The invention relates to a method for determining a light-emitting capacity of a light-emitting diode, referred to as LED. The method includes the following steps: reversing the polarisation (41) of the LED so as to cause the LED to accumulate an electric charge, said LED being exposed to an incident light source on the LED; causing (42) a discharge of the electric charge accumulated by the LED; obtaining (43) a value representing a discharge time of the charge of the LED; and determining (44) the light-emitting capacity of the LED in accordance with the discharge time obtained. |
