Abstract

PURPOSE:To decrease the accident or the like of an extra-high pressure mercury lamp and also to exchange it in a extremely short time, by using directly the light, which is generated by the extra-high pressure mercury lamp, for exposing by fixing a flat dashboard in a lamp house. CONSTITUTION:A flat plate 12, which has a rectangluar opening portion 13, which has a side nearly equal to the inside diameter of an extra-high pressure merculy lamp 7 and the other side of a measure of about 10mm., and hole 14 for a setscrew, is made. Then, the flat dashboard 12 is fixed in the cooling water in a lamp house 11, which has a cooling water inlet 11A and an exhaust port 11B, with 4 points of holes 14 for a setscrew by screws 15, so that the long side of the opening portion 13 of the plate 12 crosses at right angle to the long axis of the mercury lamp 7 and the plate 12 is apart at a certain distance (h) from the mercury lamp 7 and, moreover, the dashboard 12 does not touch the mercury lamp 7, and the center (c) of the opening portion 13 coincides with the center of a light source. Thereby, thogh an accident occurs on the light source, as influence on a production line can be restrained to the minimum by exchanging the mercury lamp quickly.
