1. A lighting system comprising:

  • a light source to emit illuminating light;

    a sensor to sense environmental light from an environment;

    a controller operatively connected to the sensor to analyze the environmental light that is sensed and the light source to control emitting the illuminating light;

    wherein the controller analyzes the environmental light to detect or generate data relating to a condition of the environment, the data being transmittable in data light;

    wherein the controller receives the data included in the data light using the sensor;

    wherein the controller analyzes the data included in the data light;

    wherein the controller controls transmitting the data light from the light source;

    wherein the light source is included in an array to be selectively enabled and disabled by the controller;

    wherein the sensor is included in the array;

    wherein the array includes a plurality of light sources;

    wherein the plurality of light sources is selectively operable substantially simultaneously;

    wherein the plurality of light sources is selectively operable individually;

    wherein the plurality of light sources selectively emits the illuminating light in a plurality of directions;

    wherein the sensor receives the environmental light from the plurality of directionswherein the light source and the sensor are included as a light emitting semiconductor device; and

    wherein the light emitting semiconductor device is selectively operable between a sensing operation and an emitting operation, the sensing operation being defined by the light source sensing the environmental light, and the emitting operation being defined by the light source emitting the illuminating light.
