[origin: WO2009133309A1] A portable electric lamp comprises an LED lighting module 11 and a user control member 13 connected to an electronic control circuit P for defining various lighting modes. An optical sensor 14 is housed in the casing close to the light-emitting diode LED for transmitting, to the control circuit P, a signal representative of the lighting induced by the lamp, in order for the power of the LED to be automatically regulated according to a predetermined threshold.
