    Abstract: A discharge lamp of the present invention radiates visible light having the following lights combined: light having an emission peak in 400 to 490 nm wavelength range in a blue spectral region; light having an emission peak in a 500 to 550 nm wavelength range in a green spectral region; and light having with an emission peak in 600 to 670 nm wavelength range in a red spectral region. The color point of the radiated light lies within a region common to the following regions: a region bounded by an ellipse with a color point (u, v) = (0.224, 0.330) as a center thereof, a major axis of 0.056, a minor axis of 0.024, and an angle from the u axis of 20 degrees in the CIE 1960 UCS diagram; a region bounded by an ellipse with a color point (u, v) = (0.224, 0.330) as a center thereof, a major axis of 0.078, a minor axis of 0.014, and an angle from the u axis of 30 degrees in the CIE 1960 UCS diagram; a region bounded by an ellipse with a color point (u, v) = (0.235, 0.335) as a center thereof, a major axis of 0.060, a minor axis of 0.030, and an angle from the u axis of 30 degrees in the CIE 1960 UCS diagram; a region bounded by an ellipse with a color point (u, v) = (0.225, 0.330) as a center thereof, a major axis of 0.060, a minor axis of 0.018, and an angle from the u axis of 20 degrees in the CIE 1960 UCS diagram; and a region on a side of color temperature lower than an isotemperature line of a correlated color temperature of 3500K.

    Abstract: A low pressure mercury vapor fluorescent discharge lamp, having a color rendering value as high as 97 is obtainable by applying on the inner wall of the lamp a layer of a phosphor mixture comprising a basic magnesium arsenate phosphor containing 0.02 -0.2 gram-atom of manganese per 6 mols of magnesium oxide, magnesium tungstate, tin-activated strontium magnesium orthophosphate and antimony-and-manganese-activated calcium halophosphate.

    Abstract: PURPOSE: To provide a fluorescent lamp capable of suppressing change to black of a dark brown spot generating on the inside of a glass tube and change to yellow of a transparent conductive film, lengthening life, and making starting of the lamp easy even at low temperature. CONSTITUTION: A transparent film 2 is formed on the inside surface of a glass tube 1 having electrodes 7 arranged at each side and into which a rare gas is sealed together with mercury, a protecting film 3 made of a metal oxide is formed on the transparent conductive film 2, and a fluorescent material film 4 is formed op the protecting film 3. The fluorescent film 4 and the protecting film 3 in the vicinity of each electrode 2, or within the range of 120mm apart from each end of the glass tube 1 are removed to form each opening part 5 and each conductor 6 is formed in the each opening part 5.

    Abstract: PURPOSE:To form a scattering-protective film on a circular glass tube easily by immersing a lower side part of a circular glass tube in a tank of painting liquid where painting liquid including high polymeric resin is contained while it is rotated in an arc direction to apply the painting liquid to the whole outer surface of the glass tube. CONSTITUTION:A lower side part of a circular glass tube 3 having closed parts at both ends is immersed in a tank 11 of painting liquid where painting liquid 12 including high polymeric resin is contained while the glass tube 3 is rotated in an arc direction to apply the painting liquid 12 to the whole outer surface of the glass tube 3 for forming a layer of the painted liquid, and this layer of painted liquid is heated and dried. The thickness of the painted liquid is thus equalized. A scattering-protective film comprising high polymeric resin can thus be formed on the outer surface of the glass tube 3 easily.

    Abstract: PURPOSE:To enhance both the luminous flux of a scatter-proofing yellow fluorescent lamp and the rate of maintenance of the luminous flux and also enable cost reduction of the lamp by employing a single coating method on the inner surface of the glass tube of the fluorescent lamp, and forming a yellow resin film of a yellow pigment and a macromolecular resin on the outer surface of the tube so as to absorb light of low wavelength. CONSTITUTION:A fluorescent lamp glass tube having a film of a yellow light- emitting body having a peak of light emission between 560 and 590nm is immersed at its outer surface in a mixed liquid of a polyurethane water dispersed body and a water dispersed liquid of a yellow organic pigment which absorbes light of 500nm and less and is then dried by hot air to form a yellow film on the outer surface. A high luminous flux value is thereby obtained and the rate of maintenance of the luminous flux is also enhanced. Even if the glass tube is broken as a result of a drop test, the film would not be broken and pieces of broken glass are attached to the film and prevented from scattering. Work is thus made easy and simple and the manufacturing cost of the fluorescent lamp can be reduced.
