Semantic light

Abstract

A lighting system for delivering a dynamic, fully customized, and automatic illumination to a subject. The lighting system comprises a programmable light unit for emitting a programmed pattern and spectra of illumination, a sensor pod comprising an array of sensors for detecting ambient lighting conditions and subject characteristics, a control unit for allowing a user to program the lighting system, and a processing unit for analyzing data from the sensor pod and control unit to construct an optimal lighting profile in accordance therewith. The lighting system generates light in accordance with the lighting profile which is fully optimized in spectrum, intensity, color, contrast, temperature, angle, and focus for any given environment, subject and task.
