H.E. Williams, Inc.
has been a traditional hard goods manufacturer for close to 100 years. “Turning sheet steel and aluminum into these nice, highly finished lighting products,” says Randy Jones, Engineering Manager at Williams.
But for years, Williams has also been putting various types of control devices — whether a power supply or occupancy sensor—into fixtures, as a way to bring controllability to the space and create additional energy savings. That was good for the time being, but their engineers and product developers also saw the next big innovation coming down the pike: how power over ethernet and lighting could peacefully coexist.
“The reason we’ve jumped on this train with PoE is because it’s low voltage. LED is low voltage by its nature, and DC, so it’s kind of a natural fit electrically. Plus, the push for smart buildings–that drumbeat is getting louder and louder.”
They turn light into electricity or vice versa: the inkjet inks developed by researchers at the Fraunhofer IAP can be printed on solid substrates as well as on flexible foils. In effect, solar cells and organic displays can be produced fast and cost-effectively.
