Abstract: Since an internal surface of an arc ball receiving recess, which greatly affects the shape of an arc ball, is formed in an arcuate cross section swelling outward, the arc ball can be formed so as to be received in the arc ball receiving recess in front of a focusing opening of a slit shape, whereby the arc ball can be formed in a well-regulated form. Therefore, the arc ball with uniform luminance distribution in the longitudinal direction of the slit focusing opening can be made with certainty in the arc ball receiving recess.

Abstract: In order to ensure high luminance while enabling lighting of a gas discharge tube, an opening area S of a focusing opening was narrowed down into a range of 0.15 to 0.5 mm2. In addition, in order to attain a uniform emission with high luminance, while taking the aforementioned opening area S into consideration, the inventor noted a relation between an opening length A in a longitudinal direction of the focusing opening and an opening length B thereof in a direction perpendicular to the longitudinal direction. Then the shape of the focusing opening was specified by use of an equation to define the relation of B/A and the value thereof was narrowed into a range of 0.1 to 0.5. By limiting the focusing opening by the various parameters in this way, the inventor succeeded in specifying uniform slit light with a good lighting property and with high luminance in the gas discharge tube.
