Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components ...

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 ...

Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...

1. Bob Pease used an LM334 current source to servo the current from a PNP transistor through an LED diode. The LM334 will draw current into its V+ pin until the voltage on the R pin reaches 0.068 V.

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 ...

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 ...

That means inside every LED bulb are tiny circuit components -- and their soldered contact points -- which are far more vulnerable than the diode itself. The Lighting Research Center of the Rensselaer ...

The lighting industry has been buzzing with news of solid-state light source advancements for several years. As one light-emitting diode (LED) lighting fixture manufacturer puts it, flat printed ...

The simple Diode and LED Tester presented here costs under £5 to build (including all components, the battery and a cheap case) and will indicate the polarity of almost all types of LED and other ...
