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 ...

When picking an LED bulb, it's best to stick with well-known, reliable brands, even if you have to pay a bit more. For smart ...

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 ...

This is a simple flashing led circuit with 2 leds and 2 NPN transistors. It illustrates the behavior of transistors and capacitors and if you use an oscilloscope it will be very easy to determine what ...

A modification of the current-control circuit in a low-voltage LED system allows use of a chopped supply voltage to modulate the LED intensity. The circuit prevents inrush current to the decoupling ...
