The traditional way to control the output of multiple LEDs is to dedicate a pulse width modulation (PWM) controller to each LED and use the controller to transform the input voltage to a current that ...
Multi-wavelength visible light emitters play a crucial role in current solid-state lighting. Although they can be realized by combining semiconductor light-emitting diodes (LEDs) and phosphors or by ...
DETROIT -- Your next car’s headlights could be brighter and more focused, illuminating farther down the road but continually shifting to avoid shining into the eyes of other drivers. Multi-LED ...
The growing demand for color displays in cell phones, digital cameras and PDAs has created a huge market for white LEDs as backlights in these applications. Because white LEDs require low dc voltage ...
Luxeon 5050 LEDs from Lumileds are housed in a multi-die package with a round light emitting surface that is just 4.6 mm. High flux at high efficacy enables system designers to reduce LED count and ...
The backlighting system of MacBook Pro keyboards could be upgraded to include TrueTone capabilities, with Apple examining the use of multiple LEDs per key to make the light seem even despite changes ...
This project is so pretty in its own right, it doesn’t need a case! Clocks are a recurring feature among the projects we feature here on Hackaday, with several common themes emerging among them. We ...
