This presentation was originally given by Andrew Smith, product manager, LED Lighting at Power Integrations for EDN’s May 2011 live LED event in San Jose. The next free LED event will be part of ...

With their ability to provide efficiency and longevity, LEDs represent the cutting edge of new energy technology, but a simple misstep in the design can cause their life to end prematurely. As this ...

Although Christmas may be several weeks behind us, various colorful LED contraptions can nowadays be found in our houses at any time of year. [Tim] got his hands on an LED curtain that came with a ...

It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillator, ...

As their production costs fall, LEDs are being used more often in applications ranging from handheld devices to automotive and architectural lighting. Their high reliability (operational lifetimes of ...

The typical household LED light bulb is advertised with a 25,000 hour lifespan, which would be more than 20 years at 3 or so hours of use per day. That sounds great, but it seems that a good number of ...

Back to the Future fans, rejoice! Now you can build your very own flux capacitor. Even though you can't time travel, you can still create a time-travel device with the Flux Capacitor with Animated LED ...

First of all, apologies if this is not the appropriate forum for such a thing, but I didn't really think it appropriate to put anywhere else. In any case, I bought 2 30 light strings from the HEB up ...

Schematic and operation of a capacitorless active-matrix micro-LED pixel, where a single memristor (1M) substitutes both the storage capacitor and the driving TFT. The compact 1M cell can be ...

Parallel LED drivers can be used to create the fast, square, high-current waveforms required for automated image processing. And it’s possible to extend such waveforms to higher currents by connecting ...
