れる。Figures 1 and 2 show a metal halide lamp (hereinafter referred to as a lamp), which is a conventional high-pressure discharge lamp, in which 1 is an outer tube stem, and 2 is a metal halide lamp sealed to the stem sealing portion 1b of the outer tube stem 1. Two stem external leads. One of the stem external leads 2 is connected to the screw portion side of the cap 6, and the other one is connected to the tip end, ie, the center contact portion side of the cap 6. Base 6
is mechanically fixed to the neck portion 4a of the outer tube 4. One of the two stem internal leads 3 is connected to the terminal wire 8 of the arc tube 7 via the ribbon lead 10, and the other is connected to the terminal of the arc tube 7 via the support frame line 12 and the ribbon lead 11. Connected to line 9. The arc tube 7 is filled with a metal halide, mercury, and a starting aid gas, and is held and fixed in the outer tube 4 by a leaf spring 14 and a stem inner lead 3 via a retaining plate 13 and a support frame line 12. Nitrogen gas is sealed in the outer tube 4 to keep the arc tube 7 warm and prevent it from oxidizing.

発光管７内で放電が開始されて数分後に放電は安定し、
ランプは安定点灯状態になる。When a voltage is applied to a conventional lamp with the above configuration through a ballast, the path of the base 6 - stem outer lead 5 IJ - stem 2 - stem inner lead 3 - ribbon lead 10 and the base 6 - stem outer lead 2 - stem inner lead A voltage is applied to both terminal wires 8 and 9 of the arc tube 7 via the path of 3-support frame line 12-ribbon lead 11, and the discharge stabilizes several minutes after the discharge starts in the arc tube 7. death,
The lamp will be in a stable lighting state.

。However, in the conventional lamp described above, when the lamp is lit vertically outdoors with the cap 6 facing upward, water may enter through the cap 6 and accumulate in the outer bulb stem 1. Also, if the above lamp is used at sea and water and salt infiltrate into the outer tube stem 1, the stem outer lead 2 may leak when voltage is applied.
As a result, a crack occurs in the stem sealing part 1b, the airtightness inside the outer tube 4 is lost, and air leaks into the outer tube 4.
flow inside. When air enters the outer bulb 4, the temperature of the coldest part of the arc tube 7 decreases, the vapor pressure of the metal halide sealed within the arc tube 7 decreases, and luminous efficiency and color rendering properties decrease. In addition, the terminal wires 8.9 of the arc tube 7 are oxidized by the intruding air, causing cracks at the ends of the arc tube 7 and non-conductivity between the inside of the arc tube 7 and the terminal wires 8, 9, leading to lamp malfunctions. .

的とする。The present invention has been made to eliminate the above-mentioned drawbacks, and includes a heat-resistant waterproof tube placed over the stem' external lead 2 and an insulating glass coating provided at the end of the stem sealing part lb side of the stem external lead 2. By tightly fitting them together, even if salt water intrudes into the outer tube stem 1, no discharge will occur between the stem outer leads 2, the luminous efficiency and color rendering properties are good, and no lamp defects occur. The purpose is to provide high pressure discharge lamps.

れる。In FIG. 3, la is an integral insulating glass coating made of the same material as the outer tube stem 1, which is hermetically coated at the end of the stem sealing part lb side of one stem external lead 2, and 5 is an integral insulating glass coating on the stem sealing part lb side end of one stem external lead 2. The heat-resistant waterproof tube covered is a silicone tube. In the stem external lead 2, a heat-resistant waterproof tube 5 is hermetically fitted to the insulating glass covering 1a.
