    • PROBLEM TO BE SOLVED: To provide a structure which has fewer attenuation of light emitted from a filament and suitable light-transmitting efficiency even if an insulating tube for insulating the filament and a lead wire is arranged and has a simple wiring structure of the lead wire and hardly damage strength of the insulating tube, in a filament lamp arranged in a light-emitting tube and having a plurality of filaments in which electric power is independently supplied to each filament. SOLUTION: The insulating tube housing the filament where the lead wires are arranged by adjoining each other and electrically insulating the adjacent lead wires is arranged in the light-emitting tube, and a flange is arranged on the insulating tube. The lead wires are inserted into and engaged with an opening by forming the opening on an outer periphery of the flange. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:即使设置用于绝缘灯丝和引线的绝缘管,并且具有简单的布线结构,从而提供一种从灯丝发射的光衰减较少并具有合适的透光效率的结构 引线并且几乎不损坏绝缘管的强度,在布置在发光管中的灯丝灯中,并且具有多个细丝,其中电力独立地供应给每根灯丝。

      解决方案:在发光管中布置有容纳灯丝的绝缘管,其中引线彼此相邻并且相邻导线电绝缘,并且在绝缘管上布置有凸缘。 通过在凸缘的外周上形成开口,将引线插入并与开口接合。 版权所有(C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a lamp device generating no heat in a feeding terminal even when an input electric power is raised and a current flowing in the feeding terminal is increased, and capable of absorbing stress generated when fixing the lamp device to a device by the feeding terminal itself. SOLUTION: The lamp device is characterized by that a plurality of lamps are mutually connected by connecting external lead rods 12 of each lamp 1 respectively having sealing parts 11 in both ends to the common feeding terminal 13, a portion of the feeding terminal 13 connected with the external lead rods 12 is used as a stress absorbing part 131 for absorbing the stress, a current merging part 132 where currents flowing in each lamp merge is formed continuously with the stress absorbing part 131, a thickness of the stress absorbing part 131 is smaller in comparison to a thickness of the current merging part 132 to absorb stress, and a part of an outer periphery of the stress absorbing part 131 is not connected with the current merging part 132.
