A few years ago, the highest power LEDs you could buy capped out around three watts. Now, LED manufacturers are taking things to ridiculous power ratings with 30, 40, and even 90 watt LEDs. Getting ...

MSI motherboards use light-emitting diodes to report the status of the computer. Most computers have an LED for the power and an LED for the hard drive. If the PC is turned on, the power LED glows ...

There are many power management methods that can be used for LED lighting. You can drive them via a number of dedicated driver ICs available on the market, or even use microcontroller units (MCUs) for ...

In this article, I would like to talk a little bit about LEDs, including why they will become the lighting source of choice, how to power them and also, how to protect them from the hazards they face ...

Thanks to their energy savings, long service life, durability and design flexibility they offer, light emitting diodes (LEDs) are rapidly replacing incandescent and fluorescent technologies in both ...

LED output is a function of the current through it. So to drive the device, it would seem simple enough to set the LED current with a series power resistor. But there’s a problem with this idea. First ...

Recent breakthroughs in LED technology have enabled LEDs with a broad spectrum of light output to be produced and not just the traditional red and green derivatives. Hence the sheer numbers of LEDs ...

National Semiconductor's LM3402, LM3404 and LM3405 family of LED drivers are designed to power the 1-W to 5-W, high-brightness LEDs. National Semiconductor’s LM3402, LM3404 and LM3405 family of ...

DeKingLED announced observations indicating an increased emphasis on the role of safe and dependable power supply integration ...
