XL Video Provides LED Columns for Hugo Boss Event
LIGHTimes News Staff

December 16, 2014...Working for client, Bureau Betak, XL Video supplied 40 4-sided LED columns and media control for the New York Fashion Week show of Jason Wu for Hugo Boss. The show took place at 4 World Trade Center on the eve of 9/11. Agency Bureau Betak approached XL Video’s senior account executive, Tim Riley, to design and produce the catwalk event. Bureau Betak asked Riley to deliver dozens of 10’ tall columns of LED displays.

Each of the 40, one-foot-wide square columns was encased in XL’s Pixled 9mm LED video display. To make the columns appear seamless, XL Video’s R&D team in China manufactured a set of custom rails for the LED to clip to. The custom rails were affixed to the wooden columns that the set company built. The rails ensured that all the LED could be mounted to the columns in just 24 hours by XL’s Project Manager, Will Nazarowski and lead LED technician, Curtis Luxton.

Don Stevens, liaised with both Bureau Betak and the content creators to map-out the content across all 160 facets of LED to ensure the client’s content looked flawless and flowed across the columns.

Stevens controlled the content on the day of the event using one of XL’s Stumpfl Wings Quad media servers.

Tim Riley commented, “Bureau Betak came up with and delivered an incredible design for Hugo Boss. The show inside the new 4 World Trade Center building, just a day before 9/11, made this a topical and poignant event, and was made more impressive by its view and location on the 48th floor.”

LEDs Help Algae Grow in the Tank
LIGHTimes News Staff

December 11, 2014...Scientists at the Technische Universität München (TUM) have developed together with the Berlin LED manufacturers FUTURELED a methodology of simulating a wide variety of lighting conditions. The scientists are studying the growth of algae with various light conditions.

According to estimates, there are about 50,000 algal and cyanobacterial species. However, only about 5,000 of these are known to date. Of these, only ten species have been grown for a commercial use. Algae and cyanobacteria can thrive even in salt water pools or on infertile soils and use much less energy to grow than food crops. Researchers are also looking to Algae to potentially be used in the production of aviation fuel.

"Algae grow much faster than soy or corn. You do not need fertile soil, pesticides per hectare per year and could bring a ten times higher yields, " said Professor Dr. Thomas Brück , head of the Department of Industrial Biocatalysis the TU Munich.

Scientists have already discovered numerous interesting products from various algae species. Many algae can produce, protein mass or build fat's chemical intermediates. Protein mass could be used as fodder to fuel or could be produced from the fats.

However, they have found that even within a species the ability to produce certain products is highly variable. "In our studies, we see again and again large differences in productivity," says Thom's camp. "We have to find not only the right kinds but also uses the candidate with the highest productivity breed."

The researchers worked with Berlin company, FutureLED to develop a light and climate simulation to optimize algae cultivation. The researchers use combinations of colored LEDs to simulate the spectrum of sunlight.

"No one can predict whether an alga from the South Seas under the lighting conditions in Germany is as productive as in their home," said Thomas Brück. "Nor do I know what this successful candidates would still be just as successful under the lighting conditions of the Sahara.All this we can test in our laboratory now. "

The efficient LEDs offer light that is between 400 and 800 nanometers in wavelength with a radiant power of up to 1000 watts per square meter and the sunlight comes close to uniform intensity distribution. Scientists can control the different types of LEDs individually to set individual spectra. Fluorescent and incandescent bulbs produce too much heat and do not allow the easy light variation. The researchers specifically needed the LEDs to activate the molecular switches of the algae that help control plant growth.

The project is funded through Industrial Biocatalysis project in the framework of the research project algae aviation fuel. Other project partners are the Departments of Biotechnology (technical scale cultivation) TUM and Chemistry II (catalytic conversion, Clariant AG (algae processing, fat separation) and the conys GmbH (hydrogen / biogas production). South of Munich, on the campus Ludwig Bölkow (LBC), researchers are currently building on the campus Ludwig Bölkow (LBC), a technical center for the study of the algal culture on a large scale. The Free State of Bavaria and the Airbus Group supporting the project with 12 million euros.

