Lighting device`s generator for use in e.g. bicycle, has magnetic pole pair guided in freely rollable manner in inner side of housing that is designed as balloon-shaped hollow body in all three spatial axes along curved inner wall of body

摘要

The generator has a solid spherical permanent magnet (7) guided in a housing (3) in a movable manner, and an induction coil (13) is arranged on the magnet. An electrical current is induced in the coil during reaction of acceleration or deceleration forces on the housing. The magnet has a magnetic pole pair (9, 11) that is guided in a freely rollable manner in an inner side (17) of the housing. The housing is designed as a balloon-shaped hollow body in all three spatial axes along a curved inner wall of the hollow body.
