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 ...

LEDs for lighting are found anywhere from DIY IoT modules to commercial lighting applications and the cabins of airplanes. To run properly, these critical lighting devices require a precise balance of ...

Fig 1. This voltage regulator circuit (a) uses green LEDs as both the stabilization elements and as the voltage indicators at the front-panel switch (b). Fig 2. The addition of resistor R4 to the ...

I'm wondering what the generally accepted rules are about what the maximum draw on a motherboard's led connectors is. I'm thinking about hooking up 2-3 leds per function (hdd, pwr, etc) and want to ...

This is a fairly long post, so bear with me- I just want to be clear on everything. It would be easier with pics, but unfortunately I'm at work. There are actually 2 somewhat related questions. I know ...

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 ...

Cree, Inc. announces the availability of brighter Cree® XLamp XT-E and XM-L High-Voltage LEDs to provide manufacturers more efficient, cost-effective components. Cree, Inc. announces the availability ...
