Corning and Osram Opto Semiconductors to Market a Laser and Fiber-based Light Source
LIGHTimes News Staff
November 18, 2014...Corning Inc. and Osram Opto Semiconductors have developed a unique
laser-based light source that employs an innovative glass optical fiber from
Corning that disperses light rather than transferring it. Osram Opto
Semiconductors and Corning Incorporated announced a co-marketing agreement to
promote this light source which will be called the Corning Fibrance
Light-Diffusing Fiber. Fibrance fiber requires the use of a laser light source
such as Osram’s blue and green laser diodes that boast high beam quality
and high efficiency that effectively minimizes temperature increase.
The extremely-thin glass optical Fibrance fiber is optimized for
applications such as automotive interior, consumer electronics, architecture,
and major appliances. The fiber can be curved, contoured, and wrapped around
objects while maintaining bright and uniform light, but corning says it is
nearly invisible when the light source is off. Fibrance fibers can emit clear
colored light up to 50 meters in product length.
“We expect the automotive and consumer markets to be early
adopters of this technology,” said Osram marketing manager, Sevugan
Nagappan. “While Fibrance fiber is ideal for vehicle interior
applications, the design possibilities and product integration opportunities
are truly endless.”
Curt Weinstein, vice president and general manager, Advanced Optics, Corning
Specialty Materials said, “Our long-term goal is to get Fibrance
Light-Diffusing Fiber into the hands of designers and let the capabilities of
the product create new lighting possibilities.”
Osram showcased Fibrance at the Electronica International Trade Show and
Conference in Munich, Germany on Nov. 11-14.
Osram Debuts 20-Chip Blue Laser Diode Module for Projectors
LIGHTimes News Staff
June 17, 2014...Osram Opto Semiconductors has introduced a laser diode with a 50W
optical output. The diode is comprised of 20 blue LED laser chips.
Osram Opto reports that its developers also successfully doubled the
optical output of the individual chips for an overall output of 50
W. The laser diode enables professional laser projectors
achieve a brightnes of more than 2000 lumen with only one component.
Osram says its developers are the first to adapt the "butterfly"
package for projection applications. The laser module package
measures 25.5 by 35 millimeters (mm) and accommodates four copper
bars with up to five blue laser chips connected in series and
operated at 2.3 A each. This laser diode product delivers light
output of 50 W from a typical electrical input of 165 with
wavelengths of 440 to 460 nanometers (nm). It achieves 30 percent
In projectors the blue laser diodes use with a converter wheel to
converts part of the blue light into the two primary colors of red
and green, are used as the light source for laser projectors.
Previous laser projector designs required more than 20 individual
laser diodes to be combined.
Several modules combined in a laser projector can achieve brightness
levels far in excess of 5000 lumen. Osram Opto Semiconductors
optimized the chip parameters to double the single-chip output from
1.6 to 3.2 W and also improved the thermal resistance of the module.
Each specially designed chip with improved optical output power can
help to reduce the price per optical watt. According to the company,
the module also greatly reduces production costs compared to using a
large number of individual TO packages. The radiation from all the
laser chips can therefore be collimated with a single lens array. "The
innovative package simplifies the integration of laser technology
in projectors considerably, enabling a breakthrough in the
projection market," said Stephan Haneder, marketing manager
at Osram Opto Semiconductors.
Volume production of the PLPM4 450 will start at the end of 2014.
Samples will be available from the summer. The Osram Specialty
Lighting Business Unit will also be integrating the multi-chip
package in a new generation of phaser light modules for projection
applications. Phaser in this case is a hybrid word formed from
phosphor and laser. The company says that phaser light modules based
on the multi-chip package will feature a particularly compact design
and will be capable of being used in combination, making them very
easy to integrate in existing projector architectures. The laser
module has an L-50 of up to 20,000 hours depending on ambient
Sharp and Osram Enter into LED and Laser Diode Patent Cross-Licensing Agreement
LIGHTimes News Staff
August 26, 2013...Sharp Corporation of Osaka Japan and Osram GmbH of Munich, Germany have entered into a patent cross-licensing agreement covering LEDs and laser diodes. Terms of the agreement were not disclosed, and the specific patents covered were also not revealed. The cross-licensing agreement grants each company the right to use inventions related to LEDs and laser diodes covered by the patents around the world, which the respective companies own. Sharp and Osram expect that the agreement will invigorate their Research and development and contribute to further advances in LEDs, laser diodes, and related industries.
Sharp is by no means a new entrant into the LED market. Sharp began mass-production of LEDs in 1970 and claims the world's first production of infrared laser diodes for CDs in 1982. Sharp reportedly built up these LED and laser diode technologies over the years. In addition the Sharp says it has recently come out with numerous unique devices, including a high-efficiency, high-brightness 100 W-class LED for lighting, and a red laser diode that can be used as a light source for displays.
Siemens Looks to Spin Off Osram Instead of IPO
July 30, 2012...Instead of a previously talked about IPO for Osram, Siemens announced plans to spin off the company. Osram ram includes: Osram Opto Semiconductors, the optoelectronics subsidiary of Osram, that manufactures optoelectronic semiconductor components including LEDs and high power laser diodes. The new plans came after the company missed analyst estimates of Euro 1.32 billion, due to an accounting charge relating to Osram. Also Siemens reported that new orders were down 23 percent in Q3 2012 compared to Q3 of last year.
Siemens CEO Peter Loscher said,
“Since market conditions continue to be volatile for an IPO, we have decided to pursue a spin-off to our shareholders as the most probable part of divestiture.”
Loscher noted that demand from China was slowing and said he doesn't expect recovery until 2013 or later.
“Our focus above all is on increasing our productivity and efficiency,” he added.
ISCAS to Receive Aixtron MOCVD Systems for Electronics and Red LEDs
CompoundSemi News Staff
February 21, 2011...Aixtron SE reports that it has received a new order for MOCVD reactors from existing customer, the Institute of Semiconductors Chinese Academy of Sciences (ISCAS) in Beijing. The orders is comprised of one AIX 200/4 in the 3x2-inch wafer configuration and one AIX 2600G3 IC in the 8x3-inch wafer configuration.
The institute placed the order during the third quarter of 2010. The systems delivered in the second quarter of 2011, will be used for production of electronic devices and red LEDs. The local Aixtron support team will commission the new reactors in a dedicated facility.
A ISCAS spokesperson commented, “This is a repeat order for us and over half a decade we have formed a good long-term relationship with the Aixtron group. We are convinced that these Aixtron systems will help us to achieve a very high standard of results for R&D in these key technology areas. We have been impressed in initial trials how effectively and easy it has been to scale up device processes from our existing deposition systems to the new Aixtron systems."
