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 ...

Abstract: Electrolytic capacitors are notorious for short lifetimes in high-temperature applications such as LED light bulbs. The careful selection of these devices with proper interpretation of their ...

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 ...

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 ...

Hangzhou, China –Inventronics has announced the release of a new series of LED drivers with a revolutionary design backed by a 10-year warranty. These Controls-Ready, programmable drivers were ...

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 ...

Machine-vision systems use very short flashes of intense light to produce high-speed images employed in a wide variety of data-processing applications. For instance, fast-moving conveyor belts are run ...

Fig. 1: The dimmer circuit schematic showing the filtering capacitors. Rob Atkinson, K5UJ, is an engineer out of Saint Charles, Ill., and one of the many readers who enjoy the DIY projects we feature ...
