[0002] With the development of society, people's quality of life is getting higher and higher. In various different environmental occasions, various different lamps are usually used for decoration and lighting. Due to the relatively fast pace of modern life, people don't have much time to go to the wild to appreciate the magnificent night sky of nature. Coupled with factors such as weather and geographical location, it is usually very difficult for people to see various strange astronomical beauty scenes. Therefore, people have designed some lamps that simulate starry sky scenes. Currently, the star projection lamps on the market generally use the direct light source method to achieve the projection of light effects. However, this technology requires a glass lens of a relatively large size, and the lens itself has high manufacturing requirements and is heavy, which is likely to affect the shape and structure design of the product. In addition, the glass lens is also relatively thick and heavy, and it is extremely easy to be damaged when the product falls, affecting the service life of the product. Summary of the Invention

[0030] With the above structural arrangement, during use, the light rays emitted by the light effect projection light source are projected onto the light effect reflecting surface of the light effect reflector. Since the light effect reflecting surface is a diffuse reflection surface, the light rays undergo diffuse reflection. At the same time, since the light effect reflecting surface surrounds a plurality of light effect projection light sources and each light effect projection light source is arranged towards the light effect reflecting surface; at this time, when the light effect reflector or the light effect projection light source rotates, a multi-light shadow effect can be formed, thereby projecting the light effect of a starry sky lamp aurora, eliminating structures such as glass lenses in existing starry sky lamp products, simplifying the structural design of the product, and reducing the weight and vulnerability rate of the product.

[0031] In this embodiment, the light projection structure further includes a first graphic light and shadow projection device 2, the first graphic light and shadow projection device 2 is used to project a graphic light and shadow effect, and the projection area of the light effect projection device 1 and the projection area of the first graphic light and shadow projection device 2 intersect and overlap with each other. Among them, the first graphic light and shadow projection device can project graphic lights and shadows such as stars and moons. Since the light effect projection device 1 projects the light effect of the aurora and the projection area of the light effect projection device intersects and overlaps with the projection area of the first graphic light and shadow projection device, the aurora light effect and the graphic light effect intersect and overlap with each other, thereby forming the light effect of a starry night sky scene.

[0032] In this embodiment, the light projection structure further includes a first carrier 14, a plurality of the light effect projection light sources 13 are arranged on the first carrier 14, the driving device 12 is a first motor, and the first carrier 14 is arranged on the output shaft of the first motor.

[0033] Among them, the light effect reflector can be an annular reflector in the shape of a horn, and the first carrier is located inside the annular reflector, that is, the light effect projection light source is located inside the annular reflector, so as to form a light projection structure from the center to the periphery.

The first graphic light and shadow projection device 2 is provided with a differential gear set 21. The differential gear set 21 meshes with the first gear 31. Through the above structural arrangement, the second motor can drive the light effect reflector to rotate, that is, the light effect reflector and the light effect projection light source can rotate simultaneously, further enhancing the light effect of the aurora. At the same time, the second motor can drive the first graphic light and shadow projection device to rotate through the differential gear set, that is, the graphic light and shadow projected by the first graphic light and shadow projection device can also rotate. And due to the setting of the differential gear set, there is a rotational speed difference between the rotation of the graphic light and shadow and the aurora light effect, so that the starry sky lamp can project the effect of a moving starry sky, further enhancing the user experience.

[0035] In this embodiment, the first graphic light and shadow projection device 2 includes a light guide sleeve 22. A graphic light source 23 is provided at one end of the light guide sleeve 22, and a grating sheet 24 is provided at the other end.

The third gear 211 meshes with the first gear 31, and the fourth gear 212 is provided on the light guide sleeve 22. Through the above structural arrangement, the projection effect of the graphic light and shadow is realized. Moreover, the radial dimensions of the third gear and the fourth gear are both inconsistent with the radial dimension of the first gear, so as to achieve the differential effect.

