摘要： PURPOSE:To complement optical output in the missing wavelength range in a light emission spectrum of a high pressure mercury light with the light from a fluorescent substance by forming No.2 layer fluorescent substance film from lanthanum phosphate which has been activated with three-valent Ce and three- valent Tb. CONSTITUTION:A fluorescent mercury light as per invention comprises a light emitting tube 1 which emits visible rays and ultraviolet rays, an outer tube 2 surrounding this light emitting tube, and No.1 layer and No.2 layer fluorescent substance film 3, 4 which are attached to the inner surface of this outer tube. The No.1 layer fluorescent substance film is made of a fluorescent substance having light emissive peaks in the wavelength ranges 440-530nm and 600-660nm at the time of light being emitted, while the No.2 layer fluorescent substance film 4 shall consist of lanthanum phosphate activated with three-valent Ce and three-valent Tb. Thereby effect of enhancing the rendering characteristic is obtained due to complementing the optical outputs in the wavelength ranges 440-540nm and 590-700nm, which are missing in the light emission spectrum of a high pressure mercury light, with light given by fluorescent substance.

摘要： PURPOSE:To eliminate the folding/bending process for a supporting wire by using a plate shaped metal support for supporting a light emitting tube, and performing single piece molding by press processing. CONSTITUTION:Existing invention includes a metal support 14 and a base 16 fixed to the end of an outer tube 1. The metal support 14 is composed of a stay 14a and, No.1 connection part 14b, a light emitting tube pinching part 14c, and No.2 connection part 14d separating from each other and extending to the same side from the named stay 14a, wherein a notch 15 is given to the light emitting tube pinching part 14c. External drawout lead 8 on one side is straight welded to the No.1 connection part 14b. while drawin lead 7 on one side is directly welded to the No.2 connection part 14d, and the other external drawout lead 9 is welded to the other drawin lead 6. This eliminates the folding/bending process for support wire from a stem as plate-shaped metal support in single piece molded body.

摘要： PURPOSE:To improve thermal resistance and prevent discoloration and peeling of a coating film by applying, to the external surface of an outer tube, a coating film having fluorine-contained resin with thermal fluidity as a main component. CONSTITUTION:A luminous tube 2 filled with mercury and argon gas is provided in the approximate center of an outer tube bulb 1 made of soft glass such as soda glass, and the luminous tube 2 is supported by stem supporting wires 3 and 4 and electrically connected to a base 5 fixed to one end of the outer tube bulb 1. Fluorine-contained resin 6 with thermal fluidity is applied evenly to the external surface of the outer tube bulb 1. Water repellency of the coating film 6 having fluorine-contained resin with thermal fluidity as a main component and applied to the external surface of the outer tube bulb 1 suppresses a sharp drop of the outer tube bulb 1 temperature, thus preventing cracks on the outer tube 1. In addition, the coating film 6 is provided with sufficient strength against irradiation of ultraviolet rays.

摘要： PURPOSE:To reduce a noize of an instrument while suppressing oscillation of a holding line by a method, in which a luminous tube is held inside an outer tube while forming with a Monel line, the part, passing a side of the luminous tube, of the holding lines for supplying power. CONSTITUTION:A luminous tube 2 is housed in an outer tube 1 while being held by two long and short holding lines 3 and 4, whereby power is supplied to the luminous tube 2 through the holding lines 3 and 4. Thereby, the long holding line 4 passing by the luminous tube 2 is formed with a Monel line having a composition of nickel 60-70%, copper 30-40%, the tensil strength not less than 50kg/ mm. and elongation not exceeding 20%. Accordingly, the Monel line having small magnetism is used for the holding line, thus reducing the intensity of an alternating field generated by a current flowing through the holding line 4 as well as repulsive force against the alternating field generated in the luminous tube 2, while reducing a noize due to resonance of a shade or the like.

摘要： PROBLEM TO BE SOLVED: To provide an assembly method for an electrode of a discharge lamp which can accurately adjust the distance between electrodes and reduce the optical dispersion of the discharge lamp. SOLUTION: According to this method, a discharge lamp is assembled. The lamp comprises an electrode 1 consisting of a tungsten electrode head 2 having a circular shape in section that is connected to a molybdenum lead 4 having a circular shape in section through a molybdenum foil 3. In this case, a laser beam 8 is applied to the molybdenum foil 3 after metal powder or metal paste 5 is applied to the foil 3, and then the tungsten electrode head 2 or the molybdenum lead 4 are brazed with the molybdenum foil 3. Accordingly, the molybdenum foil 3 that is thin and the lead 4 or electrode head 2 which has a thickness several times or more greater than that of the molybdenum foil 3, are welded together by laser welding without generating a bend and a hole in the molybdenum foil 3. The electrode 1 can be made in this way.
