Optical radiation intensity sensor
First Claim
1. A photo radiation intensity sensor comprising a housing having a transparent or translucent portion, and at least one optical sensor element sensitive to radiation, said at least one optical sensor element being arranged for producing output signals which are used for estimating the sun radiation heating impact, wherein the housing includes a chamber containing a diffusive compound that is a potting, which compound is positioned between said housing and said at least one optical sensor element.

Abstract
A radiation intensity directional sensor includes a housing having an opening covered by a transparent or translucent lens element, an array of sensor elements sensitive to radiation, preferably to electromagnetic radiation in the visible and/or infrared range, and a shading element separating at least two of the sensor elements. The shading element at least partly blocks light from impinging directly on one of two sensing elements separated by the shading element. The array of sensor elements is thereby arranged for producing output signals from the at least two separated sensor elements having different amplitudes whereby the difference in amplitude is used for estimating the position of a light source in relation to the sensor housing.

19. A photo radiation intensity directional sensor comprising a housing having a transparent or translucent portion, and at least one sensor element sensitive to radiation, said at least one sensor element being arranged for producing output signals which are used for estimating the sun radiation heating impact, wherein the housing includes a chamber containing a diffusive compound that is a potting, which compound is positioned between said housing and said at least one sensor element,
wherein the compound is flooding the chamber, wherein said sensor includes an array of sensor elements which are arranged to detect both the direction and the intensity of the radiation source, wherein said sensor includes a shading element separating at least two of said sensor elements, whereby said shading element is arranged to prevent exposure of radiation of said at least two sensor elements separated by said shading element to a degree depending of the position of the photo radiation intensity directional sensor in relation to a source of photo radiation, said shading element is thereby arranged for creating differences in output amplitudes from said at least two sensor elements which difference in amplitude is used for estimating the position of the source of radiation, wherein said shading element divides said chamber into at least two sub compartments, each containing one or several sensor elements, and wherein said chamber includes a top region forming part of said at least two sub compartments, where said top region is vertically arranged in relation to said shading element such that said shading element does not prevent photo radiation from impinging on at least a portion of each sub compartment in said top region.
