In addition, when an enclosed amount of the trivalent of indium halide is approximately 90.0 mg/cc or less per unit internal volume of the arc tube and the rare gas is xenon gas with an enclosed pressure of 2.5 MPa or less, the luminous flux and the light color most appropriate for a light source for motor vehicle headlights are obtained. Furthermore, when the thallium iodide is enclosed, the lamp voltage can be made even higher and the luminous flux can be increased.

Description

V. Description of the Invention (1) Field of the Invention The present invention relates to a technology for using mercury-free metal toothed lamps in general lighting, automobile headlights, and the like, which are combined with reflectors and the like. Description of the related art The conventional metal toothed lamp is a lamp in which a rare gas and a metal toothed (solid) are enclosed in a luminous tube and mercury is added. These enclosures are enclosed for various purposes. 'Rare gases are mainly used to facilitate the start-up of electric lamps and to obtain strong light output power immediately after startup. Metal halides are used to obtain a moderate light output when the lamp is turned on in a stationary state. Power, and mercury is to make the lamp operate in a proper state, but to obtain the necessary very high electrode voltage (lamp voltage). In particular, a high lamp-to-electrode voltage can be obtained by a lamp enclosed in mercury 'to turn on the lamp. Therefore, the lamp is turned on with a small amount of lamp current. As a result, the electrode's thermal load (Joule loss) is suppressed to a small extent, and the lamp can be turned on for thousands of hours for a long time. Specific examples of conventional metal south lamp include, for example, an automobile headlight disclosed in Japanese Patent Application Laid-Open No. 59_111244, which is known to be suitable. In the following, the conventional metal toothed lamp based on this bulletin will be described as shown in FIG. 12. In the 12th figure, 101 is a light-emitting tube using quartz as a material, and 102 at both ends of the light-emitting tube 101 is a packaging portion. 103 is a counter electrode using tungsten as a material, 104 is a molybdenum metal sheet, and 105 is a wire using the same molybdenum metal as a material. The electrode 103 is electrically connected to one end of the molybdenum metal thin film 104 encapsulated in the package section 〇2, and the other end of the key metal sheet 104 is further advanced—electrically {price first read the note on the back ^^ Fill in this page again-> Order II -------- Line-Printed by Employee Consumer Cooperatives, Bureau of Intellectual Property, Ministry of Economic Affairs

Description of the invention (2) Connected to the lead 105 = In the light-emitting tube 101, the foremost end of the electrode 103 is arranged at the distance between the foremost ends, that is, the distance between the electrodes is about 4 2 (mm). LED! 〇〗 The internal volume is about 0.03 (cc) 'and there is about 0.7 mg of mercury (about 1.1 mg / cc per unit of light-emitting tube content), the total amount is about 0.3 mg (per unit) The internal volume of the light-emitting tube is about 12.0 mg / cc). The halide 107 'composed of sodium iodide, sharp iodide and thallium iodide, and xenon at room temperature of 0.7 MPa, which is not shown in the figure, are sealed. among them. As described above, the electric lamp voltage of the metal halide lamp is about 70 to 80v. When the lamp is turned on with an electric power of about 35W, for example, the lamp current becomes about 0,4-0.5 A-this kind of borrowing to obtain a high electric lamp As a result of the voltage, the conventional metal toothed lamp described above can be turned on with a small amount of current, and the conventional metal halide lamp thus has a long life of about 2000 hours. As described above, encapsulation of mercury causes an increase in the voltage of the lamp, thus providing the screen with a long lamp life of thousands of hours. However, on the other hand, since a step of injecting liquid mercury is required during manufacturing, there are disadvantages such as high manufacturing cost. In addition, in recent years, because of the concern for the global environment, it has been desired to have a mercury-free metal oxide lamp. However, if mercury is removed from the conventional metal toothed lamp described above, the lamp voltage is reduced to about 25V. In this case, the electric current of the lamp in the lamp is about 1.5 A, which is about three times that of the conventional metal halide lamp with mercury enclosed. As a result, the electrode's heat load (Joule loss) increases and the electrode's evaporation becomes more vigorous. Therefore, simply removing the paper size from the metal toothed lamp by self-knowledge is applicable to the Chinese National Standard (CNS) A4 specification (21〇X 297). ----------- Install --- (Please Read the precautions of vS before filling out this page) Order:-Line · Printed by the Consumers 'Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 4469 8 8 A7 __B7 V. Invention Description ( 3) As long as the mercury-free electric lamp made of mercury is turned on for dozens of hours, the light-emitting tube will turn black, and there is a problem that it has reached the end of life in a very short time = this problem is the length of the arc (distance between the electrodes) It is particularly remarkable in a so-called short-arc lamp which is, for example, about 10 mm or less. In view of the foregoing, an object of the present invention is to provide a mercury-free metal toothed lamp that can increase the lamp voltage and prolong the life of the lamp, and can increase (or reduce the reduction of the light beam) emitted by the lamp. Summary of the Invention In order to achieve the above object, the present invention is characterized in that a light-emitting tube of a mercury-free metal-compound lamp contains at least a rare gas and a halogenated compound of indium (+ X) InX3 (X: dentin). In this way, a higher lamp voltage can be obtained than the mercury-containing metal toothed lamp in the United States. That is, 'the lamp voltage can be significantly increased compared to the case where InX3 is not contained and the case where InX is a halide InX containing + indium.' Therefore, since the current flowing through the electric lamp can be reduced, the heat load on the counter electrode can be reduced, and the blackening of the light-emitting tube caused by the scattering of the electrode can be suppressed, thereby obtaining a long lamp life. Also, the above-mentioned rare gas contains at least xenon (Xe), and on the one hand, the sealing pressure of the above-mentioned Xe is set to be at least 0 MPa at room temperature, preferably at 0 MPa, and below 2.5 MPa; By further including the second compound, the voltage of the lamp can be further increased, and the total light beam can be increased. In particular, the increase rate of the voltage of the lamp corresponding to the increase rate of the sealing pressure of Xe is greater than that of the halogenation of the indium + 1 valence of indium * Ιηχ. Therefore, by increasing the sealing pressure, the electric lamp can be easily turned.

