The polarity markings on LEDs (Light Emitting Diodes) seem to be a common cause of confusion. The polarity may be indicated by a flat section on one side of the body or by one lead being shorter than ...

Nanoparticle tech could make for brighter, longer-lasting LEDs By Ben Coxworth August 10, 2020 An array of conventional LED diodes, as used within an LED light bulb tarczas/Depositphotos View 2 Images ...

Diodes Inc. has expanded its automotive-compliant LED driver portfolio, adding the AL8891Q synchronous buck LED driver with high-side current sense that drives up to 2 A from a wide 4.5-V to 65-V ...

The AL8866Q, an automotive-compliant LED driver from Diodes Inc., is designed to drive an external MOSFET. The DC-switching LED driver-controller supports buck, boost, buck-boost, and SEPIC topologies ...

Needless to say, we’re fascinated by LEDs, laser diodes, and other blinkies. Although we can get just about any light emitting thing, the data sheets aren’t always accurate or available. For his ...

A study by UC Irvine’s Department of Population Health & Disease Prevention has discovered that LED diodes contain unsafe levels of carcinogenic toxins. While LED’s less energy friendly cousin’s, CFLs ...

In a previous article, we explored the behavior of an LED diode as a small light source. We have seen how important a protection resistor is to light up this component. In this article, we will ...

LED lightbulbs are more energy-efficient than standard bulbs, but that doesn't mean they work perfectly all of the time. Here's how to troubleshoot these bulbs.
