Researchers say they've figured out the cause of a problem that's made light-emitting diodes (LEDs) impractical for general lighting purposes. Their work will help engineers develop a new generation ...

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 ...

Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...

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 ...

I know very little about electronics, but if you give me a schematic and a pile of parts, I can more-or-less assemble them correctly.<br><br>I am trying to build a simple circuit to simulate the ...

The advent of LED lighting in the past few years has now matured to the point where sweeping changes exist in the way we think about illumination. LED lighting was once the darling of scientists and ...

Heat, in particular, can cause these components to quickly break, so installing an LED bulb in a hot corner of your home or in a deep-set socket with poor ventilation can cause the lights to go out ...
