Embodiment Construction

[0021] FIG. 1 shows a schematic illustration of a sensor device 10 according to the invention. It comprises a light guide 12 , a first receiver 14 , a second receiver 16 and a third receiver 18 . The receiver 14 has a photosensitive element 20 which is arranged on the optical axis of a focusing device 22 . Focusing device 20 is capable of at least partially deflecting and / or focusing radiation impinging on light guide 12 from at least one predetermined direction onto element 20 . The photosensitive element 20 is designed, for example, as a CCD element or as a simple photodiode, for example from semiconductor components.

[0022] The focusing device 22 basically has two sections, namely a first section 24, which is substantially cylindrical, and a focusing second section 26, which is parabolic and substantially limited towards the bottom of the photosensitive element 20. A focusing device 22 or a cylindrical section 24 is provided. The focusing section 26 focuses the radiati...

Abstract

The invention relates to a sensor device (10), especially for a motor vehicle, said device comprising an optical waveguide body (12), a first receiver (22), and a second receiver (22a). Said receivers detect the light radiation, especially sun radiation, radiating through the optical waveguide body (12), and emit signals to a control means (30). Said control means (30) are used to control a device (32) influencing the air-conditioning.

Description

technical background [0001] The invention relates to a sensor arrangement, in particular for a motor vehicle, according to the preamble of the independent claim. [0002] A large number of sensor devices are known, especially for motor vehicles, which are able to detect light radiation, for example sunlight, in the motor vehicle. These devices have a light guide through which light is directed to a plurality of sensor elements. These sensor devices are used to control the lighting of the vehicle, so that the lighting of the vehicle is switched on when the vehicle enters a tunnel or when the brightness decreases due to twilight. [0003] In addition, sensor devices are known which detect the direction of sunlight in order to control various further devices of the motor vehicle. These sensor devices have sensor arrays or quadrant photodiodes, but they are expensive and not accurate enough for direction detection. Contents of the invention [0004] A sensor device according ...
