Description

Technical Field

[0001] The present invention relates to the technical field of stage lighting, and more particularly to a stage lamp with additional visual effects. Background Art

[0002] In the field of stage lighting technology, traditional stage lights create brilliant lighting effects by combining a main light source with effect components such as a pattern plate or color plate to project various light effects at the target location. When the main light source is turned off, the stage light itself will not have any decorative effect, and it looks relatively monotonous and cannot attract the audience's attention. Summary of the Invention

[0003] The object of the present invention is to overcome at least one of the above-mentioned defects in the prior art and provide a stage light with additional visual effects. Without increasing the volume of the stage light, an effect light source is set for the light-transmitting sheet, thereby adding an additional lighting effect without affecting the light path and light effect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a stage light with additional visual effects, comprising a main light source and a lamp tube, wherein the main light source is located at the bottom of the lamp tube, and is characterized in that it also includes an effect light source and a light-transmitting sheet located at the light outlet of the lamp tube; the effect light source and the main light source are independently controlled from each other, the light-transmitting sheet has a first surface and a second surface, and a first side and a second side respectively connecting the first surface and the second surface, at least a portion of the light emitted by the effect light source enters from the first side and is emitted from the second side.

[0005] At least a portion of the light emitted by the effect light source enters from the first side and is emitted from the second side, so that the second side is illuminated, thereby decorating the stage light itself. Compared with only being able to present the lighting effect in a projected manner at a target position, the effect presentation method of the stage light is increased, making the stage light itself more attractive. In addition, the effect light source is used alone to render the light-transmitting sheet, which is independent of the main light source, so that the effect light source can be independently controlled. When the main light source is turned off, the effect light source can be turned on alone to illuminate the second side of the light-transmitting sheet, which makes the effect more obvious and increases the decorative effect of the stage light itself.

[0006] Furthermore, at least one of the first surface and the second surface is frosted. The frosted surface treatment allows light emitted by the effect light source to pass through the first side edge and enter the interior of the light-transmitting sheet, where it is refracted and reflected, thereby illuminating the first surface and / or the second surface. This ensures that the light-transmitting sheet can fully utilize the light, reduces the light emitted from the first surface and / or the second surface, and increases the brightness of the second side edge.

[0007] Furthermore, the thickness of the light-transmitting sheet is greater than or equal to 15% of the width of the luminous surface of the effect light source. Utilization of the effect light source is maximized to ensure that the luminous flux of light emitted by the effect light source entering the light-transmitting sheet has sufficient brightness.

[0008] Furthermore, the thickness of the light-transmitting sheet ranges from 0.5 mm to 3 mm. This prevents the light path of the main light source from being blocked by the light-transmitting sheet, thereby causing a distinct dark area to appear in the projected light spot.

[0009] Furthermore, at least part of the light emitted by the effect light source enters the first side edge vertically, so that light loss is small when entering the first side edge, that is, light reflection is reduced, so that more light enters the first side edge.

[0010] Furthermore, the light-transmitting sheet is parallel to the optical path of the main light source to prevent the light-transmitting sheet from blocking the light emitted by the main light source and affecting the lighting effect. Since the light emitted by the main light source will pass through the light-transmitting sheet, if the light-transmitting sheet is an atomizing sheet or a color filter, the light effect of the light emitted by the main light source will be atomized or changed in color by the light-transmitting sheet, resulting in unnecessary lighting effects.

[0011] Furthermore, the light-transmitting sheets are arranged side by side or radially distributed around the center of the light path, so that the second side edges of the light-transmitting sheets can be arranged into corresponding shapes, which has a beautiful effect and is easy to fix.

[0012] Furthermore, the light-transmitting sheets are distributed side by side at the light outlet, and both ends of the light-transmitting sheets are connected to the lamp tube.

[0013] Furthermore, a central axis is provided in the lamp tube, and the central axis of the light-transmitting sheet is radially distributed. One end of the light-transmitting sheet is connected to the lamp tube, and the other end is connected to the central axis.

