Mercedes-Benz CLS Class Uses Oslon Compact LEDs for Adaptive Front Lighting LIGHTimes News Staff
October 31, 2014...Mercedes-Benz has equipped its new CLS Class automobiles with adaptive front
lighting systems with Oslon Compact LEDs from Osram Opto Semiconductors. The
company says that the very compact, high-power LEDs, which measure 1.6mm by 1.2
mm, can be placed very close together in the headlight systems for adaptive
front lighting. In addition to this current project, Osram and Daimler are
collaborating to devise future automotive lighting systems as partners in the
µAFS research project that the German Federal Ministry of Education and
Research (BMBF) sponsors.
The adaptive front lighting system for the new CLS reportedly helps increase
visibility in every situation. Each module within the headlight consists of 24
LEDs that use the company's UX:3 chip technology to achieve high luminous
efficacy even at high currents. The modules can be arranged close together in
the headlight with a high degree of flexibility. Osram Opto notes that these
LEDs therefore provide the basis for both AFS and light guide solutions.
A camera mounted on the windshield covers the area in front of the vehicle.
From this camera four controllers select which LEDs to brighten, which to dim,
and which to turn off completely to achieve the ideal light distribution. The
controllers perform calculations based on the input from the camera 100 times
per second to determine the best lighting for the driver.
Osram Opto Semiconductors Launches Displix Oval for Outdoor LED Displays LIGHTimes News Staff
October 30, 2014...Osram Opto Semiconductors has introduced a surface-mountable, oval-shaped
LED for outdoor displays called Displix Oval. It measures just 2.1 x 2.7 x 1.5
mm. The company contends that this small footprint allows almost twice as many
LEDs to be mounted on a board than with ordinary radial diodes, doubling both
the pixel density and the display resolution. According to Osram Opto the
higher pixel density and resolution results in extremely vivid images with high
The company points out that the high pixel density allows lower brightness
for individual pixels. Therefore, individual LEDs can operate on lower current.
Furthermore, the company says that combined with the durable packaging
materials, the lower required output extends the lifetime of the LEDs.
The Displix Oval has a black QFN (Quad Flat No Leads) housing, which the
company claims reduces reflections and increases the contrast and color quality
of the images displayed on the entire display.
“Being surface mounted, SMT LEDs like the Displix Oval have very
low tilt tolerances per diode. A display fitted with the new LEDs hence has a
stable and very homogenous color appearance when viewed from virtually any
angle,” said Sven Weber, who is in charge of product marketing of
the Displix Oval at Osram Opto Semiconductors.
According to the company, both the processes and the processing of the
Displix Oval are much simpler than with radial LEDs, greatly reducing OEM
customers’ further processing costs.
Additionally, the very flat Displix Oval requires less silicone for the
potting of the boards to protect the contacts from rain and moisture. This
enables customers to reduce the amount of material used, which again has a
considerable impact on their outlays. The LED has beam angles of 110°
(horizontal) and 60° (vertical). Red and yellow offer 1 candela, the green
version delivers 2.6 candela, and the blue provides 600 milli-candela.
LG Announces End of Plasma TV Business LIGHTimes News Staff
October 30, 2014...LG Electronics of South Korea has officially announced the wind down and end
of its Plasma TV business, which will be by November. According to a Reuter's
LG Electronics revealed in regulatory filing that demand has declined in for
plasma TVs. LG said that the Plasma TV business currently accounts for only
about 2.4 percent of its revenue. LCD TVs have taken over the global market,
and OLED TVs are beginning to gain a foothold in the high-end TV market.
Reuters cited analysts who said that plasma displays were unable to compete
with the advances in screen resolutions and the lower power consumption of
LCD-TVs. LED backlit and edge lit TVs are starting to gain market share as
Market research firm, NPD DisplaySearch predicted in July that global plasma
TV shipments will decline to 500,000 in 2015, which is more than a 90 percent
drop off from the 5.2 million in 2014.
Samsung remains the only major display maker to still produce plasma TVs.
Panasonic reportedly exited the Plasma TV business last October.
