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 ...

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 ...

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 ...

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 ...

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 ...

ANSAN, South Korea--(BUSINESS WIRE)--Seoul Semiconductor Co., Ltd. (KOSDAQ 046890), a leading global innovator of LED products and technology, announced that it has introduced high-power LED package ...

I made this dimmer circuit because I have a cheap chinese LED lamp that doesn’t have the option to dim its light. It is a simple PWM dimmer built with the well-knows 555 integrated circuit and a power ...

National Semiconductor’s LM3402, LM3404 and LM3405 family of light-emitting diode (LED) drivers are designed to power the 1-W to 5-W, high-brightness LEDs. These LED drivers provide a constant current ...

Researchers at Ben-Gurion University of the Negev have demonstrated a novel way to spy on electronic conversations. A new paper released today outlines a novel passive form of the TEMPEST attack ...

The power generated by a drop of water falling onto a droplet-based electricity generator (DEG) can light up 100 small LED bulbs. (Courtesy: City University of Hong Kong) The motion of water, ...
