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

Osram Supplies LED-based Front Lighting for 2015 Ford F-150 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
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
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
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
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.
Curved TV Screens Jump Into Global Market LIGHTimes News Staff
April 8, 2014...NPD Display search forecasts that shipments of curved TVs will reach almost
800k units in 2014 and are predicted to be more than 6 million units by the end
of 2017. According to the company, curved TV is a feature that is expected to
reach its peak in LCD TVs in 2016. Then, growing shipments of OLED TVs are
predicted to increase curved TV shipments in 2017.
After two straight years of declining revenue from the global TV market,
brands are exploring numerous avenues to revitalize the business such as curved
screens, OLED displays, and increased resolution (4K or Ultra-HD).
“The novelty of curved screens is expected to wear off with time,
leading to shipments peaking and then trailing off,” said Paul Gray,
director of European TV research for NPD DisplaySearch. “Even so,
curved screens will have completed the important task of differentiating new
high-end models, thereby helping to boost overall value in the global
Curved LCD displays first emerged at IFA 2013. Samsung, LGE, and several
Chinese brands showed curved screen LCD TV models at the 2014 Consumer
Electronics Show (CES), but the companies are hedging their bets with other
features. “Brands are not staking their futures only in curved screens or
any other single feature, but are instead exploring a whole mix of features to
attract TV buyers,” Gray noted.
OLED TVs are getting much attention, but they still face significant
manufacturing difficulties. NPD Display Search says that at best only 100K will
ship in 2014, and annual shipments are expected to reach only over in 2016.
“LCD has proved a tough act to beat, because it is a mature,
efficiently-manufactured technology, with a surprising amount of room for
innovation,” according to Gray.
Companies are racing to get the best screen resolution. This year, Netflix
announced 4K streaming services to support expansion of the category. The
number of ultra-high-definition (UHD) 4K TVs shipped in 2014 are forecast to
exceed 12M units and increase to 62 million in 2017. China will reportedly
dominate demand and shipments of 4K TVs with an 83% share of 4K TV shipments in
2013, falling to 46% in 2017, as other countries catch up. “4K TV is
currently grabbing a lot of headlines, but it would not have been possible to
deliver 4K, had there not been investment in connected TVs, over the past five
years,” Gray said.
April 3, 2014...German automotive lighting company Hella, has used bent OLED modules in a prototype for combination rear lamps. A total of 28 of these differently shaped OLED modules produce three-dimensional, illuminated structures. LG Chem and BMW collaborated with Hella to develop the prototype design , which was unveiled at Light + Building 2014. This design sample will be showcased at the stand of the OLED specialist, LG Chem.
OLEDs, which are made up of are very thin, organic, semi-conductor layers, generate light over a complete area. The OLED's bent shape is made from a flexible OLED substrate. Hella notes that the flexible OLED can be made into virtually three-dimensional shapes with bend radii of just a few millimeters. Hella reports that it is in the process of developing technologies for a rigid, bent OLED module.
