ELECTRIC BULB TYPE FLUORESCENT LAMP AND LUMINAIRE

摘要

PROBLEM TO BE SOLVED: To provide an electric bulb type fluorescent lamp of roughly same shape as a general lighting electric bulb such as an incandescent electric bulb by reducing a diameter of a part adjacent to a base. SOLUTION: A lighting circuit 16 is stored within a cover 14 provided with the base. A circuit board 24 of the lighting circuit 16 is arranged to oppose to an end part of each tube body 31 largely formed within the cover 14 and composing an arc tube 18. Electric parts 25, 26 are arranged on both side of the circuit board 24. The chip shaped electric part 26 is arranged on the arc tube 18 side of the circuit board 24. The electric part 26 is arranged with being shifted from the end part of the arc tube 18 and a fine tube 41. The electric part 26 is arranged at a position separate from an electrode of the arc tube 18.
