Infrastructure projects like the Tokyo Gate Bridge are now turning to LED lighting because of its economical and environmental advantages. But these devices still need the right current-limiting ...

VCC has designed a series of LED sockets that feature a built-in current limiting resistor to provide optimal LED performance. VCC has designed a series of LED sockets that feature a built-in current ...

[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 ...

This slideshow is based on the LEDs Design Ideas Collection, a collection of LED-related reader submitted circuits and design applications that have appeared in EDN's 'Design Ideas' section. Here you ...

This application note provides a practical guideline of TRIAC dimmable LED bulb board design. Passive and active bleeder design guides detail how to maintain latching and holding current without ...

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 ...
