Wavelength sensing lighting system and associated methods
First Claim
1. A lighting system comprising:
- a light source included in an array to emit illuminating light, the array including a plurality of light sources;
a sensor included in the array configured to sense environmental light from an environment; and
a controller operatively connected to each of the sensor and the light source and configured to analyze the environmental light sensed by the sensor to at least one of detect and generate data relating to a condition of the environment, the data being transmittable in a transmitted data light;
wherein the controller is configured to receive data included in a received data light using the sensor; and
wherein the controller is configured to analyze the data included in the received data light and to control the transmission of the data light from the light source;
wherein the controller is configured to analyze the environmental light by measuring a drive voltage of the light source, determining a difference between a measured voltage across the light source and the drive voltage, and performing time-domain matching of the measured voltage and the environmental light using cross-correlation.
