Abstract (en)
[origin: EP2881968A1] Provided is a ceramic metal halide lamp that is favorable for illuminating fresh foods in the manner of a high-chroma, high-color-rendering, high-pressure sodium lamp. A method for producing the ceramic metal halide lamp, which has a light-emitting tube formed from a translucent ceramic in which are sealed a starting noble gas, mercury, and an additive, and a translucent outer tube that houses the light-emitting tube, contains: a wavelength region splitting step for splitting the wavelength region (380-780 nm) of visible light into the four wavelength regions of a violet-blue color system, a green color system, a yellow color system, and an orange-red color system; and an additive setting step for setting the composition and amount added of the additive in a manner so that the ratio of the integrated value of the energy strength of light from the light-emitting tube calculated for each of the four wavelength regions is 6 ± 3 : 18 ± 5 : 6 ± 3 : 70 ± 11 (where the total value is 100).
