Multi-channel light sensor
First Claim
1. Multi-channel light sensor (2) adapted to detect a plurality of different light intensities comprisinga) a fragmented lens (3), andb) a camera sensor (5) adapted to detect visible light;
- c) wherein the fragmented lens (3) comprises lens elements (4); and
d) wherein each lens element (4) is adapted to direct visible light from a spatial area onto the camera sensor (5) such that the light intensities of different spatial areas are spatially resolved on the camera sensor (5),wherein the lens elements each have a different optical axis, so that they direct the light from different spatial areas to different corresponding areas of the camera sensor,wherein the fragmented lens (3) is a Fresnel lens, and wherein the lens elements (4) correspond to different sections of the Fresnel lens.

Abstract
The present invention provides a multi-channel light sensor comprising a fragmented lens and a camera sensor; wherein the fragmented lens comprises lens elements; and wherein each lens element comprises an own optical axis and is adapted to direct light from a spatial area onto the camera sensor such that the light intensities of different spatial areas are spatially resolved on the camera sensor. Furthermore, a system is provided, which comprises at least one such multi-channel light sensor, at least one lighting device, and a light management device; wherein the light management device is adapted to receive the light intensities of the different spatial areas from the multi-channel light sensor; and wherein the light management device is adapted to control the at least one lighting device on the basis of the light intensities of the different spatial areas.
