Systems and methods for controlling light sources
First Claim
1. A system for controlling a set of light sources, said system comprising:
- a set of light sources;
at least one optical conduit arranged relative to the set of light sources so as to collect excess light from the set of light sources and comprising a periphery configured to pass light from the set of light sources and an interior configured to scatter and route the light to at least one end of the optical conduit;
at least one sensor coupled to the optical conduit and configured to sense light collected by the optical conduit; and
a controller configured to control the emittance of the set of light sources based on the light sensed by the sensor.

Abstract
A system for controlling a set of light sources may include a set of light sources, at least one optical conduit arranged relative to the set of light sources so as to collect excess light from the set of light sources, and at least one sensor coupled to the optical conduit and configured to sense light collected by the optical conduit. The system may also include a controller configured to control the emittance of the set of light sources based on the light sensed by the sensor. A method for controlling a set of light sources may comprise individually varying power supplied to at least some of the light sources in an imperceptible manner, sensing light emitted by a light source for which the power has been varied, and controlling the emittance of the set of light sources based on the sensed light.

16. A control system for controlling a set of light sources, the system comprising:
-
a controller configured to vary the power to at least some of the light sources individually and in an imperceptible manner; an optical conduit comprising a periphery, and an interior, the periphery configured to pass excess light from the set of light sources, the interior configured to scatter and route the light to at least one end of the optical conduit; and at least one sensor at the end of the optical conduit configured to sense the light emitted from a light source for which the power has been varied, wherein the controller is further configured to control the emittance of the set of light sources based on the sensed light. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
