Osram Opens OLED Pilot-production Facility in Germany

02 Sep

Citing an initial investment of 20 million Euros, Osram announced that it has opened a pilot-production line for the manufacture of organic LEDs in Regensburg, Germany.

Osram AG (Munich, Germany), the lighting subsidiary of Siemens AG, is celebrating the opening of a pilot-line manufacturing plant for organic light-emitting diodes (OLEDs). The facility in Regensburg West, which currently employs 220 people, required an investment of 20 million Euros ($28.9 million).

“Today Regensburg is sending out an important message for the high-tech location of Germany and the safeguarding of high-quality jobs,” said Wolfgang Dehen, chairman of the managing board of Osram AG. Annette Schavan, the German Federal Minister for Education and Research said “The inauguration of this OLED production plant in Regensburg proves Germany’s leading position in the introduction of this future technology.”

The new pilot-production line enables Osram to manufacture transparent OLED-panels. One goal is to double the brightness of the OLEDs, while improving efficiency and further strengthening panel durability. In the last stage of expansion, Osram expects to reduce OLED manufacturing costs by 90 percent. “Two years ago, we were the first company to offer serial OLED-products on the market. The new production is a major leap on the way to widespread use,” said Martin Goetzeler, member of the managing board and COO of Osram AG.

Significant investment

Osram is reportedly the only company with production sites for both (inorganic) LEDs and OLEDs in Europe. Osram currently dedicates two-thirds of its research and development (R&D) expenditures to LEDs and OLEDs. In the past five years, the company has invested approximately 50 million Euros ($72.25 million) in R&D to OLEDs. The company’s portfolio includes OLED panels and modules as well as complete luminaires.

Germany’s Federal Ministry of Education and Research (BABF) has played a critical role in the country’s development of OLED technology through the OLED 2015 initiative. In the second phase of the initiative, four companies, Osram Opto Semiconductors, Philips, Aixtron and BASF, received a commitment for funding from the BABF to be used toward developing innovative material and component architectures as well as new production machines for lighting solutions with highly-efficient OLEDs. In this second-phase TOPAS 2012 program, which stands for Thousand-lumen Organic Phosphorescent devices for Applications in lighting Systems, Osram Opto Semiconductors has been focused on developing transparent OLED solutions with a size of 1 square meter.

While inorganic LEDs use semiconductors to convert electricity into light, OLED panels generate a luminous surface based on a very thin stack of organic semiconductor layers that have been evaporated onto a thin substrate (400 nm total thickness). When switched off, the OLED can either display a mirroring effect, be neutrally white or transparent, depending on the basic material.

Cree Announces Blue LED and Remote-phosphor Licensing Program

10 Aug

Royal Blue XLamp XT-E LED targets remote-phosphor SSL applications, and Cree is offering licenses for its remote phosphor-technology for ready usage by lamp and luminaire vendors.

Cree announced the new XLamp XT-E Royal Blue LED that delivers 525 mW of radiant flux, and targets remote-phosphor solid-state-lighting (SSL) applications. The company will match that LED with a remote-phosphor patent licensing program that will allow lamp and luminaire designers to accelerate the SSL design cycle.

Cree says that the new LED offers “category-leading brightness” along with 2.5-nm bins that it asserts are the industry’s tightest. Mike Watson, Cree senior director of marketing, LED components, said, “The new Cree XLamp XT-E Royal Blue LED outperforms the competition in both elements enabling our customers to design high-performance and low-cost systems.”

The LED is based on Cree’s Direct Attach packaging technology that relies on bond pads on the bottom side of the emitter and what the company calls a “eutectic die-attach process” that eliminates bond wires and uses a chemical compound for the bond. That design yields the 525 mW of flux at 350-mA drive current and 85° C operating temperature.

Remote-phosphor technology

Remote-phosphor SSL designs typically utilize a blue emitter — generally considered to be the color that delivers maximum efficacy. The phosphor that generates the white light is coated on a secondary optic or diffuser. Proponents believe such designs deliver better efficacy than do phosphor-converted LEDs. Phosphor-specialist Intematix, for one example, maintains that its remote-phosphor technology can deliver a 30% efficiency advantage.

