A pin 23 with 3a is buried, and this pin 23
A lead wire 7 led out from one end of the arc tube 1 is connected to. The lead wire 7 is inserted into the internal hole of the pin 23, and the pin 23 and the lead wire 7 are connected by welding at the tip of the pin 23. In addition, the peripheral portion 3 of the reflecting mirror 3
A pin 25 with a flange 25a is embedded in the outer wall of a, and this pin 25 is connected to a lead wire 15 led out from the other end of the arc tube 1. This lead wire 15
The connection point between the pin 25 and the pin 25 is the tip of the pin 25.

When embedding pins 23 and 25 in the outer wall of a, reflector 3
is preferably made of ceramics. That is, if it is made of ceramic, drilling for embedding the pins 23, 25 can be done extremely easily. Although it is not impossible to use a glass reflector as in the past, it is difficult to drill holes for embedding the pins 23 and 25, and the manufacturing process is labor-intensive.
本案の構造によれば、反射鏡３と口金とが一体に組み立

むに際しては、綱板に丸孔をあけておき、その丸孔内に
放電灯を挿入して止着するだけでよいので、その作業は
きわめて簡単になる。According to the structure of the present invention, the reflecting mirror 3 and the base are assembled integrally, so that the manufacturing cost is reduced. Furthermore, unlike in the prior art, since the terminals are not exposed on the peripheral edge 3a of the reflecting mirror 3, there is no need for troublesome measures to avoid leakage of high-voltage pulses. When incorporating this discharge lamp into a television device or the like, it is only necessary to make a round hole in the wire plate, insert the discharge lamp into the hole, and fix the discharge lamp, which makes the work extremely simple.

のになるなど種々の効果が得られる。Furthermore, if the terminals of the external connection wires are made into sockets, it is only necessary to connect the sockets to the pins 23 and 25 when connecting the wires, making the connection easy and making it extremely easy to replace the lamp 1. . Furthermore, according to this connection method,
Since the number of electrically exposed parts is reduced, various effects can be obtained, such as increased safety.

効果が大きく、上述の恐れは完全に解消される。In addition, in this type of discharge lamp, a structure in which the reflector 3 is fitted into the inside of the cover member and a pin is provided protruding from the outer wall of the cover member is also considered; Because it is covered, the inside of this cover material becomes hot,
This may shorten the life of the arc tube 1 and the reflector 3. However, according to the present invention, since the reflecting mirror 3 is not covered, the heat dissipation effect is large and the above-mentioned fear is completely eliminated.

る。As is clear from the above description, according to the present invention, pins are provided protruding from the central outer wall and the peripheral outer wall of the reflecting mirror, and the lead wires of the arc tube are connected to these pins. Since the cap and the cap are assembled together, the manufacturing cost is reduced. Furthermore, since the terminals are not exposed at the peripheral edge of the reflecting mirror, there is no need to take any measures to avoid leakage of high-voltage pulses. Furthermore, if the terminals of the external connection wires are made into sockets, it is only necessary to connect the sockets to the pins when connecting the wires, making the connection easy and the replacement of the luminous tube extremely simple. Furthermore, this connection method provides various effects such as safety because there are no electrically exposed parts.
