[0030] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Please refer to Figures 1 to 3. This application discloses a fan light 100, including a housing assembly 1, a fan assembly 2, a projection assembly 3, and a light source assembly 4. The housing assembly 1 includes an upper shell 11 and a lower shell 12, forming a wind cavity 10 between the upper shell 11 and the lower shell 12. The fan assembly 2 and the projection assembly 3 are both disposed within the wind cavity 10. The upper shell 11 has an air inlet 110, and the lower shell 12 has an air outlet 120. The air inlet 110, the wind cavity 10, and the air outlet 120 are interconnected, allowing external airflow to enter the wind cavity through the air inlet 110 under the action of the fan assembly 2, and then exit through the air outlet 120. In other words, by creating a wind cavity 10 inside the fan light 100, both the fan assembly 2 and the projection assembly 3 are accommodated simultaneously without interfering with each other. Thus, the fan light 100 achieves both the blowing and projection functions. Of course, in other embodiments, the projection component 3 can also be installed at other locations on the housing component 1, as long as the projection function can be achieved, and there are no restrictions here.

[0032] Furthermore, the fan light 100 of this application is a bladeless fan light, so there is no need to worry about the rotation of the fan blades affecting the projection quality of the image.

[0033] Specifically, the fan assembly 2 is housed inside the air cavity 10 and includes a motor assembly 21 and an impeller assembly 22 mounted on the lower housing 12. The motor assembly 21 is connected to the impeller assembly 22 to drive the impeller assembly 22 to rotate. When the impeller assembly 22 rotates, it drives external airflow into the air cavity 10 from the air inlet 110 and then discharges it from the air outlet 120.

[0034] The projection component 3 is configured to project patterns and direct-light illumination toward the mounting surface. Its direct-light illumination direction is the same as the illumination direction of the light source component 4, and the two are independent of each other. In other words, the projection component 3 further increases the brightness of the fan light 100. Furthermore, a night light function can be added to further expand the functionality of the fan light 100.

[0035] In this embodiment, the upper shell 11 is provided with a first mounting hole 111, and the lower shell 12 is provided with a second mounting hole 121. The first mounting hole 111, the second mounting hole 121 and the air cavity 10 are interconnected and form a receiving cavity. The projection component 3 is housed inside the receiving cavity and projects a pattern toward the mounting surface through the first mounting hole 111 and provides direct lighting through the second mounting hole 121.

[0036] The first mounting hole 111 and the second mounting hole 121 are preferably aligned with each other so that the projection component 3 can project directly upwards, ensuring the clarity of the projection. Of course, in other embodiments, the first mounting hole 111 and the second mounting hole 121 can also be set to be staggered so that the projection component 3 projects to the side and upwards, that is, projects the pattern to the outside of the housing component 1 as a whole, forming a large-area projection, and there is no limitation on this.

[0037] An optical cavity 122 is recessed on the side of the lower shell 12 away from the fan assembly 2. The second mounting hole 121 is opened on the lower shell 12 and communicates with the optical cavity 122. The air outlet 120 is formed on the outer periphery of the optical cavity 122 and is arranged in a grid shape.

[0038] The light source assembly 4 is mounted on the bottom of the lower housing 12 and housed inside the optical cavity 122, emitting light directly. The light source assembly 4 includes a driving module and a light source module 41. The light source module 41 is independent of the projection assembly 3 and both can emit direct light. The driving module is configured to drive at least one of the projection assembly 3 and the light source module 41 to emit light. In other words, the driving module achieves both illumination and projection for the fan light 100. Of course, the location of the driving module is not limited and can be adjusted according to different structures of the fan light 100.

[0039] Please refer to Figures 4 and 6. The projection assembly 3 includes a projection frame 31 and a projection module 32 and a light-emitting module 33 fixed in the projection frame 31. The projection module 32 is close to the first mounting hole 111, and the light-emitting module 33 is close to the second mounting hole 121. The projection frame 31 is hollow so that some of the light emitted by the light-emitting module 33 is projected onto the mounting surface after passing through the projection module 32 and the first mounting hole 111.

[0040] In this embodiment, the projection module 32 and the light-emitting module 33 are centrally located in a projection frame 31, making the installation method simpler. Of course, in other embodiments, the projection module 32 and the light-emitting module 33 can also be independent of each other, instead of being integrated into a projection component 3 through the projection frame 31, and there is no limitation on this.