Study Finds LED Lighting Can Increase Production in Hot, Un-Air Conditioned Factories LIGHTImes News Staff
October 30, 2014...One often overlooked but important benefit of LED lighting is that it
produces less heat than competing lighting technologies. For this reason, LED
lighting can boost productivity in factories in already hot climates without
air conditioning, according to researchers led by Achyuta Adhvaryu, an
assistant professor at the University of Michigan Ross School of Business.
Un-airconditioned multi-story buildings are apparently also common in
Bangladesh, China, Indonesia, Vietnam and other major exporters in the $200
billion apparel industry.
The researchers examined the lighting related electricity costs,
temperature, and productivity at 25 garment factories in Bangalore, India from
2010 to 2013.
"Heat stress stops the body's capacity to exert, so workers are less
able to complete production targets," said Adhvaryu.
They reported that Hundreds of Workers labor at machines that run constantly
in multi-story buildings without air conditioning. The researchers assert that
finding ways to keep factories cooler will become increasingly challenging for
businesses in developing countries, which on average are hotter than developed
The researchers studied the staggered rollout of the LED lights in the
factories over four years. They found the LEDs cost about $6,300 to install,
and the energy savings was about $3,000 per year.
They found an average increase of about $41 per operating day for each
factory. This translates to nearly $13,000 per factory per year.
"LEDs create a productivity gain that dwarfs the energy savings,"
Namrata Kala of Yale University and Anant Nyshadam of the University of
Southern California were co-authors of the study.
Samsung Ends LED Lighting Business, Continues LED Components Business SSL Design News Staff
October 28, 2014...Samsung Electronics Co. Ltd. reported that it will end its LED lighting
business outside of South Korea. The company began the LED lighting business
just four years ago, but has seen increasing price pressure from rivals in
recent years. Pricing pressure across the industry has also lead Philips of the
Netherlands, a Samsung rival, to recently spin off its 100-year-old lighting
business, and it has lead Osram another LED lighting business rival to lay-off
about 8,000 employees.
A Reuters report cited an emailed statement from the company, "We will
remain active in the LED industry through our LED component business,"
adding that Samsung will focus on backlighting for displays of consumer
products like televisions.

cycling, and urban informatics. MeU says cyclists can display a flashing
pattern or other signals on their backs to communicate with other road users. A
group hike leader can keep participants informed or a construction worker can
wear a blinking patternto help alert those passing by of potentially unsafe
The company says that the ability to display public transit updates on the
vests of employees or receive weather alerts from pedestrians can help the city
to run smoother. Having been featured in Toronto's first men's fashion week,
the product can also portray a dynamic fashion statement.
The full-color LED matrix display consists of 256 LEDs, a microcontroller,
and a Bluetooth radio that enables wireless communication with other devices.
The company contends that the thin and flexible panel conforms to the body and
can be worn with any style of clothing. After downloading the smartphone app,
the user can choose from existing icons and animations or create their own
content to send to the LED display.
"We're looking for tech savvy developers, who are open to working with
the initial developer kit," added Tu. "The kit includes the MeU
Square, a rechargeable battery, a micro USB cable, and the MeU Demo Mobile

GaN LEDs in Automotive to Reach $1 Billion in 2014, According to IHS LIGHTimes News Staff
October 23, 2014...The LED Intelligence Service of IHS Technology (IHS) predicts that the
market for GaN packaged LEDs in automotive applications will reach the $1
billion mark this year for the first time. IHS forecasts that industry revenue
will grow 11 percent from $943 million in 2013 to $1.05 billion in 2014. IHS
contends that the growth comes from vehicle exterior applications such as
headlamps and daytime running lights, where LED penetration is still low.
However, IHS notes that the LED value per vehicle can be quite high. Osram,
Nichia and Lumileds are ranked by IHS as the market's leading three suppliers,
and IHS says they are particularly dominant in vehicle exterior
Audi has been a leader in using LEDs in its vehicles (especially in daytime
running lights) since 2008, according to IHS, and many other manufacturers have
followed the trend to using more LEDs in automotive applications. IHS points
out however that many vehicles even at the high end of the market such as the
$100,000 Tesla Model S, still do not use LED headlamps. Moreover, daytime
running lights, cornering lights and indoor ambient lights are only available
as an option rather than as standard. IHS forecasts that LED lighting should
increase in vehicles over the next several years, growing further to $1.3
billion in 2018.
