GE Introduces LineFit Light LEDs to Retrofit Fluorescent Cabinet Signs
LIGHTimes News Staff

April 24, 2014...GE has debuted the LineFit Light LEDs to replace or upgrade fluorescent cabinet or box sign lighting systems with LEDs. The new GE LineFit Light LED system delivers 58 to 76 percent energy savings compared with T12HO fluorescents. The systems are available in 11 sizes and three color temperatures for a variety of double-sided signage sizes and styles.

“LED lighting offers several benefits and improvements for outdoor signage lighting compared with standard fluorescents. From significant energy cost reductions and easier job site installation, to less frequent maintenance and more consistent brightness, as well as uniformity and cold weather performance across your signs, LED stands as the ultimate choice,” said Mark Shepard, global product manager for GE Lighting. “GE’s new LineFit LED system offers all these benefits and more with the potential to save money not just in operation, but on the installation as well.”

The GE LineFit Light LED modules utilize existing fluorescent sockets (R17d) for an easy four-step installation that GE says takes just minutes per fixture. LineFit Light has rotating end caps to align the light output with the sign face. The systems employ GE’s patented OptiLens™ optical lens technology to efficiently use light, while protecting each LED against damage, corrosion, moisture, and humidity. While conventional fluorescents emit light in a 360-degree pattern, each LED module is designed to capture otherwise wasted light and redirect the light toward the lit surface of the sign. GE's OptiLens technology also eliminates shadows and striping on the sign face that fluorescent tubes can cause. The system has a rated life of 50,000 hours.

Schott and Lufthansa Technik Create Homogeneous Lighting for Airplane Cabins
LIGHTimes News Staff

April 24, 2014...Schott and Lufthansa Technik are planning to introduce a new cabin lighting solution for aircraft cabins. The new lighting solution called HelioJet SpectrumCC (Color Control) is designed to make sure that the color is rendered consistently with sensor technology that displays colors homogeneously. Schott will debut the HelioJet SpectrumCC at the Aircraft Interiors Expo in Hamburg, Germany.

Schott points out that most LED systems cannot maintain homogeneous color because they employ a single chain of LEDs. Each LED die ages at a different rate and colors are rendered differently, depending on the color's shade and the temperature of the LED. This results in inhomogeneous colors that cannot be uniformly controlled even with conventional light management systems.

The new True Color Sensor ensures that each LED in the system renders colors in the correct color shade. The company claims that the sensor is about as sensitive as the human eye to render the results as realistically as possible. The sensor system compares the light emitted from each diode to a target value. The sensor system also allows Lufthansa Technik's "nice" cabin management system to control the colors emitted by the lighting solution. HelioJet SpectrumCC employs an optical light converter using four LEDs (Red, blue, green, and white) to create the precise color of light required.

The HelioJet system is in three subsections. Colored LEDs are at the end of each subsection for a total of six LED clusters per product. Each of the red, blue, green and white LEDs in the RGBW clusters emits a point of light. The points of light in the primary colors and white mix into color shades within the light converter. The system reportedly can create any desired color and color shade and maintain it across all of the HelioJet SpectrumCC units at a defined level of brightness.

According to the company, HelioJet consumes significantly less energy than traditional fluorescent tubes and lasts much longer. Schott says its mean time between failures is at least 50,000 hours. Furthermore, Schott says that maintenance and repair costs are lower because the LED clusters within the system can be easily replaced.

“We have received extremely positive feedback from potential customers. This confirms that we are on the right track. We expect the qualification phase for HelioJet SpectrumCC to be completed in the second half of 2014,” explained Dr. Armin Plichta, general manager transportation at Schott Lighting and Imaging. Schott and Lufthansa Technik work together to develop cabin lighting concepts for commercial airliners, business jets, and VIP airplanes.

