摘要： PROBLEM TO BE SOLVED: To provide a tungsten halogen lamp and its manufacturing method which is long in life, high in efficiency, and low in price, by preventing oxidation of metallic foil within a period of useful life. SOLUTION: A luminous tube 1 has a spheroid-shape part 1a as a main part. The other end part of the main part has a seal part 2. A filament coil 3 is positioned within the spheroid-shape part 1a and on the center axis of the luminous tube 1, and retained by internal lead wires 9, 10. An infrared reflecting film 4 is formed on an outer surface of the luminous tube 1 except for the seal part 2. A non-formation part 2a of the infrared reflecting film 4 is formed on an outer surface part of the seal part 2 of the luminous tube 1. Metallic foil 5, to which end parts of the internal lead wires 9, 10 are connected, and external lead wires 6, one end part of each of which is connected to the metallic foil 5 and the other end part thereof is led out to the exterior of the seal part 2, are sealed in this seal part 2. In the seal part 2, an infrared reflecting film 4 is formed on each surface of the external lead wires 6 exposed to a gap region 7 not airtight-sealed and of the metallic foil 5.

摘要： PROBLEM TO BE SOLVED: To satisfactorily weld the mutual contact parts of a metal foil and a lead wire and provide a prescribed strength with little dispersion in individual connecting strength by connecting the metal foil to the lead wire by means of simple arc welding, ark welding such as plasma arc or dig arc, or laser welding. SOLUTION: A metal foil 3 part which is the member to be welded of a mount structure 2 is welded to an internal lead wire 41 or an external lead wire 42 by plasma arc. The welding of the metal foil 3 to the internal lead wire 41 is performed by placing the metal foil 3 on the earth electrode of a plasma arc welding machine, arranging the internal lead wire 41 on the metal foil 3, and generating a plasma arc discharge from a plasma touch toward a welding scheduled part of the internal lead wire 41 in plasma gas atmosphere. The connection of the weld part can be ensured to improve the strength, and the disconnection or peeling from the weld part can be prevented in the sealing with a quartz glass-made bulb 1 or the lighting of a vessel L1.

摘要： PROBLEM TO BE SOLVED: To maintain a temperature at an end of a conductive foil to a specified value or less and provide superior service life characteristics by forming a film with its thermal conductivity and high radiation rate at a sealing part. SOLUTION: When thermal conductivity is (a) (cal/cm sec deg.C), and a radiation rate is (b) on surfaces of sealing parts 2 and 3 in which a molybdenum foils (conductive foils) 4 and 5 are embedded, aluminum nitrate films 15 and 16 composed of a material that meets a condition of a b>0.1 (cal/cm sec deg.C) are formed. In this case, higher thermal conductivity of a film material absorbs heats of sealing parts 2 and 3 a higher radiation rate of the film material discharge the absorbed heats to the outside; therefore, a temperature at an end on a side further than the bulb center of the sealing parts 2 and 3 of the foils 4 and 5 being lit is lowered. By forming the films 15 and 16 with their thermal conductivity and radiation rate at the sealing parts 2 and 3, the end part temperature of the sealing parts while a lamp is lit is maintained to 350 deg.C or less despise the sealing parts 2 and 3 easily manufactured, and inexpensive, superior service life characteristics are provided.

摘要： PROBLEM TO BE SOLVED: To shorten the protruding length of a glass bulb upper part and ensure an air passage by extending one conductor, and engagingly locking its tip to the neck part on the top end of the glass bulb through a bead. SOLUTION: An automobile bulb 1 is formed of a glass bulb 2 the opening of which is sealed by a base 3, and a traveling beam filament 4, a conductor 5 for the same, a passing beam filament 6, a conductor 7 for the same, a shield 8, and a common conductor 9 collectively sealed within the glass bulb 2. A halogen gas is also sealed therein. The tip of the common conductor 9 (upper end) is engagingly locked by the glass bulb 2 through a bead 10. The common conductor 9 has a locking protruding part on the upper part, and a linear part formed above it, and the bead 10 is fitted to the linear part, and the outermost circumferential part of the bead 10 is brought into contact with the inner surface of the neck part of the glass bulb 2. Since the height dimension of the bead 10 is small, the protruding height of the neck part is minimized. Thus, a small- sized bulb can be easily manufactured.