[0041] Specifically, the projection frame 31 includes a first assembly part 311, a second assembly part 312, and a clamping part 313 connecting the first assembly part 311 and the second assembly part 312. The first assembly part 311 passes through the first assembly hole 111 and is partially exposed outside the first assembly hole 111, and the second assembly part 312 passes through the second assembly hole 121 and is partially exposed outside the second assembly hole 121. That is to say, the projection component 3 is installed through the mutual cooperation of the first assembly part 311 and the first assembly hole 111, the second assembly part 312 and the second assembly hole 121, and the projection function and the lighting function can be realized simultaneously through the first assembly hole 111 and the second assembly hole 121 set at different positions.

[0042] The portion of the first assembly part 311 exposed outside the first assembly hole 111 is defined as the first fastening part, and the portion of the second assembly part 312 exposed outside the second assembly hole 121 is defined as the second fastening part. The first fastening part fastens to the outer periphery of the first assembly hole 111, and the second fastening part fastens to the outer periphery of the second assembly hole 121. By setting the extension length of the clamping part 313, the projection frame 31 is fixed to the housing assembly 1. Of course, in other embodiments, other fixing methods can also be used, as long as the projection module 32 is fixed in the air cavity 10 and can be easily disassembled without affecting the projection and lighting effects.

[0043] The projection module 32 includes a first light-transmitting element 321 fixed within the first assembly portion 311, and a second light-transmitting element 322 and an imaging component 323 fixed within the clamping portion 313. In the extending direction of the receiving cavity, the first light-transmitting element 321, the imaging component 323, the second light-transmitting element 322, and the light-emitting module 33 are arranged sequentially vertically, so that a portion of the light emitted by the light-emitting module 33 passes sequentially through the second light-transmitting element 322, the imaging component 323, and the first light-transmitting element 321 before being projected onto the mounting surface. Preferably, the imaging component 323 is a film and a holder for fixing the film; this is a conventional technique and will not be described in detail. Of course, the image on the film can be changed as needed, and this is not limited.

[0044] The light-emitting module 33 includes a light source plate 330 and a first light-emitting element 331 fixed on the light source plate 330. The first light-emitting element 331 is disposed facing the second light-transmitting element 322. The light emitted by the first light-emitting element 331 passes through the second light-transmitting element 322, the imaging component 323 and the first light-transmitting element 321 in sequence, and projects the image of the imaging component 323 onto the mounting surface.

[0045] The second light-transmitting element 322 includes at least a first lens 3221 and a second lens 3222 spaced apart. At least one side of the first lens 3221 protrudes in an arc shape, and at least one side of the second lens 3222 is also arc-shaped. Light emitted from the first light-emitting element 331 enters the imaging component 323 in parallel after passing through the first lens 3221 and the second lens 3222. In other words, the first lens 3221 and the second lens 3222 primarily serve to correct the light. However, to ensure that the light enters the imaging component 323 in parallel, the degree of curvature of the arc surfaces of the first lens 3221 and the second lens 3222, the distance between them, or even increasing the number of lenses can all be adjusted according to the actual situation. There are no restrictions on these adjustments, as long as the light entering the imaging component 323 is parallel. Furthermore, the arc surface arrangement promotes light convergence and improves projection quality.

[0046] The first light-transmitting element 321 includes at least one lens to diffuse the light and further magnify the image set in the imaging component 323 to achieve a projection effect.

[0047] As shown in Figure 7, the light emission direction of the projection component 3 is opposite to each other. The side facing the first light-transmitting element 321 is for projection function, and the side facing the light-reflecting element 333 is for illumination function.

[0048] In this embodiment, the projection frame 31 has multiple slots inside for securing the first lens 3221, the second lens 3222, the imaging component 323, and the first light-transmitting element 321.

[0049] Please refer to Figure 5. The light-emitting module 33 also includes a second light-emitting element 332 disposed on the side of the light source plate 330 opposite to the first light-emitting element 331. The second light-emitting element 332 provides direct illumination through the second mounting hole 121.

[0050] In this embodiment, the light-emitting module 33 further includes a refractive element 333 disposed within the second assembly portion 312. The refractive element 333 is located below the second light-emitting element 332, so that the light emitted by the second light-emitting element 332 is emitted after passing through the refractive element 333. Preferably, the refractive element 333 is a prism plate to provide refraction of the light emitted by the second light-emitting element 332.

[0051] In summary, the fan light 100 of this application provides a first mounting hole 111 and a second mounting hole 121 on the upper shell 11 and the lower shell 12, respectively, and the first mounting hole 111, the second mounting hole 121 and the air cavity 10 are interconnected to form a receiving cavity. This allows the projection component 3 to be mounted in the receiving cavity and correspond to the first mounting hole 111 and the second mounting hole 121. Thus, while maintaining the air outlet function of the fan light 100, it is further compatible with the projection function, improving the user experience.

[0052] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
