Organic Response

The moment a Sensor Node detects occupancy, it switches on its luminaire to a predetermined level. It simultaneously communicates with its immediate neighbours, using proximity limited wireless infrared, telling them it can see someone.

On receipt of this signal (and even though it may not itself detect anyone), the neighbouring Sensor Node switches its luminaire on to a specified level (e.g. 80% brightness), and simultaneously relays a signal to its own neighbours, telling them that one of its immediate neighbours can see someone.

This propogates rapidly throughout the floor with each Sensor Node receiving a signal indicating how close someone is to it, and emitting a pre-programmed light level based on that occupancy information, after adjusting for ambient light. Simultaneously, it increments the signal by one level and re-transmits it.

This results in comfortable lighting conditions around occupants, lower light levels in areas adjacent to them, but no wasted lighting of unoccupied or naturally lit areas.
A simple smartphone app allows individual luminaire brightness to be trimmed to optimal levels for specific tasks or the local environment. Alternatively, relay configuration, using the infrared communication described above, allows a whole floor to be configured with the press of a few buttons on the app.
