Abstract

A ventilation system comprising a ventilation fan with a lamp and a ceiling having an installing opening. The ventilation fan includes a housing having a first opening and a second opening, a fan module and a lamp module. The lamp module is fixed to the first opening by a plurality of elastic elements passing through the housing. Wherein the lamp module comprises a LED light source, a base, at least one optical component and a lamp cover. The lamp cover is disposed at one side of the optical component away from the base. The light output direction of a LED light source of the lamp module is different from the light output direction of the lamp module. Wherein the lamp module contacts the ceiling by a support to form a gap configured between the lamp module and the support, and the gap serves as the air inlet.

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 installation in the installation opening of the ceiling, the ventilation fan comprising:
a housing including a first opening and a second opening, wherein the first opening is configured to be aligned with the installation opening; a fan module disposed in the housing; and a lamp module fixed to the first opening by a plurality of elastic elements passing through the housing, and the lamp module and the housing are located at opposite sides of the installation opening of the ceiling; wherein the lamp module comprises a LED light source, a base, at least one optical component and a lamp cover, the optical component is disposed on the base, the lamp cover is disposed at one side of the optical component away from the base, and the light output direction of the LED light source of the lamp module is different from the light output direction of the lamp module; and wherein the lamp module contacts the ceiling by a support to form a gap configured between the lamp module and the support, and the gap serves as the air inlet.

2 . The ventilation system as recited in claim 1 , wherein the light output direction of the LED light source of the lamp module is perpendicular to the light output direction of the lamp module.

3 . The ventilation system as recited in claim 1 , wherein the optical component is a light diffuser, and the light diffuser receives the light emitted from the LED light source of the lamp module.

4 . The ventilation system as recited in claim 1 , wherein the lamp module and the support are connected by a contact portion so that the length of the gap is defined by the contact portion.

5 . The ventilation system as recited in claim 1 , wherein the ventilation fan further comprising a filter disposed in the support.

6 . The ventilation system as recited in claim 1 , wherein the second opening is aligned with the installation opening, wherein the ventilation fan is configured such that, during disassembling, the lamp module is suspended in the air by the elastic elements engaged to the housing so as to prevent the lamp module from falling down directly.

7 . 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 installation in the installation opening of the ceiling, the ventilation fan comprising:
a housing including a top plate, a side wall and two extension portions, wherein the top plate and the side wall are connected with each other to form a first opening, the first opening is aligned with the installation opening, the extension portions are disposed on the side wall inside the housing, and a slot is formed on each of the extension portions; a fan module disposed in the housing; and a lamp module fixed to the first opening by a plurality of elastic elements passing through the housing, and the lamp module and the housing are located at opposite sides of the installation opening of the ceiling; wherein the lamp module comprises a LED light source, a base, at least one optical component, and a lamp cover, the optical component is disposed on the base, the lamp cover is disposed at one side of the optical component away from the base, and the light output direction of the LED light source of the lamp module is not equal to the light output direction of the lamp module; and wherein the lamp module contacts the ceiling by a support to form a gap configured between the lamp module and the support, and the gap serves as the air inlet.

8 . The ventilation system as recited in claim 7 , wherein the lamp module and the support are connected by a contacting portion.

9 . The ventilation system as recited in claim 7 , wherein the ventilation fan further comprising a filter disposed in the support.

10 . The ventilation system as recited in claim 7 , wherein the fan module has a first projection plane on the top plate, the installation opening has a second projection plane on the top plate, and the first projection plane and the second projection plane are substantially not overlapped.

11 . The ventilation system as recited in claim 7 , wherein the fan module has a first projection plane on the top plate, the installation opening has a second projection plane on the top plate, and the size of the first projection plane is smaller than that of the second projection plane.

12 . The ventilation system as recited in claim 7 , wherein the optical component is a light diffuser and the LED light source is disposed at the side of the light diffuser.

13 . The ventilation system as recited in claim 7 , wherein the elastic element has two hook structures, a V-shaped structure and a ring structure, the hook structures are disposed at two ends of the V-shaped structure, the ring structure is configured at a bottom of the V-shaped structure and between the two hook structures, the ring structure is partially connected to the base of the lamp module, and the lamp module is connected to the housing by the hook structures penetrating through the slots, respectively.
