Compact self-ballasted fluorescent lamp |
摘要 |
Disclosed is a compact self-ballasted fluorescent lamp with higher luminous efficiency than conventional lamps and improved luminous flux rising characteristics at lamp startup equivalent to those of general fluorescent lamps. The compact self-ballasted fluorescent lamp (1) includes an arc tube (2) formed by a bent glass tube (9) covered with a globe (6). The glass tube (9) has a turning part substantially in the middle between its both ends, a first spiral part starting from one end and wound around an axis toward the turning part, and a second spiral part starting from the turning part and wound around the axis toward the other end. The arc tube (2) has mercury enclosed therein in a single form. The glass tube (9) has a substantially circular-shaped cross section and an inner diameter of 7.4mm. The turning part is connected to the globe (9) via a heat-conductive member (15).
