Abstract

A ventilation system comprises a ventilation fan with a lamp and a ceiling which has an installation opening. The ventilation fan with the lamp is adapted for installing to the ceiling through the installation opening. The ventilation fan comprises a housing, a fan module, and a lamp module. The housing includes a top plate and a side wall which are connected with each other to form a first opening. The first opening is aligned with the installation opening. The fan module is disposed in the housing. The lamp module is disposed out of the installation opening. The lamp module and the housing are located at opposite sides of the installation opening of the ceiling. The lamp module includes a light source, a base, at least one optical component, a switch and a lamp cover. The optical component and the switch are disposed at the different sides of the base.

First claim

What is claimed is:

1. A ventilation system comprising a ventilation fan with a lamp and a ceiling having an installation opening, wherein the ventilation fan with the lamp is adapted for installing to the ceiling through the installation opening, the ventilation fan comprises:
a housing including a top plate and a side wall, wherein the top plate and the side wall are connected with each other to form a first opening, and the first opening is aligned with the installation opening;
a fan module disposed in the housing;
a lamp module totally disposed below the ceiling and out of the installation opening, wherein the lamp module and the housing are located at opposite sides of the installation opening of the ceiling, respectively;
a support disposed between the ceiling and the lamp module; and
a contacting portion connecting the lamp module and the support and disposed between the lamp module and the support;
wherein the lamp module includes a light source, a base, at least one optical component, a switch and a lamp cover, wherein the light source, the base, the at least one optical component, the switch and the lamp cover are totally disposed below the ceiling and out of the installation opening, the optical component and the switch are disposed at different sides of the base, respectively,
wherein the lamp cover is disposed at one side of the optical component away from the base, and the switch is disposed on the base and towards the installation opening,
wherein the lamp module is under the contacting portion which is under the support, and the support is under the ceiling,
wherein the support and the lamp module are parallel, the contacting portion is vertical to the lamp module and the support respectively, a gap is configured between the lamp module and the support, a length of the contacting portion is equal to a height of the gap.

2. The ventilation system as recited in claim 1 , wherein the light source comprises at least one light-emitting diode.

3. The ventilation system as recited in claim 1 , wherein the gap serves as an air inlet of the ventilation fan.

4. The ventilation system as recited in claim 3 , further comprising a second opening disposed at the housing and serving as an air outlet of the ventilation fan.

5. The ventilation system as recited in claim 1 , wherein the switch comprises a water-proof structure.

6. The ventilation system as recited in claim 5 , wherein the switch is a multi-stage switch.

7. The ventilation system as recited in claim 6 , wherein the switch is disposed to control light color, light color temperature or brightness of the lamp module.

8. The ventilation system as recited in claim 1 , wherein the lamp cover is attached to the ceiling.
