Autonomous light power density detectors

A method comprising:

• controlling a light source to change an intensity of the light emitted by the light source;
• measuring a power used to emit the light;
• detecting a room boundary and a position of a proximate device;
• communicating with the proximate device to transmit measured data to the proximate device, and to receive proximate device data from the proximate device;
• calculating a lighting power density based on the proximate device data and the measured data;
• and
• adjusting the power used to emit the light based on the lighting power density.

A non-transitory machine-readable storage medium encoded with instructions executable by a processor, the non-transitory machine-readable storage medium comprising:

• instructions to control a light source to change an intensity of the light emitted by the light source;
• instructions to measure a power used to emit the light;
• instructions to detect a room boundary and a position of a proximate device;
• instructions to communicate with the proximate device to transmit measured data to the proximate device, and to receive proximate device data from the proximate device;
• instructions to calculate a lighting power density based on the proximate device data and the measured data;
• and
• instructions to adjust the power used to emit the light based on the lighting power density.
