However, most of the current lamp and projection combination products are simply spliced together, and the two do not interfere with each other and run independently.

[0053] Therefore, it is particularly important to design a machine that uses projection light for illumination.

[0054] Please refer to FIGS. 1-9, the present embodiment provides a projection device 100 with lamp effect, which can effectively improve the above-mentioned technical problems, can use projection light for illumination, realize multiple functions, and improve the use feeling.

[0055] Please refer to FIGS. 1-9, the present embodiment provides a projection device 100 with lamp effect, which can effectively improve the above-mentioned technical problems, can use projection light for illumination, realize multiple functions, and improve the use feeling.

[0056] Specifically, the first shell 11 and the second base 12 are arranged opposite to each other along the vertical direction, and the first shell 11 is located above the second base 12. The first shell 11 and the second base 12 can approach or move away from each other along the vertical direction. The bottom of the first shell 11 is provided with an opening, and the position of the lens of the projection host 20 corresponds to the position of the opening, so that the light emitted by the projection host 20 after starting can be emitted to the reflection plate 30 on the second base 12 through the opening, thereby generating a light effect.

[0057] In the present embodiment, the first shell 11 and the second base 12 are both cylindrical cavity structures, and the reflection plate 30 is fixed to the top edge of the second base 12.

[0058] In other embodiments, the projection host 20 can also be installed on the second base 12, and the reflection plate 30 can be installed on the first shell 11. The light emitted by the projection host 20 after starting is upwardly irradiated, thereby being emitted to the reflection plate 30.

[0059] In the embodiment, the first shell 11 and the second base 12 are slidably connected, and the first shell 11 and the second base 12 slide to a preset distance in a direction away from each other, so that the light emitted by the projection host 20. Wherein, after the first shell 11 and the second base 12 slide to a preset distance in a direction away from each other, the light generated by the projection host 20 can produce a light effect after being reflected by the reflecting plate 30. The area where the light effect is produced is the interval area between the first shell 11 and the second base 12. Wherein, through many experiments, it is found that by adjusting the distance between the first shell 11 and the second base 12, the brightness of the light effect can be adjusted. Under the same lighting conditions, the greater the distance between the first shell 11 and the second base 12, the more the light escapes, and the lower the brightness of the light effect.

[0060] In the embodiment, the preset distance is less than 20mm. Specifically, the preset distance is 11mm. In other embodiments, the preset distance can also be 13mm, 10mm or 16mm, etc., which is not limited here.

[0061] In the embodiment, in order to form a more uniform light belt when the projection host 20 is illuminated, and in order to better utilize the light reflected by the reflecting plate 30, the projection device with light effect provided by the embodiment further comprises a lampshade 40, which is detachably arranged between the first shell 11 and the second base 12. The lampshade 40 is used to cover the interval area between the first shell 11 and the second base 12 when the first shell 11 and the second base 12 move to a preset distance in a direction away from each other. Wherein, the light reflected by the first side 31 of the reflecting plate 30 can be reflected again by the inner wall of the lampshade 40, so that the generated light effect is more uniform.

[0062] In the embodiment, the lampshade 40 is a C-shaped structure, and the lampshade 40 has a certain deformation force. After the first shell 11 and the second base 12 move to a preset distance, the lampshade 40 can be directly connected to the outside of the first shell 11 and the second base 12, which is convenient for installation and disassembly.

[0063] Please refer to FIG. 4-6, it also needs to be explained that the projection device with light effect 100 further comprises a sliding mechanism, the sliding mechanism comprises a guide rail and a sliding piece, the guide rail and the second base 12 are connected, the sliding piece and the guide rail are slidably connected, and the first shell 11 and the sliding piece are connected. Wherein, the sliding piece can slide along the guide rail, so that the first shell 11 and the second base 12 are close to or away from each other.

[0064] Specifically, the sliding mechanism 50 comprises a guide rail 51 and a sliding piece 52, the sliding piece 52 is slidingly connected to the guide rail 51, the sliding piece 52 is provided with a limiting part 521, the guide rail 51 is provided with a stop part matched with the limiting part 521, when the sliding mechanism 50 is in linear sliding adjustment, the sliding stroke can be restricted or the sliding position can be positioned by the cooperation of the limiting part 521 and the stop part.

