[0023] In the description of this invention, terms such as "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] Reference Figures 1 to 6 As shown, this embodiment provides a skylight with an exhaust fan, including a skylight body 10 and an exhaust fan 20, wherein the exhaust fan 20 is fixedly mounted on the back of the skylight body 10 away from its light-emitting surface; as shown Figure 3 As shown, the light-emitting surface of the blue sky lamp body 10 faces downward, while the exhaust fan 20 is fixed to the upper end of the blue sky lamp body 10. In this way, when the blue sky lamp is installed on the ceiling, the exhaust fan can be hidden and will not increase the floor space.

[0027] The blue sky lamp body 10 has a heat dissipation cavity 102 and an air inlet 101 and an air outlet 103 communicating with the heat dissipation cavity 102. The heat dissipation cavity 102 forms a heat conduction with the blue sky lamp light source 14 of the blue sky lamp body 10, that is, the heat generated by the blue sky lamp light source 14 of the blue sky lamp body 10 can be conducted into the heat dissipation cavity 102. The air inlet 101 is an air inlet gap formed on the outer periphery of the blue sky lamp body 10, and the air outlet 103 is formed on the back of the blue sky lamp body 10 and communicates with the air inlet end 21 of the exhaust fan 20.

[0028] The heat generated by the blue sky lamp body 10 during operation is conducted to the heat dissipation cavity 102. When heat dissipation is needed, the exhaust fan 20 is turned on. Under the action of the exhaust fan 20, external air flows from the outer periphery of the blue sky lamp body 10 into the heat dissipation cavity 102, and then flows into the exhaust fan 20 from the air outlet 103. During this process, the airflow carries away the heat in the heat dissipation cavity 102, thus dissipating heat from the blue sky lamp body 10. Furthermore, the air inlet 101 is an air inlet gap formed on the outer periphery of the blue sky lamp body 10, and the airflow is concentrated from the outer periphery of the blue sky lamp body 10 into the inner periphery. The airflow has a large circulation range, which can effectively enhance the heat dissipation effect.

[0029] Furthermore, in this embodiment, the blue sky lamp body 10 includes a fixing plate 13, a cover plate 12, a housing 11, and a blue sky lamp light source 14. A central window 111 is provided in the middle of the housing 11. The blue sky lamp light source 14 is an LED light source capable of emitting blue sky light, as is currently available in the art. The blue sky lamp light source 14 is mounted inside the housing 10, and the light is emitted through the central window 111. The cover plate 12 is fixedly fitted to the back of the housing 11. The fixing plate 13 is spaced apart from the cover plate 12 and fixed to the cover plate 12. The peripheral openings of the fixing plate 13 and the cover plate 12 spaced apart are the air inlet gaps, i.e., air inlets 101; that is, the entire outer circumference of the blue sky lamp body 10 has air inlet gaps. The cavity between the fixing plate 13 and the cover plate 12 is the heat dissipation cavity 102. An opening is provided in the middle of the fixing plate 13 to form the air outlet 103. The exhaust fan 20 is fixedly mounted on the fixing plate 13. Preferably, the cover plate 12 and the outer shell 11 are made of thermally conductive materials (such as metal materials) with good thermal conductivity, which can dissipate heat in a timely manner. The cover plate 12 serves as one side wall of the heat dissipation cavity 102. The heat generated by the light source 14 is conducted through the outer shell 11 to the cover plate 12, and then from the cover plate 12 to the heat dissipation cavity 102, where it is carried away by the airflow flowing through the heat dissipation cavity 102, thus achieving heat dissipation.

[0030] Furthermore, the cover plate 12 is provided with a plurality of connecting protrusions 121 facing the back, and the fixing plate 13 is fixed on the plurality of connecting protrusions 121 of the cover plate 12 and is spaced apart from the cover plate 12; the specific fixing method can be to use bolt fasteners for locking, or to use a snap-fit ​​structure for fixing.

[0031] Furthermore, the blue sky lamp body 10 also includes a back plate 151, a light guide plate 152, a diffuser plate 153, and a front panel 154. The back plate 151, light guide plate 152, diffuser plate 153, and front panel 154 are sequentially stacked and assembled in the central window 111 of the outer shell 11 from the back to the light-emitting surface (i.e., from top to bottom). The blue sky lamp light source 14 is disposed on the inner side wall of the central window 111 and corresponds to the peripheral side of the light guide plate 152. The light emitted by the blue sky lamp light source 14 directly passes through the peripheral side of the light guide plate 152 and illuminates the light guide plate 152. The light then passes through the light guide plate 152 and is emitted to the diffuser plate 153, where it is evenly diffused before being emitted downwards from the front panel 154. The back plate 151 serves to shield and reflect light, preventing light from shooting upwards.

[0032] Meanwhile, in this embodiment, the blue sky lamp body 10 also includes a white light source 16 and an annular light-transmitting cover 17. The outer shell 11 also forms an annular window 112 around the central window 111, and the white light source 16 is mounted inside the annular window 112. The annular light-transmitting cover 17 is mounted on the annular window 112 of the outer shell 11 and is tilted inwards. The addition of the peripheral white light source 16 serves as supplementary lighting to increase illumination brightness. Specifically, the height of the annular light-transmitting cover 17 is lower than that of the central window 111, so that the white light emitted by the white light source 16 does not affect the light emitted by the blue sky lamp source 14.

[0033] The white light source 16 is also mounted on the housing 11, and the heat it generates can be conducted to the cover plate 12 through the housing 11, thereby achieving effective heat dissipation.

[0034] Of course, in other embodiments, the structure of the white light source 16 may not be used.

[0035] Specifically, the exhaust fan 20 adopts the structure of existing technology, as long as it can introduce airflow from the outer periphery of the blue sky lamp body 10 into the heat dissipation cavity 102 and then output it from the heat dissipation cavity 102.

[0036] Specifically, when the blue sky lamp with exhaust fan provided in this embodiment is used in a relatively enclosed indoor space (such as a bathroom), the exhaust end 22 of the exhaust fan 20 is connected to an exhaust pipe, which can be used to exhaust indoor air to the outside.

[0037] The blue sky lamp with exhaust fan provided in this application integrates the exhaust fan 20 with the blue sky lamp body 10 into one unit, which has the characteristics of overall aesthetics, low cost, convenient installation and use, and easy maintenance.

[0038] Example 2

[0039] This embodiment provides a blue sky lamp with an exhaust fan. Its structure is largely the same as that disclosed in Embodiment 1, except that: in this embodiment, the fixing plate 13 is not provided. The cover plate 12 and the outer shell 11 are spaced apart, and the spaced-apart outer periphery openings of the cover plate 12 and the outer shell 11 serve as the air inlet gaps. The cavity enclosed by the cover plate 12 and the outer shell 11 is the heat dissipation cavity 102. The blue sky lamp light source 14 is located within the heat dissipation cavity 102. An opening is formed in the middle of the cover plate 12 to create the air outlet 103. The exhaust fan 20 is fixedly mounted on the cover plate 12. When the exhaust fan 20 is working, airflow flows directly from the air inlet gap between the cover plate 12 and the outer shell 11 into the heat dissipation cavity 102 where the blue sky lamp light source 14 is installed. Heat is carried away by directly blowing air onto the blue sky lamp light source 14, reducing the need for the fixing plate 13. Simultaneously, the heat emitted by the white light source 16 is conducted to the heat dissipation cavity 102 through the outer shell 11 for heat dissipation.

[0040] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
