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 ...

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 ...

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 ...

Long used in instruments and computers as visual indicators for signal integrity and operations status, LEDs are ideal choices due to their high reliability, low power use, and ...

An LED's junction-to-ambient temperature thermal resistance is a measure of its ability to dissipate heat from its junction-to-ambient air, which is a function of its chip size and package. In terms ...
