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 ...

Since the earliest versions of indoor LED light bulbs were developed, their designers have faced a variety of technical challenges. These include AC-to-DC power conversion, thermal design/heat-sinking ...

A miniaturized driver manages red, green, blue, and white LEDs for maximum impact with minimal system CPU burden.

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

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 ...

From International Rectifier, the IRS254x is a series of high-voltage, high-frequency buck regulator controllers for ac-dc offline, nonisolated applications requiring multiple LED circuits or ...
