Intelligent solid state lighting
First Claim
1. A lighting system for humanly visible light illumination, the system comprising:
- a light fixture, comprising;
(a) a solid state light source; and
(b) a detector of a type and located so as to sense a condition external to the light fixture, the detector being configured to output a signal responsive to the sensed condition;
a controller, comprising;
(i) a processor coupled to respond to the condition responsive signal of the sensor;
(ii) a memory accessible to the processor; and
(iii) a program stored in the memory for execution by the processor, for controlling at least one function of the processor responsive to the condition responsive signal of the sensor; and
a communication interface accessible by the controller, configured to enable the controller to transmit a message containing information resulting from the at least one function of the processor responsive to the condition responsive signal of the sensor through a communications network.

Abstract
A light fixture, using one or more solid state light emitting elements utilizes a diffusely reflect chamber to provide a virtual source of uniform output light, at an aperture or at a downstream optical processing element of the system. Systems disclosed herein also include a detector, which detects electromagnetic energy from the area intended to be illuminated by the system, of a wavelength absent from a spectrum of the combined light system output. A system controller is responsive to the signal from the detector. The controller typically may control one or more aspects of operation of the solid state light emitter(s), such as system ON-OFF state or system output intensity or color. Examples are also discussed that use the detection signal for other purposes, e.g. to capture data that may be carried on electromagnetic energy of the wavelength sensed by the detector.
