A portable lamp, such as a headlamp, having control of the light power without the need for any manual switch is presented. The lamp comprises

Portable lamp comprising a contact-less control device

Portable electric lamp including a lighting module, and a compact case containing a power supply for supplying the lighting module and a limitation device for a current delivered by the power supply, the limitation device including a controlled limitation switch coupled between a reference terminal of the power supply and an output terminal of the lighting module, the limitation device being configured so as to determine a supply voltage between an output terminal of the limitation switch and the reference terminal, and to control the limitation switch so that it is in a closed state when the supply voltage is lower than or equal to a desired voltage.

Portable electric lamp having a current limitation device

The lamp comprises at least one light-emitting diode and an electronic power switch connected in series between a power source and the light-emitting diode. The electronic power switch is controlled by an electronic processing circuit according to the state of a control button connected to a control input of the electronic processing circuit. The button is connected in parallel to the electronic power switch. To detect and reconstitute the state of the button, the electronic processing circuit periodically applies fine turn-off pulses to a control electrode of the electronic power switch.
