Referring to fig. 5, fig. 5 is an exploded view of the light and shadow assembly of the other structure shown in fig. 4. The light and shadow assembly 20 may include a light transmissive plate 21, a first grating 22, a second grating 23, a yellow light source 24, and a background light source 25. The light-transmitting plate 21 is parallel to the top plate 11 and spaced apart from the top plate 11, and the light-transmitting plate 21 is rotatable about an axis. The first grating 22 is connected to the light-transmitting plate 21 and is located on the axis of rotation of the light-transmitting plate 21, and the second grating 23 is spaced from the first grating 22, so that the second grating 23 can rotate relative to the first grating 22 due to the fact that the light-transmitting plate 21 can rotate around the axis. The yellow light source 24 is located on a side of the light-transmitting plate 21 facing away from the second grating 23, and the first light emitted by the yellow light source 24 can sequentially pass through the first grating 22 and the second grating 23, so as to generate a plurality of continuously moving light spots. The background light source 25 is located on the side of the transparent plate 21 where the yellow light source 24 is located, and the second light emitted by the background light source 25 can pass through the transparent plate 21 to generate a variegated background light shadow.

In other words, the second grating 23 is spaced from the first grating 22, and the second grating 23 is rotatable relative to the first grating 22. The yellow light source 24 is located at a side of the first grating 22 facing away from the first grating 22, and light emitted by the yellow light source 24 can sequentially pass through the first grating 22 and the second grating 23 for generating a plurality of moving yellow spots. The light-transmitting plate 21 rotates around the optical axis of the yellow light source 24, and the second grating 23 is connected to the light-transmitting plate 21, so that the second grating 23 rotates relative to the first grating 22; the background light source 25 is located on the same side of the transparent plate 21 where the yellow light source 24 is located, and the light emitted by the background light source 25 can pass through the transparent plate 21 to generate a variegated background light shadow.

Referring to fig. 6, fig. 6 is a schematic front view of the light-transmitting plate in the light-shadow assembly shown in fig. 5. The light-transmitting plate 21 has an uneven surface for enabling the passing light to exhibit a variegated light effect. Specifically, the light-transmitting plate 21 may include a substrate 211 and a plurality of protruding ribs 212 protruding from the surface of the substrate 211, where the plurality of protruding ribs 212 may be arranged at intervals or may be arranged alternately, and is not limited herein. In one embodiment, the light-transmitting plate 21 may be a water glass.

In this embodiment, the top plate 11 is circular in shape, and the light-transmitting plate 21 is circular in shape and is disposed coaxially with the top plate 11. The light-transmitting plate 21 is rotatable about its central axis, and the first grating 22 is disposed at the central position of the light-transmitting plate 21. The first light emitted from the yellow light source 24 can pass through the center of the light-transmitting plate 21, and the first light can always pass through the first grating 22 regardless of the rotation of the light-transmitting plate 21. The second light emitted from the background light source 25 can pass through the light-transmitting plate 21, and the second light emitted from the background light source 25 can be converted into a continuous, mottled light shadow as the light-transmitting plate 21 rotates.

In other embodiments, the top plate 11 may be circular in shape, the light-transmitting plate 21 may be circular in shape, and the center line of the light-transmitting plate 21 may be parallel to the center line of the top plate 11, that is, the light-transmitting plate 21 and the top plate 11 are not coaxially disposed. The light-transmitting plate 21 rotates around its center line as an axis, and the first grating 22 is disposed at the center of the light-transmitting plate 21. The first light emitted from the yellow light source 24 can pass through the center of the light-transmitting plate 21, and the first light can always pass through the first grating 22 regardless of the rotation of the light-transmitting plate 21. Accordingly, the background light source 25 is located within the light-transmitting plate 21, and the second light emitted by the background light source 25 can be converted into a continuous, mottled light shadow as the light-transmitting plate 21 rotates.

