The general concept of the Internet of Things (IoT) is expansive and virtually without limit. The basis of the technology is that devices, appliances, building systems, computer networks, vehicles and personal smart devices become connected together in such a way as to exchange and process information or facilitate integrative control functionality. The impact this will have on industries and individuals is potentially profound.

In this LCA column, Kevin Willmorth looks at the Internet of Things and the role lighting is likely to play in it.

Power over Ethernet (PoE) lighting is part of a brave new world. The ascendance of LED fixtures has given rise to some new methods of providing and controlling light in our environments. Since LEDs are low-voltage devices that use direct current, they are a good match with a system that provides low-voltage DC power over Ethernet cables. Guess what? That’s a computer network! For several years, lighting (and computer) companies have been developing the idea of powering LED fixtures from what is essentially a computer network switch. As you might imagine, this gives rise to a host of questions about a variety of issues.

In this LCA column, Steve Mesh takes an in-depth look at power over Ethernet (PoE) systems.
