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 ...

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 ...

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 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 ...

Although the primary emphasis of this book is on light-emitting diodes (LEDs), this author would be remiss if he did not address the laser diode. In this chapter, we will describe and discuss the ...

One of the questions that hobbyists ask over and over is how to select the value of a current limiting resistor for an LED. Usually the seat of the pants response is: “Subtract 2 V from the supply ...

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 ...
