LIGHTING SYSTEM OF MIRROR UNIT FOR SUN VISOR

摘要

PROBLEM TO BE SOLVED: To provide a power supply circuit stabilized for a long period of time using electric charges of a large capacitance capacitor in the charged condition to serve as a power supply for an illumination lamp installed for a sun visor and mounted interiorly on a removable mirror unit. SOLUTION: A large capacitance capacitor 14 to be mounted on a sun visor is used as a power supply for an illumination lamp 6 of a removable mirror unit, and when the unit is mounted on the sun visor electric charges are stored in the capacfitor 14, and the lamp 6 is lighted by releasing the electric charges when the mirror unit is removed from the sun visor.
