[0024] To make the objectives, features, and advantages of this application more apparent and understandable, the following further elaborates on this application in conjunction with the accompanying drawings and specific implementation manners. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts belong to the scope of protection of this application.

[0025] The inventor found through analyzing the prior art that existing projectors only have the projection function and are relatively single in function. The starry sky lamp has a working principle similar to that of a projector. If a starry sky projection scene is desired, a starry sky lamp needs to be purchased separately, and the effect of the starry sky lamp cannot be directly applied to the projector.

[0026] Refer to Figures 1-3 , which shows a projector with a starry sky lamp provided by an embodiment of this application, including a housing 111, a projection lens group, and a starry sky lens 101; the projection lens group is disposed inside the housing 111, the housing 111 is provided with a slide rail, one end of the slide rail corresponds to the projection position of the projection lens group, and the starry sky lens 101 is disposed on the slide rail; when the projector is in the starry sky lamp mode, the starry sky lens moves to a position corresponding to the projection position of the projection lens group through the slide rail.

[0027] In the embodiment of this application, in contrast to the drawback that existing projectors are single in function and do not have the starry sky lamp projection function, this application provides a solution for installing a starry sky lens to project a starry sky or aurora. Specifically, it is a projector with a starry sky lamp, including a housing 111, a projection lens group, and a starry sky lens 101; the projection lens group is disposed inside the housing 111, the housing 111 is provided with a slide rail, one end of the slide rail corresponds to the projection position of the projection lens group, and the starry sky lens 101 is disposed on the slide rail; when the projector is in the starry sky lamp mode, the starry sky lens moves to a position corresponding to the projection position of the projection lens group through the slide rail. By setting the starry sky lens 101, the projector is equipped with the function of a starry sky lens, enhancing the applicability of the projector and enabling users to have more experiences while using the projector.

[0028] It should be noted that by adjusting the relative positions of the starry sky lens 101 and the projection lens group, the conversion between the starry sky light and the projector function can be achieved. Also, the starry sky lens 101 can be directly removed or installed to realize the conversion between the starry sky light and the projector function. Design the switching function solution according to actual needs. When using the projection mode, as Figure 2 shown, move the starry sky lens 101 out of the projection position through the slide rail, and the projection function can be normally played.

[0029] In a specific implementation, the structure of the starry sky lens is as Figure 3 shown. By using the optical surface profile, the projected starry sky or aurora and other images can be magnified at a short distance to achieve effects such as aurora and starry sky.

[0030] Next, a projector with a starry sky light in this exemplary embodiment will be further described.

[0031] In an embodiment of the present application, the projection lens group includes a projection LED light source 104, a first projection lens 105, a first Fresnel lens 106, a polarizer 107, a liquid crystal panel 108, a second Fresnel lens 109, a reflector 110, and a second projection lens 102;

[0032] The projection LED light source 104, the first projection lens 105, the first Fresnel lens 106, the polarizer 107, the liquid crystal panel 108, and the second Fresnel lens 109 are sequentially stacked. The second projection lens 102 is connected to the starry sky lens 101. The reflector 110 is disposed on top of the second Fresnel lens 109, and the reflector 110 is used to reflect the image transmitted through the second Fresnel lens 109 to the second projection lens 102.

[0033] It should be noted that the projection LED light source 104, the first projection lens 105, the first Fresnel lens 106, the polarizer 107, the liquid crystal panel 108, the second Fresnel lens 109, the reflector 110, and the first projection lens together constitute the screen projection function part of the projector to realize the screen projection function. By connecting the starry sky lens 101 to the second projection lens 102, the starry sky lens 101 magnifies and diverges the light effect projected by the second projection lens 102 to realize the starry sky light function.

[0034] In an embodiment of the present application, a radiator 103 is further included;

[0035] The radiator 103 is disposed at the bottom of the LED light source 104, and the radiator 103 is used to cool the projection lens group.

[0036] It should be noted that the radiator 103 is used to dissipate heat inside the projector to protect the internal components. Generally, a fan-type heat dissipation device is selected for the radiator 103 to ensure the temperature inside the projector.

[0037] In an embodiment of the present application, the housing is provided with heat dissipation holes corresponding to the position of the radiator 103.

[0038] It should be noted that gas exchange is carried out through the heat dissipation holes, which facilitates the radiator to cool the inside.

[0040] The housing is provided with a control panel, and the controller is electrically connected to the control panel.

[0041] It should be noted that the projection lens group and the starry sky lens are controlled by the controller to adjust their relative positions, so as to facilitate switching of projection modes, focal lengths, etc. At the same time, a control panel is also provided, and the user can operate the projector through the control panel and adjust it in time according to the usage scenario.

[0042] In an embodiment of the present invention, the control panel is provided with a starry sky projection switching button.

[0043] It should be noted that adding a shortcut key facilitates quick switching of projection modes and improves the user experience.

[0044] In an embodiment of the present invention, the starry sky lens 101 is detachably connected to the slide rail.

[0045] It should be noted that by removing the starry sky lens 101, it is convenient to use the functions of the projector, reduce the influence of the starry sky lens 101 on the normal projection function, and at the same time facilitate the storage of the starry sky lens 101, protect the starry sky lens 101, and reduce scratches.

[0046] In an embodiment of the present invention, the starry sky lens 101 is an aurora mirror or a starry sky mirror.

[0047] It should be noted that by setting the edges and corners of different starry sky lenses, the projection state of the starry sky light mode is changed.

[0048] In an embodiment of the present invention, an electric motor is further included. The electric motor is arranged on the slide rail, and the electric motor is used to adjust the position of the starry sky lens.

[0049] It should be noted that the electric motor is connected to the controller, and the controller controls the electric motor to adjust the position of the starry sky lens 101, moving the starry sky lens 101 to the working position or the projection position, which facilitates the user to achieve non-contact operation.