In still other embodiments, the light-transmitting plate 21 may also be square, triangular, or other polygonal in shape. The light-transmitting plate 21 can rotate with any straight line perpendicular to the light-transmitting plate 21 as an axis, and the first grating 22 is disposed at the axis position of rotation of the light-transmitting plate 21. The first light emitted from the yellow light source 24 can pass through the rotation axis position of the light-transmitting plate 21, and the first light can always pass through the first grating 22 regardless of the rotation of the light-transmitting plate 21. In one embodiment, the rotation axis of the light-transmitting plate 21 is located at the geometric center of the light-transmitting plate 21, so that on one hand, the rotation stability of the light-transmitting plate 21 can be ensured, and on the other hand, the second light emitted by the background light source 25 can be always located within the range of the light-transmitting plate 21, thereby improving the continuity and stability of the background light shadow.

Further, the light-transmitting plate 21 is provided with a fixing hole 210 at a position corresponding to the axis of rotation thereof, and the first grating 22 can be embedded in the fixing hole 210, so that the first light emitted by the yellow light source 24 does not need to pass through the light-transmitting plate 21 and directly passes through the first grating 22.

Still further, the shadow assembly 20 may further include a drum 26, where the drum 26 is disposed through the fixing hole 210 and fixedly connected to the light-transmitting plate 21. Drum 26 may rotate light-transmitting plate 21 about the axis of drum 26. First grating 22 may be disposed on a side of drum 26 adjacent to second grating 23, and a first light emitted from yellow light source 24 may sequentially pass through drum 26, first grating 22, and second grating 23 to generate a plurality of moving yellow spots.

It will be appreciated that the first light beam from the yellow light source 24 is able to generate a plurality of stripe-shaped laser beams when passing through the first grating 22, and the stripe-shaped laser beams are cut to form a plurality of light spots when passing through the second grating 23. When the first grating 22 is static relative to the second grating 23, the light spots are in a static state, so that a firefly static picture can be generated; when the first grating 22 rotates relative to the second grating 23, the positions of the plurality of light spots are changed continuously, and a flying picture in the firefly can be generated. Further, the faster the first grating 22 rotates relative to the second grating 23, the faster the position change speed of the plurality of light spots, that is, the faster the firefly flies. In other words, the flying speed of the firefly can be adjusted by adjusting the rotation speed of the first grating 22 relative to the second grating 23.

The second grating 23 is disposed at one side of the top plate 11 and corresponding to the first through hole 111 of the top plate 11 such that the second grating 23 can be disposed at a distance from the first grating 22. In this embodiment, the first through hole 111 is located at the center of the top plate 11 so that the second grating 23 can be disposed opposite to the first grating 22.

The yellow light source 24 may be a yellow laser light source, and in particular, the laser light source has advantages of condensed light beam, high brightness, good color, low energy consumption, long service life, and small volume. The yellow light source 24 is disposed corresponding to the first through hole 111 of the top plate 11, that is, the position of the laser light source relative to the first through hole 111 is not changed, so that the first light emitted by the yellow light source 24 can sequentially pass through the first grating 22 and the second grating 23 and then be emitted from the first through hole 111.

The background light source 25 adopts an LED light source, so that the LED light source has the advantages of low power consumption, long service life and low carbon and environmental protection, and on the other hand, the color and the brightness of the LED light source are adjustable, so that different backgrounds can be conveniently rendered. The background light source 25 is disposed corresponding to the second through hole 112, that is, the position of the background light source 25 relative to the second through hole 112 is not changed, so that the second light emitted by the background light source 25 can pass through the light-transmitting plate 21 and then be emitted through the second through hole 112.

Referring to fig. 7, fig. 7 is an exploded view of the bracket in the firefly atmosphere simulation device shown in fig. 4. The firefly atmosphere simulation device 100 may further comprise a bracket 60, wherein the bracket 60 is used for fixing the light and shadow assembly 20. Specifically, the bracket 60 may include first and second support plates 61 and 62 disposed opposite to each other at a distance, and a connection post 63 vertically connected to the first and second support plates 61 and 62. Wherein the first support plate 61 is stacked with the top plate 11 and fixed with the top plate 11 by a fixing member such as a screw, so that the bracket 60 is fixedly connected with the housing 10.

