[0025] In one embodiment of the present invention, reference Figure 1-3 , a projection device 100 is provided, comprising a fixing plate 10 and a driving control board 20 located at the bottom of the fixing plate 10. The projection device 100 also comprises a laser projection component and an aurora projection component.

[0026] In one embodiment, the laser projection assembly includes a laser motor 30 driven by the drive control board 20 , a grating plate 80 driven to rotate by the laser motor 30 , and a laser 60 for generating laser light and transmitting the laser light to the grating plate 80 .

[0027] The aurora projection assembly includes an aurora motor 40 driven by the drive control board 20 , an aurora sheet 94 driven to rotate by the aurora motor 40 , and a first aurora lamp board 90 and a second aurora lamp board 99 electrically connected to the drive control board 20 .

[0028] In the above embodiment, the laser 60 can be any type of laser, for example, a three-color laser, so that multiple colors can be displayed. When the laser motor 30 is running, the corresponding grating sheet 80 is driven to rotate synchronously, so that through the irradiation of the laser 60, various dynamic patterns on the grating sheet 80 can be projected through the irradiation of light, thereby forming a beautiful dynamic projection effect.

[0029] At the same time, in the above embodiment, when the aurora motor 40 is running, the aurora sheet 94 is also driven to rotate, and the corresponding first aurora lamp board 90 and the second aurora lamp board 99 can cause the corresponding aurora sheet 94 to project aurora patterns with different textures, and then through the linkage of multiple motors, multiple grating sheets and multiple lasers, users can choose a variety of dynamic lighting patterns and combine them into a variety of lighting atmospheres, which makes people more immersive. In addition, the projection device can realize dynamic aurora patterns with different textures, making the projected aurora patterns more dynamic and beautiful.

[0030] Since the laser motor 30, the laser 60, the aurora motor 40 and the corresponding control circuits generate a lot of heat during operation, in order to dissipate heat in time and ensure that the operating temperature of each component is kept within a normal range, a first heat sink 50 can be provided on the fixing plate 10. The first heat sink 50 includes a top heat sink 52 and a side heat sink 54 formed by bending from the edge of the top heat sink 52. A heat dissipation space is formed between the top heat sink 52, the side heat sink 54 and the fixing plate 10. The above-mentioned components are placed in the heat dissipation space, and through the cooperation of the top heat sink 52 and the side heat sink 54, the heat generated by the components set in the heat dissipation space during operation can be dissipated in time, thereby avoiding heat accumulation, causing the operating temperature of the components to rise rapidly, resulting in the components not being able to operate normally, or even causing the components to burn out.

[0031] Preferably, in order to further improve the heat dissipation effect, a second heat sink 70 may be placed on the top heat sink 52. Providing an additional heat sink can quickly dissipate the heat accumulated on the top heat sink 52, thereby preventing the temperature of the top heat sink 52 from rising sharply and causing the entire projection device to heat up.

[0032] In order to achieve a more dynamic and richer projection pattern effect, a plurality of the grating sheets 80 may be provided, each grating sheet 80 may have a different color pattern, and each aurora sheet 94 is provided above the second heat sink 70 to achieve heat dissipation.

[0033] In one embodiment, the laser motor 30 includes a first motor base 32 and a first output shaft 34 disposed on the first motor base 32 and driven to rotate; the first output shaft 34 passes through the fixing plate 10, the top heat sink 52 and the second heat sink 70 in sequence and is fixedly connected to the grating sheet 80. The first output shaft 34 is directly connected to the grating sheet 80, so when the laser motor 30 rotates, the grating sheet 80 also rotates with the first output shaft 34, and the color pattern on the grating sheet 80 can be dynamically presented by means of the projection of the laser 60 on the grating sheet 80.

[0034] The first motor base 32 is placed on the drive control board 20 and is electrically connected thereto. The drive control board 20 controls the laser motor 30, such as controlling the operating speed and frequency, the operating direction, the temperature and other parameters, and detects the above parameters of the laser motor 30 in real time, and controls it according to the specific values ​​of the parameters. Although in the above embodiment, the drive control board 20 is located on the first motor base 32, the utility model is not limited thereto, and the drive control board 20 can also be set at other appropriate positions as long as it can be electrically connected to the first motor base 32.

[0035] Preferably, in one embodiment, the laser 60 is located in the heat dissipation space and below the grating sheet 80. The laser 60 is used to generate high-quality, high-intensity and high-brightness lasers, so the laser 60 has a high power and naturally generates a lot of heat during operation. Therefore, it needs to be placed in the heat dissipation space to facilitate heat dissipation. In addition, this arrangement also greatly reduces the height of the entire projection device and further reduces the volume of the projection device.

[0036] Preferably, in one embodiment, the aurora motor 40 includes a second motor base 42 and a second output shaft 44 disposed on the second motor base 42 and driven to rotate by the second motor base 42; the second output shaft 44 sequentially passes through the fixing plate 10, the top heat sink 52 and the second heat sink 70 to be fixedly connected to the aurora sheet 94. When the aurora motor 40 is running, the second output shaft 44 located on the second motor base 42 rotates, thereby driving the aurora sheet 94 to rotate, so that the rotating display effect of the aurora sheet 94 is achieved.

[0037] Optionally, in another embodiment, the second motor base 42 is disposed on the drive control board 20 and is electrically connected thereto. Similarly, the drive control board 20 controls the Aurora motor 40, such as controlling the operating speed and frequency, the operating direction, the temperature and other parameters, and detects the above parameters of the Aurora motor 40 in real time, and controls it according to the specific values ​​of the parameters. Although in the above embodiment, the drive control board 20 is located on the second motor base 42, the utility model is not limited thereto, and the drive control board 20 can also be disposed at other appropriate locations, as long as it can be electrically connected to the second motor base 42.

[0038] In one embodiment, the aurora projection assembly further includes an aurora lens 96, and the aurora lens 96 is disposed above the aurora sheet 94. The aurora lens 96 is used to converge the light from the aurora sheet 94, thereby forming a better light display effect.

[0039] Those skilled in the art will appreciate that the various operations, methods, steps, measures, and schemes in the processes discussed in this application may be alternated, altered, combined, or deleted. Further, other steps, measures, and schemes in the various operations, methods, and processes discussed in this application may also be alternated, altered, rearranged, decomposed, combined, or deleted. Further, the steps, measures, and schemes in the prior art that are similar to those disclosed in this application may also be alternated, altered, rearranged, decomposed, combined, or deleted.

[0040] The above description is only a partial implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
