Abstract

A lighting ventilation fan is disclosure and includes a housing, a grille support, a fan module, a lighting base, plural connecting columns, a lighting module and a function module. The grille support, the lighting base and the lighting module form a grille structure mounted under a ceiling. The fan module disposed within the housing forms an airflow flowing. The lighting base and the grille support are connected through the plural connecting columns and spaced apart from each other. An inlet radially formed between the lighting base and the grille support is in communication with the outlet through the grille opening. The lighting base includes a holder having a holding opening axially downward and faced away from the housing. The lighting module is disposed in the lighting base and has a light-emitting surface emitting light axially and radially. The function module is disposed within the holder through the holding opening.

First claim

What is claimed is:

1 . A lighting ventilation fan, comprising:
a housing having a bottom spatially corresponding to an opening of a ceiling and comprising:
a fan module disposed with in the housing; and
a grille structure comprising:
a grille support mounted under the ceiling and comprising a grille opening spatially corresponding to the opening of the ceiling;
a lighting base comprising a holder, wherein the holder comprises a holding opening faced away from the housing;
a plurality of connecting columns connected between the grille support and the lighting base, so that an inlet facing a radial direction is formed between the grille support and the lighting base;
a lighting module disposed on the lighting base and comprising a LED light-emitting element and a light-emitting surface facing the axial direction and the radial direction;
an elastic element extended from the grille support or the lighting base, and engaged with the housing; and
a function module disposed within the holder through the holding opening.

2 . The lighting ventilation fan according to claim 1 , wherein the function module is one selected from the group consisting of a Bluetooth-speaker module, a night-light module, a humidity-sensor module, a germicidal-lamp module and a human-body-detector module.

3 . The lighting ventilation fan according to claim 1 , further comprising a cover spatially corresponding to the holder and covering the holding opening and the function module disposed within the holder.

4 . The lighting ventilation fan according to claim 3 , wherein the cover comprises a plurality of grille apertures, and the function module disposed within the holder is in communication with an exterior of the cover through the plurality of grille apertures.

5 . The lighting ventilation fan according to claim 3 , wherein the function module is attached adjacent to the cover to form a function region, wherein the function region, the cover and the light-emitting surface are arranged concentrically along the radial direction from inner to outer, wherein an outer diameter of the light-emitting surface is greater than an outer diameter of the cover, and the outer diameter of the cover is greater than an outer diameter of the function region.

6 . The light ventilation fan according to claim 5 , wherein the LED light-emitting element of the lighting module is disposed adjacent to an outer periphery of the holder, wherein the function region and the LED light-emitting element are located on an identical axial projection plane.

7 . The lighting ventilation fan according to claim 1 , wherein the light-emitting surface comprises an axial light-emitting surface and a lateral light-emitting surface, the axial light-emitting surface faces the axial direction, the lateral light-emitting surface faces the radial direction, and the axial light-emitting surface and the lateral light-emitting surface are in connection with each other and integrally formed into one piece.

8 . The lighting ventilation fan according to claim 1 , wherein an outer diameter of the light-emitting surface is greater than or equal to an outer diameter of the lighting base and an outer diameter of the grille support.

9 . The lighting ventilation fan according to claim 1 , wherein the LED light-emitting element of the lighting module is located at an inner periphery of the light-emitting surface, and the lighting module comprises:
a light guide plate having an inner periphery connected to the LED light-emitting element and extended outwardly along the radial direction; and a reflective plate connected to the LED light-emitting element and the light guide plate to form a reflective surface axially downward.

10 . The lighting ventilation fan according to claim 9 , wherein the lighting module further comprises a light board, and the light guide plate and the reflective plate are fixed between the light board and the lighting base, wherein the light board has a first side attached to the light guide plate and a second side opposite to the first side and configured to form the light-emitting surface.

11 . The lighting ventilation fan according to claim 1 , wherein the grille support and the lighting base have a spaced height formed therebetween, the plurality of connecting columns and an outer periphery of the lighting base have an interval distance, and the interval distance is greater than the spaced height.

12 . The lighting ventilation fan according to claim 1 , wherein the holder is a GU24 base socket.

13 . The lighting ventilation fan according to claim 1 , further comprising a first power module, a second power module and a third power module, wherein the first power module is disposed in the housing and electrically connected to the fan module, the second power module is disposed on the lighting base and electrically connected to the lighting module, and the third power module is included in the function module and configured to be received within the holder.

14 . The lighting ventilation fan according to claim 1 , wherein the grille support comprises a first curve portion disposed around a periphery of the grille opening.

15 . The lighting ventilation fan according to claim 14 , wherein the fan module further comprises a fan-module opening in communication with the grille opening along the axial direction.

16 . The lighting ventilation fan according to claim 15 , wherein a second curve portion is formed on a periphery of the fan-module opening.

17 . The lighting ventilation fan according to claim 15 , wherein the grille opening is greater than the fan-module opening.

18 . The lighting ventilation fan according to claim 1 , wherein the fan module comprises a motor and an impeller disposed along the axial direction and configured to form a centrifugal fan.
