Methods and Apparatus for Sensing Light Output and Controlling Light Output

A method of directing light output of LEDs in a LED network, comprising:

• associating directional information and intensity information of a plurality of light-generating LEDs with a plurality of light-sensing nodes;
• associating a directional parameter with each of said light-sensing nodes;
• monitoring a light intensity at each of said light-sensing nodes;
• detecting a blocked condition at a blocked node of said light-sensing nodes when said light intensity is below a threshold level at said blocked node;
• activating, in response to said blocked condition, at least one of said light-generating LEDs associated with said blocked node that has said directional information corresponding to said directional parameter of said blocked node.

A network of LEDs, comprising:

• a plurality of networked LEDs;
• said networked LEDs including a first LED configured to selectively generate a light output therefrom and a second LED configured to selectively sense a light intensity level thereat;
• wherein said light output of said first LED affects said light intensity at said second LED when no obstructions are present therebetween;
• wherein said first LED is illuminating in the direction of said second LED in response to said second LED sensing said light intensity level thereat below a threshold value.