[0036] In this embodiment, the light projection structure further includes a light-transmitting cover 7. The light-transmitting cover 7 covers the light effect reflector 11, and a plurality of edges 71 are convexly provided on the inner wall of the light-transmitting cover 7. Through the above structural arrangement, the light effect reflector and the light-transmitting cover cooperate with each other, so as to realize more types of light effect. Among them, there can be various structural forms of the light-transmitting cover, which will not be listed one by one here.

[0037] In this embodiment, the light projection structure further includes a circuit board 10, and the circuit board is electrically connected to the first motor, the second motor, the graphic light source, and the light effect projection light source. Among them, the graphic light source and the light effect projection light source can both be laser light sources or RGB light sources, or a plurality of light effect projection light sources can also be an array combination of a plurality of laser light sources or a plurality of RGB light sources interleaved. Of course, there are also various forms of the array, which will not be listed one by one here.

[0038] Embodiment 2:

[0039] Referring to Figure 1 , Figures 3 to 7 , a reflective dynamic light projection device, including a light effect projection device 1, the light effect projection device 1 includes a light effect reflector 11, a driving device 12, and a plurality of light effect projection light sources 13. The light effect reflector 11 is provided with a light effect reflecting surface 114, and the light effect reflecting surface 114 is provided with concave and convex textures so that the light effect reflecting surface 114 is a diffuse reflection surface; the outer surface of the light effect reflector 11 is the light effect reflecting surface 114, and each of the light effect projection light sources 13 is sequentially arranged around the light effect reflector 11, and each of the light effect projection light sources 13 is directed towards the light effect reflecting surface 13 of the light effect reflector 11 to realize the light effect projection device 1 projecting a light effect; the light effect reflector 11 or a plurality of the light effect projection light sources 13 are connected to the driving device 12 so that the driving device 12 can drive the light effect reflector 11 or a plurality of the light effect projection light sources 13 to rotate.

[0040] With the above structural arrangement, during use, the light rays emitted by the light effect projection light source are projected onto the light effect reflecting surface of the light effect reflector. Since the light effect reflecting surface is a diffuse reflection surface, the light rays are diffusely reflected. At the same time, since each light effect projection light source is sequentially arranged around the light effect reflector, and each light effect projection light source is directed towards the light effect reflecting surface; at this time, when the light effect reflector or the light effect projection light source rotates, a multi-light shadow effect can be formed, thereby projecting the light effect of a starry sky lamp aurora, eliminating structures such as glass lenses in existing starry sky lamp products, simplifying the structural design of the product, and reducing the weight and vulnerability rate of the product.

[0041] The light projection structure further includes a first graphic light and shadow projection device 2, the first graphic light and shadow projection device 2 is used to project a graphic light and shadow effect, and the projection area of the light effect projection device 1 and the projection area of the first graphic light and shadow projection device 2 intersect and overlap with each other. Among them, the first graphic light and shadow projection device can project graphic lights and shadows such as stars and moons. Since the light effect projection device 1 projects the light effect of the aurora, and the projection area of the light effect projection device intersects and overlaps with the projection area of the first graphic light and shadow projection device, the aurora light effect and the graphic light effect intersect and overlap with each other, thereby forming the light effect of a starry night sky scene.

[0042] Of course, a second graphic light and shadow projection device 101 can also be set. The second graphic light and shadow projection device can project graphic lights and shadows such as stars and moons; moreover, the second graphic light and shadow projection device does not rotate, while the first graphic light and shadow projection device rotates. At the same time, the projection areas of the light effect projection device, the first graphic light and shadow projection device, and the second graphic light and shadow projection device overlap with each other, so that the rotating aurora light effect, the rotating graphic light effect, and the non-rotating graphic light effect overlap with each other, thus forming a light effect of a star and moon night sky scene with a richer sense of hierarchy.

