WebThe light emitting diode is the most visible type of semiconductor diode. They emit a fairly narrow bandwidth of either visible light at different coloured wavelengths, invisible infra-red light for remote controls or laser type light when a forward current is passed through them. The “ Light Emitting Diode ” or LED as it is more commonly ... WebLEDs (that's "ell-ee-dees") are a particular type of diode that convert electrical energy into light. In fact, LED stands for "Light Emitting Diode." (It does what it says on the tin!) And this is reflected in the similarity between the diode and LED schematic symbols: In short, LEDs are like tiny lightbulbs. WebThis is usually about 20 milliamps for most single color LEDs. To choose the right amount of resistance for the LED, you also need to know what its turn on voltage (Vf) is.

The 60W and 75W bulbs seem to be the most popular ones when it comes to rough service light bulbs. As the filament is stronger, they do require 130 volts, which is 10 volts higher than traditional incandescent bulbs.

http://lednique.com/current-voltage-relationships/resistance-of-an-led/ Series resistors are a simple way to stabilize the LED current, but energy is wasted in the resistor. Miniature indicator LEDs are normally driven from low voltage DC via a current-limiting resistor. Currents of 2 mA, 10 mA and 20 mA are common. Sub-mA indicators may be made by driving ultrabright LEDs at very low current. Efficiency tends to reduce at low currents, but indicators running on 100 μA are still practical.
