Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...

Lumissil Microsystems has created a pair of LED drivers that include a 32MHz 8051 microcontroller. “These new controllers enable lighting engineers to create customised dynamic LED lighting animations ...

NEW DELHI: If you are following the LED technology closely, then you might have heard about the term - LED drivers. This is one of the crucial and confusing parts of the LED lighting because there is ...

Light-emitting diodes have become the lighting source of choice for almost all illumination applications. Incandescents, fluorescents, CFLs, and other types are fading away in favor of the almighty ...

A typical LCD consists of liquid crystal material with transparent electrodes and polarizing filters. Applying voltage across the liquid crystal layer allows light to pass through in varying amounts.

There are many applications for LED lighting, from simple incandescent or CCFL lamp replacement to new opportunities in architectural, industrial, medical, and other applications. Each of these ...

Diodes Incorporated, a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today ...

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 ...

Including detailed examples of what works and why, this practical, hands-on book covers the design trade-offs involved in LED driving applications, from low-power to UB-LEDs and beyond.
