Abstract
Official abstract text for this publication.
A system for determining light conditions in a space of interest and to control a device thereon includes a light sensor arranged to detect light entering a sub-volume of the space of interest to provide measurement data corresponding to at least an intensity and direction distribution of light entering the sub-volume: a data processor configured to communicate with the light sensor to receive the measurement data, the data processor configured with a computational model to provide a calculated distribution of light based on the measurement date from the sub-volume of the space of interest; and a control system configured to communicate with the data processor to receive the calculated distribution of light and provide control signals based on the calculated distribution of light.
First claim
Opening claim text (preview).
We claim: 1 . A luminous-distribution sensor, comprising: a front panel defining an aperture therethrough; an optical core having a concave surface and arranged behind said front panel so that light that passes through said aperture would impinge upon said concave surface; and a plurality of light-sensing elements distributed across said concave surface, wherein said plurality of light-sensing elements provide intensity and direction of light along a corresponding plurality of light-ray paths to provide a measured luminous distribution. 2 . The luminous-distribution sensor according to claim 1 , wherein said concave surface is a semi-spherical surface. 3 . The luminous-distribution sensor according to claim 2 , wherein said plurality of light-sensing elements are arranged in a pattern across said concave surface corresponding to a Klems basis.
