This is a fairly long post, so bear with me- I just want to be clear on everything. It would be easier with pics, but unfortunately I'm at work. There are actually 2 somewhat related questions. I know ...

High-power industrial Light Emitting Diode (LED) fixtures use series-parallel strings of High Brightness (HB) LEDs to produce superior lighting fixtures compared to traditional, "ballast-based" ...

International Rectifier, IR®, a world leader in power management technology, introduced the IRS2980 high-voltage buck regulator control IC for LED light bulb replacement, LED tube lighting and other ...

In a previous post, I took a look at the falling prices of LED-based lights, using a flame-tip light as an example. (Quick summary: small lights are a significant market in both the US and Europe.

But there’s a problem with this idea. First, the resistor will possibly dissipate a large amount of power. For instance, a resistor used to drop 12 V (a common voltage used for halogen task lighting) ...

[mircemk] built a slick-looking LED tester with a couple handy functions built in. Not only can one select a target current to put through an LED, but by providing a target voltage, the system will ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

Splitting boost and charge-pump stages extends battery life in modern single-cell laptop LED backlight drivers today.

Light emitting diodes (LEDs) are PN junction devices that give off light radiation through electroluminescence when forward biased. They are used as various indicators in aviation, automotive and ...
