Portable electric lamp with a device for controlling a supply current and method for controlling a supply current of such a lamp

摘要

The lamp (1) has a measuring unit (12) measuring a current consumed by a lighting module (2), and a determination unit (22) generating a lighting current set point. A calculation unit (23) calculates a maximum authorized current from a difference between a consumed current and an average current threshold, and calculates a maximum authorized current threshold from the minimum value between the current set point and the maximum authorized current. A limiting unit (24) limits a power supply current to a value lower than or equal to the maximum authorized current threshold. An independent claim is also included for a method for controlling a power supply current provided by an electric power storage unit to a lighting module of a portable electric lamp.