[0065] Preferably, the limiting part 521 or the stop part is in an elastic arch structure, which can be elastically deformed to release the limiting when the limiting hovering is achieved, so that the operation of sliding the sliding piece 52 is more convenient. The limiting part 521 is a detachable part connected to the sliding piece 52, the sliding piece 52 is provided with a hole, the limiting part 521 is provided with a buckle 5211 to enable the limiting part 521 to be clamped and connected in the hole, which is convenient to assemble and disassemble and easy to maintain and replace. Preferably, the limiting part 521 is made of wear-resistant self-lubricating material, which has good wear resistance, long service life, low friction coefficient, reduces the required force for sliding adjustment, and makes the operation more convenient and improves the convenience of use. More preferably, the hole edge of the sliding piece 52 is extended to be provided with a stop edge 501, the limiting part 521 abuts against the stop edge 501 when clamped into the hole, the stop edge 501 limits the position of the limiting part 521 to keep it accurate and stable. Since the limiting part 521 is in an elastic arch structure, in order not to hinder the elastic deformation of the limiting part 521, buckles 5211 are respectively arranged at both ends of the arch structure, which not only ensures that the limiting part 521 can be reliably clamped in the hole, but also ensures that the limiting part 521 can be effectively elastically deformed to release the limiting hovering between the sliding piece 52 and the guide rail 51. Further, the buckles 5211 are respectively arranged on both sides of the limiting part 521 in a direction perpendicular to the line connecting the two ends of the arch structure, that is, the buckles 5211 are symmetrically arranged on the end portions of the arch structure with the line connecting the two ends of the arch structure as the symmetry line, which further improves the clamping stability. Similarly, the stop part can also have a similar structure to the limiting part 521 for easy maintenance and replacement.

[0066] Furthermore, the projection device 100 with light effect further comprises a rotating mechanism, the first shell 11 and the sliding piece are connected through the rotating mechanism, and the first shell 11 is used to rotate relative to the second base body 12 through the rotating mechanism.

[0067] In the embodiment, the rotating mechanism can drive the first shell 11 to rotate relative to the second base body 12, when the first shell 11 is rotated to a first angle, the projection host 20 is in an illumination state, and when the first shell 11 is rotated to a second angle, the projection host 20 is in a projection state.

[0068] In the embodiment, the first angle is less than 30°, when the first shell 11 rotates within 30°, the projection host 20 does not project, the light emitted by the projection host 20 is only used for illumination.

[0069] In the embodiment, the second angle is 30°-360°, that is, when the first shell 11 rotates more than 30°, the projection host 20 projects normally.

[0070] As shown in the relative position of FIG. 2, the first shell 11 rotates the projection host 20 from bottom to top, which can rotate clockwise or counterclockwise, when the rotation angle of the first shell 11 is greater than 30°, the light generated by the projection host 20 will not be projected on the reflecting plate 30, and the light effect will not be generated by reflection, so that the projection host 20 projects normally.

[0071] Please refer to FIG. 2 and FIG. 3, it needs to be explained that the reflecting plate 30 includes opposite first side 31 and second side ， The first side 31 is close to the projection host 20, and the second side is away from the projection host 20, as shown in the relative position of FIG. 3, the upper side of the reflecting plate 30 is the first side 31, and the lower side of the reflecting plate 30 is the second side.

[0072] Please refer to FIG. 7 and FIG. 9, after the projection host 20 is powered on, the light emitted by the light source of the projection host 20 is shot to the reflecting plate 30, and the propagation path of the light will have three different states, which will be described in detail below.

[0073] Please refer to FIG. 7, when the light emitted by the projection host 20 reaches the first side 31, the light is reflected back to the air by the first side 31. Among them, part of the light reflected back to the air can be shot to the bottom of the first shell 11 for re-reflection, and part of the light reflected back to the air can be shot to the inner wall of the lampshade 40 for re-reflection.

[0074] In the embodiment, the bottom of the first shell 11 can adopt the same material and structure as the reflecting plate 30, so as to improve the light effect.

[0075] Please refer to FIG. 8, when the light emitted by the projection host 20 reaches the first side 31, part of the light is reflected back to the air by the first side 31, and another part of the light is refracted to the inside of the reflecting plate 30 by the first side 31, the light entering the inside of the reflecting plate 30 is shot to the second side, and the light is reflected back to the first side 31 by the second side again.

[0076] Specifically, the light rays reflected back to the first side 31 from the second side are partially transmitted out of the first side 31, and the other part of the light rays are reflected back to the second side again and circulate.

