DEMO/Design Clinic of Israel has created a small line of hand-made light fixtures made from old reclaimed plumbing parts, including a spigot that turns the light on and off. These KOZO lamps are designed by David Benatan of Tel Aviv and come in several different styles. The materials are left raw and alive, with a little authentic rust at the joints and the marks from hand tools that were used in the assembly process.

There are a number of interesting new wireless products coming out this year. Here’s one:

leviton-wireless-product

Leviton’s partnership with EnOcean, a developer of wireless building automation technology, has resulted in a new line of self-powered, wireless occupancy sensors, remote switches, wall switches and integrated wireless receivers that automatically turn lights on and off based on occupancy.

Designed as “install and forget” devices, the sensors include an integrated solar cell that harvests power from ambient light in the space, eliminating the need for batteries.

The company says its new products are fully dimmable, priced affordably, have high power factor, turn on instantly and work in place of any traditional incandescent lamp.

One of my biggest complaints about household CFLs is dimming issues, so I’ll definitely be stopping by their booth (#569) to check it out.

The company will also be exhibiting dimmable technology for linear fluorescent luminaires and a wireless lighting control system for commercial building retrofits.

What’s New in Lamps and Ballasts

This year, I have the pleasure of joining Howard Wolfman, recently retired from OSRAM SYLVANIA and now principal of Lumispec Consulting, in presenting the “What’s New in Lamps and Ballasts” seminar at Lightfair International in New York City.

lamps

The seminar (course #L09S22) will be held 4:30-6:00 PM on Wednesday, May 6.

This seminar is a veritable institution at Lightfair, very well attended. It has gotten some criticism for alternately being too generally focused on trends in some years, without enough focus on what’s truly new, and too specifically focused on what’s new in other years, with too much promotion of individual manufacturers.

Howard and I are trying to take a different approach this year. We went to the product managers at a large number of lamp and ballast companies and asked them to report the top innovations in the field over the past 1-2 years. For each innovation, we are identifying 1) what it is, 2) how it compares to the standard offerings in the field, and 3) how it changes design or lighting application. Needless to say, everybody promoted their own companies’ innovations, but we removed all references to manufacturers to satisfy our requirement to make the presentation generic.

Hopefully the result will strike the proper balance and offer the lighting community a satisfying presentation!

We will also be covering LED replacement lamps. While there have been some strides in this area recently, to date the results have been disappointing so we won’t be presenting individual innovations but rather presenting the DOE CALiPER results of testing of a large number of LED A-lamp, candelabra and T8 lamp replacements.

If you’re attending Lightfair, be sure to attend this important event. Click here to see the conference program in a quick-glance format (PDF file).

Researchers Boost Efficiency of Blue OLEDs by 25%

Organic light-emitting diodes (OLEDs) can be used for TVs, computer displays, cell phones and PDAs. These multi-layered devices produce light by running an electrical current through a specially engineered host material into which light-producing phosphorescent molecules are embedded or “doped.”

The technology also holds significant potential as a general area light source, creating the potential for lighting wallpaper and integration of lighting within furniture, equipment and building materials.
The white light envisioned for large-scale applications consists of red, green and blue light. Right now, however, OLEDs emit less light per area than point-source LEDs.

“The weakest link in OLED research is the absence of an efficient, long-lasting blue light to accompany the red and green,” said Pacific Northwest National Laboratory scientist Asanga Padmaperuma. Development of better host materials to manage the flow of electricity through the device could help solve that problem.

Padmaperuma and his colleagues recently announced that they have designed, synthesized and tested new materials that improve the power efficiency of blue OLEDs by at least 25%, bringing us one step closer to the possibilities offered by OLED architectural lighting.

As my colleague Kevin Willmorth has told me numerous times, the Revolution is not about LEDs, it’s about solid-state lighting.

How It’s Made is a TV series consisting of short 24-minute episodes showing how everyday products are made.

While visiting the in-laws today, I caught a segment showing how pole outdoor luminaires are made at a manufacturing plant operated by Canadian manufacturer Lumec.

I found it very interesting, and later found it on YouTube. Here it is below–simply skip ahead to the 4:00 time mark.

ElectricTV.net, operated by NECA, has published a short video about hi-bay T5HO lighting here.

It’s a little basic and attempts to characterize T5HO lighting as “new,” but has interesting visuals and makes a simple case for T5HO lighting. It makes no mention of high-performance T8, however, which is also suitable for many hi-bay lighting applications.

On the lighter side of things, here’s a fun little gadget: the “temperature controlled faucet light,” which activates based on water pressure and changes color based upon water temperature. Blue when the water is cold or simply turned on, and red when the water hits 89 degrees F.

Would probably be a hit with kids and for parties. There’s also a model for taking colorful showers.

San Francisco Demonstrates Advanced Streetlight System

San Francisco Mayor Gavin Newsom and PG&E recently demonstrated streetlights installed on Turk Street (between Taylor and Jones) in the Tenderloin District, networked using Echelon’s LonWorks technology. The new LED streetlights, remotely controlled and monitored, promise to reduce the city’s energy and maintenance costs while improving lighting quality and safety. Streetlights are among a city’s most expensive assets, accounting for almost 40% of its electricity costs, according to Echelon.

The solution featured new LED streetlights from BetaLED embedded with Echelon’s power line signaling technology, allowing communication and control of the streetlights over the existing power lines. Echelon’s i.LON SmartServer is the segment controller, monitoring and controlling the streetlights from anywhere, at anytime over an IP connection. During the demonstration, Mayor Newsom used an iPhone to control and monitor the streetlights. Mayor Newsom also demonstrated a capability unique to LED lights and individual lamp control–the ability to “strobe” the lamps on and off. Tying such a capability to emergency services could add benefits such as enabling response teams to easily locate the site of an incident. A similar pilot project was completed in 2008 on Beale Street in San Francisco and was jointly developed by Echelon, PG&E and BetaLED.

“Networked street lighting systems have been shown to reduce energy use by up to 40%, while improving citizen safety, dramatically lowering maintenance costs, and providing to-the-minute confirmation of lighting performance and availability,” said Anders Axelsson, Echelon’s senior VP of sales and marketing. “Like many energy and cost efficiency solutions, smart, networked streetlighting is not a question of invention, it is a matter of applying today’s technology and products in innovative ways to yield immediate and impressive results.”

San Francisco Mayor Gavin Newsom prepares to control streetlights equipped with Echelon control networking technology using an iPhone over the Web.

“Municipalities and utilities are looking for immediate ways to reduce cost,” said Al Ruud, president of Beta Lighting. “BetaLED provides lower total cost of ownership than traditional sources by reducing energy and maintenance costs. When Echelon’s technology is added, energy and maintenance savings potentials are further enhanced, freeing up funds for other budgetary expenses.”