LIGHTimes News Staff

April 22, 2014...More and more vehicles are using LED lighting as standard design features worldwide. Several cars from the Chrysler Group are getting LED Lighting. The 2015 Chrysler 200 Sedan has the signature Chrysler grille and winged badge, LED light pipe accents in the front projector headlamps, LED tail lamps. The LX and Touring models of the 2015 Chrysler 200 Sedan also come with ambient LED lighting.

Other Chysler Group brands, Jeep and Dodge, have introduced LED lighting for their upcoming models. Jeep designers introduced the 2015 Jeep Wrangler's Sundance Design Concept which includes unique front and rear bumpers equipped with linear LED lighting. Dodge also decided to design its 2015 Charger with LED lighting in the front and rear. The Charger features new Dodge signature LED racetrack tail lamps and LED fog lamps.

Another American car maker, Ford (not a Chrysler Group company) also recently debuted the new design of the F-150 pickup with LED-based headlamps. This LED lighting treatment in cars is part of a trend of equipping standard and mid-range models with LED lighting in addition to its already significant presence in Luxury automobiles.

HELLA'S LED Matrix Lighting Wins Award
LIGHTimes News Staff

April 17, 2014...HELLA KGaA Hueck & Co., of Plymouth, Michigan, a supplier of automotive lighting, has won the 2014 Automotive News PACE award for its adaptive LED Matrix Beam technology. Individually controlled LEDs in HELLA's “glare-free high-beam” headlights adjust automatically to real-time traffic conditions to reduce glare for other drivers. While these adaptive headlights are available in Europe, United States regulations prevent their incorporation into automobiles.

In the Matrix Beam system, a front camera and high-performance software continuously monitor both following cars and oncoming traffic and adjust the light output accordingly. The system automatically adjusts a car's headlamps to provide ”glare free” illumination, switching on and off, or dimming based on traffic conditions. Individually controlled LEDs also create up to 8 dark zones with “light in-between,” allowing continuous use of a vehicle's high-beams to maximize visibility.

Uniquely, HELLA's system utilizes 25 individually controlled LEDs arranged in a matrix to create an almost unlimited variety of lighting patterns. The solution does not depend on mechanical parts and is more durable than conventional lighting systems.

Daktronics Improves Cubs Park Experience
LIGHTImes News Staff

April 17, 2014...New LED video displays were visible at Cubs Park in Mesa, Arizona where the Chicago cubs play spring training games. Daktronics of Brookings, South Dakota, designed, manufactured, and installed the new LED displays. The main LED display features a 15HD pixel layout and measures about 17 feet high by 53 feet wide. The main display can show one large image or be divided into separate windows for graphics, animations, statistics, scoring information, and sponsor advertisements. The clear, high contrast main display allows wide angle visibility and has multiple levels of protection from the elements.

The installation also includes a ribbon display measuring about 3.5 feet high by 60 feet wide with 20 millimeter line spacing. The ribbon display can showcase sponsors or show statistics and game information. A Daktronics fixed-digit scoreboard provides stats such as at-bat, ball, strike, out, hit/error, runs and inning scores. A small-scale, two-sided monochrome marquee display was installed to mimic the iconic red marquee outside of the Cubs home, Wrigley Field. Fans can stand next to it and take pictures as well as program their own text onto the displays.

"We're excited to provide these displays to Cubs Park," said Brady Jacobsen, Daktronics sales representative. "We understand that spring training has become a larger part of baseball's year-round fan experience and we're confident this installation will cater to fan expectations at such events."

The Cubs also received a bank of hours for the creation of digital content to be produced and delivered by Daktronics Creative Services at the request of the team.

LIGHTimes News Staff

April 17, 2014...The 2015 Ford F-150 will be the first pickup on the market with full LED-based forward lighting. Osram will supply LED modules for the headlamps on the Ford F-150. In cooperation with US headlight maker Flex-N-Gate, Osram has given the front of the 2015 F-150 a new look. Osram Opto Semiconductors, Osram's subsidiary supplies the LED modules for the pickup's front lights. Osram assembles the completely LED-based lighting solution at its Hillsboro plant in New Hampshire.

