what do LEDs consist of?
Basically, an LED consists of several layers of semiconductor
compounds. Semiconductors, such as silicon, are materials whose
electrical conductivity lies between that of conductors, such as
the metals silver and copper, and non-conducting materials
(insulators) such as PTFE or quartz glass. The conductivity of
semiconductors can be greatly influenced by the specific
introduction of electrically effective external substances (by
means of a process known as doping). The different semiconductor
layers together form the LED chip. The type of structure of these
layers (various semiconductors) has a crucial bearing on the
luminous yield (efficiency) and light colour of the LED.
If a current flows through the LED in the flow direction (from anode + to cathode –), light is created (emitted).
The n-doped layer is prepared by the incorporation of foreign atoms so that there is a surplus of electrons. In the p-doped layer, there are only a small number of these charge-carriers. This produces so-called electron holes (band gaps). When a voltage (+) is applied across the p-doped layer and n-doped layer (-), the charge-carriers move towards each other. At the pn junction, recombination takes place (where oppositely-charged particles combine to form a neutral entity). This process releases energy in the form of light.
Electric properties – why too much current is damaging
If voltage is applied to an LED, the resistance falls to zero. LEDs
are extremely sensitive components, and if the permissible current
is exceeded even by a small quantity, they may be destroyed.
Therefore it is important never to connect LEDs directly to a
voltage source. They may only be connected if a current limiter or
series resistor is built into the circuit. High-power LEDs are
controlled via an electronic ballast that provides a constant
current.
The adjacent graphic shows the circuit required for an optional functioning of the LED. In this case, a series resistor is used as a limiter which controls the forward current IF that flows through the LED. In order to choose the proper resistor, the forward voltage UF must be determined beforehand.
In order to calculate the series resistor RV, you need to know the
total voltage, the forward voltage and the forward current.
