news digest ♦ LEDs the heart of Korea’s booming LED industry
Neo Material Technologies Inc. (Neo) has officially opened its gallium tri-chloride production facility in Hyeongok Industrial Zone, in the Republic of Korea.
Following the Company’s acquisition of an 80% ownership in Oklahoma-based Gallium Compounds in August 2011, Neo initiated the design and construction of a new facility in Korea, utilising Gallium Compounds’ technology for the production of gallium tri-chloride in Asia.
This second manufacturing facility is now operational and is strategically situated in the heartland of Korea’s booming LED industry. This new plant will supply Asian markets as well as serve as a back-up for the plant located in Quapaw, Oklahoma. Neo owns 80% of this new production facility with the remaining 20 percent owned by the founders of Gallium Compounds, Greg Evans and Kevin Reading.
“We are extremely pleased with the progress we have made in the gallium tri-chloride market since acquiring a majority stake in Gallium Compounds,” says Geoff Bedford, Executive Vice President and COO. “Our ability to have this new, state-of-the- art plant in operation within seven months is a testament to our ability to execute quickly in a high growth market. This is an important step in our growth strategy for rare metals.”
Neo is a producer, processor and developer of many materials that are used in many of today’s high technology products. These include rare metals products such as gallium, which are used in the wireless, LED, flat panel and solar industries.
Nichia fights back against
Everlight in Germany Yet another nitride LED patent infringement lawsuit has been filed, this time in Germany by Nichia
On April 18, 2012, Nichia Corporation filed a patent infringement lawsuit in Germany at the District Court Düsseldorf against the Taiwanese LED manufacturer Everlight Electronics Co., Ltd. and its German subsidiary Everlight Electronics Europe GmbH. In the lawsuit, Nichia is seeking permanent injunction, rendering account and damages against a white LED product (product number: SMD Low Power LED 61-238/ LK2C-B56706F4GB2/ET) manufactured by Everlight, which Nichia believes infringes Nichia’s YAG patent EP 936 682 (DE 697 02 929). On April 23, 2012, Nichia also filed another patent infringement lawsuit in Germany at the District Court Düsseldorf against the German distributor Future Electronics Deutschland GmbH selling the above mentioned Everlight’s white LED product, which Nichia believes infringes Nichia’s YAG patent EP 936 682 (DE 697 02 929), seeking permanent injunction, rendering account, damages, recall and destruction.
Blue high power laser diode PL TB450
Professional projectors with a luminous flux of more than 1000 lumens are the main area of application for the PL TB450. With its wavelength of 450 nm, Osram says it produces exactly the wanted blue, and with 1.4 W (at room temperature and a current of 1.2 A), the high optical power required. The diode can be used at an operating temperature of 0 to 70 °C.
Its high efficiency of 27 percent means the temperature of the laser will rise only slightly. The efficiency is the ratio of light produced to electrical power consumed. Osram boasts the PL TB450 has a long service life, depending on its use, and up to 10,000 hours at 40° C in continuous operation. The long lifetime of projectors incorporating these devices promotes maintenance-free operation at low energy consumption.
Blue hue high power diode
for laser projectors Osram’s latest indium gallium nitride laser diode is also suited to other applications for high power components. These range from laser systems for stage and decoration illumination to medical applications
Osram Opto has unveiled its new high power laser diode, the PL TB450.
Mounted in a compact TO56 package, the blue laser diode has an optical power of 1.4 W. This makes it particularly suitable for high quality professional projectors.