[0014] Furthermore, the first side is the side of the light-transmitting sheet close to the side wall of the lamp tube, and the second side is the side of the light-transmitting sheet away from the main light source. The second side is located on the side of the light-transmitting sheet away from the light source to ensure that the viewer can directly see the light emitted by the second side. The first side is close to the side wall of the lamp tube, so that the effect light source can be installed on the side wall of the lamp tube, which facilitates the installation of the effect light source.

[0015] Furthermore, the light-transmitting sheet is pivotally fixed and can switch between a first state and a second state. When the light-transmitting sheet is in the first state, the light-transmitting sheet is parallel to the optical path of the main light source. When the light-transmitting sheet is in the second state, at least part of the light emitted by the main light source enters from the first surface and is emitted from the second surface. The light-transmitting sheet can rotate around the rotation axis and can adjust its state according to different interpretation needs. When the light-transmitting sheet is in the first state, the light-transmitting sheet receives the light emitted by the effect light source to perform additional visual effects. When the light-transmitting sheet is in the second state, if the light-transmitting sheet is an atomizing sheet, the main light source can adjust the atomizing effect through the light-transmitting sheet. If it is a color sheet, the local color of the projected light spot can be changed.

[0016] Furthermore, the rotation axis of the light-transmitting sheet is perpendicular to the optical path of the main light source, which saves space occupied by the light-transmitting sheet in the direction of the optical path and facilitates the installation of the light-transmitting sheet.

[0017] Furthermore, the effect light source is located on the rotation axis of the light-transmitting sheet. During the rotation of the light-transmitting sheet, the light emitted by the effect light source can always enter the light-transmitting sheet, ensuring that the second side is continuously illuminated.

[0018] Furthermore, one end of the light-transmitting sheet is pivotally connected, and the effect light source is located at the other end of the light-transmitting sheet on the rotation axis of the light-transmitting sheet, so that the effect light source is arranged on the rotation axis of the light-transmitting sheet.

[0019] Furthermore, the effect light source is a multi-color LED. The effect light source has multiple colors, so that the light-transmitting sheet can achieve multiple color changes.

[0020] Furthermore, there are multiple effect light sources and multiple light-transmitting sheets, and each light-transmitting sheet corresponds to at least one effect light source, so that the light received by the light-transmitting sheet has sufficient brightness.

[0021] Furthermore, the plurality of effect light sources are independently controlled from each other or in groups. The color and on / off state of the multi-color LEDs are independently controlled from each other or in groups by software, thereby creating a possibility of combining multiple colors and lighting dynamics.

DETAILED DESCRIPTION

[0029] The accompanying drawings are for illustrative purposes only and are not to be construed as limiting the present invention. To better illustrate the following embodiments, some components in the accompanying drawings may be omitted, enlarged, or reduced in size, and do not represent actual product dimensions. Those skilled in the art will appreciate that some well-known structures and their descriptions may be omitted from the accompanying drawings.

[0030] like Figures 1 to 3 , which is a first embodiment of the present invention, provides a main light source 400 and a lamp tube 300, wherein the main light source 400 is located at the bottom of the lamp tube 300, and is characterized in that it also includes an effect light source 200 and a light-transmitting sheet 100 located at the light outlet of the lamp tube 300; the effect light source 200 and the main light source 400 are independently controlled from each other, the light-transmitting sheet 100 has a first surface and a second surface, and a first side 110 and a second side 120 respectively connecting the first surface and the second surface, at least a part of the light emitted by the effect light source 200 enters from the first side 110 and is emitted from the second side 120.

[0031] At least a portion of the light emitted by the effect light source 200 enters from the first side 110 and is emitted from the second side 120, so that the second side 120 is illuminated, thereby decorating the stage light itself. Compared with the lighting effect that can only be displayed by projecting at the target position, the effect presentation method of the stage light is increased, making the stage light itself more attractive. In addition, the effect light source 200 is used alone to render the light-transmitting sheet 100, which is independent of the main light source 400. Therefore, the effect light source 200 can be controlled separately. When the main light source 400 is turned off, the effect light source 200 can be turned on separately to light up the second side 120 of the light-transmitting sheet 100, which makes the effect more obvious and increases the decorative effect of the stage light itself.

