Abstract

PURPOSE:To suppress the increase of lamp voltage during lighting, by making the distance between the point where a start assisting member will depart from the surface of a light emission tube and the electrode in the light emission tube or a heat-resistant metal belt. CONSTITUTION:The distance between the point where a start assisting member 12 will depart from a light emission tube 1 and an electrode 6, or the distance between the start assisting member 12 and a heat-resistance metal belt 18 is made longer than 0.5cm preferably longer than 1.5cm. With such arrangement the abrupt increase of lamp voltage during lighting can be prevented.