Wherein the first support plate 61 is provided with a third through hole 611 corresponding to the first through hole 111 and a fourth through hole 612 corresponding to the second through hole 112. The second grating 23 is embedded in the third through hole 611 of the first support plate 61, so that the first light emitted by the yellow light source 24 sequentially passes through the drum 26, the first grating 22 and the second grating 23 and then is emitted through the first through hole 111. The second light emitted by the background light source 25 passes through the light-transmitting plate 21 and is disposed with the second through hole 112 via the fourth through hole 612.

As can be appreciated, the thermal light source of the laser light source, the light beam is condensed, the temperature is high and the brightness is high; the LED light source is a cold light source, and the light is dispersed and the brightness is lower. In order to reduce the mutual interference of the light and temperature of the yellow light source 24 and the background light source 25, the yellow light source 24 and the background light source 25 are arranged in a staggered manner.

Specifically, the yellow light source 24 is disposed on a side of the second support plate 62 facing away from the first support plate 61 and is connected to the heat dissipation assembly 30, so that the heat dissipation assembly 30 can reduce the temperature of the yellow light source 24 and improve the reliability of the yellow light source 24. The second support plate 62 is provided with a light hole 621, the light hole 621 and the fixing hole 210 on the light plate 21 are coaxially arranged with the first through hole 111 on the top plate 11, and the first light emitted by the yellow light source 24 can be projected onto the background wall after passing through the light hole 621, the first grating 22 in the fixing hole 210 and the second grating 23 in the first through hole 111 in sequence, so as to generate a plurality of yellow light spots.

Since the LED light source of the background light source 25 is a cold light source, the light is dispersed and the brightness is low, the background light source 25 is disposed between the second support plate 62 and the first support plate 61, and the background light source 25 is close to the light-transmitting plate 21, so as to reduce the emergent distance of the second light emitted by the background light source 25, and enable as much second light to pass through the light-transmitting plate 21 as possible. Specifically, the backlight 25 may include a base 251 and a lamp 252 fixed on the base 251, where the base 251 is fixed on a side of the second support plate 62 facing the first support plate 61, and is used to support and fix the lamp 252 on one hand, and to bring the lamp 252 close to the light-transmitting plate 21 on the other hand.

With reference to fig. 2 to 5, in the present embodiment, the light and shadow assembly 20 further includes a driving member 27, wherein the driving member 27 is connected to the drum 26 for driving the drum 26 to rotate, so as to drive the light-transmitting plate 21 and the first grating 22 to rotate synchronously. Specifically, the driving member 27 is fixed to a side of the second support plate 62 facing the top plate 11, and the driving member 27 is configured to drive the drum 26 to rotate around the axis of the drum 26, on the one hand, and to support the light-transmitting plate 21 and the first light beam, on the other hand. In this embodiment, the driving member 27 is a stepper motor, and the stepper motor can control the light-transmitting plate 21 and the first grating 22 to rotate at a constant speed, and can also control the light-transmitting plate 21 and the first grating 22 to rotate at a reduced speed or at a reduced speed, which is not particularly limited herein.

The light and shadow assembly 20 may further include an amplifying lens 28, where the amplifying lens 28 is disposed on a side of the light-transmitting plate 21 away from the background light source 25 and corresponding to the background light source 25, and the amplifying lens 28 is used for amplifying the background light and shadow of the background light source 25. Specifically, the magnifying lens 28 is embedded in the fourth through hole 612 of the first support plate 61 and at least partially located in the second through hole 112 of the top plate 11, so that the second light emitted by the background light source 25 can be emitted through the magnifying lens 28.

