指向が制限されるという欠点があつた。 However, such high-pressure sodium lamps use a metal ribbon and a thick stem lead wire, which limits the ability to reduce the diameter of the outer tube, and the use of a stem limits the length of the outer tube. There was also a drawback that there was a limit to how short the structure could be made, and therefore the direction of miniaturization was limited.

線１２によつて支持体７に取付けられている。 As shown in FIG. 1, the high-pressure sodium lamp according to the embodiment of the present invention is provided at both ends of an arc tube 4 in which sodium, mercury, and rare gas are sealed.
Supports 7 and 8 made of a metal such as manganese-nickel alloy or stainless steel and having a substantially rectangular cross section are inserted into cylindrical introduction bodies 5 and 6 made of niobium having electrodes (not shown) at their tips, respectively.
The cylindrical introduction bodies 5, 6 and the supports 7, 8 are connected by welding from the long side direction of the cross section of the supports 7, 8 (see FIGS. 3 and 4). Third
In the figure and FIG. 4, 14 indicates a welding location. The other end of the support 7 is inserted into the exhaust pipe trace 3 of the straight outer tube 1 made of aluminoborosilicate glass, and is connected to a lead wire 9 made of molybdenum.
one end is connected. One end of a lead wire 10 made of molybdenum is connected to the support 8 . The other ends of the lead wires 9 and 10 are hermetically sealed to the sealing portion 2 of the outer tube 1. In order to maintain the sodium vapor pressure within the arc tube 4 at a high pressure, a getter 11 is attached to the support 7 by a ribbon wire 12 in order to maintain the inside of the outer tube 1 at a high vacuum.

な排気速度が得られる。 As described above, in the high-pressure sodium lamp according to the embodiment of the present invention, metal supports 7 and 8 having approximately rectangular cross sections are inserted into the cylindrical introduction bodies 5 and 6, respectively. 6 and supports 7 and 8 are connected to each other, and lead wires 9 and 10 are connected to these supports 7 and 8, respectively, so that the arc tube 4 is supported within the outer tube 1. tube 1
A small outer diameter is sufficient. In addition, the arc tube 4
Because it is supported at both ends, it provides vibration and impact resistance. In this case, if a wire with a large diameter is used for the lead wire 10, vibration resistance and impact resistance can be obtained even if a thin wire corresponding to the necessary capacitance is used for the lead wire 9.
This allows the lamp to be made smaller. In addition, since the inner diameter of the cylindrical introduction bodies 5, 6 and the dimension in the long side direction of the supports 7, 8 are almost the same, the amount of deformation of the cylindrical introduction bodies 5, 6 during welding is small, and therefore Great welding strength can be obtained. Furthermore, when creating a high vacuum inside the outer tube 1, the exhaust spaces 15 between the cylindrical introduction bodies 5, 6 and the supports 7, 8 are large, and the exhaust spaces 13 between the exhaust pipe trace 3 and the supports 7 are also large. large and therefore good pumping speeds are obtained.
次に、本発明の具体的な例について説明する。 Next, a specific example of the present invention will be described.

50cmの高さまで耐えられることが認められた。 Cylindrical introduction bodies 5 and 6 made of niobium and having an outer diameter of 2 mm and an inner diameter of 1.5 mm are provided at both ends of the arc tube 4 made of translucent ceramic, and inside these cylindrical introduction bodies 5 and 6, the vertical length of the cross section is determined. Supports 7 and 8 each having a rectangular cross section with a width of 0.7 mm and a width of 1.3 mm are inserted, and a lead wire 10 made of a molybdenum wire with a diameter of 0.5 mm is inserted into the support 8 made of a nickel-manganese alloy. Lead wires 9 made of molybdenum wires each having a diameter of 0.35 mm are connected to the support 7 to form a mount, and this mount is incorporated into an outer tube 1 having an outer diameter of 14 mm and a total length of 76 mm to obtain the structure shown in Fig. 1. When they produced a 50W high-pressure sodium lamp, they were able to create a compact lamp because they did not use a metal ribbon support plate or a stem, unlike conventional lamps. Also, when I did a drop test on this lamp,
It has been confirmed that it can withstand heights of up to 50cm.

まつた。 In contrast, the conventional 50W structure that supports one end of the arc tube with a metal ribbon support plate and uses a stem.
The shape of the high-pressure sodium lamp was larger than that of the high-pressure sodium lamp of the embodiment of the present invention, and in a drop test, the stem broke when dropped from a height of 12 cm, and the central axis of the arc tube was also misaligned with the axis of the outer tube. It was.
