Research by the Advanced Institute of Technology Photonics group scientists on new approaches to displays and lighting technology were recently awarded the best poster prizes at the European Materials Research Society (EMRS), Strasbourg and the International Conference on Optical, Optoelectronic and Photonic Materials and Applications (ICOOPMA), London.
Cree, Inc., a leader in LED lighting components, today announced it has demonstrated light output of more than 1,000 lumens – an amount equivalent to the output level of a standard household light bulb – from a single R&D LED. Cree’s achievement demonstrates continued leadership in the development of LEDs that can make traditional light bulbs obsolete.
The Toronto Association of Business Improvement
Areas (TABIA) today announced that Toronto is joining Raleigh, N.C. in a
citywide initiative to install light-emitting diode (LED) lighting throughout
its infrastructure. The "LED City" program, which was launched in February by
City of Raleigh officials and LED manufacturer Cree, Inc., fosters
collaboration among municipalities as they deploy energy- efficient lighting
to deliver cost savings and environmental benefits.
Scientists have long known that the human body runs like clockwork, guided by a circadian system that responds to daily patterns of light and darkness. Now a team of researchers is developing a personal device to measure daily light intake and activity, which could allow them to predict optimal timing for light therapy to synchronize the circadian clock to the 24-hour solar day and relieve psychosocial stress.
American Elements announced today the formation of a new product group to manage the production, sales and marketing of its quantum dot nanopowder production facilities. The new division was spun off from the Nanometals™ Group and will operate under the tradename AE Quantum Dots.
OSRAM (Germany) has granted to Seoul Semiconductors against compensation a license to manufacture and sell white LEDs with conversion technology using patents owned by the OSRAM subsidiary OSRAM Opto Semiconductors. In return Seoul Semiconductors granted to OSRAM a license to use housing patents of Seoul Semiconductors. This agreement paves the way for a closer cooperation between the two companies.
Depending on the lens used, the new Golden Dragon from OSRAM Opto Semiconductors is a strong light source for medium or flood beam characteristics with white or colored light. The special feature of this LED is that it makes it much easier to construct luminaires and therefore opens up a much wider range of design options. Minimal dimensions will inspire luminaire designers to create exceptional products for accent lighting or as reading lights that consume only a few watts.
As communities with a commitment to environmental protection, Diex and Hörbranz (Austria) place great value on solar energy and low power consumption for their street lighting. This does not mean that brightness has to be compromised, however, as brilliant street lights equipped with Golden Dragon Oval LEDs amply demonstrate. OSRAM Opto Semiconductors has developed special oval lenses for this application that direct the light accurately onto the street.
Technologies and Devices International, Inc., (TDI), the leading developer and supplier of compound nitride semiconductor materials, today announced another major breakthrough in Gallium Nitride (GaN) compound semiconductor material technology by fabrication of the first epitaxial structures for blue (450 – 490 nm) and green (490 – 510 nm) light emitting diodes (LEDs) grown by hydride vapor phase epitaxy (HVPE).
Airline pilots will have more advance warning of potentially hazardous atmospheric conditions – such as icing – using a new near-infrared Light Detection and Ranging (LIDAR) system developed by scientists at RL Associates in Chester, Pa. The system, now in a prototype testing phase, will also provide better images in foggy, rainy or extremely hazy conditions, making it easier for pilots to take off and land in those conditions, thereby potentially reducing flight delays.
