LEDs form an inevitable part in the modern electronics as simple indicators to optical communication devices. Light Emitting Diodes exploit the property of the p-n junction to emit photons when it is ...

To measure a zener diode’s breakdown voltage, you need a dc voltage source whose voltage exceeds that of the zener voltage. In Figure 1, resistor R SER provides voltage drop between V IN and V ZEN. In ...

LED driver designs can deliver flicker-free and fast startup dimming performance while still providing high power factor and efficiency, writes Rich Miron Dimming performance of LED lamps in legacy ...

While addressable LED strips are all the rage, [Mike] from [mikeselectricstuff] has been working on an installation using the more basic two-wire strips that are simply controlled via PWM dimming.

In this article, I would like to talk a little bit about LEDs, including why they will become the lighting source of choice, how to power them and also, how to protect them from the hazards they face ...

Infrastructure projects like the Tokyo Gate Bridge are now turning to LED lighting because of its economical and environmental advantages. But these devices still need the right current-limiting ...

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 ...

The human eye is as comfortable with white light generated by diode lasers as with that produced by increasingly popular light-emitting diodes, according to new tests. Both technologies pass ...
