Abstract
A ceiling mounted ventilation fan with illumination capable of suppressing conduction of noise to inside of a room is provided. In the fan, a restriction member is provided for restricting passage of air between a lighting cover and a periphery of a lighting part, the lighting cover having a reflecting surface for reflecting light from the lighting part to lead the light to the inside of the room. A gap for air intake is formed between a lower end of the lighting cover and an edge of the indoor-side opening. Thus, air introduced into the main housing through the gap is discharged into the duct by the fan unit and conduction of noises produced by the fan unit to the room inside with the noise directivity enhanced in the lighting cover can be suppressed by the restriction member, so that conduction of noise to the room inside can be suppressed.
