Streak Cameras Improve Materials Research
Dec 1, 2012 — New calibration options enable significant improvements in the accuracy of new and old devices, which could mean big advances in materials for LEDs and lasers. LEDs have numerous advantages over traditional light sources such as halogen or energy-saving lamps. They use electric power efficiently and, employed in combination with various-colored bodies, can be designed to provide an almost natural light. They are also completely jitter-free. ZnO has shown potential as an active material f...
Siemens Unit Sets Record
Mar 1, 2012 — Osram, a subsidiary of Siemens AG of Munich, has developed an organic LED (OLED) that generates 32 lm/W, making it more efficient than a halogen lamp. Osram researchers have produced a flexible OLED that emits white light from a surface measuring...
OLED Achieves 32 Lumens Per Watt
MUNICH, Jan. 27, 2012 — Siemens AG announced that its Osram subsidiary has set a new efficiency record, developing a new organic LED (OLED) that generates 32 lumens of light per watt, making it more efficient than a halogen lamp. Osram researchers have now produced...
Design Possibilities with LEDs
Jan 1, 2006 — Full-color LED displays evolved out of a need for much brighter and more rugged displays than were possible using other technologies. First introduced in the mid-1990s, they now are a mainstream product for large events as well as for large, fixed...
Students Build a Rover for Remote Mine Exploration
Jan 1, 2005 — Because exploring mines can be dangerous, two students at the University of Arizona in Tucson devised an 18-in.-long, radio-controlled rover to remotely investigate a mine's nooks and crannies. Equipped with a pan-and-tilt video camera and two 12-V...
