電極３ｂはモリブデン箔５ｂ。Conventionally, high pressure discharge lamps have been used on roads, sports grounds, gymnasiums, factories, etc. In recent years, high-pressure discharge lamps have attracted attention as power-saving light sources because they are compact and highly efficient, and their use is gradually spreading to commercial facilities. However, for use in commercial facilities, an instantaneous restart is required, which is different from the above-mentioned road use, so a heating element is installed near one electrode in the arc tube, and a lighting tube is used as a starter. A high-pressure discharge lamp equipped with a starting aid on the outside of the arc tube has been proposed, and examples of such high-pressure mercury lamps include those shown in FIGS. 1 and 2. In the figure, 1 is an outer tube formed into a substantially spherical shape, and 2 is an arc tube housed within this outer tube 1. As shown in FIG. Further, 3a and 3b are a pair of main electrodes provided at both ends of the arc tube 2, and 4 is a heating body provided near the main electrode 3a. The main electrode 3a is connected to the outer tube 1 through a molybdenum foil 5a and a lead 6.
connected to the stem lead 7a which is hermetically inserted into the
Furthermore, this stem lead 7a is connected to a base 11 via a series lead 8, a stabilizer 9, and a lead 10. On the other hand, the main electrode 3b is a molybdenum foil 5b.

に設けられたケース２３内に収納されている。It is connected to the stem lead 7b via the lead 12 and support frame 13, and further connected to the base 11 via the lead 14. Further, one terminal of the heating body 4 is connected to a molybdenum foil 5.
a, the other terminal is connected to the terminal 19 of the lighting tube 18 via the molybdenum foil 15, the sudo 16, the stem lead 7c and the lead 17, and the other terminal 20 of the lighting tube 18 is connected to the lead. It is connected to the stem lead 7b via 21. A starting aid 22 made of a molybdenum wire of 0.1.phi. is wound around the outer surface of the arc tube 1, and both ends of the starting aid 22 are connected to a support frame 13. Note that this has the effect of lowering the starting voltage. The inner surface of the outer tube 1 is coated with a phosphor, and the inside is filled with nitrogen. The lighting tube 18, ballast 9, etc. are housed in a case 23 that is integrally provided between the outer tube 1 and the base 11.

続されると、先ず点灯管１８の固定極２５と可動極２６
との間に放電が発生し、加熱体４から電子が放出される
。放電の熱によって可動極２６が変形して両極が接触す
ると放電が停止して加熱も停止するので両極は離れる。In such a high-pressure mercury lamp, when the power supply 24 is connected to the base 11, the fixed pole 25 and the movable pole 26 of the lighting tube 18 are first connected.
A discharge occurs between the two, and electrons are emitted from the heating body 4. When the movable pole 26 is deformed by the heat of the discharge and the two poles come into contact, the discharge stops and heating also stops, causing the two poles to separate.

。At this time, the ballast 9 generates a surge voltage, and the terminal 20 that generates a high voltage is applied to the main electrode 3b. As a result, the electrons emitted from the heating body 4 increase the conductivity between the main electrodes 3a and 3b, and discharge is started to turn on the lamp.

い等の欠点が免れなかった。However, in such a high-pressure mercury lamp, the shadow of the support frame 13 is projected onto the outer bulb 1 while the lamp is lit, and the shadow of the sealing part on the main electrode 3b side of the arc tube 2 is also projected onto the outer bulb 1. There was a problem with uneven light distribution. In particular, when used in commercial facilities, the lamp is installed at a lower position compared to the usage conditions of roads, grounds, etc., so the lamp's internal configuration tends to be affected, which affects the lamp's light distribution and luminous flux. Further, disadvantages such as a large psychological discomfort due to the shadow projected on the outer tube 1 were inevitable.

圧放電灯を提供することを目的とする。This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and it involves installing an arc tube perpendicular to the axial direction of the discharge lamp, and placing a reflector between the arc tube and the stem lead. The purpose of the present invention is to provide a high-pressure discharge lamp with uniform light distribution and good appearance.
以下この発明の一実施例を図について説明する。An embodiment of the present invention will be described below with reference to the drawings.

The arc tube 2 is mounted on a support frame 27 bent into a substantially U-shape so that its axial direction is perpendicular to the axial direction of the discharge lamp passing through the base 11 and the end of the outer tube 1. .

その説明を省略する。Further, the inner surface of the outer tube 1 is coated with a phosphor, and the inside is filled with nitrogen. The arc tube 2 has an inner diameter of 6 wtm, a distance of 16 fins between the main electrodes 3a and 3b, and an internal volume of 0.57 W. The interior of the arc tube 2 is filled with mercury and argon, and the pair of main electrodes 3a and 3b and the heating element 4 are arranged as in the conventional example. It is provided. Each of the stem leads 7a to 7c is hermetically inserted into the outer tube 1, and between the stem leads 7a to 7c and the arc tube 2, a reflecting plate 28 having a convex surface with respect to the arc tube 2 is attached to the support frame 27. It's fixed. The other configurations and connections thereof are the same as those of the conventional example, and to simplify the explanation, the same reference numerals are given and the explanation thereof will be omitted.

板２８の反射光により消滅されて均一な配光となる。The high-pressure mercury lamp constructed in this manner is turned on when a power source is connected to the base 11 to start discharging, as in the conventional example. Since the arc tube 2 is fixed perpendicularly to the lamp axis direction and is provided with a reflector, the outer tube 1
The shadow of the support frame 27 is not projected on the frame 27, and the shadows of other members are eliminated by the reflected light from the reflection plate 28, resulting in uniform light distribution.
