Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To stably light positive columns in a bulb, and to bend and form the bulb into circular shape comparatively easily, in a fluorescent lamp using a rare gas as a discharge medium. SOLUTION: This fluorescent lamp 21 is equipped with a bulb 23 wherein the intermediate part is bent and formed into a circular shape, and the end parts 23b, 23c are linearly formed as so to coincide with or slant inward from a tangent C of a pseudo-circumferential line of the intermediate part, so that both end edges 23d, 23e come close to each other, and a discharge medium composed mainly of a rare gas is enclosed further a fluorescent layer is formed on the internal surface, and a pair of electrodes 25 formed on the external surface of the bulb 23 so as to extend longitudinally in parallel to both ends. The discharge is generated such that stable positive columns are formed in the direction of the section of the bulb, thereby the flicker of brightness can be lowered.  Both end edges 23d, 23e of the bulb 23 can be arranged close to each other by forming the electrodes 25 on the external surface of the bulb 23, thereby the bending shape of the bulb 23 is restricted, which enables the formation of the bulb 23 approximately into the circular shape, without forming the bulb end parts 23b, 23c into a particular shape for gripping.