The highly robust and durable LED lighting is extremely resistant to shocks and vibrations. Additionally, the LED headlamps consume far less energy than conventional automotive lighting technologies, and their light color is reportedly very similar to that of natural daylight.

"We are proud to be supplying the LED module for the world's first LED headlamps on the Ford F-150 as standard, once more underlining our leading position on the automotive lighting market," said Hans-Joachim Schwabe, CEO of the Specialty Lighting Division at Osram. The lighting system includes high beam, dipped beam, turn indicators, parking light, and a control module.

Up to 1.1 Gigabit per Second LiFi Transmission Using Micro LEDs is Possible Over 10 Meter Distance, According to Researchers
LIGHTimes News Staff

April 10, 2014...Harald Haas, a University of Edinburgh professor, chief science officer (CSO), and co-founder of pureLiFi, and his team demonstrated that up to 1.1 gigabit per second (Gbps) can now be transmitted using light from micro LEDs over a distance of 10 meters with less than 0.5W power. LiFi is a term reportedly coined by professor Haas in which light is used to transmit data wirelessly in a way that enables full networking capabilities similar to WiFi. However, LiFi has greater spatial reuse of bandwidth

The process uses just 5% of the power of a typical 10W LED light bulb. Therefore, lights can be dimmed while maintaining high LiFi data rates and coverage. Furthermore, the researchers found that the distance at which 1 Gbps is possible with a single color LED is 10 times larger than previously reported.

EPSRC funded the work as part of the Ultra Parallel-Visible Light Communications (UP-VLC) program grant. Haas collaborated with partners from the Institute of Photonics at the University of Strathclyde, the University of Glasgow, and the University of Oxford.

pureLiFi successfully demonstrated of the first commercial Li-Fi product, Li-1st, at MWC 2014 and CeBIT 2014 in March and added a second production run of the Li-1st to meet the demand from industry customers. The new production run is scheduled to ship this month. Haas founded pureLiFi (formerly pureVLC) as a spin-out from the University of Edinburg. The company produces LiFi drivers and receivers.

Professor Haas said, “Li-Fi is revolutionizing wireless communications and showing that Li-Fi can be the enabler of the emerging Internet of Everything. By transmitting data at speeds above 1 Gbps and record distances of 10 metres at a fraction of the power of typical LED bulbs, we continue to make the technological leaps and bounds that make Li-Fi a technology that could transform the way we use the internet in the near future.”

Tetris is Played on Cira Centre in Philadephia
LIGHTimes News Staff

April 8, 2014...Two sides of the 29-story Cira Centre in downtown Philadelphia were transformed into a giant game of Tetris as part of the kickoff to Philly Tech Week on Saturday. Sam Robinson was one of the lucky participants who got to play the famous game on the 100,000 square foot screen formed with LED lights. Tetris has been played on buildings before, but the size of the game on the north and south faces of the Cira Centre building may be a record.

“It has been probably 15 years since I played Tetris last on a Game Boy, and it’s much different playing on the side of building that’s a half-mile away,” Robinson said.

Organizers hoped that the grand exhibitiion would inspire players and onlookers to imagine technology's possibilities. The hundreds of LEDs mounted on the building's glass walls normally display patterns, but on Saturday night enormous shapes fell and piled up as players attempted to maneuver the falling puzzle pieces so that an entire row could be filled and then erased before the pieces piled up to the top.

Frank Lee, associate professor of digital media at Drexel University, oversaw the creation of the giant game on Cira Centre to celebrate the upcoming 30th anniversary of Tetris. Tetris was created by Russian computer programmer Alexey Pajitnov in 1984 and was eventually put on numerous gaming platforms. The game's popularity took off after it was put on the original Nintendo Gameboy.

Lee addressed a crowd of onlookers saying, “This project began as a personal love letter to the games that I loved when I was a child – Pong last year, Tetris this year, but it ended up as a way of uniting the city of Philadelphia." Lee previously set the Guinness World Record for the largest architectural video game display for playing Pong on one side of the Cira Centre last year.
