HEAD LAMP LIGHTING UNIT FOR VEHICLE

摘要

PURPOSE:To improve a rise in the brightness of two head lamps during low speed without being affected by voltage fluctuations applied to the relay coil or the rising characteristics of a dynamo, by designing an improved a head lamp electrical circuit, in the case of a head lamp unit suitable for bycicles. CONSTITUTION:A dynamo 1 comprises two power generation coils 1a and 1b, the coil 1a of which is connected to the primary two head lamps 2 and 5 through the primary and secondary circuits A and B for a direction indication switch 7 of four circuits and three contacts. The other coil 1b is connected to the secondary two head lamps 3 and 4 through one circuit A of a two-circuit/ two contact relay switch 11 and one circuit A of a passing switch 9. The above relay switch 11 is operated by a relay coil 13 connected to the output side of a rectifier 12. One head lamp, either 2 or 5 out of the two head lamps 2 and 5 is flickered by changing over the direction indication switch 7 through a multiple circuit 16.
