    摘要: A fluorescent lamp 1 comprises: a bulb 2 formed by heating bent-portion-formation preordination portions of a single straight-tube-shaped bulb 2a having an external tube diameter of 12 to 20 mm and a tube length of 800 to 2500 mm, forming a plurality of bent portions 2c and straight tube portions 2b adjacent to the bent portions 2c by bending processing, such that the straight portions 2b are disposed generally within the same plane by way of the bent portions 2c, forming in close proximity a pair of end portions 2d and 2d with electrodes 5 and 5 sealed in so as to form a single discharge path through the straight tube portions 2b and bent portions 2c, forming a phosphor layer 4 on the inner face of the bulb, and sealing a discharge medium including mercury; and a base 6 provided on the end portions 2d and 2d of the bulb 2; whereby thermal deterioration of the phosphor layer 4 formed at the straight tube portions 2b is reduced so deterioration of the initial light flux is suppressed, allowing lighting at higher efficiency. According to the above configuration, a fluorescent lamp which is compact and capable of light with high efficiency, and with improved light output properties, and a light fixture using this fluorescent lamp, can be provided.
