Abstract
The battery powered lamp or torch comprise a lamp head (1) supports a reflector (20) for a filament bulb (3) both of which are behind a protective glass (4). This reflector has a paraboloid shape with a focal point (10) at the bulb filament. The reflecting surface is defined by two circles (7, 8). A second reflector (21) is mounted inside the first and has its focal point (10) at the bulb filament. This reflector is able to turn w.r.t. the first reflector around an axis (22) passing through the bulb filament. This is performed by shafts (23, 24) turning in supports (25, 26) and by use of a knurled knob (27) external to the lamp. The lamp is able to illuminate in two directions simultaneously.