[0043] In this embodiment, the light projection structure further includes a second carrier 4. The driving device 12 is a third motor. The output shaft of the third motor passes through the second carrier 4 and is connected to the light effect reflector 11. A plurality of the light effect projection light sources 13 are arranged on the second carrier 4. Through the above structural arrangement, the third motor can drive the light effect reflector to rotate, thereby realizing the rotation of the light effect reflecting surface and achieving the projection effect of the aurora light effect.

[0044] Among them, the light effect reflector can be in a conical shape, a hemispherical shape, etc. The concave and convex texture can be a regular or irregular texture. For example, it can be a spherical, conical, polygonal, etc. concave and convex texture. Of course, both the structural form of the light effect reflector and the structural form of the concave and convex texture can be various, and will not be listed one by one here.

[0045] In this embodiment, the first graphic light and shadow projection device 2 includes a light guide sleeve 22. An installation groove 25 is arranged at one end of the light guide sleeve 22. A graphic light source 23 is inserted into the installation groove 25. A grating sheet 24 is arranged at the other end of the light guide sleeve 22, so as to realize the projection of the graphic light and shadow.

[0046] In this embodiment, the light projection structure further includes a fifth gear 5 and a sixth gear 6 that mesh with each other. The fifth gear 5 is arranged on the output shaft of the third motor. The sixth gear 6 is arranged on the light guide sleeve 22, and the radial dimension of the fifth gear 5 is inconsistent with the radial dimension of the sixth gear 6, so that the fifth gear 5 and the sixth gear 6 form a differential structure. Through the above structural arrangement, the third motor can drive the first graphic light and shadow projection device to rotate through the fifth gear and the sixth gear, that is, the graphic light and shadow projected by the first graphic light and shadow projection device can also rotate. And because the radial dimension of the fifth gear is inconsistent with the radial dimension of the sixth gear, forming a differential structure, there is a rotational speed difference between the rotation of the graphic light and shadow and the aurora light effect, so that the starry sky lamp can project the effect of a moving starry sky, further improving the user experience.

[0047] In this embodiment, the light projection structure further includes a light-transmitting cover 7, the light-transmitting cover 7 covers the light effect reflector 11, and a plurality of edges 71 are convexly provided on the inner wall of the light-transmitting cover 7. Through the above structural arrangement, the light effect reflector and the light-transmitting cover cooperate with each other to achieve more types of light effect. And, no edge is provided at the position of the light-transmitting cover corresponding to the light effect projection light source. Among them, the structural form of the light-transmitting cover can be various, which will not be listed one by one here.

[0048] In this embodiment, the light projection structure further includes a circuit board, and the circuit board is electrically connected to the third motor, the graphic light source, and the light effect projection light source. Among them, the graphic light source and the light effect projection light source can both be laser light sources or RGB light sources, or a plurality of light effect projection light sources can also be an array combination of a plurality of laser light sources or a plurality of RGB light sources alternating with each other. Of course, the form of the array can also be various, which will not be listed one by one here.

At the same time, components such as the light effect projection device, the first graphic light and shadow projection device, the second graphic light and shadow projection device, and the circuit board can all be arranged in the housing.

[0051] Since the starry sky lamp of this embodiment includes the above-mentioned reflective dynamic light projection device, through the setting of this light projection structure, during use, the light emitted by the light effect projection light source is projected onto the light effect reflection surface of the light effect reflector. Since the light effect reflection surface is a diffuse reflection surface, the light undergoes diffuse reflection. At the same time, since each light effect projection light source is sequentially arranged around the light effect reflector, and each light effect projection light source is arranged towards the light effect reflection surface; at this time, when the light effect reflector or the light effect projection light source rotates, a multi-light shadow effect can be formed, thereby projecting the light effect of the starry sky lamp's aurora, eliminating structures such as glass lenses in existing starry sky lamp products, simplifying the structural design of the product, and reducing the weight and vulnerability rate of the product.
