Title:
INTERIOR ILLUMINATION DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP3102361
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an interior illumination device for a vehicle to reduce a manufacturing cost through reduction of the number of parts, reduce size as conventional performance is ensured, and besides improve appearance and decorative properties.
SOLUTION: The constituting parts of an inverter circuit 1 are arranged on the under surface of a printed board 3 and soldering is effected on the circuit pattern surface side on the upper side. The electrode pieces of fluorescent lamp sockets 5a and 5b are soldered in a state to make contact with conductors 11a, 11b, 11c, and 11d for a wiring formed on the copper foil part of the printed board 3. Further, by arranging the conductors 11a and 11b for a circuit wiring at the peripheral part of a circuit pattern surface, a conductor for a circuit wiring is eliminated below the fluorescent lamp, a copper foil part on the circuit pattern surface remains in a manner to be positioned facing the fluorescent lamp 2, and the copper foil part is electrically connected to the inverter circuit 1 in a manner to work as the approach conductor 4 of a high frequency lighting circuit. Further, the circuit pattern surface of the printed board 3 is painted in a white color.
