Abstract
Method for determining a light-emission capacity of a light emitting diode, referred to as a LED. The method includes the following steps: reverse biasing the LED so as to cause an accumulation of an electric charge by the LED, said LED being subjected to a light source incident to the LED; causing a discharge of the electric charge accumulated by the LED; obtaining a value representing a time taken for discharging the charge from the LED; determining the light-emission capacity of the LED according to the discharge time obtained.
