Patent number: 8288932Abstract: A filament lamp having a filament and an internal lead in which the filament is insulated from contact with the internal lead and prevent from moving during operation to maintain a uniform distribution of light. To this end, the filament lamp includes a luminous tube having an inner wall, and opposing ends on which sealing parts are formed. Multiple filaments are sequentially disposed inside the tube in an axial direction, and internal leads are connected to each filament. An insulating wall is provided along the inner wall of the luminous tube in the axial direction and is disposed around at least one of the multiple filaments. Internal leads running partly parallel to the filaments are positioned between the luminous tube and insulating wall and do not engage the ring supporters of the multiple filaments, which could cause the filaments to move and distribute light in a nonuniform pattern.Type: GrantFiled: September 11, 2009Date of Patent: October 16, 2012Assignee: Ushiodenki Kabushiki KaishaInventors: Akinobu Nakashima, Kenji Tanino

Patent number: 8014652Abstract: A filament lamp includes multiple filament assemblies having filaments connected to paired leads, arrayed in order within a light emitting tube and following a tube axis thereof. Each lead is electrically connected in a seal area. Each filament is powered independently. The light emitting tube includes insulating walls or inner tubes between the filaments and leads that have openings through which the leads pass, and located along the tube axis in proximity to the inner wall of the light emitting tube. Multiple lead accommodation spaces corresponding to the number of leads are provided in the light emitting tube by the insulating walls with each lead passing through an opening in the insulating wall and placed without short circuits in its lead accommodation space.Type: GrantFiled: May 29, 2008Date of Patent: September 6, 2011Assignee: Ushiodenki Kabushiki KaishaInventors: Shinji Suzuki, Akinobu Nakashima, Kenji Tanino
