Embodiment Construction

[0026] Below, refer to Figure 1 to Figure 7 , to describe in detail the preferred modes for carrying out the present invention.

[0027] 【Example】

[0028] An embodiment of the present invention is a light source device in which a positive mark is engraved on the end surface of a discharge lamp cap, and a concave portion is engraved with a reverse mark that is mirror-symmetrical to the positive mark on the end face of the cap holder that holds the cap. , insert a stopper imitating the positive mark between the two concave parts.

[0029] figure 1 It is an external view of a state where a discharge lamp base structure is attached to a base holder of a light source device in an embodiment of the present invention. figure 1 Among them, the base structure 1 is a metal base having a large-diameter cylindrical base portion, a small-diameter base protrusion, and a surface connecting the base portion and the base protrusion. The base holder 3 is a member that holds the lamp via...

Abstract

The present invention is designed to make the base-structure easy to manufacture the lamp-base and base-holder in order to attach the light-source apparatus precisely with checking the adaptability of the discharge lamp. The concaves 14, 34 of mirror symmetry with each other are formed in the base structure 1 and the base holder 3. The concaves 14, 34 can be formed precisely with laser working etc. An electro-conductive plate with thickness equal to the sum of the depth of concaves 14, 34 is punched by a press machine to make a piece 2 fit for the concaves 14, 34 and it is infixed to the second concave 34. The base structure 1 is inserted to the base holder 3 and then the piece 2 infixed in the second concave 34 of the base holder 3 fits to the first concave 14 of the base structure. The piece 2 enables the base structure 1 to align with the base holder 3 and then the both can be attached easily and precisely.

Description

technical field [0001] The present invention relates to a light source device, in particular to a light source device in which suitable discharge lamps for generating ultraviolet rays are easily installed. Background technique [0002] Conventionally, in manufacturing processes of semiconductor devices (ICs), liquid crystal panels (LCDs), and printed circuit boards (PCBs), light source devices having discharge lamps that generate ultraviolet rays are used for exposure. Such as Figure 8 As shown, this type of discharge lamp consists of a quartz bulb 5 , an anode 53 , a cathode 54 , an inner guide rod 55 , an outer guide rod 56 , a closed tube 52 and a base structure 1 . The quartz bulb 5 is composed of a spherical arc tube 51 and two closed tubes 52 . The anode 53 and the cathode 54 are arranged facing each other in the light emitting tube 51 . The anode 53 and the cathode 54 are supported by an inner guide rod 55 and energized. In the closed tube 52, the inner guide rod ...
