Battery-hand lamp operating method, involves activating illumination source and timer during switching-on of lamp so that electric power is automatically reduced from nominal power level to continuous power level after provided time

摘要

The method involves reducing electric power supplied to an illumination source (4) from a nominal power level to a continuous power level after switching-on a battery-hand lamp (2) by a control electronics (6). The illumination source and a timer (16) are activated during switching-on of the battery-hand lamp so that the electric power is automatically reduced from the nominal power level to the continuous power level after a provided time. The electric power is gradually or continuously reduced, and the illumination source is provided with a filament.
