What is an LED driver? An LED driver is a self-contained power supply that has outputs matched to the electrical characteristics of your LED or array of LEDs. There are currently no industry standards, so ... What happens if I overdrive an LED? A typical indicator LED will have a spec that represents a typical point along the operating curve. That would look something like “3.3V @ 20mA typical.” Driving this LED above ... Can LEDs be dimmed? It’s useful to think of an LED as a current-driven device. The light output is proportional to the drive current over a decent range. But things go a bit odd ... What are the electrical characteristics of LEDs? It’s useful to think about two main types of LEDs—the familiar indicator LEDs that come in 5mm and 3mm epoxy packages, and “illumination-grade” LEDs, which are high-output devices, designed for ... How do you get more light out of an LED? LEDs are made by a process that deposits the junction materials on a substrate material. One of the limitations of LEDs is that imperfections in the material deposited on the ... What makes an LED such a good colored light source? If you want a colored light, LEDs can’t be beat for efficiency. The process that gives off the light makes light of a certain wavelength, which is a function of ... How do they make white LED light? There’s two main ways to get white light from LEDs:
The first method is to combine light from red, green, and blue colored LEDs. If you get the right mix, the ... Why are LEDs different colors? The color of an LED is a function of the material used to make the junction. There are two main flavors used in visible light LED junctions:
Indium gallium nitride ... What is an LED? Light Emitting Diodes, as the name states, are diodes. A diode is a semiconductor device that permits current flow in one direction. Semiconductor diodes are a junction of two materials. ... Page: 1 | 2 |