It can be appreciated that the projected area of the second light beam emitted by the background light source 25 after passing through the first through hole 111 is greatly affected by the projection distance, and the smaller the projection distance is, the smaller the projected area is, so that the light shadow assembly 20 is not beneficial for use in a small space. In this embodiment, the magnifying lens 28 may be embedded in the second through hole 112, so as to refract the light passing through the magnifying lens 28. Specifically, the magnifying lens is a convex lens, and the convex lens can uniformly refract the second light beam to the periphery, so as to amplify the background light shadow of the second light beam, so that the light shadow assembly 20 can have a larger projection area even under the condition of a smaller projection distance.

Referring to fig. 8, fig. 8 is a schematic perspective view of a light collecting member in the light and shadow assembly shown in fig. 5. Further, the light and shadow assembly 20 may further include a light collecting member 29, wherein the light collecting member 29 is located between the background light source 25 and the light transmitting plate 21 and is close to the background light source 25. Specifically, the light of the background light source 25 is generally scattered around, so that most of the light cannot pass through the second through hole 112, which affects the brightness of the background light shadow on the one hand, and the first light of the yellow light source 24 on the other hand. The light-gathering member 29 is configured to gather the light emitted by the background light source 25, so that most of the second light emitted by the background light source 25 is constrained to the predetermined track to pass through the second through hole 112, thereby not only increasing the brightness of the background light, but also avoiding interference with the first light emitted by the yellow light source 24.

Further, the light-gathering member 29 has a truncated cone-shaped inner cavity 290, and the backlight source 25 is disposed at one end of the inner cavity 290 near the top surface of the truncated cone, so that the light rays emitted by the backlight source 25 are reflected by the surface of the inner cavity 290 and then gathered together and then emitted through the magnifying lens 28 of the second through hole 112. Wherein, the light collecting member 29 is connected to the base 251 and accommodates the lamp 252.

With continued reference to fig. 2 to 5, the heat dissipation assembly 30 is fixed to a side of the second support plate 62 facing away from the first support plate 61, and is connected to the yellow light source 24 for dissipating heat from the yellow light source 24. It will be appreciated that the yellow light source 24 is a thermal source, and that the temperature of the yellow light source 24 may continue to rise after continued operation, causing damage to the yellow light source 24, and severe or even spontaneous combustion. The heat dissipation assembly 30 is arranged to maintain the temperature of the yellow light source 24 within a safe operating range, thereby improving the reliability and service life of the yellow light source 24.

Specifically, the heat dissipation assembly 30 may include a heat conduction member 31 and a heat dissipation member 32 disposed adjacent to the heat conduction member 31, wherein the heat dissipation member 32 is used for reducing the temperature of the heat conduction member 31. The yellow light source 24 is connected to the heat conducting member 31, so that heat generated by the operation of the yellow light source 24 can be transferred to the heat conducting member 31 and carried away by the heat dissipating member 32.

Referring to fig. 9 together, fig. 9 is a schematic perspective view of a heat conducting member of the heat dissipating assembly in the firefly atmosphere simulation device shown in fig. 4. In this embodiment, the heat conducting member 31 includes a main body 311 and a fin 312 connected to the main body 311, and the fin 312 is connected to the main body 311 to increase the heat dissipation area of the heat conducting member 31, so that the heat conducting member 31 still has a good heat dissipation effect even if the heat conducting member 31 is not adjacent to the heat dissipating member 32 or the heat dissipating member 32 does not work.

The body portion 311 may be provided with a mounting hole 3110, and the mounting hole 3110 is used for accommodating and fixing the yellow light source 24, so that the sidewall of the yellow light source 24 is fully contacted with the heat conducting member 31. Wherein, the body portion 311 is fixed on the surface of the second support plate 62 facing away from the first support plate 61, so that the heat dissipating assembly 30 is fixedly connected with the bracket 60.

In the present embodiment, the heat dissipation member 32 is fixed to the second support plate 62 and disposed adjacent to the heat conduction member 31, so that the heat dissipation member 32 can reduce the temperature of the heat conduction member 31.
