Here is a simple tester for Hobbyists. This LED Component tester can test the integrity of electronic components from resistors to ICs before soldering. It reduces the job of testing the components ...

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 ...

High-brightness LEDs, with independent delay and duration, find use in a visual-inspection application. This circuit is not complex, but it saved the day in an application involving visual inspection ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

The ubiquitous triac dimmer can still work with LED lamps, thanks to new ICs. Energy-efficient lighting is in the headlines as we approach the date at which federally mandated efficiency levels for ...

The function of an LED is to emit light when the device is forward biased within its operating range, and it’s known by most people that an LED can also operate as a photodiode. Perhaps some readers ...

LED technology offers significant benefits in the established streetlight market. Up until a few years ago, this market relied upon mature sodium and metal halide lighting technologies. These lighting ...
