SMALL-SIZED DYNAMIC LIGHT Russian patent published in 1994 - IPC

FIELD: lighting engineering. SUBSTANCE: small-sized dynamic light has housing 1 where generator is located. Generator consists of rotor in form of permanent magnet 5 consisting of disk and stator with magnetic circuit embraced by winding whose projection on the plate perpendicular to axis of rotation of rotor has form of incomplete disk and movable device for transmitting external translational motion to the rotor through gear and overrunning clutch. Magnet 5 is shifted relative to magnetic circuit 9 along its axis of rotation. Magnet and magnetic circuit are made of end form at end clearance relative to each other. EFFECT: enhanced efficiency. 7 cl, 8 dwg