New Infrared LED from Osram for Biometric Identification Systems
LIGHTimes News Staff

December 11, 2014...Osram has debuted the Oslux SFH 4780S, a high output IR LED that emits at a wavelength of 810 nm. Osram notes that the IR LED with a height of just 2.4 mm and a narrow emission angle, could pave the way for reliable, energy efficient biometric identification such as iris scanning incorporated into mobile devices. Osram contends that a wavelength of 810 nm is particularly suitable because it can provide high-contrast pictures of the irises of any color at comparatively low levels of light.

"The SFH 4780S from Osram Opto Semiconductors currently offers the best performance-to-size ratio. The SFH 4780S is the first IRED in the new high-performance Oslux package. Oslux LEDs have long been established for visible lighting applications in mobile devices, such as camera flash. We are now extending the range to include infrared emitters," explained Bianka Schnabel, marketing manager for infrared products at Osram.

Oslux components offer a narrow emission angle at a low height because they perfectly match the lens to the internal reflector. Also, despite the use of a lens, the Oslux has a flat component surface. Despite the low height of 2.4 mm, developers have managed to achieve an emission angle of only +- 10 degrees for a record radiant intensity of typically 2900 milliwatts per steradiant (mW/sr) at an operating current of 1 amp (A).

The IR LED's high optical output comes from a stack of two thin-film chip with an edge length of 750 mm arranged one above the other with the aid of Osram’s nanostack technology. The emitter can operate with a current of up to 2 A in pulsed mode. Thanks to its black package, the SFH 4780S can be integrated unobtrusively behind the covers of mobile devices.

Unlike current designs which often use several IREDs, this new IRED with high radiant intensity enables the iris scanner operation with just one compact emitter. Like all applications that expose the eye to infrared light, iris scanners must comply with the relevant eye safety standards.

Osram Moves Toward Fewer LEDs Per Traffic Light
LIGHTimes News Staff

December 9, 2014...Osram has introduced the surface mountable Oslon Signal 120 for traffic lights. Shanghai Austar Lighting Electrical Industry Co., Ltd., has passed the Chinese national traffic light certification standard GB14887 with its LED traffic lights. The solution uses high brightness LEDs that are specifically designed for operating at high currents and high temperatures. Traffic lights with LEDs are known for their long operating performance. Osram's Signal LEDs support cutting edge traffic light designs with a significant reduced number of LEDs per signal.

“High-power LED traffic light is considered the next development direction of urban traffic signal facilities. Osram Opto Semiconductors has long been a forerunner that promoted technical innovations and their extensive applications. The passing of the Chinese national certification of Austar’s High Power Traffic Lamps proves again all the advantages that LED technology can offer to our customers’ lighting solutions,” explained Marcus Wong, Senior Marketing Manager of Osram Opto Semiconductors.

Oslon Signal 120 comes in a tiny ceramic-based package. It can reportedly operate with high efficiency even at high temperatures. Osram Opto Semiconductor's yellow LED employs the company's high efficiency ceramic converter (C² technology), which makes the yellow Oslon Signal ideal for use even at high currents and high temperatures.

Instead of a typical light output of 26 lumen (lm) at Tj = 85° (junction temperature), the company managed to increase the light output by about 300 percent to 80 lm at the same temperature. The LED's typical brightness is 100 lm at an operating current of 350 mA. These LEDs for traffic signals use the company's UX:3 Chip technology and lens, and with the 120 ° beam angle The company notes that the compact component size (3 mm x 3 mm x 1.7mm) is very easy to cluster and is perfect for standard secondary lenses for signal lights. Oslon signal is designed for international use, and the company says it meets the relevant standards for traffic lights: ITE 2005 in the USA and EU EN 12368 in Europe. The signal LED has an estimated life of 100,000 hours, more than five times that of conventional LED traffic light sources.

Shanghai Austar is one of the leaders in the domestic traffic signal sector. Osram Opto Semiconductors worked with Shanghai Austar on high-power LED traffic lights since the year of 2011. Mr. Yu Weiming, General Engineer of Austar pointed out, “Osram Opto Semiconductors with its technical advantages and R&D strength in LED lighting technologies makes a great partner for us. I believe that our cooperation can further the application and population of the high-power LED in the traffic signal sector. Traffic lights look simple, and yet as new optical technologies develop, the current application mode of traffic lights will be changed, and that will bring about a new industry opportunity."