摘要： PROBLEM TO BE SOLVED: To improve the airtightness of a squeeze seal section by forming chromium layers on the surfaces of metal foils buried on the seal section. SOLUTION: The right end sections of inner lead wires 19, 20 are fixed to the left end sections of a pair of molybdenum foils 21, 22 buried on a squeeze seal section 13 and sealed airtightly as shown in the figure, and a pair of tungsten outer lead wires 23, 24 are connected to the right end sections of the molybdenum foils 21, 22. The outer faces of the connection end sections of the molybdenum foils 21, 22 fixing and electrically connecting a pair of inner lead wires 19, 20 and a pair of outer lead wires 23, 24 are coated with chromium layers 27 respectively. The chromium layers 27 have required flat areas on the molybdenum foils 21, 22, and the lead wires 19, 20, 23, 24 can be easily mounted. The chromium layers Z7 are prevented from being fused and evaporated to generate bubbles by heating when the squeeze seal section 13 is formed, and the airtightness of the squeeze seal section 13 can be improved.

摘要： PROBLEM TO BE SOLVED: To provide a miniaturized lamp or a device fitted with the lamp by making the interval between lead wires narrower in width on the inner side than on the outer side. SOLUTION: A bead mount 2 is sealed at the end section of a bulb 1 to airtightly bury and fix lead wires 4, and a filament 5 is suspended at the tip section on the inner side. The interval between the lead wires 4 at the portion extended from a bead 3 is made narrower in width on the inner sides 4A than on the outer sides 4B outside the bulb 1, and glass cover sections 7 are formed at the portions where the inner sides 4A of the lead wires 4 are extended. The glass bulb 1 is exhausted and kept at the vacuum state by a seal section 8, or an inert gas such as Ar is filled. The glass cover sections 7 are formed on the surfaces of the inner sides 4A to extend the creeping distance, and the pressure resistance of the lead wires 4 can be increased.

摘要： PURPOSE: To provide an incandescent lamp which is prevented from discharge or short-circuit between a pair of internal leads supported by a bridge glass and a lighting device using it. CONSTITUTION: A filament 8 is stored in a bulb 2 with one end sealed, one ends of a pair of internal leads 10, 11 with the other ends connected to the filament 8 are guided to a sealing portion 3 and a bridge glass 9 is provided between the sealing portion 3 and the filament, 8. A pair of internal leads 10, 11 mutually separated are supported at both ends of the bridge glass, and an anchor 12 is supported at the middle of the bridge glass 9 to support the middle of the filament 8. In this way, since the anchor is supported at the middle of the bridge glass and a pair of internal leads are supported at both ends of the bridge glass, these internal leads are mutually separated to prevent discharge or short-circuit therebetween.

摘要： PURPOSE: To provide a light source in which internal stress does not generate in a sealing part even if shock or vibration is applied and a bulb is thermally expanded, and damage such as breakage is prevented, and provide a manuscript reading-use irradiation device using this light source device, and a heating device. CONSTITUTION: In a light source in which a fixing fixture 2 is connected to an external lead-in wire 16a introduced from the end of a tubular bulb 10, and the fixing fixture 2 is fixed to a supporting member 4 by a linkage hole 21, a bent part 22 capable of elastically deforming is formed on the way of the fixing fixture 2. Even when shock or vibration is applied to the tubular light source, it is thermally expanded, the bent part of the fixing fixture is elastically deformed to absorb the shock or vibration, and allows the elongation of the bulb. Thereby, internal stress does not generate in a sealing part, and damage such as breakage is prevented.
