Abstract: A ceiling mounted airway device with illumination, which includes a main housing, a lamp and a lamp fixing part to detachably fix the lamp to an inner wall of the main housing. The main housing includes: a first opening for exhausting air out of the main housing; and a second opening for sucking air into the main housing. The lamp includes: an electrically conductive contact terminal located at an upper end of the lamp and electrically powered via the lamp fixing part; and a flange protruding from a surface of the lamp and located below the electrically conductive contact terminal. The device further includes a shield for supporting the flange which is substantially in form of a cylinder and surrounds the electrically conductive contact terminal and the lamp fixing part.
