が局部的に異常高温となる現象を生じる。Recently, ballasts and equipment have been made more compact with the aim of conserving resources and energy. If the front surface of the lamp is sealed with shielding glass, the heat radiated from the arc tube while the high-pressure sodium lamp is lit is reflected by the reflective surface of the lamp and reaches the arc tube again. , a part of the arc tube becomes locally abnormally high temperature.

致命的な欠点を引き起していた。Such local overheating of the arc tube results in an increase in tube voltage,
As a result, fatal drawbacks such as increased power consumption, power failure, and shortened lifespan were caused.

A curved light reflecting surface 2 such as a paraboloid or an ellipsoid is formed, and pressure is applied along the direction of the projection axis.l) A ram lamp 3 is attached. Inside the outer bulb 4 of the high-pressure thorium lamp 3, an arc tube 5 made of polycrystalline alumina, single crystal alumina, or other translucent ceramic is provided. is sealed at both ends of the electrode surface, and in the part facing the curved light reflecting surface 2 of the electrode surface and on the opposite side from the light irradiation side, the heat radiated from the arc tube 5 is heated to form a curved light. In order to prevent the temperature of the arc tube 5 from increasing due to re-reflection to the arc tube 6 by the reflective surface 2, a heat-blocking and light-transmitting transparent film 6 made of at least one of indium oxide, tin oxide, and other materials is provided. It is provided.

５欄の透明硝子外管内に設けて４００Ｗの高圧ナトリウ
ム灯を製作した。For example, a polycrystalline alumina arc tube with an inner diameter of 7.5 mm is filled with an amalgam of sodium and mercury and xenon gas.
A 400W high-pressure sodium lamp was manufactured by installing it inside a transparent glass outer tube in column 5.
前記高圧ナトリウム灯を裸点灯した場合、点灯中の発光
管端部の温度は約７００℃であり正常な点灯特性（管電
圧１００Ｖ ）を維持した。When the high-pressure sodium lamp was lit naked, the temperature at the end of the arc tube during lighting was about 700°C, and normal lighting characteristics (tube voltage 100V) were maintained.

立ち消えを生じる結果となった。However, when we installed a high-pressure sodium lamp inside a reflective umbrella, such as the one shown in the figure with a diameter of 380 mm and a depth of 286 mm, and turned it on with the base facing upward, the temperature near the end of the arc tube rose to about 750°C to 850°C. = The riser tube voltage fluctuated within a range of approximately 105 to 120 cm, resulting in one lamp out of 20 lamps going out.

発明の詳細
な説明したように、本発明はランプの管電圧の上昇を制
御することができるので、立ち消えや短寿命化の防止、
消費電力の増加の抑制等をなし得るという大きな利点を
有するものである。As a countermeasure, we conducted a similar lighting test using the same number of high-pressure sodium lamps, which had a transparent film made of tin oxide on the outer bulb and on the part corresponding to the reflective surface of the reflector, and found that no reflection was observed. The heat rays from the light reflecting part of the tube are blocked by the transparent film provided on the surface of the outer bulb, preventing the end of the arc tube from rising in temperature, resulting in a temperature comparable to that when the tube is lit bare. The voltage also remained stable at around 1' OOV, and no lamps turned off or went out.In addition, in the present invention, when installing a rung in a sealed appliance, etc., the lamp temperature rises significantly. Even in such cases, the above-mentioned drawbacks can be eliminated by providing a transparent film that blocks heat rays and transmits light rays on the outer tube portion of the portion where the reflected light gives heat radiation to the arc tube.0Detailed Description of the Invention As described above, the present invention can control the increase in the tube voltage of the lamp, thereby preventing the lamp from going out and shortening its life.
This has the great advantage of suppressing increases in power consumption.
