    摘要: An object of the invention is to provide a blue-green light-emitting phosphor having excellent high-temperature property and excellent light-emitting properties such as brightness and half width. The phosphor is constituted of a plurality of alkaline earth metal elements including a barium element, phosphoric acid and a halogen element, and Eu as an activator, in which the molar ratio of the barium element to the total content of the alkaline earth metal elements is larger than 60% and smaller than 95%, and upon irradiation with a near-ultraviolet ray, the blue-green light-emitting phosphor is excited to thereby emit blue-green visible light.

    摘要: Provided is a white light source system that reproduces the light-emission properties of sunlight having temperature colors and light-emission spectrum shapes that change over time, said white light source system being used for office and domestic illumination. As a result of the present invention, a white light source system is provided that includes a plurality of white light sources. A relationship formula is fulfilled whereby the absolute value is no more than 0.15 for the difference between P (λ) × V (λ) / P (λmax1) × V (λmax1) and (B (λ) × V (λ)) / B (λmax2) ×V (λmax2), when the light-emission spectrum for each white light source is P (λ), the light-emission spectrum for black body radiation indicating the same color temperature as each white light source is B (λ), the spectrum for spectral luminous efficiency is V (λ), the maximum wavelength for P (λ) × V (λ) is λmax1, and the maximum wavelength for B (λ) × V (λ) is λmax2. The white light source system is characterized by the light-emission properties of the white light emitted from the system continuously changing over time, as a result of changing the mixing ratio for light from a plurality of white light sources.

    摘要: Disclosed is a halophosphate phosphor activated with divalent europium, which is represented by the formula:
    wherein M represents three alkaline earth metals consisting of barium, calcium and magnesium; X represents at least one of fluorine, chlorine and bromine; RE represents at least one of rare earth elements selected from the group consisting of ytterbium, neodymium, samarium, dysprosium, holmium and thulium; and a and b each represent a positive number of less than 5.
    Disclosed is also a fluorescent lamp which comprises a glass tube and a mixture of a halophosphate phosphor activated with divalent europium represented by the above formula and a strontium-magnesium orthophosphate phosphor activated with tin represented by the formula: (Sr,Mg) 3 (P0 4 ) 2 :Sn, the mixture being cated on inside wall of the glass tube.
    The halophosphate phosphor of this invention can decrease to a greater extent the afterglow as compared with those known in the prior art, without loss of the luminescence intensity. The fluorescent lamp of this invention has large initial luminous flux and luminous flux-maintaining efficient, color rendering at 4,200 to 5,600 K classified into the EDL type, afterglow time being shortened to the level at which any problem does not arise in practical use.