[0077] Specifically, the second side of the reflection plate 30 can be a total reflection structure.

[0078] Please refer to FIG. 9, when the light rays emitted by the projection host 20 reach the first side 31, part of the light rays are reflected back to the air by the first side 31, and the other part of the light rays are refracted into the interior of the reflection plate 30 by the first side 31. The light rays entering the interior of the reflection plate 30 are directed to the second side, and part of the light rays are transmitted out of the second side. Thus, a light-transmitting effect is formed, and the other part of the light rays entering the interior of the reflection plate 30 are reflected back to the first side 31 again by the second side.

[0079] It needs to be explained that, in order to make the light effect generated by the projection host 20 stronger, the number of light rays transmitted out of the reflection plate 30 needs to be reduced. Therefore, the reflection plate 30 is made of a semi-transparent material, and the transmittance of the semi-transparent material is preferably between 0.4% and 2.2%.

[0080] It also needs to be explained that the first side 31 and / or the second side are rough surfaces, so that the light rays directed to the first side 31 and / or the second side form diffuse reflection. In this embodiment, the first side 31 of the reflection plate 30 is a rough surface, wherein the first side 31 of the reflection plate 30 is subjected to a sunken line treatment, so that the surface of the first side 31 is a concave-convex structure, thereby making the light rays directed to the first side 31 produce diffuse reflection.

[0081] In other embodiments, the second side of the reflection plate 30 is a rough surface, or both the first side 31 and the second side of the reflection plate 30 are rough surfaces, which are not specifically limited here.

[0082] Further, the projection device 100 with light effect further comprises a sound and a controller, and the sound and / or the controller are installed in the second base body 12. In other embodiments, the sound and / or the controller can also be installed in the first shell 11, which is not specifically limited here.

[0083] Further, the second base body 12 is made of a semi-transparent material or a light-transmitting material, so that the light rays transmitted out of the second side are used to be transmitted out of the second base body 12.

[0084] In order to improve the overall uniform light effect, the light rays emitted by the projection host 20 form a circular area on the reflection plate 30. Specifically, the visual material projected by the projection host can be changed to a circular shape, and the uniform light effect of the circular structure is better. The shape of the light effect reflected is the same as the shape of the projection, and the visual effect is better.

[0085] In other embodiments, the reflective plate 30 is provided with a fluorescent layer on a side surface close to the projection host 20 or is provided with fluorescent particles inside. Thus, the light emitted by the projection host 20 can excite the fluorescent powder to generate a lamp effect after being incident on the first side surface 31 of the reflective plate 30.

[0086] In other embodiments, the reflective plate 30 is a total reflection structure or is a light diffusion plate.

[0087] The embodiments of the present application also provide a control method of the projection device 100 with a lamp effect, for controlling the projection device 100 with a lamp effect, and the control method comprises the following steps.

[0088] S1: driving the rotating mechanism to rotate the first shell 11 relative to the second base 12, and the first shell 11 slides to a preset distance away from the second base 12 under the action of the sliding mechanism.

[0089] Specifically, the rotation angle of the first shell 11 is detected by a gyroscope, and the first shell 11 slides 11 mm upward relative to the second base 12.

[0090] S2: when the first shell 11 rotates to a first angle, the light generated by the projection host 20 is incident on the reflective plate 30 to generate a light effect.

[0091] Specifically, when the rotation angle of the first shell 11 is within 30°, the light generated by the projection host 20 is incident on the first side surface 31 of the reflective plate 30 to generate a diffuse reflection, thereby forming a light effect.

[0092] S3: when the first shell 11 rotates to a second angle, the projection host 20 starts to project.

[0093] When the rotation angle of the first shell 11 is within 30°-360°, the light generated by the projection host 20 is incident on the reflective plate 30, and the controller controls the projection host 20 to normally project.

[0094] Specifically, the controller controls the color and brightness of the light generated by the projection host 20 according to a sound control, a key or a remote control instruction, and the color and brightness of the light can also be automatically adjusted following the audio signal of the sound, so as to achieve the effect that the light follows the sound. In the present embodiment, the color of the light source of the projection host 20 includes red light, green light and blue light, and the controller controls the color and brightness of the light effect of the projection host 20 by controlling the color ratio between the red light, the green light and the blue light, thereby effectively controlling the entire light.
