Abstract
A portable electric lamp comprises a lighting module with LEDs and user control means connected to an electronic control circuit to define different lighting modes. An optic sensor is housed in the casing near the light-emitting diode LED to transmit to the control circuit a signal representative of the lighting induced by the lamp to automatically regulate the power of the LED according to a predefined threshold.
