LEDs are diodes whose P-N junctions behave in a non-linear fashion. Very little current flows until the forward voltage is reached. Above this value the current increases exponentially with increasing voltage. LEDs like all diodes conduct in one direction and do not (until the reverse breakdown ...

its electrical and optical characteristics are easily affected by temperature. The threshold voltage and peak wavelength of LED at different temperatures are measured by using a self-made adjustable thermostat to control the
graph between the current and the voltage, in which the electric current is measured with respect to the voltage applied across the device. As it is much easier to control the voltage in the circuit in comparison to the current, hence while plotting the V-I characteristics voltage act as ...
I thought those numbers corresponded to the ambient temperature vs forward voltage graph? Datasheet is unclear on this. I think it is probably at a fixed 25C across the specified current, but normally I would expect both temperature and test current to be given. Quote ...
When current flows through an LED in the positive direction, the voltage generated between the anode and cathode is called the forward voltage (VF). The unit for voltage is volts (V). In the datasheet for example, the characteristics graph of the forward voltage generated with respect to the...
