The diode or LED to be tested is simply connected either way round between the test probes, and the cathode connection is indicated by the LED closest to that connection illuminating.

Four New Jersey cities have begun testing new street lamps powered by light-emitting diodes. The new LED lamps are expected to reduce energy consumption significantly, have a longer life ...

The numbers you see on the box don't always work out in real life. LED bulbs do last longer but those claims about five to 10 ...

In forward mode, approximately 150 µA flows through the diode, causing D4 to be reverse-biased and holding comparator U1’s inverting input low. This turns off the red LED.

German PV testing equipment supplier, Wavelabs Solar Metrology Systems GmbH, introduced two new solar simulators based on its light emitting diode (LED) flasher technology, one for module ...

FitTech, a provider of LED probing, testing, and sorting equipment, has expanded its footprint in new industries such as compound semiconductor and laser diode testing, where it anticipates double ...

Someone came to me just recently to discuss a power supply problem in which one particular diode would fail shorted following a mechanical drop test of the unit. Over and over again this would happen.

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 ...
