SINGLE BASE FLUORESCENT LAMP AND ILLUMINATION DEVICE

摘要

To provide a single base fluorescent lamp of a compact self-ballasted type or the like which is capable of providing a peak light beam output when the lame is used in an illumination device. A lamp (1) comprises a light emitting tube (2) having a spiral part bent spirally, a pair of electrodes and a single curved discharge path therein; a holding resin member (3) for vertically installing the light emitting tube (2); and a base (6) for connecting the lamp to an illumination device. The fluorescent lamp can provide the maximum light beam output when the temperature around the lamp reaches a predetermined level equal to or higher than 30°C.
