PURPOSE: A light degradation acceleration system is provided to evaluate the influence of lights with respect to a color change by measuring a discoloration extent of a measurement specimen according to wavelengths of radiation energy. CONSTITUTION: A light degradation acceleration system comprises a specimen mounting unit(13), a filter unit(19), a light source, a heat radiation unit(17), and a cylindrical body(11). A measurement specimen for evaluating discoloration extent caused by radiation energy is mounted in the specimen mounting unit. The filter unit is arranged in the specimen mounting unit, thereby selectively transmitting wavelengths of lights being irradiated to the measurement specimen. The light source irradiates the lights to the measurement specimen. The heat radiation unit emits heat generated in the light source unit to the outside. The cylindrical body is spaced from the light source unit, thereby covering the light source unit and accommodating the specimen mounting unit. |
