DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Embodiment 1: Figures 1 to 3 The figure is only one of the embodiments of the present invention, a multifunctional stage lighting device, comprising a fixed plate 1, a support column 3 for supporting the fixed plate 1, and a movable plate 2 connected to the fixed plate 1 through a connecting portion 4, wherein the connecting portion 4 comprises a first plate body 41 connected to the fixed plate 1, a second plate body 42 connected to the movable plate 2, and a connecting column 43 for connecting the first plate body 41 and the second plate body 42, the second plate body 42 is a light-transmitting member, the connecting column 43 comprises a first beam 431 connected to the first plate body 41, a second beam 432 connected to the second plate body 42, and a connecting beam 433 for connecting the first beam 431 and the second beam 432, the length of the second beam 432 is not less than the length of the first beam 431, an LED lamp 411 is arranged on the side of the first plate body 41 away from the first beam 431, the movable plate 2 is a magnetic member, the fixed plate 1 is an electromagnetic member, and a smoke outlet 31 is arranged on the support column 3.

[0027] In the present invention, the fixed plate 1 is fixedly connected to the supporting column 3, the movable plate 2 is movably connected to the fixed plate 1, and an LED lamp 411 is arranged on the first plate body 41 below the fixed plate 1. The movable plate 2 rotates around the connecting column 32 to the second plate body 42 to block the front of the first plate body 41, thereby blocking the light emitted by the LED lamp 411 and blocking the smoke ejected from the smoke outlet 31 from spraying in front of the LED lamp 411, so as to adjust the light intensity and the influence of smoke on the light.

[0028] First, the fixed plate 1 and the movable plate 2 are connected. The first plate body 41 below the fixed plate 1 is connected to the second plate body 42 above the movable plate 1 through a connecting column 42. The connecting column 43 includes a first crossbeam 431 connected to the first plate body 41, a second crossbeam 432 connected to the second plate body 42, and a connecting beam 433 for connecting the first crossbeam 431 and the second crossbeam 432. The first crossbeam 431 rotates around the connection with the first plate body 41, and the rotation axis of the first crossbeam 431 is perpendicular to the connecting beam 433. Similarly, the second crossbeam 432 rotates around the connection with the second plate body 42, and the rotation axis of the second crossbeam 432 is perpendicular to the connecting beam 433. In this way, both the connecting beam 433 and the movable plate 2 can rotate around the rotation axis of the first crossbeam 431.

[0029] Then comes the rotation of the movable plate 2. The movable plate 2 is a magnetic part, and the fixed plate 1 is an electromagnetic part that generates magnetism when powered. The length of the second beam 432 is not less than the length of the first beam 431. When the fixed plate 1 is charged, a magnetic field is generated, preferably an attraction force is generated opposite to the magnetic pole of the movable plate 2 as a magnetic part, so that the movable plate 2 rotates upward and rotates in the direction of the fixed plate 1. At this time, the connecting beam 433 rotates around the axis of the first beam 431. It is best to have multiple connecting columns 43, so that multiple connecting beams 433 on the movable plate 2 rotate around the axis of the first beam 431, and at the same time, the connecting beam 433 rotates around the axis of the second beam 432 to ensure that the movable plate 2 and the fixed plate 1 rise and fall in parallel, and the length of the second beam 432 is not less than the length of the first beam 431. In this way, when the movable plate 2 is closest to the fixed plate 1, the second plate body 42 is located between the movable plate 2 and the fixed plate 1, and the second plate body 42 is just located on the side of the first plate body 41 away from the first beam 431.

[0030] When the fixed plate 1 is not powered, the magnetism of the fixed plate 1 disappears, and the movable plate 2 descends under gravity. If it is to facilitate the movable plate 2 to fall faster, the charging direction of the fixed plate 1 can be changed at this time, so that the magnetism of the fixed plate 1 is the same as that of the movable plate 2, generating a repulsive force to push the movable plate 2 to fall.

