A modification of the current-control circuit in a low-voltage LED system allows use of a chopped supply voltage to modulate the LED intensity. The circuit prevents inrush current to the decoupling ...

Dimmable LED drivers have stability problems at very low light levels. This article will examine the reasons and propose a solution to the problem. It will not cover triac dimming since instability at ...

To simplify incandescent-like LED dimming – where colour temperature (CCT) falls with intensity – Dialog Semi has introduced a single chip dual output power converter that needs no microcontroller.

American Lighting, Inc., a leading manufacturer of high-quality lighting innovations for residential, commercial, and specialty projects, announces the launch of its NAVI Dim Series and NAVI CCT ...

Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...

Maxim Integrated Products announces the MAX16841, an offline LED driver that enables flicker-free dimming from maximum light intensity down to zero with leading-edge (triac) and trailing-edge ...

Fig. 1: The dimmer circuit schematic showing the filtering capacitors. Rob Atkinson, K5UJ, is an engineer out of Saint Charles, Ill., and one of the many readers who enjoy the DIY projects we feature ...

In theory, a LED light should last for ten years or so, unlike the typical 4W incandescent lamps used in night lights that seem to burn out in only a few months. But as engineer and founder of the ...

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components ...

Originally hailing from Troy, Ohio, Ry Crist is a writer, a text-based adventure connoisseur, a lover of terrible movies and an enthusiastic yet mediocre cook. A CNET editor from 2013 to 2024, Ry's ...
