The driving force behind the switch from incandescent lighting to LED technology is to gain power efficiency and longer life. However, the cost of LED assemblies is much higher than incandescent and ...

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 ...

This app note provides a simple circuit to drive high brightness LEDs. It requires minimum external components and it provides both linear and PWM dimming. Ideal for Osram, Lumileds, Cree, and Nichia ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

Typical requirements for industrial LEDs. Designing an LED gate driver using an industrial digital input chip. Ruggedness characteristics of the new gate driver. Industrial control systems universally ...

Nearly all lighting applications today use LEDs. In a relatively short amount of time, they have become established as the preferred choice of illumination. However, in most applications, an LED can’t ...

In this article, we continue our discussion on the importance of grounding when installing LED lighting equipment. Part 1 of this three-part series focuses on the ground plane of the printed circuit ...

Power factor correction, or PFC, is a term used with AC mains powered circuits. A good power factor is when the AC current is in phase with the AC voltage. A pure resistive load has a power factor of ...
