Abstract
A lighting system includes a light source included in an array of light sources to emit illuminating light, a sensor Included in the array to sense environmental light from an environment, and a controller operatively connected to the sensor and the light source 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 is transmittable in a data light defined by a data wavelength defined relative to the illuminating light. The controller receives the data included in the data light using the sensor and analyzes the data included in the data light and to control the transmission of the data light from the light source. The plurality of light sources emit the illuminating light in a plurality of directions. The sensor receives the environmental light from a plurality of directions.