Description of the invention (6) The sheet 5 is electrically connected to one end of the molybdenum metal sheet 4 enclosed in the encapsulation section 2 with the wire a electrode 3 made of the same molybdenum metal as the material. The other end is further electrically connected to the wire $. Within the arc tube 1, the foremost end of the electrode 3 is arranged at the distance between the foremost ends, that is, the distance between the electrodes is about 4.2 (mm). The luminescence officer 1 has an internal volume of about 〇025 (cc), and inside it is sealed with about 0.2 mg of +3 valent indium iodide 11113 (approximately 8.0 mg / cc per unit of luminous tube content), approximately Halide 7 consisting of 0.19 mg of snails (with a valley volume of approximately 8.0 mg / cc per unit of luminous tube) and approximately 0.16 mg of moth's sodium (approximately 6.4 mg / cc within the unit of light-emitting tube), and The xenon gas at room temperature of 0.7 MPa, which is not shown, is compared with the structure of a conventional metal halide lamp. A major structural feature of the metal halide lamp of this embodiment is that it does not contain mercury and the enclosed indium The iodide is + 3-valent indium iodide Iηΐ3 β. The mercury-free metal halide lamp can be driven with a rectangular wave voltage of, for example, 150 to 250 Hz. In this embodiment, the most amazing part of the mercury-free metal halide lamp formed by sealing +3 valent indium iodide Inl3 has nothing to do with mercury-free, but it is completed with a very high lamp voltage. Light work situation. For example, when the lamp is turned on with 4d W of lamp power, the lamp voltage of the lamp of this embodiment t is about 5 5 V, and when the lamp is turned on with 35 W of lamp power, the lamp voltage is about 50. V. The +3 valent indium iodide InI is removed from the electric lamp shown in this embodiment; the electric lamp formed by 'j' can only obtain about 27 v even if the lamp is turned on with a lamp power of 25 W to 50 W. Left and right lamp voltage = moreover, even if the indium is iodized with + 丨 valent indium in the lamp 446988 A7 V. Description of the invention (7) The substance Ini replaces the +3 indium in the mercury-free metal halide lamp of this embodiment. The moth compound Ink 'its lamp voltage does not reach the lamp voltage of the lamp of this embodiment even when the lamp is turned on with 35 W of lamp power, for example. In this way, 'the high lamp voltage can be obtained by enclosing Inl3, so the lamp of this embodiment can be turned on after hundreds of hours of lighting', and neither the phenomenon of blackening of the light emitting tube nor any substantial Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Change

