Part 2: A 60V buck-boost controller drives high power LEDs, charges batteries and regulates voltage with up to 98.5% efficiency at 100W and higher. Part 3: Offline LED lighting simplified: A high ...

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 ...

As their production costs fall, LEDs are being used more often in applications ranging from handheld devices to automotive and architectural lighting. Their high reliability (operational lifetimes of ...

This file type includes high resolution graphics and schematics. LEDs are the most efficient way to turn an electric current into illumination. When a current flows through a diode in the forward ...

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 ...

Time will always be“of the essence” for professional engineers and amateur enthusiasts alike. This can certainly be said about the process of designing circuits involving Light Emitting Diodes (LEDs).

All circuits, analog or digital, have characteristics dependent on the values of their component parts. Invariably, these parts are non-ideal in many ways. Even their most fundamental characteristics, ...

The 555 timer is one of the most versatile integrated circuits available. It can generate PWM signals, tones, and single-shot pulses. You can even put one in a bi-stable mode similar to a flip flop.

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 ...
