FLUORESCENT LAMP AND METAL HALIDE LAMP

摘要

A fluorescent lamp or metal halide lamp which ensures color reproducibility to enable categorical identification of surfaces colors of at least red, green, blue, yellow and white of an illumination object. The fluorescent lamp or metal halide lamp generates a light having a high luminous efficacy in scotopic vision and mesopic vision or in a large visual field, or generates a light having a white color which has less difference in light color in the case where the fluorescent lamp or metal halide lamp is used together with a high color temperature light source, or generates a light equivalent to an incandescent lamp color which has less difference in light color in the case where the fluorescent lamp or metal halide lamp is used together with a low color temperature light source.