In the above embodiment, although a mercury-free metal halide lamp containing iodide Ini3 (approximately go mg / cc per unit of light-emitting tube content) sealed with about 0.2 mg of the +3 valence surface is taken as an example, as described in As shown in Figure 2, because its structure can obtain a higher lamp voltage 'by increasing the encapsulation amount of +3 valence of indium ethene compound ιηι3', it can be seen that its start-up is also very beneficial to the service life. Fig. 2 is a mercury-free metal halide lamp according to this embodiment, which increases the enclosed amount of broken compound Inls of +3 valence indium, and performs lamp operation when the lamp power is 35 W or 45 W. Schematic diagram of the relationship with the enclosed amount of +3 valent indium iodide 1013. If the enclosed amount of + 3valent indium iodide 11113 is as much as possible, the lamp voltage becomes higher β. Furthermore, the lamp voltage due to the increase of the enclosed amount of + 3valent indium iodide ιηΐ3 The rising effect can be within the distance between the electric power of the lamp or the electrode, the luminous tube 1, the sealing pressure of the gas milk (Xe), the amount of the building compound or sodium iodide, or the iodine with +3 indium Dagger. At the same time, the type or amount of other illuminants that are enclosed are obtained when the other constituent elements are irrelevant. As shown in Figure 3, if the sealing pressure of xenon gas is high, the national standard (CNS) A4 size (210 X 297 g) of this paper can be obtained ------- I * I. Iki — (Please read the notes on the back before filling out this page) Μδ * • Line · Description of Invention (8) Get high lamp voltage. In addition, the increase rate (slope) of the lamp voltage corresponding to the increase rate of the sealing pressure is greater than that when the iodide InI is enclosed with + 1-valent indium, or when neither Inl3 is enclosed or InI is enclosed. . That is, 'the method of increasing the sealing pressure can increase the lamp voltage even more. Further, "as shown in Fig. 4", if the sealing pressure of xenon gas is increased, the total light beam also increases substantially linearly. Fig. 4 shows the sealing pressure of xenon gas in a springless metal halide lamp using a 45 W electric lamp power point as the embodiment, with the sealing amount of +3 valent indium iodide Inl3 as a parameter ( Relationship between room temperature) and total beam. Surprisingly, in the mercury-free metal halide lamp of this embodiment composed of +3 valent indium iodide ini3m, as the xenon sealing pressure increases, the hot spot (most Two temperature parts: when the arc tube is kept in a horizontal state, the temperature rise of the arc tube 1 is small enough to be negligible. Therefore, the possibility of the arc tube 1 expanding with the increase of the sealing pressure of xenon gas is low as above. As described above, at least xenon gas and +3 valent indium moth compound Ini are enclosed in the light-emitting tube 1; the mercury-free metal southern compound lamp constituted in this embodiment has a temperature of the hot spot if the xenon sealing pressure is increased. The rise does not occur substantially, and the total light beam increases, and if the moth compound Ink of +3 valence indium is increased, the lamp voltage is increased. And these effects can be the distance from the electric power of the lamp or the electrode, the internal volume of the luminous tube 1, the amount of the stilbene or sodium broken compounds, or the indium iodide lnI; and other halogenated ions that are enclosed at the same time. The type or quantity of things, other components are not relevant

In order to make electric lamps practically, the upper limit of the sealing pressure of 'xenon gas in the mercury-free metallization lamp shown in this embodiment is preferably set to 2.5 MPa (room temperature conversion value). If it is enclosed at about 2.5 MPa or more, the structure of the mercury-free metal halide lamp of this embodiment is that in the lighting operation, the airtight state of the interior of the light emitting tube 1 is from the vicinity of the fast-connected portion of the electrode 3 and the molybdenum metal sheet. Leakage is more likely to be inappropriate. A more preferable upper limit value of the xenon sealing pressure is about 2.0 MPa. On the other hand, the lower limit is preferably about 5 to 20 Kpa which can easily turn on the electric lamp. However, when the mercury-free gold bromide lamp of the present invention is used as a light source for a headlight of an automobile that requires light to start in a short time, the lower limit is more preferably about 0 J MPa. Also, in order to suppress or reduce the amount of supplementary light beam by using 11113 encapsulation, it is more preferably set to 0.7 MPa or 1 MPa. Next, the encapsulation amount of the indium reading of +3 valence and the light beam will be described. According to the fruitless metal halide lamp of the present invention, if it is made into a structure in which the indium iodide In% of +3 valent indium is enclosed in a larger amount, a higher electric lamp can be obtained. When the mercury-free metal-purification lamp shown in this embodiment is used as a light source for a headlight of a car, the enclosed amount of the moth compound on the surface of +3 is less than about 900 mg / unit of the content of the light-emitting tube. The constituent of cc is more suitable for the following points. That is to say, most of the currently used south lamp for automobile headlamps can obtain a total beam of about 〇〇〇 (im) with 55 W of power consumption. In contrast to this, if the electric lamp of the present invention is as shown in FIG. 5, the enclosed amount of the moth compound of the +3 price marriage is made to be less than the paper volume per unit of the content of the light-emitting tube.

Schematic diagram of the relationship with the molybdenum in indium of +3 valence. The maximum allowable value in the mercury-free metal halide lamp of the present embodiment is 2.5 MPa (room In the case of temperature conversion value), the encapsulation amount of the molybdenum compound Inls of +3 valence is an amount of less than about mg / cc per unit of the content of the light-emitting tube, and a beam of about 1 100 (1ιη) or more can be obtained. In a structure having a lower sealing pressure, for example, mercury-free in the present embodiment When the preferable maximum xenon pressure allowed in the structure of the metal oxide is 2.0 MPa (room temperature conversion value), it is appropriate for the mercury-free metal halide lamp of the present invention to obtain a beam of about Π 00 (1 m) or more.
