Power-over-Ethernet meets LED lighting: Application note
The application note also explains how powering and controlling LED lights over a PoE network creates the opportunity to use the LED lights in new and novel ways. Examples are given.
In its introduction, the Note revisits how Power-over-Ethernet (PoE) idelivers power over the same cable that delivers the Ethernet data. This reduces the number of cables that must be laid to install a network and power the devices connected to it. It also makes it easier to maintain and adjust the access ports on the network to meet changing requirements than with traditional wiring. The PoE standard was originally developed to meet the needs of IT services and is appropriate for a wide range of network connected devices including IP telephony, IP security cameras, wireless access points, modems, switches, and other networked products.
Designers and facility managers (the note continues) continue to find new ways to reap the benefits of using PoE networks by connecting devices that were previously never associated with networks such as LED lighting. The nature of LED lighting lends itself to naturally leverage the strengths of a PoE installation. The Note goes on to explore how and why LED lighting and PoE networks are a perfect match for each other, beginning with the elements that make up a PoE network installation.
