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 ...
Driver circuits are available in a variety of topologies. These include series (switch-mode) drivers, and parallel (non-inductor) drivers. How LEDs are driven depends on the level of efficiency ...
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 ...
High-powered LEDs are used in a growing number of applications, including automotive lighting, camera-phone flash, entertainment lighting, location lighting, landscape lighting, flashlights, bicycle ...
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) ...
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 ...
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 ...
LifeSafety Power’s ProWire now includes magnetic, LED light strips for the E6, E8 and E12 products, a free, value-add component that brings instant illumination to enclosures to assist with installing ...
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, ...
