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 ...

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. The new, high-performance LEDs leverage ...

Oh God, here we go....<BR><BR>LED's are current devices, not voltage devices. If the LED you have has a 3V voltage drop, then subtract the 3V from your source and use that voltage to calculate the ...

To allow smaller power supplies for compact lamps, Cree has released higher voltage lighting LEDs. With the same footprint as the MX-6 and MX-3 LEDs, the 20V MX-6S and 10.7V MX-3S are designed for ...

[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 ...

True to the history of other types of semiconductor products, LEDs offer better performance at a lower cost with every passing year. So much so, in fact, that the other elements of a conventional LED ...
