2. Description of the Related Art Humans are always living with lights. In recent years, it has been desired to arbitrarily change the lighting of a living space according to personal preferences and living patterns in order to produce individuality through lighting from a light source rather than uniform lighting from a predetermined light source. It is rare. For example, in a cold winter, illumination with a warm, low-color temperature light source is desired, and in a hot summer, illumination with a cool, high-color temperature light source is desired. Also, at a party venue, lighting with a high color temperature light source that creates an active mood is desired, and in a living room where a family relaxes, lighting with a low color temperature light source that creates a group mood is desired.

The arithmetic and control unit 2 determines the surrounding atmosphere from the sound and the infrared signal, and controls the light color and brightness. For example, when the bass and treble are strong and the infrared output is small, it is assumed that there are two men and women around, and the color temperature of the lamp is lowered and the brightness is suppressed to produce a soft mood. When the treble is strong and the infrared output is large, it is judged as a gathering of several young women and the color temperature of the lamp is raised and brightened to create a lively mood.
