PURPOSE: A light illuminating apparatus including an ultrasound wave generator is provided to generate ultrasound wave between 15 and 25 KHz bands and discharge the ultrasound wave to an indoor space through an ultrasound wave discharging hole. CONSTITUTION: A housing(14) includes a space part(12) with a pre-set depth. The housing is mounted to a wall or a ceiling using a separating combining unit. A lamp(18) is inserted into a socket installed in the housing. A cover(20) is combined with the opening part of the housing. An ultrasound wave generator(22) generates ultrasound wave between 15 and 25KHz bands. An ultrasound wave discharging hole(24) is formed at the upper side of the housing. |
