摘要： A fluorescent lamp which comprises a vacuum-tight envelope provided with electrodes between which discharge takes place during the operation of said fluorescent lamp. The envelope is coated on the inside with a phosphor composition layer comprising: a first light-emitting material having an emission spectrum with a peak in the wavelength range between 465 and 490 nm, or preferably between 480 and 490 nm, and a half width ranging from 30 to 120 nm, or preferably from 70 to 100 nm; a second light-emitting material having an emission spectrum with a peak in the wavelength range between 550 and 580 nm, or preferably between 560 and 570 nm, and a smaller half width than 110 nm; a third light-emitting material having an emission spectrum with a peak in the wavelength range between 600 and 620 nm, or preferably between 610 and 620 nm; and a fourth light-emitting material having an emission spectrum with a peak in the wavelength range between 480 and 500 nm, or preferably between 480 and 490 nm, thereby ensuring high luminous flux and satisfactory color rendering.
