It is well-known that simultaneously mixing two primary-color light sources, such as red and green, creates a secondary color, such as yellow. This mixing process commonly occurs in tricolor LEDs. One ...
(Nanowerk News) The nanotechnology research team led by professors Helge Weman and Bjørn-Ove Fimland at the Norwegian University of Science and Technology's (NTNU) Department of Electronic Systems has ...
CHAMPAIGN, Ill. — A new process for creating ultrathin, ultrasmall inorganic light-emitting diodes (LEDs) and assembling them into large arrays offers new classes of lighting and display systems with ...
The increasing use of color displays in portable devices has spurred a number of semiconductor suppliers to develop driver ICs for white LED arrays. Although white LED drivers have been available for ...
The nighttime twinkling of fireflies has inspired scientists to modify a light-emitting diode (LED) so it is more than one and a half times as efficient as the original. Researchers studied the ...
Most Christmas lights, DVD players, televisions and flashlights have one thing in common: they're made with light emitting diodes (LEDs). LEDs are widely used for a variety of applications and have ...
CFL and LED bulbs are light years ahead of incandescents in the energy efficiency arena. But attractiveness? In most cases, incandescents still win. LEDs are more pleasant than CFLs, but as Yumi Kori, ...
