Anatomy of a Connected PoE lighting Installation

Lighting being omnipresent in a building provides a unique infrastructure to not only gather data pertaining to the space but also share that information with various sub systems in the building to uncover insights that were previously out of reach.

In a connected lighting system, it all starts with a luminaire which houses a smart sensor. Just like the human sensory organs (ears, eyes, nose, skin and tongue) contain receptors that gather information about the surrounding environment, these smart sensors embedded in the luminaires gather data related to the dynamics of their space – be it the analogous occupancy patterns or variability of ambient light and temperature levels. There are numerous possibilities on the type of data being collected by these smart sensors.

But all this data needs to be channeled safely to its right place. A Power over Ethernet (PoE) technology enabled switch acts as interface for this routine. Just like a human heart is necessary to provide energy to all the body tissues and uses an interlined network of blood vessels to pump blood to all
organs and body parts. A PoE technology enabled switch not only provides the necessary energy (power) to the luminaires but it also offers a high bandwidth and secured pathway for the data to be shared and merged with the building’s IT system.

On the other hand, EnvisionGateway acts as a network bridge or area controller providing logical segmentation of PoE and Dynalite devices and handles the routing of all messages in the system, linking multiple subnetworks together. This integration process is similar to the integration that takes place in the gray matter of the brain and spinal cord and is performed by interneurons, wherein many interneurons work together to form complex networks that provide the necessary processing power to
the sensory signals.

Finally the lighting data server is a storage and analytic processing warehouse which upon a specific request from a user, via the front end software, generates an analytical snapshot of the requested information. This behavior is similar to how memories are actively reconstructed from elements scattered throughout various areas of the brain by the encoding process.
