Bulb-shaped fluorescent lamp

摘要

A less costly bulb-shaped fluorescent lamp with improved assembly efficiency is provided which prevents the impairment of product quality due to the change in color of a holder or the slipping off of a fluorescent tube from the holder decreased in resin strength. The fluorescent lamp includes a set of fluorescent tubes (1), filament coils (2) disposed at both ends of each fluorescent tube (1), a starter circuit (3) for activating the fluorescent tubes (1), a holder (4) for retaining the fluorescent tubes (1), and a case (5) containing the starter circuit (3). The holder (4) includes holes (4a) for receiving the fluorescent tubes (1), and a recess (4b) defined in a central portion of the holder and extended in the opposite direction of the fluorescent tubes (1).
