and at least two sensors arranged on said faces;
- wherein said plurality of faces comprises a first face, a second face, and a central face between said first and second faces so that said first and second faces are not directly adjacent to one another;
- wherein said at least two sensors comprises a first infrared light photodetector arranged on said first face and a second infrared light photodetector arranged on said second face, said first and second infrared photodetectors being oriented at an angle to said central face;
- and
- wherein a visible light photodetector is arranged on said central face.
