Fixture that provides light incorporating a reconfigurable spectrometer
First Claim
1. A lighting device, comprising:
- a housing;
a light source within the housing configured to output artificial light for general illumination;
a spectrometer, within the housing of the lighting device, configured to detect light and generate signals corresponding to intensities of different wavelengths of the detected light;
a communication interface coupled to a data communication network;
a memory storing spectral reference data and program instructions for analyzing the spectrometer generated signals; and
a processor coupled to the memory, the communication interface, the light source and the spectrometer, wherein the processor, when executing the stored program instructions is configured to perform functions, including functions to;
control operation of the light source;
analyze the signals generated by the spectrometer in response to detecting light in relation to the reference data to detect an environmental substance in an area in which the lighting device is located; and
output, via the communication interface, a report of the detected environmental substance.

Abstract
Disclosed are examples of spectrometer-equipped devices that provide general illumination supplied by artificial or natural light, and that also detect substances in the environment around the device. In some examples, light may be emitted by a spectrometer light source. The spectrometer detects the light from any of a natural light source, artificial general illumination light or light from the spectrometer light source passed, reflected or shifted and regenerated by substances in the air or on a surface in the vicinity of the device. In response, the spectrometer generates signals representative of the spectral power distribution (e.g. intensities of given wavelengths in the optical spectrum) of the detected light. A controller analyzes the spectrometer generated signals and initiates action based on or outputs a report indicating the environmental condition detected by the spectrometer-equipped device.
