Osram leads LED project to serve many markets
ADAPTIVE FORWARD LIGHTING, or glare-free camera-controlled headlamps that react instantly, will be helping drivers even more in the future thanks to additional intelligent functions.
The key to this complex functionality is the integration of microelectronics and optoelectronics. This is one of the principal aspects of the research project sponsored by the German Federal Ministry of Education and Research (FMER) within the “Photonics Research Germany” program.
Osram is contributing its expertise as the project coordinator in LED lighting for the automotive sector. The aim of this joint project as part of the FMER “Integrated microphotonics” initiative is to develop the technical framework for a new class of energy-efficient LED headlamps with supplementary traffic safety functions. This could provide the basis for adaptive forward lighting systems (AFS) that offer drivers and passengers increased safety. Improved safety will come for example
system. The Fraunhofer Institute for Reliability and Microintegration (IZM) is contributing its expertise in interconnection technology and materials, and Infineon Technologies is offering its experience in automotive electronics and LED drivers.
The automotive industry supplier and lighting specialist HELLA KGaA Hueck & Co. will develop the entire optical system for the LED module and the headlamps, and will build prototypes. Daimler, a major engineering power-house in the automotive sector, will carry out the vehicle tests.
from glare-free high-beam and low-beam that adapts to the speed of the vehicle.
At high speed the range of the light is automatically increased. In city traffic however a wider distribution of the light can improve road safety by illuminating more of the sidewalk and margins. These functions are fully electronic so there is no need for mechanical actuators. Osram has extensive know-how in chip and converter technologies. The company’s Specialty Lighting division will be developing new electronic control gear for controlling the LED headlamp
Project coordinator Stefan Grötsch, responsible for LED applications in automotive lighting at Osram Opto Semiconductors, is satisfied with progress so far. He says, “We have brought together major-league players in their respective sectors, assembling a wealth of expertise for this pioneering project around one table.”
The project is being sponsored by the German Federal Ministry of Education and Research (FMER) under reference number 13N12510 and is scheduled to run from February 1st, 2013 to January 31st, 2016.
Xilink and Sumitomo Electrics collaborate to smarten networks and reduce costs to market
XILINX AND SUMITOMO ELECTRIC are collaborating to bring smarter solutions to market. The firms say these solutions reduce CapEx and OpEx costs through the use of Sumitomo Electric’s GaN power amplifier transistors and Xilinx SmartCORE IP that result in higher radio unit efficiencies.
Wireless system designers using Xilinx’s SmartCORE IP can scale to support small cells to high-end macro cells, as well as active antenna systems (AAS).
This offers customers time-to-market advantages, lower development costs, high efficiency, lower SWaP (size, weight and power), and lower total cost.
Xilinx radio SmartCORE IP such as Digital Up and Down Converters (DUC/DDC), Crest Factor Reduction (CFR) and Digital
Pre-Distortion (DPD) IP cores, coupled with generation-ahead 28nm
Zynq-7000.All Programmable SoCs, offers customers a single-chip implementation of the entire digital radio in addition to board level control and calibration typically found in an external processor.
“By collaborating with Sumitomo Electric, we are able to provide our customers with a smarter solution that is scalable to support the needs of broadband microcells, and up to the highest performance multi-antenna broadband macros and AAS installations,” says David Hawke, director of wireless product marketing at Xilinx.
“Additionally, our radio IP, coupled with Sumitomo Electric’s power amplifier transistors, allow OEMs to design equipment that ultimately save operator CapEx and OpEx, as well as reduce
device cost and power.” The high breakdown voltage and saturation velocity characteristics of GaN devices make it an ideal candidate for high-power and high-temperature base station applications.
The higher power density of GaN also allows for smaller devices, reducing size and cost.
“Sumitomo Electric’s GaN-based power devices combined with Xilinx’s SmartCORE IP will demonstrate the world’s next generation of highly efficient solutions for the wireless market,” adds Nobu Kuwata, general manager of Technology and Marketing Strategy Department at Sumitomo Electric Device Innovations, Inc. “Sumitomo Electric is committed to developing the products necessary to meet the requirements of our customers offering smarter solutions.”
