[Joey] already has his early start on the decorations, with a house-sized light show using LED strips and a laser projector that he built last Christmas. What started off as a thought that it ...

In the image above you can see the silver cylinder which houses the laser diode ... almost like a red LED due to the intensity of the light. The simplicity of this circuit is fascinating.

This could enable new tech for controlling light with light, opening doors to advanced fabrication, imaging, and illumination ...

The interface circuit receives electrical signals. The source drive circuit converts them to optical signals and triggers the LED or laser diode that then sends the light signals to the fiber optic ...

Many people believe that the LED was discovered ... other applications when a light luminescence contact point is used as the light source connected directly to a circuit of modulated current.” ...

A team led by Prof. Sun Haiding from the University of Science and Technology of China (USTC) developed a vertically integrated micro-scale light-emitting diode (micro-LED) array which was then ...

The Federal Circuit’s correction of the district court’s claim construction also led the appellate court to reverse the lower court’s finding that the first reflective layer and substrate ...

The realization of compact and reliable diode-pumped solid-state lasers that emit UV light is now opening ... One popular use is laser direct imaging for printed-circuit-board manufacture.
