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 ...

A voltage multiplier is applied as a high source impedance, 36V, 300mA, 12W LED driver. The high source impedance is ideal for driving power LEDs because it accommodates variations in LED junction ...

[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 ...

As their production costs fall, LEDs are being used more often in applications ranging from handheld devices to automotive and architectural lighting. Their high reliability (operational lifetimes of ...

In applications ranging from small flashlights to stage lighting systems, high-brightness LEDs can generate usable levels of light with improved efficiency, longer lifetimes, and smaller dimensions ...
