Even if you are designing a microcontroller-based LED display system, often it may calls for a manual option to control brightness of the LED display unit. On the otherhand, if it is based on discrete ...

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 ...

The circuit is divided into two portions for easy understanding: Logic control (Figure 1) and LED driver (Figure 2). The circuit is controlled by a momentary push switch. Until SW1 is pressed, the ...

An LED lighting driver chip with in-built 0-10V dimming designed by iWatt does not require a microprocessor to control the dimming function. “We believe this is the first product from anyone with ...

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 ...

Dimming LEDs is an important feature in many of today’s solid state lighting applications. While many implementations for dimming LEDs in the market today rely on PWM modulation of the LED driving ...

Thanks to its novel architecture that implements an average current-mode-control scheme, an LED controller enables a more efficient lighting system that supports complex light patterns. High-power ...
