基台17に取り付けられている。2. Description of the Related Art Generally, a flash discharge tube used for these applications connects an external lead wire to lead rods derived from both ends,
A structure is adopted in which both ends of the flash discharge tube are held by a pair of holders. FIGS. 3A and 3B are a partially cutaway front view and a side view of a conventional flash discharge tube device. In FIGS. 3A and 3B, the flash discharge tube is provided with electrodes 4 and 5 at ends 2 and 3 of a glass tube 1, lead wires 6 and 7 are connected to these electrodes, and xenon is sealed inside. Further, a trigger electrode 10 is provided in close contact with the outer wall surface of the glass tube 1. External lead wires 8, 9 are connected to the lead rods 6, 7, respectively. Then, both ends 2, 3 of the flash discharge tube are held by a pair of holders 13, 14 via adhesives 11, 12, and these holders are attached to the base 17 with screws 15, 16. .

をもろに受け、その結果ガラス管１の一部分に歪力が集
中して50万回閃光以内で早期に破損していた。Problems to be Solved by the Invention The conventional flash discharge tube device having such a structure has the following problems. That is, in general, the flash discharge tube instantaneously discharges the charging energy charged in the capacitor to obtain a flash. For example, in a flash discharge tube for photography installed on a highway or the like, the energy per flash is 350 J and the current pulse width is about 1000 μsec. Calculating the instantaneous electrical input in this case, 350J / 1
000 × 10 −6 sec = 350 KW. When such a large amount of power is consumed instantaneously, the flash discharge tube is subjected to shock breakage and thermal shock generated during discharge. When a shock wave or a thermal shock is repeatedly applied, the glass tube 1 constituting the flash discharge tube is deteriorated and the mechanical strength is reduced. In the conventional flash discharge tube device, since both end portions 2 and 3 of the flash discharge tube are bonded and fixed to the holders 13 and 14 with the adhesives 11 and 12, the flash discharge tube generated by the shock wave and the thermal shock is used. As a result, strain was concentrated on a part of the glass tube 1 and the glass tube 1 was broken early within 500,000 flashes.

In addition, the trigger electrode has come into contact with other metal parts and cannot be started.

である。Means for Solving the Problems A flash discharge tube device of the present invention is a flash discharge tube device having a glass tube, electrodes provided at both ends thereof, and a trigger electrode attached to an outer surface of the glass tube. Only one end of both ends is bonded and fixed to the holder via an adhesive, and the other end is fixed to another holder with a small gap without the use of an adhesive, and does not have the adhesive. In the vicinity of the end of the glass tube on the side, an insulating plate for preventing movement of the flash discharge tube is provided in a direction perpendicular to the axis of the glass tube.

It is absorbed by the entire discharge tube, and the mechanical strength of the glass tube can be maintained for a long time. In addition, near the end of the flash tube without adhesive, an insulator is provided in the direction perpendicular to the axis to prevent the flash tube from moving. Even if the bonding strength of the agent is reduced and the flash discharge tube is insufficiently fixed, large movement of the flash discharge tube can be prevented, and occurrence of optical problems and start-up failure can be prevented.
