Description

Technical Field

[0001] The present invention belongs to the technical field of projection devices, and particularly relates to a starry sky projection lamp with a meteor effect. Background Art

[0002] In traditional technologies, projection devices have long been restricted in form and have relatively single functions. With the development of society, people's requirements for art and the beautification of the surrounding living environment are getting higher and higher. However, due to the accelerating pace of modern people's lives and their relatively full time arrangements, they don't have much time to go outdoors to enjoy the beautiful starry sky in nature. Moreover, due to factors such as weather and living environment, people have fewer opportunities to view the starry sky, or even galaxies in the starry sky, and are subject to more restrictions, which is relatively inconvenient.

[0003] To meet people's needs, there are also some starry sky lamps on the market currently. Using projection technology, patterns such as a starry sky with a meteor effect are projected onto the walls or roofs of homes. The projected image can show a magnificent starry sky with a popular effect. Currently, the projection lamp uses two projection components to project the starry sky and meteors respectively and superimpose them to form a starry sky pattern with a popular effect. Among them, the projection component for projecting meteors usually includes: an objective lens holder, which is provided with a projection channel penetrating up and down, and a first light-transmitting slit is provided at the bottom of the projection channel; a lens installed on the objective lens holder, which is arranged at the opening at the top of the projection channel; a turntable rotatably installed at the bottom of the objective lens holder, a second light-transmitting slit is provided on the turntable body, and the turntable body sweeps across the projection channel during the rotation of the turntable; and a light source is provided at the bottom of the turntable. By rotating the turntable so that the second light-transmitting slit on the turntable body aligns with the first light-transmitting slit at the bottom of the projection channel, the light emitted by the light source passes through the second light-transmitting slit and the first light-transmitting slit in sequence and projects a meteor pattern.

[0004] However, the traditional light-transmitting slit is set as one, and the meteor pattern only appears when the light-transmitting slit aligns with the projection channel. The appearance time of the meteor pattern is short, the number is small, and it is not natural. In order to increase the appearance time of the meteor pattern, people will set multiple light-transmitting slits on the turntable body. Through the phenomenon of visual persistence of people, the appearance duration of the meteor pattern becomes longer, but the phenomenon of small number and unnaturalness of the meteor pattern still cannot be overcome. Summary of the Invention

[0005] The main object of the present invention is to provide a starry sky projection lamp with a meteor effect. At least one first light-transmitting slit is provided on the side surface of the light-shielding cylinder, and at least one second light-transmitting slit is provided on the light-shielding sheet. The second light-transmitting slit is arranged corresponding to the first projection channel. During the rotation of the light-shielding cylinder driven by the first driving component, the first light-transmitting slit can coincide with the second light-transmitting slit. The light emitted by the first light source sequentially passes through the first light-transmitting slit, the second light-transmitting slit and the first convex lens to project a meteor pattern to the outside. In the present invention, it overcomes the shortcomings of the traditional projection lamp that meteors only appear at the moment when the first light-transmitting slit and the second light-transmitting slit are aligned, and there are no meteors at other times, and the appearance time of the meteors is short. By utilizing the curved surface characteristics of the light-shielding cylinder, the first light-transmitting slit on the light-shielding cylinder presents curved surface characteristics, thereby prolonging the coincidence time of the first light-transmitting slit and the second light-transmitting slit, making the appearance of the meteor pattern continuous and long-lasting, and making it more in line with natural characteristics. Moreover, when the special effect of a meteor shower is desired, a plurality of first light-transmitting slits can be continuously arranged at a certain distance on the light-shielding cylinder, and a plurality of second light-transmitting slits are provided on the light-shielding sheet, so that a plurality of first light-transmitting slits and a plurality of second light-transmitting slits can coincide and appear simultaneously, thereby presenting a meteor shower.

[0035] In traditional technologies, projection devices have long been often restricted by form and have relatively single functions. With the development of society, people's requirements for art and the beautification of the surrounding living environment are also getting higher and higher. However, with the accelerating pace of modern people's lives and relatively full time arrangements, there is not much time to go outdoors to enjoy the beautiful starry sky in nature; moreover, due to factors such as weather and living environment, people have fewer opportunities to watch the starry sky, or even galaxies in the starry sky, and are subject to more restrictions, which is relatively inconvenient.

[0036] To meet people's needs, some starry sky lights have emerged on the market. Using projection technology, patterns such as a cosmic starry sky with a meteor effect are projected onto the walls or ceilings of homes. One can see a starry sky full of brilliant meteors in the projection. Currently, projection lights use two projection components to project the starry sky and meteors respectively and superimpose them to form a starry sky pattern with a meteor effect. Among them, the projection component for projecting meteors usually includes: an objective lens seat with a vertically penetrating projection channel, and a first light-transmitting slit is provided at the bottom of the projection channel; a lens installed on the objective lens seat, and the lens is provided at the opening at the top of the projection channel; a turntable rotatably installed at the bottom of the objective lens seat, a second light-transmitting slit is provided on the turntable body, and the turntable body sweeps across the projection channel during the rotation of the turntable; and a light source is provided at the bottom of the turntable. By rotating the turntable so that the second light-transmitting slit on the turntable body aligns with the first light-transmitting slit at the bottom of the projection channel, the light emitted by the light source passes through the second light-transmitting slit and the first light-transmitting slit in sequence and projects a meteor pattern.

[0037] However, the traditional light-transmitting slit is set as one, and the meteor pattern only appears when the light-transmitting slit aligns with the projection channel. The appearance time of the meteor pattern is short, the number is small, and it is not natural. In order to increase the appearance time of the meteor pattern, people will set multiple light-transmitting slits on the turntable body. Through the phenomenon of visual persistence of people, the appearance duration of the meteor pattern becomes longer, but the phenomenon of few and unnatural meteor patterns still cannot be overcome.

[0038] In the present invention, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 shown, an embodiment of the present invention provides a starry sky projection lamp with a meteor effect, which includes: a first projection component 10, and the first projection component 10 includes: a first projection housing 11, and a first projection channel 111 is provided in the first projection housing 11;

The light emitted by the first light source sequentially passes through the first light-transmitting slit 121, the second light-transmitting slit 151 and the first convex lens 14 to project a meteor pattern to the outside world.

[0045] In the present invention, it overcomes the shortcomings that in the traditional projection lamp, a meteor only appears at the moment when the first light-transmitting slit 121 and the second light-transmitting slit 151 are aligned, and no meteor appears at other times, and the appearance time of the meteor is short. By using the curved surface characteristic of the light-shielding cylinder 12, the first light-transmitting slit 121 on the light-shielding cylinder 12 presents a curved surface characteristic, so as to extend the coincidence time of the first light-transmitting slit 121 and the second light-transmitting slit 151, making the appearance of the meteor pattern continuous and long-lasting, making it more in line with natural characteristics.
