Consumer demand and government initiatives to phase out inefficient lighting technologies are pushing expansion of LED lighting. Designers of these devices must satisfy not only end users, but also ...

Inspired by printed circuit boards, the building block of all electronics, a Dutch designer has created an LED-based light installation that draws upon the familiar etching pattern inside most devices ...

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 ...

LED replacement bulbs include integrated driver electronics employing a variety of circuit topologies. But LED light fixtures frequently require standalone LED power supplies, sometimes called modules ...

Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...

The process of circuit design can cover systems ranging from national power grids all the way down to the individual transistors within an integrated circuit. For simple circuits the design process ...
