<p>PURPOSE: To obtain a variable color temperature light source device which can realize the lights of different color rendering properties by the same light color. CONSTITUTION: The variable color temperature light source device is composed of a low color temperature light source 1 belonging to a low color temperature area, and a high color temperature light source 2 belonging to a high color temperature area, and to the light source of the low color temperature light source, a three-wavelength area emission type fluorescent lamp 11a and a continuous spectrum high color rendering type fluorescent lamp 11b are used as at least two sorts of light source with different spectrum. To the light source of the high color temperature light source, a three-wavelength area emission type fluorescent lamp 21a and a continuous spectrum high color rendering type fluorescent lamp 21b are used as at least two sorts of light source with different spectrum, and those lamps are flashed or dimming controlled by a dimming control device 3.</p> |