There are certainly notable examples of remote-phosphor products that achieve superior efficacy. For example, the Philips lamp that was announced as the US Department of Energy (DOE) L Prize winner last week uses a remote phosphor.

Patent licensing

Cree hopes to help design teams working on remote-phosphor lamps and systems via the patent licensing program. Cree says that a license will allow access to patents that are fundamental to the combination of a blue emitter and a phosphor-coated optical element.

Early this year, Cree announced what is essentially a reference design of a 60W-equivalent LED-based lamp that uses remote-phosphor technology and that according to Cree would meet Energy Star requirements. At the time of that announcement, Cree said that the design relied on patented remote-phosphor technology. It’s not clear if that same technology is included in the new licensing program.

Other royal-blue LEDs

Cree is not the first company to announce a royal-blue LED targeted at remote-phosphor lamps and luminaires. Philips made a similar announcement back in May of a royal-blue LED in the Luxeon ES family of components.

Coincidentally, or not, both the Cree and Philips announcements were lacking a measurement of light output in the more traditional units of lumens (lm). Cree chose to specify its product in the wattage unit that defines the radiometric power or radiant flux of the output.

Originally Philips simply provided a specification of wall plug efficiency for its LED. Subsequently the company has published a data sheet with a rating of 500 mW at 350 mA.


Osram Opto Delivers Small LED for Linear Lighting

01 Jun

Small Duris E 3 LEDs with wide beam pattern are optimized for linear and planar SSL applications where people don’t perceive the individual point light sources.

Osram Opto Semiconductors has announced a new sub-1W LED that specifically targets linear and planar lighting. The company intends for the Duris E 3 LEDs to be placed closely together in solid-state-lighting (SSL) luminaires and linear retrofit tubes so that people perceive a uniform source of light rather than individual point sources.

The target application is both LED-based retrofit tubes for T5 and T8 linear fluorescent tubes, and purpose-built SSL fixtures that will be used in place of fluorescent-tube troffers. Osram identified applications in open-floor-plan offices, production facilities, conference rooms, and warehouses as targets for the LEDs. The applications on that list share the need for uniform light, high energy efficiency, and relatively low procurement costs.

The Duris E 3 LEDs have a broad 120° beam angle and measure only 3×1.4 mm. Osram intends for the LEDs to be mounted closely together so that a person perceives “a single bright strip of light.”

“This new LED extends our portfolio in the low-power range and offers the usual high OSRAM quality,” said Andreas Vogler, Product Manager SSL at Osram Opto Semiconductors. “Bright LEDs are also recommended for smaller offices, shop lighting and signage.”

Osram will offer the new LEDs in a broad range of color temperature ranging from 3000K to 6500K. At 5000K the LEDs feature a CRI of 72 and deliver efficacy of 110 lm/W.

The company plans to follow the Duris E 3 with a larger and brighter LED later in the summer. The Duris E 5 will measure 5.6×3 mm.

Linear SSL trends

The trend toward purpose-built SSL-based linear fixtures is a strong one. Back in April, Cree announced the CR family of linear SSL fixtures was meant to replace tube-based fixtures.

At the recent Lightfair International (LFI) show, Cooper Lighting announced an LED module that was designed specifically for linear SSL fixtures. Moreover, the company has integrated the module into 32 different luminaires that carry different Cooper brands.

Osram Sylvania (a sibling business to Osram Opto) also launched a modular product at LFI that is meant for usage in 2- and 4-ft linear fixtures. The LED Distributed Array system combines 48 low-power LEDs on a 2×9-in circuit board. Luminaire designs can combine multiple modules to yield most any size fixture.

It’s not clear if the Sylvania module utilizes the Duris E 3 LEDs that were announced after LFI. But the LED Distributed Array press release issued at LFI makes familiar sounding claims saying the module offers uniform light with no hot or dark spots.
