Abstract

PURPOSE:To provide a fluorescent lamp convenient for meticulous examination by approximating the spectral distribution of the light irradiated from the fluorescent lamp to the reference light of flat relative energy for each wavelength. CONSTITUTION:The fluorescent lamp is mixed with plural phosphors on the inside surface of its glass bulb. The color temp. K of this fluorescent lamp is set at 5,200<=K<=5,800, and the deviation of the full radiator in a CIE (JIS) chromaticity diagram with respect to color locus regulated within a + or -0.000>=uv>=-0.01 when the scale of the CIE uv chromaticity diagram is indicated as a unit. The spectral distribution of the light irradiated from the fluorescent lamp is approximated to the reference light (illuminating light E) of flat relative energy for each wavelength.
