The human eye is as comfortable with white light generated by diode lasers as with that produced by increasingly popular light-emitting diodes, according to new tests. Both technologies pass ...

Solid-state lighting based on light-emitting diodes (LEDs) is the most efficient source of high color quality white light. Nevertheless, they show significant performance limitations such as the ...

The AL8866Q, an automotive-compliant LED driver from Diodes Inc., is designed to drive an external MOSFET. The DC-switching LED driver-controller supports buck, boost, buck-boost, and SEPIC topologies ...

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 ...

The polarity markings on LEDs (Light Emitting Diodes) seem to be a common cause of confusion. The polarity may be indicated by a flat section on one side of the body or by one lead being shorter than ...

The evolution of LED technology has led to the development of several types, primarily inorganic LEDs, OLEDs, and QLEDs. Inorganic LEDs are known for their durability and energy efficiency, making ...

This is part 2 in a series where I explain how diodes, LEDs and solar panels work. See part 1 if you’re a fan of diodes doing weird things. Trump rages after Canada 'disinvited' US from bridge opening ...
