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.

Claims

1. A semantic lighting system for delivering a dynamic, fully user personalized, and subject and task specific lighting profile to a subject, comprising:

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 plus characteristics of a subject to be illuminated;

a control unit for allowing a user to program the lighting system; and

a processing unit for analyzing data from said sensor pod and control unit and for constructing an optimal lighting profile in accordance therewith;

whereby said lighting system generates light in accordance with said lighting profile that is optimized in spectrum, intensity, color, contrast, temperature, angle, and focus for any given user, environment, subject and task.

2. The semantic lighting system according to claim 1, wherein said sensor pod additionally senses characteristics of a human user for constructing said optimal lighting profile.

3. The semantic lighting system according to claim 2, wherein said human user characteristics include eye characteristics.

4. The semantic lighting system according to claim 2, wherein said human user characteristics include a relative position of the user with respect to the source of light.

5. A method for delivering a dynamic and task specific lighting profile to a subject, comprising the steps of:

first analyzing properties of a subject, inclusive of nature, dimensions, shape, texture, contrast, reflectivity, transparence and temperature;

second analyzing properties of environment, inclusive of existing illumination;

controlling a lighting source in accordance with said first analysis and second analysis, and with one or more variables chosen from among the group including spectrum, intensity, color, contrast, temperature, angle, focus, and data;

controlling said lighting source dynamically over time to adapt to changing environments and changing task requirements.

6. The method according to claim 5, further comprising a third step of analyzing characteristics of a human user, said step of controlling a lighting source being in accordance with said first analysis, second analysis and third analysis for constructing said optimal lighting profile.

7. The method according to claim 6, wherein said characteristics of a human user include eye characteristics.

8. The method according to claim 6, wherein said characteristics of a human user include a relative position of the user with respect to the source of light.
