Abstract
A portable lamp, especially for mounting on the head of the user, includes an adjustment collar designed to ensure displacement of the reflector causing a variation of the light beam focus, and operation of the bulb switch. The lamp comprises a single casing having an insulating body subdivided by an intermediate wall into a first rear compartment housing the power supply unit, and a second front compartment housing the bulb and the adjustable focusing device. The wall is provided with a communication orifice between the two adjacent compartments, and with a fixed sleeve to house the bulb. The switch is composed of an elastic contact blade cooperating with a flange of the reflector. Refer to FIG. 1.
