PURPOSE:To provide an illuminator which produces life space with an illumination light having natural fluctuation through liquid by covering a light source installed at a ceiling, and causing movement in the liquid accommodated inside the cover. CONSTITUTION:An illumination cover 2 by an acylic board or the like is fixed to a structural member such as the beam 3 or the like at a ceiling face by means of a bolt and a nut 4, and also a light source 1 such as a fluorescent lamp is attached to the ceiling face 8, and a transparent inner cover 6 is provided between the light source 1 and the transparent cover 2, and liquid 7 such as water or the like is accommodated in the space between both covers 2 and 6. Indoor space is produced with an illumination light having natural fluctuation through this liquid 7 by lighting the light source 1 and also, vibrating it with the vibration plate 5b inside the liquid by means of a vibrator 5a thereby generating fluctuation in the liquid 7. |
