OSRAM develops direct emitting green InGaN laser with 50 mW
OSRAM Opto Semiconductors has achieved a major breakthrough in the laboratory with its direct emitting green indium-gallium-nitride laser. It already achieves an optical output of 50 mW and emits light in true green with a wavelength of 515 nm. Compared with semiconductor lasers based on current technology that operate with frequency doubling, direct emitting green lasers are more compact, offer greater temperature stability, are easier to contro...
Active matrix OLEDs feature excellent optical performance under extreme viewing angles,
CMEL offers active matrix OLEDs with unbeatable optical performance, even under extreme viewing angles, characterize OLEDs. With an active area of 165x99mm the 7.6in P0760WVLB-T (CM02013) is currently the largest available active-matrix OLED from CMEL. With a maximum thickness of only 5.4mm, contrast ratio of 30,000:1, specified life time to half brightness of 30,000 hours and 16.7 mio. colors it is suitable for many industrial applications.
Super low-profile OLED developed in research project
The OLED prototypes that OSRAM Opto Semiconductors has developed as part of a research project are large transparent light sources only a few hundred micrometers thick. Thanks to new technology these organic light emitting diodes do not need separate encapsulation and can be made incredibly thin in any layout. The transparent test samples have a luminous area of 210 cm² and are already showing the enormous potential of OLED light sources. They o...
OSRAM Opto Semiconductors LEDs Enhance Headlights in New Audi A8 Sedan
In the new Audi A8, light emitting diodes from OSRAM Opto Semiconductors are responsible for the low and high beams as well as for other specific lighting functions. Apart from their efficiency and long operating life, LEDs offer enhanced driver safety through improved visual contrast, warmer color temperature, and active electronic control.
California Micro Devices Presented High Brightness LED Protection Devices at SIL 2010
California Micro Devices showcased its innovative LuxGuard family of turnkey solutions for ESD (electrostatic discharge) protection and thermal management for high power, high brightness LED lighting applications at the Strategies in Light Conference and Exhibition 2010 at the Santa Clara Convention Center in Santa Clara, California, on February 10th through 12th.
Efficiency record with flexible OLED
OSRAM has recorded yet another important success with regard to research in the field of organic light diodes (OLED). The company’s researchers have developed so-called “flexible” OLED, which attain an efficiency of 32 lm/W – which is a record value. In so doing, after the rigid OLED, OSRAM has now also reached an important milestone on the road to broad commercial application for flexible OLED.

LED Driver Controller from Diodes Handles More Demanding Lighting Applications
By extending input voltage operation from 60V down to as low as 5.0V, the ZXLD1371 LED driver controller from Diodes Incorporated has been designed to handle as broad a range of applications as possible, including those subject to the greatest variance in input voltage, such as automotive lighting and 12VAC powered systems. Its ability to control an external driver FET in buck, boost and buck-boost driver topologies makes it an all-in-one soluti...
Shin-Etsu Chemical develops new generation of low refractive index silicone encapsulating material that considerably improves the reliability of high brightness LEDs
Shin-Etsu Chemical Co Ltd has developed a new silicone encapsulating material product for applications in packaging materials for HBLEDs (High Brightness Light-Emitting Diodes), the “KER-7000 Series,” which is a low refractive index (RI)-type that greatly reduces gas permeability. The company is beginning sample shipments, mainly for applications in LED lighting.
