Title:
METHOD OF DETERMINING A LIGHTING SITUATION
Document Type and Number:
WIPO Patent Application WO/2020/083819
Kind Code:
A3
Abstract:
The invention concerns a method of determining a lighting situation with regards to the directionality of the light. According to the method, several photosensitive elements (4), in particular photovoltaic cells (4) or photodiodes, are provided, the maximum photo signal or power yield of which in directional light is achieved at a specific optimum angle of impact of the light onto the light absorbing surface of the photosensitive element (4) and changes or decreases, respectively, with a deviation from said optimum angle. These photosensitive elements (4) are, arranged relative to each other in such a manner that they require different directions of directional light in order to be hit by said directional light in their respective optimum angle of impact, exposed to light (AL, SL), and from the photo signals or power yields of the individual photosensitive elements (4) the lightning situation with regard to the directionality of the light is determined.
