UCLA chemists working at the nanoscale have developed a new, inexpensive means of forcing luminescent polymers to give off polarized light and of confining that light to produce polymer-based lasers.
Cree, Inc., a leader in LED lighting components, today announced it has achieved R&D results of 129 lumens per watt for a cool-white LED and 99 lumens per watt for a warm-white LED. These are the best results reported for packaged, high-power LEDs, and they clearly indicate that Cree is extending its lead in solid-state lighting through its continued investments in LED technology.
Firstsight Vision is delighted to have signed an exclusive distribution agreement for the UK with Opgal Optronic Industries Ltd for sales into the Industrial, Security and Defence Markets, This is part of a wider European agreement with the STEMMER Imaging Group.
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.
