Abstract
A fluorescent lamp includes a lamp body, a fluorescent layer and a discharge electrode. The lamp body has a discharge space in which ultraviolet light is generated. The fluorescent layer is formed on an inner surface of the lamp body to change the ultraviolet light into visible light. The discharge electrode is on an end portion of the lamp body to apply a voltage to the discharge space. A ratio of intensities of the visible light at wavelengths of about 545 nm and about 516 nm is about 1.32:1 to about 1.71:1. Therefore, color reproducibility and luminance may be improved.
