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 ...

The circuit below illustrates powering a LED (or two) from the 120 volt AC line using a capacitor to drop the voltage and a small resistor to limit the inrush current. Since the capacitor must pass ...

Schematic and operation of a capacitorless active-matrix micro-LED pixel, where a single memristor (1M) substitutes both the storage capacitor and the driving TFT. The compact 1M cell can be ...

Teardowns of cheap electronic devices can produce results that are interesting, horrifying, or both, especially when mains power is involved. [bigclivedotcom] gave a minimalist LED lamp his reverse ...

Discover how to build a simple device that converts light into electricity using LEDs and diodes. This step-by-step guide demonstrates assembling an LED-diode cluster, connecting it to a capacitor for ...

A controller IC drives high-brightness LEDs for a variety of indoor, outdoor, and automotive applications. Its LED system design is simplified by the use of an online program. Housed in a 20-pin ...
