Led Diode Schaltung. Leds emit light when an electric current passes through them. In short leds are like tiny lightbulbs.

Diode types when choosing leds it is necessary o understand the datasheet specifications so that the. The electrical behaviour of an led is quite different from a lamp and it must be protected from passing excessive current usually this is achieved by connecting a resistor in series with the led. Leds that s ell ee dees are a particular type of diode that convert electrical energy into light.
Before a light emitting diode can emit any form of light it needs a current to flow through it as it is a current dependant device with their light output intensity being directly proportional to the forward current flowing through the led.
In short leds are like tiny lightbulbs. Energy star certified fixtures and bulbs provide the same amount of light as incandescent or halogen bulbs while giving you. Never connect an led directly to a battery or power supply. Light emitting diode led schematic symbol and i v characteristics curves showing the different colours available.
