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.
Research Association Produces Prototype LED with 256 Light Points for Adaptive Front Lighting Systems LIGHTimes News Staff
October 23, 2014...Osram Opto Semiconductors reports that after just one and a half years, the
company and its partners on the µAFS research project have developed a new LED
chip with an unrivaled array of 256 light points (pixels). Previously pixel
systems were based on a large number of individual LEDs. Funding for the
project, a total of seven million euros, comes from the Federal Ministry of
Education and Research as part of its focus on “Integrated
Microphotonics”. The project will run until January 31, 2016.
The project's goal is the development of a new class of energy-efficient LED
headlamps which may then provide the basis for adaptive front lighting systems.
The project intends to design systems that will improve the illumination of the
road ahead through actively adapting the light distribution for the driving and
traffic situation without dazzling other road users.
Experts from Osram Opto Semiconductors, Osram Specialty Lighting, Infineon
Technologies and the Fraunhofer Institute for Reliability and Microintegration
IZM jointly developed a prototype of an LED-based adaptive front lighting
Previous adaptive front lighting systems (AFS) have one pixel corresponding
to one LED component or one chip. However, in this prototype one chip contains
256 pixels, which can all be individually controlled. Osram Opto notes that the
256 pixels per chip prototype is the first step to light sources with more than
1000 pixels. Osram Opto Semiconductors developed the new pixel chip with
defined light patterns in blue and white . According to Osram Opto, the
challenge was to define the light points during chip processing itself and
enable them to be linked directly with the control system. Infineon
Technologies developed the driver chip to directly and individually control the
numerous light points. As the specialist in mounting technology, Fraunhofer IZM
made it possible to couple the light-emitting pixel chip with the controlling
Osram Opto Semiconductors structured the chip surface and attached the
converter for creating white light to complete the prototype. This demonstrator
proves the feasibility of having a particularly high resolution, which is
needed to enable the dynamically adjustable light pattern with a high degree of
precision. Osram Opto Semiconductor contends that the technology in the
prototype will open up special automotive lighting options such as city lights
and bad weather lights.
In one of the next steps, the Osram Specialty Lighting business unit,
intends to transfer the prototype to a light module with electrical, mechanical
and thermal interfaces. Future goals of the project include developing
intelligent control and an appropriate connection to the vehicle bus to ensure
extremely fine control of the light.
µAFS project partners Hella, the automotive lighting specialist, and
Daimler, the car manufacturer, will then take over. Hella is responsible for
the development of the optical system and the thermal management system,
including the design of the complete headlight. Daimler has already contributed
specifications and requirements for the bus connection and optics within the
project, and is responsible for detailed testing of the headlamp and therefore
for the final process.
Jacket Mimics Chameleon LIGHTimes News Staff
October 21, 2014...Remember those TVs with ambient LEDs that were introduced a few years ago
but never really caught on, a company called Drap og Design has created a
jacket with an analogous, chameleon-like function. Drap og Design's Interacket,
which is presented on maker site Hackaday, allows your jacket to mimic the
colors of objects that you touch. Built in sensors detect the color of objects
you touch with your hands. Strips of RGB LEDs change color to match the color
of the object that your hand touches. The kit uses Adafruit Neopixle LED
strips, Adafruit color sensors, and a pair of Arduino Uno Chips. The system is
powered by a single 9V battery
The kit uses a pair of Arduino Uno chips, Adafruit Neopixel LED strips and
Adafruit color sensors, all powered by a single 9V battery. The jacket itself
is made of reflective foil and diffusive fabric to allow the coat to
prominently display the colors picked up by the sensors. From the video, you
can see that the design groups first prototype is cool but it does not have
practical uses. It is far from the resolution required for practical uses in
defense or military applications.
The company says that it has nearly completed its second prototype of the
Interaket. Who knows what future iterations of the jacket could be capable of.
Drap og Design says it also has other design ideas that it is developing that
attempt to give humans the "powers" that some other animals have. You can check
