Luminaire of variable color temperature for obtaining a blend color light of a desired color temperature from different emission-color light sources

摘要

A luminaire of variable color temperature is arranged for emitting blended color light from luminaire section, with color temperature control signals so transmitted from control section to luminaire-lighting section as to substantially equalize respective differences in reciprocal color temperatures of respective two adjacent stages of the color temperature control signals, to thereby render blended state of emission colors to be variable and a dimming of the blended color light to be realized with the color temperature gradually varied in smooth manner.
