In many consumer applications for lighting the cost of existing technology – namely incandescent light bulbs or fluorescent tubes – is so low that LED lighting’s many advantages simply cannot make up ...

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 ...

The new driving force for the growth of white LED lighting is quite simple: lower energy consumption and much lower energy bills. By some calculations, the transition from traditional incandescent and ...

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 worldwide market for light bulbs was a little over 20 billion units for the year 2010 with the LED unit count approximately 0.5% or 96 million units (see Fig. 1). The LED unit count includes all ...

LEDs may be garnering the most headlines these days. But high-intensity discharge (HID) lighting is as popular as ever, too, thanks to its high brightness, excellent color temperature, high ...

The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...

Abstract: The increased popularity of LEDs has challenged LED lighting technology to come up with efficient and cost effective solutions on the design of driver circuits. LED driver circuit uses buck, ...

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 ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

A few years ago, when LEDs first became a viable lighting element, designers rushed to cram the revolutionary technology into traditional lamps with a science-fiction gloss. Since then, designers have ...
