A LED light pipe is an optical fiber or a solid transparent plastic rod for transmitting light from an LED mounted on a printed circuit board (PCB) to the user interface. Light pipes transmit up to 80 ...

Part 1 of this three-part series introduced the technical and engineering steps necessary to design an LED display system from individual LED lamps. Part 2 provided the remaining steps needed to ...

Unlike incandescent tungsten-filament light bulbs, high-power LEDs do not radiate heat. Instead, LEDs conduct heat from their PN junction to the thermal slug on the LED package. Because the heat ...
