Dresden University and German OLED company Novaled are claiming that they have achieved a source efficacy of 90 lumens/W. With this accomplished, researchers say they must now achieve their next breakthrough in increasing service life to make OLEDs competitive with other sources in general lighting applications.

WAC Lighting showcased two innovative OLED fixture prototypes at Lightfair last month, including an OLED mini chandelier and an OLED wall sconce.

wac-oled-chandelier

The OLED Wall Sconce features six color changeable three-inch OLEDs. The mini chandelier uses eight colorful, transparent, one-inch OLEDs, including a panel depicting the WAC Lighting logo. Each OLED draws only 0.18W; each panel is only 2 mm thick.

An OLED features a thin film display technology that began to appear in cell phones and other small-screen applications in early 2000. OLED screens consist of a series of organic layers between two electrical contacts (electrodes). OLEDs are monolithic, with each layer deposited on the other, creating a single unit. Commonly constructed on glass, OLEDs can also be fabricated on plastic and
other flexible films. OLEDs offer bright, colorful images with a wide viewing angle, low power, and high contrast ratio. They can also be made transparent, enabling them to function in heads-up displays and
even as window shades that react to sunlight. OLEDs do not need backlights, and screens can be made ultra thin. OLED’s color, speed, thinness, transparency and flexibility make it a very versatile display technology.

“Many designers and specifiers wanted to know how long it would take for WAC to integrate OLED technology into viable lighting products,” said Shelley Wang, President of WAC Lighting. “They loved the transparency of the panels, the unique quality, the dimmability, the sustainability, and operation without a heat sink. Specifiers touched the panels and were impressed to learn that the fixtures were operating at room temperature. OLED is a flat light source and heat dissipation is more efficient, in contrast to heat accumulation of LED (point-source). The panels are energy efficient, thus they turn energy to light instead of heat.”

photoluminescentLynn Proctor Windle, a contributing editor to Building Operating Management Magazine, wrote an excellent piece on photoluminescent technology as a means of providing emergency lighting in buildings, specially safety signs and path markers. The article is a little dated (March 2005), but clearly summarizes the technology.

Titled “Photoluminescent Technology: Reliable Emergency Lighting in Buildings,” you can find it here.

NEMA’s incandescent and compact fluorescent lamps (CFLs) indices for Q109 declined 2.4% and 4.6% respectively compared to the previous quarter. The incandescent lamp shipments index showed a decline of 16.9% on a year-over-year basis, nearly reaching the all-time low set during the third quarter of 2008. Since the beginning of 2007, the incandescent index has declined in 6 of the 9 previous quarters. CFL shipments declined 14.8% on a year-over-year basis following a gain of 11% during the fourth quarter of 2008.

lamp-index-1

Market penetration of CFLs versus incandescent lamps increased to 23.3% from the fourth quarter 2008 level of 22.5%. Although its share has drifted lower from the record high of 25.3% set back in the third quarter of last year, the ratio of CFLs sold continues to hover around one in every four household lamps.

The review contains some errors in its analysis, but it’s an interesting take and shows what non-lighting people are thinking about some of these advancements. In particular, LEDs still have a very high cool factor with consumers.

I recently wrote an article for the April issue of Electrical Contractor, about some aspects of integrating lighting control and energy management systems.

integration

This is a hot topic because codes now require automatic shutoff of lighting and demand response is going to grow in importance in the future, but EMS traditionally has not done a very good job integrating lighting control, particularly higher-end features such as architectural dimming.

The article features interviews with Synergy Lighting Controls and Square D, and describes the process of and various options for integration.
