We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

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 expectancy ...

The Model 2520 Pulsed Laser Diode Test System performs electrical characterization of laser diodes in either the chip/bar state or in finished products. According to its manufacturer, the 2520 is the ...

Diodes with the wrong markings create extra work for engineers and serve as a reminder that one should never assume anything when troubleshooting design problems Years ago I ran a small electronics ...

The fruit of a collaboration with Labsphere, the 2500INT is a custom-designed integrating sphere optical head that facilitates direct optical measurement of laser diode output power when used with ...

SUMMARY: On April 9, 2012, the U.S. Department of Energy (DOE) published a notice of proposed rulemaking (NOPR) in which DOE proposed a test procedure for light-emitting diode (LED) lamps (hereafter ...