[0031] Finally, the light, shadow and smoke are adjusted when the movable plate 2 rotates.

[0032] In terms of light and shadow, an LED lamp 411 is provided on a side of the first plate body 41 away from the first cross beam 431. When the movable plate 2 is not raised, the LED lamp 411 directly irradiates outward. When the movable plate 2 is raised, the second plate body 42 is just located on the side of the first plate body 41 away from the first cross beam 431, so the second plate body 42 just blocks the light of the LED lamp 411. Here, the second plate body 42 is a light-transmitting member, which can be a color-gradient object, or a simple multi-layer color object, that is, the color changes from dark to light or from light to dark from bottom to top. In this way, when the movable plate 2 is raised, when the second plate body 42 blocks the light of the LED lamp 411 from bottom to top, the light of the LED lamp 411 changes from bright to dark, or from dark to bright, thereby changing the light and shadow.

[0033] Regarding the smoke, a smoke outlet 31 is provided on the support column 3. It should be noted that the smoke outlet 31 is provided at the connection between the support column 3 and the fixed plate 1. When the movable plate 2 is not raised, the smoke ejected from the smoke outlet 31 can be ejected along the lower side of the fixed plate 1 and combined with the light of the LED lamp 411. After the movable plate 2 is raised, the smoke is blocked by the movable plate 2 and can only flow out from the bottom of the movable plate 2 or be blocked by the movable plate 2 and return. At this time, the smoke is separated from the light.

[0034] The multifunctional stage light and shadow device of the present invention has a simple structure, and the light and smoke are arranged in one body, and the light intensity and the smoke spraying range can be controlled, and the light and shadow effect is good.

[0035] Embodiment 2, still as Figures 1 to 3 The figure is only one embodiment of the present invention. In order to make the light and shadow effect of the multifunctional stage light and shadow device of the present invention better and more stable, the present invention also has the following designs:

[0036] First, the length of the second crossbeam 432 is not less than the sum of the length of the first crossbeam 431 and the width of the first plate 41 , to ensure that the second plate 42 will not collide with the first plate 41 after the movable plate 2 is activated, and the second plate 42 must be located in front of the first plate 41 .

[0037] Preferably, when the second plate 42 is raised, the side of the second plate 42 close to the first plate 41 just contacts the LED lamp 411, so that the second plate 42 can protect the LED lamp 411 from dust after it is raised.

[0038] Then, the number of the first plate body 41 is at least one, and the distance between two adjacent first plate bodies 41 is not less than the width of the connecting beam 433. Then, after the second plate body 42 is raised, the connecting beam 433 is just located between the two first plate bodies 41, so that the connecting beam 433 is not stuck on the lower surface of the first plate body 41 and cannot rotate.

[0039] Similarly, the distance between the first cross beam 431 and the side of the first plate body 41 is not greater than the length of the connecting beam 433. It should be noted that the distance between the first cross beam 431 and the two side edges of the first plate body 41 is not greater than the length of the connecting beam 433, so that the connecting beam 433 will not be stuck on the lower surface of the first plate body 41 and cannot rotate.

[0040] Finally, the fixing plate 1 is connected to the support column 3 via a support pad 11 , and a connecting bolt 12 connected to the support column 3 is provided on the support pad 11 . The number of the connecting bolt 12 is at least one, and the connection is more stable.

[0041] It is also necessary to ensure that the fixed plate 1 is vertically arranged with respect to the support column 3 and the thickness of the support pad 11 is not less than the length of the connecting beam 433, so that the movable plate 2 can be rotated and lifted from the two sides of the first plate body 41 without hitting the support column 3 when being lifted or lowered.

[0042] The multifunctional stage light and shadow device of the present invention has a simple structure, and the light and smoke are arranged in one body, and the light intensity and the smoke spraying range can be controlled, and the light and shadow effect is good.

[0043] The present invention is not limited to the above specific implementations, and the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made to the above implementations based on the technical essence of the present invention shall be included in the protection scope of the present invention.
