no. 1 approach

[0047] The first embodiment of the present invention is configured such that a lamp data display unit 2 is provided on the side surface of the cylindrical base 11 of the cap 1 of the discharge lamp, and the lamp data displayed on the lamp data display unit 2 is read by an optical reading device. (Properties and Specifications of Discharge Lamps) The properties and setting specifications of the mounted discharge lamps are imported into the light source device.

[0048] Such as figure 1 As shown, a lamp data display portion 2 displaying properties and setting specifications of the discharge lamp is formed on the side surface of the large-diameter cylindrical base portion 11 of the lamp cap 1 . and if image 3 As shown, the structure is such that when the small-diameter protruding portion 13 of the lamp cap 1 is inserted into the hole 32 opened on the abutting surface 31 of the lamp cap holder 3 of the light source device to install the discharge lamp, the lamp data display par...

no. 2 approach

[0064] Such as Figure 5 As shown in the longitudinal sectional view of the second embodiment of the light source device of the present invention, the lamp data display part 2 is provided under the cylindrical base 11 of the cap of the discharge lamp, and the lamp data display part 2 is provided on the side of the abutting surface 31 of the cap holder 3 The reading device 4 which reads the data of the lamp data display part 2. By integrating the reading device 4 with the base 3 in this way, the structure of the light source device can be simplified.

no. 3 approach

[0066] Such as Figure 6 As shown in the longitudinal sectional view of the third embodiment of the light source device of the present invention, the lamp data display part 2 is provided on the disc-shaped abutting surface 12 of the cap of the discharge lamp, and the lamp cap holder 3 of the light source device is formed on the abutment surface. In the concave portion 33 on the contact surface 31, the reading device 4 for reading the data of the lamp data display portion 2 of the discharge lamp is provided via the light-shielding space. With such a configuration, the size of the base holder 3 does not change, and the size of the device can be reduced.

Abstract

The invention provides a light source device. The said light source device automatically judges whether the discharge lamp mounted on the light source device is proper discharge lamp , if it is the proper discharge lamp, the service mode and service history of the discharge lamp is administered. The discharge lamp comprises: discharge lamp with lamp head (1) and lamp / data displaying part (2) for displaying the lamp / data associated with discharge lamp on the lamp head (1), the said lamp head (1) composed of cylindrical base (11)of large diameter by sealing one end using disck shaped abutting surface (12) and projection (13) of large diameter by interpenetrating the centre of the disck shaped abutting surface and coaxial implanting ; and lamp head seat (3) for holding the lamp head of the discharge lamp and performing power on, with a reading device on the lamp head seat (3) for reading the date of the lamp / data displaying part (2).

Description

technical field [0001] The present invention relates to a light source device having a discharge lamp for exposing and generating ultraviolet rays in the manufacturing process of a semiconductor device (IC), a liquid crystal display panel (LCD), a printed wiring board (PCB), etc. A lamp data display unit that displays the attributes and setting specifications of each discharge lamp, and is a light source device that can manage the usage status and history of the discharge lamps by reading the attributes and setting specifications. Background technique [0002] Such as Figure 18 As shown, the discharge lamp used in the existing light source device is composed of the following parts: a quartz bulb 5 composed of a spherical expansion part 51 and two closed tube parts 52, an anode 53 arranged oppositely in the expansion part 51, and The cathode 54, the inner guide rod 55 that supports the anode 53 and the cathode 54 and conducts electricity, the outer guide rod 56, and the clos...
