?Dinamos viduje gali buti zenerio diodas:
http://pilom.com/BicycleElectronics/DynamoCircuits.html

A Busch & Müller Dymotec6 bottle dynamo (8 magnetic poles) and a Shimano 
DH-3D71 hub dynamo (28 magnetic poles) were used to determine these values. 
Different dynamos of the same type are expected to perform very similar. 
Please check if YOUR dynamo contains a zener diode that is intended to limit 
the output voltage for use with light bulbs. If so, you need to remove it.
