| QD Vision Announces Achievement of 18 Percent External Quantum Efficiency May 16, 2013...QD Vision of Lexington, Massachusetts, a developer of quantum dot based LEDs,
reports having achieved 19 cd/A efficiency and 18 percent external quantum
efficiency. QD Vision’s latest QLED performance results are currently
published in the 21
April 2013 issue of Nature Photonics. In the article, QD Vision reports
achieving 18% External Quantum Efficiency (EQE) with a color saturated red
quantum dot-based LED.
The company claims that this puts QLEDs near the fundamental efficiency
limit of the technology which... Government Subsidies Decrease for China LED Chip Makers; Taiwan LED Chip Makers to Benefit from Reduced Price PressureMay 9, 2013...China's LED chip makers have seen a large decrease in government subsidies
this year, according to an article by Peoples
Daily. Numerous companies have relied on the subsidies to offer lower
prices. The market is currently facing overcapacity.
Companies such as Sanan Optoelectronics which produces LED die and can offer
it at very low prices will be hardest hit. Other companies such as Elec-Tech
which produces LED production equipment will also suffer from the reduced
funding.

New Conductive Die Attach Adhesive Supports Small Die and LEDsMay 9, 2013...Engineered Material Systems, a global supplier of electronic materials for circuit assembly applications based in Delaware, Ohio USA, debuted its CA-105 Low-Cost Conductive LED Die Attach Adhesive. The Conductive LED Die Attach Adhesive is for attaching LEDs and other small semiconductor die to silver and copper lead frames.
The company notes that EMS CA-105 is approximately half the cost of a pure silver filled die attach adhesive. The company says that... Researchers Use Strain Engineering to Improve Green LED Light OutputMay 8, 2013...Researchers from the Chinese Academy of Sciences’ Institute of
Semiconductors, Beijing, and University of Hong Kong have used strain
engineering to improve the light output of Green LEDs. The researchers improved
the light output of a 530nm green LED operating at 150 mA by 28.9 percent [Hongjian Li et al, Appl. Phys.
Express, vol6, p052102, 2013].
The researchers note that green-emitting nitride semiconductor LED
structures tend to suffer from low light output due to the difficulty... Klauf Lighting Introduces Relatively Inexpensive Remote Phosphor LED Light BarMay 2, 2013...After a year of research and development, Klauf Lighting of Lewes, Deleware
has introduced the Klauf light bar. Uniquely, the light bar takes advantage of
remote phosphor technology. The warm white light is also leverages better
dimming technology that is compatible with standard inexpensive dimmers. The
luminaire has an extruded aluminum housing and a yellow-orange diffuser, which
gives the Klauf light bar a distinctive appearance.
Unlike conventional LED lighting that uses blue LEDs packaged with a
phosphor... Dow Corning Wins Two Awards from Lightfair International for Moldable SiliconesApril 25, 2013...Dow Corning accepted two LIGHTFAIR International (LFI) Innovation Awards
Tuesday. Specifically, Dow Corning beat 307 contenders to earn the prestigious
Technical Innovation Award, described by LFI as one of its top honors for
outstanding achievement in design and application. In addition, two products
– Dow Corning MS-1002 and MS-1003 Moldable Silicones – beat 15
competitors to win Best Product in LIGHTFAIR’s Non-Luminous Components
and Specialty Hardware category. LFI granted both awards to Dow Corning in a
well-attended... Epistar Signs LED Collaboration and IP Licensing Agreement With IntermolecularApril 23, 2013...Epistar, Corp. and Intermolecular, Inc. of San Jose, California USA, have
signed a collaborative development program (CDP) and royalty-bearing IP
licensing agreement to increase the efficiency and reduce cost of Epistar's LED
devices. Under this agreement, Epistar and Intermolecular engineers will
together leverage Intermolecular's High Productivity Combinatorial (HPC™)
technology platform for development and manufacturing qualification of novel
materials and processes for advanced LED products.
Intermolecular notes that in the highly competitive LED market, new
technologies created by R&D... Bridgelux and Toshiba Strengthen LED Business and Technology Collaboration with New AgreementApril 23, 2013...Bridgelux Inc., of Livermore, California USA, will be selling its
GaN-on-silicon LED chip manufacturing assets. Along with its manufacturing assets, Toshiba will now employ certain of Bridgelux's relevant employees related to GaN-on-silicon LEDs and they will remain on site at Bridgelux's headquarters in Livermore California.
Toshiba will mass produce the GaN-on-silicon LED chips, and Bridgelux will be able to focus on developing lighting products. The agreement for an undisclosed amount,
further...
