LEDs fight for the Edison socket

Alix Paultre, Editorial Director, PSD

Unfortunately technology development is guided (and often blocked) by the infrastructure issues of the previous technology(s). Nowhere is this more apparent than in solid state lighting, especially that driven by LEDs. There is an old story in technology development that asks about the dimensions of the sp

LEDs: from emerging technology to a commodity at the speed of light.

Kevin Parmenter, Contributing Editor

In my career I have seen few things go from emerging to a sea change as fast as the LED lighting market. LED lighting has gone from emerging technology to mainstream commodity very rapidly, and there are yet few standards. Every application usually needs something different, as every customer wants something a

PoE is perfect for LED lighting

Alec Makdessian and Thong Huynh, Maxim Integrated

Power-over-Ethernet (PoE) is a technology used in wired Ethernet local area networks (LANs) that delivers 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 an
