2. Description of the Related Art FIG. 6 is a view showing an arc tube 17 of a halogen lamp. The arc tube 17 is provided with a filament 19. Both ends of the filament 19 are connected to a molybdenum foil 18, and the molybdenum foil 18 is connected to an external circuit by an electric wire. The molybdenum foil 18 is
1 sealed. The filament 19 is sealed in the arc tube 17. A halogen is sealed in the arc tube 17. Exhaust from the arc tube 17 and sealing of halogen are performed from an exhaust tube (not shown), and after the operation such as exhaust is completed, the exhaust tube is blown and removed. After the exhaust pipe has been blown, a trace of the connection of the exhaust pipe remains as the exhaust pipe fusing section 59. The exhaust pipe fusing section 59 is shown in FIG.
As shown in FIG. Alternatively, it may be wavy. Thus, while the other surface of the arc tube 17 has a smooth tubular shape, the exhaust pipe fusing portion 59 has a complicated shape. For this reason, the exhaust pipe fusing section 59 may serve as a lens, and the light emitted from the filament 19 may be condensed by the exhaust pipe fusing section 59. That is, due to the presence of the exhaust pipe fusing portion 59, the light emitted from the arc tube 17 may not be emitted uniformly.

FIG. 2 is a sectional view taken along the line AA of FIG. FIG.
As shown in the figure, the exhaust pipe fusing portion 53 of the arc tube 23 is arranged so as to avoid the arc tube 21 and the arc tube 25. In the case of FIG. 2, the exhaust pipe fusing portion 53 is disposed between the arc tube 21 and the arc tube 25. That is, the exhaust pipe fusing portion 53 is directed to the range of B1, and the exhaust pipe fusing portion 53 is not directed between B2 and B3. If the exhaust pipe fusing portion 53 is directed to B2, the filament 3 of the arc tube 21
There is a possibility that the light is condensed by the lens function of the exhaust pipe fusing portion 53 for 1. When the light is condensed on the filament 31 by the exhaust pipe fusing section 53, the filament 31 is overheated. Thus, filament 3
If 1 is overheated by the light condensing by the lens action,
The filament 31 is deteriorated, and the life of the filament 31 is shortened. Similarly, the exhaust pipe fusing section 53 is
If the filament 35 is disposed in such a manner, the filament 35 is overheated, and the life may be shortened. Therefore, the exhaust pipe fusing section 53 is arranged so that the arc tube 21 and the arc tube 25 do not face in a certain direction. Similarly, the arc tube 21
The exhaust pipe fusing portion 51 is disposed between the arc tube 23 and the arc tube 25. Further, the exhaust pipe fusing portion 55 of the arc tube 25 is disposed between the arc tube 21 and the arc tube 23.

FIG. 3 shows a case in which the exhaust pipe fusing portion 53 of the arc tube 23 is arranged to face any one of B4. Further, a case is shown in which the exhaust pipe fusing portion 51 of the arc tube 21 and the exhaust tube fusing portion 55 of the arc tube 25 are also arranged outward. In FIG. 2, the exhaust pipe fusing portions are all directed inward, and in FIG. 3, the exhaust pipe fusing portions are all directed outward, but one of them is directed inward and one is directed outward. It does not matter. In addition, any of the exhaust pipe fusing sections is shown in FIG.
As shown in FIG. Because, as shown in FIG. 3, when the exhaust pipe fusing portion faces outward, light is condensed by the lens function of the exhaust pipe fusing portion directly to the outside of the lamp. This is because uniform emission of light cannot be performed. As shown in FIG. 2, when the exhaust pipe fusing portion is located between the other arc tubes, even when non-uniform light emission is performed from the exhaust pipe fusing portion, 2
Because it is emitted outside after passing between two arc tubes,
Non-uniformity will be reduced. Further, the appearance is impaired if the exhaust pipe fusing portion faces outward, but the aesthetic appearance can be maintained if the exhaust pipe fusing portion faces inward as shown in FIG.

The three arc tubes are electrically connected in parallel and connected to the base 13 by electric wires (not shown). 1 is a central axis of the outer tube 11, that is, CC.
It is a tube axis. The tube axis of the outer tube 11 and the three arc tubes are equidistant, and the distance between the arc tubes is also equal.
Three arc tubes are installed so as to be parallel to the tube axis. As described above, by emitting light with a plurality of arc tubes, the high-temperature portion of the outer tube is dispersed and the local temperature situation of the outer tube is suppressed as compared with the case of emitting light with one arc tube. Can be. For this reason, it is possible to prevent the outer pipe from being cracked due to thermal shock such as water injection or rapid cooling.

As described above, the halogen lamp of this embodiment is provided with the sealing portions at both ends and has one inside.
The filaments of the exhaust pipes are arranged in parallel so that two or more arc tubes are filled with a halogen gas and have an exhaust pipe fusing section at the center so as to be electrically connected in parallel. It is characterized in that it is installed so that it does not face a certain direction of the pipe. As a result, no light is condensed by the lens action from the exhaust pipe fusing portion to other arc tubes, it is possible to suppress mutual heating of the filaments, prevent the filaments from deteriorating, and improve the life characteristics. be able to.

FIG. 5 shows a case where two arc tubes are provided. The exhaust pipe fusing portion 51 may be directed to any range of B7. Although not shown, the number of arc tubes may be five or more. Also, FIG. 1 shows a case where the exhaust pipe fusing portion is located at the center of the three arc tubes. However, it is preferable that the exhaust tube fusing portions be located at different positions instead of at the center. This is because the places where light non-uniformity occurs due to the exhaust pipe fusing portion vary.
