摘要： PROBLEM TO BE SOLVED: To provide a light source device formed by means of an external electrode type discharge lamp capable of being applid to a large manuscript, obtaining a stabilized light in a moment, and facilitating manufacture. SOLUTION: Two external type fluorescent lamps 10 are disposed in order that apertures 6 are arranged facing to a same direction, and their end parts 4 are linearly connected to each other by a connecting means 1. The connecting means 1 is composed of a lamp holding part holding two lamps 10 and a partition part provided with an electrical insulation, and the two external electrode type fluorescent lamps 10 are able to be lighted by feeding electricity from both of electricity feeding parts 5. Though the light of the two lamps 10 is slightly reduced near the connecting part, the light reduction is suppressed in a small level by using a material excellently reflecting light or a transparent material for the material of the connecting means 1, and by increasing the light in the vicinity of the end parts 4 of the external electrode type fluorescent lamps 10. It is possible that three or more external electrode type fluorescent lamps 10 are linearly connected.

SOLUTION: In an inert gas fluorescent lamp, at least one inner electrode is arranged on an inner surface of a glass tube, and the other electrode is arranged on an inner surface or on an outer surface of the glass tube. A phosphor layer is arranged such that to cover the inner electrode, an aperture for a light extraction is made in the phosphor layer, the inert gas is sealed inside the glass tube, and a dielectric barrier discharge is utilized. An open end of the glass tube is sealed hermetically by a blocking body having a circular cross section and by a sealing part that utilizes a glass with low melting point. The inner electrode communicates with an electrically conductive part, which is formed by covering a part of the inner electrode with the glass of low melting point, and the electrically conductive part communicates with a linking part to communicate with a feeding part on the outer surface of the glass tube through the sealing part.
