摘要： PURPOSE:To increase the saturation of the material irradiated by coating a neomdyium oxide film on the inner surface of a glass tube. CONSTITUTION:A neomdyium oxide or the one mixed with yttrium oxide and baked, is coated on the inner surface of a glass tube, and a phosphor (Ca10(PO4)6 FCl:Sb, Mn) 2 such as a calcium halophosphate phosphor is coated thereon. The light near 568-589nm of this lamp is absorbed by the neomdyium oxide, and the saturation is increased thereby.

摘要： PURPOSE:To reduce emission spectra near a specified wavelength and form a fluorescent lamp having an increased saturation of an irradiated body by containing oxidized neodium in a glass tube. CONSTITUTION:A calcium halo phosphor 2 is formed on the inner surface of a straight glass tube 1 having, for example a full length of 580mm and an outer diameter of 32.5mm, which consists of a soda glass with a determined thickness containing 1.4mg/cm of oxidized neodium, and, in this case, 25mg of argon 2.5Torr and Hg are sealed in the inner part thereof. When such a lamp is lighted at rated 20W, the color temperature in this case shows 4792K, while the color temperature of a fluorescent lamp using a glass containing no oxidized neodium shows 4289K. The fluorescent lamp in this case is reduced in emission strength as the lights near 568-589nm are absorbed by the oxidized neodium. Hence, the saturation of an irradiated body can be increased.

摘要： PURPOSE:To realize reduction in light energy cost accounting for a great part of production cost by providing a fluorescent substance layer consisting of three kinds of rare earth element-activated fluorescent substances having light emission peaks wavelength within specific ranges and a fluorescent substance having the light emission wavelength within a specific range on the inner surface of a glass tube. CONSTITUTION:A fluorescent substance suspension is prepared by respectively using a bivalent europium-activated barium magnesium aluminate as a blue emitting fluorescent substance emitting light at 440-470nm wavelength, terbium- activated cerium magnesium aluminate as a green emitting fluorescent substance emitting light at 540-560nm wavelength, trivalent europium-activated yttrium oxide as a red emitting fluorescent substance emitting light at 610-630nm wavelength and an iron-activated lithium aluminate as a fluorescent substance having the emission peak at 700-800nm wavelength. The resultant suspension is used and applied onto the inner surface of a glass tube to prepare a straight 40-W fluorescent lamp by a conventional method.

摘要： PURPOSE:To prevent any luminance nonuniformity of the surface of an illuminated signboard by coating the entire inner surface of a glass tube with a phosphor film after a semicylindrical inner surface of the glass tube is coated with a reflection film, and restricting the rati of the luminous intensity of the non-reflection film side to that of the reflection film side to a given value. CONSTITUTION:After an apatite is applied to the inner wall of a glass tube 1 and is dried, a part of the apatite film which covers a semicylindrical inner surface of the tube 1 is removed, thereby forming a reflection film 2. After that, the inner wall of the tube 1, and the film 2 are coated with a daylight colored phosphor before the phosphor is dried, thereby forming a phosphor film 3. the thicknesses of the films 2 and 3 are adjusted so that the ratio of the luminous intensity of the non-reflection film side to that of the reflection film side becomes 1.4-4.0. Then, a fluorescent lamp 4 is made by a usual method. An illuminated signboard is constituted by placing a plural number of fluorescent lamps 4 in a box 6, to which a diffusion board 5 is fixed. As a result, the luminance nonuniformity of the signboard surface can be almost completely suppressed.

摘要： PURPOSE:To prevent any luminance nonuniformity of the surface of an illuminated signboard by forming a reflection film, which has a slit extending in the axial direction of a glass tube, on the inner wall of the glass tube, and forming a phosphor film over the reflection film. CONSTITUTION:A reflection film 2 is formed on the inner wall of a glass tube 1 by applying an apatite to the inner wall and drying the apatite. A slit 3 is provided at the center of the film 2 over the entire length of the tube 1 in the axial direction of the tube 1. After that, the inner wall of the tube 1, and the film 2 are coated with a daylight colored phosphor, and the phosphor is dried, thereby forming a phosphor film 4. Then, a fluorescent lamp 5 is made by a usual method. An illuminated signboard is constituted by placing a plural number of fluorescent lamps 5 in a box 8, to which a diffusion board 6 and a reflection film 7 are fixed. As a result, the luminance nonuniformity of the signboard surface can be almost completely suppressed.
