WAVELENGTH SENSING LIGHTING SYSTEM AND ASSOCIATED METHODS

Environmental Light Techn...

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 data light;

wherein the controller is configured to receive the data included in the data light using the sensor;
wherein the controller is configured to analyze the data included in the data light and to control the transmission of the
data light from the light source; and

wherein the controller is configured to operate the array to emit an alert upon sensing an event.