[0032] like Figure 1 As shown, in a preferred embodiment of the present invention, the stage light is sequentially provided with the main light source 400, the light guide 530, the focusing lens 500, the light-transmitting sheet 100 and the light-emitting mirror 510 along the emission direction of the light source. A light shielding plate 520 is further provided between the main light source 400 and the focusing lens 500. The light guide 530 is spaced apart in the grid of the light shielding plate 520 to avoid cross-light.

[0033] In the first embodiment of the present invention, at least one of the first and second surfaces is frosted. This frosting allows light emitted by the effect light source 200 to pass through the first side edge 110 and enter the interior of the light-transmitting sheet 100, where it is refracted and reflected, thereby illuminating the first and / or second surfaces. This ensures that the light-transmitting sheet 100 can fully utilize light, reduces light emitted from the first and / or second surfaces, and increases the brightness of the second side edge 120. Both the first and second surfaces are frosted.

[0034] In a preferred embodiment of the present invention, the thickness of the light-transmitting sheet 100 is greater than or equal to 15% of the width of the light-emitting surface of the effect light source 200. This maximizes the utilization of the effect light source 200 and ensures that the luminous flux of the light emitted by the effect light source 200 enters the light-transmitting sheet 100, thereby providing the light-transmitting sheet 100 with sufficient brightness.

[0035] In a preferred embodiment of the present invention, the thickness of the light-transmitting sheet 100 ranges from 0.5 mm to 3 mm. This prevents the light path of the main light source 400 from being blocked by the light-transmitting sheet 100, thereby causing a distinct dark area in the projected light spot. Preferably, the thickness of the light-transmitting sheet 100 is 1.2 mm.

[0036] like Figure 2As shown, in a preferred embodiment of the present invention, at least a portion of the light emitted by the effect light source 200 enters the first side edge 110 perpendicularly. This minimizes light loss when entering the first side edge 110, i.e., reduces light reflection, allowing more light to enter the first side edge 110. In this embodiment, the effect light source 200 faces the first side edge 110, allowing as much light as possible to enter the first side edge 110 perpendicularly.

[0037] like Figure 1 As shown, in a preferred embodiment of the present invention, the light-transmitting sheet 100 is parallel to the optical path of the main light source 400. This prevents the light-transmitting sheet 100 from blocking the light emitted by the main light source 400 and affecting the lighting effect. Since the light emitted by the main light source 400 passes through the light-transmitting sheet 100, if the light-transmitting sheet 100 is an atomizing sheet or a color filter, the light emitted by the main light source 400 will be atomized or changed in color by the light-transmitting sheet 100, resulting in unnecessary lighting effects.

[0038] In a preferred embodiment of the present invention, the light-transmitting sheets 100 are arranged side by side or radially distributed around the center of the optical path. This allows the second side edges 120 of the light-transmitting sheets 100 to be arranged in corresponding shapes, creating a beautiful effect and facilitating securement. In other embodiments, the light-transmitting sheets 100 can also be arranged in other shapes, such as a five-pointed star, triangle, or plum blossom, to create a richer effect.

[0039] like Figure 1 、 Figure 3 As shown, the lamp tube 300 is provided with a central axis 600, and the light-transmitting sheets 100 are radially distributed around the central axis 600. One end of the light-transmitting sheets 100 is connected to the lamp tube 300, and the other end is connected to the central axis 600. This arrangement is preferred when the lamp tube 300 is circular. Optionally, the central axis 600 is coaxial with the lamp tube 300, and the central axis 600 can be hollow or solid.

[0040] Optionally, the light-transmitting sheets 100 are arranged side by side at the light outlet, and both ends of the light-transmitting sheets 100 are connected to the lamp tube 300. No additional fixing elements are required, and this method is preferred when the lamp tube 300 is square.

[0041] In a preferred embodiment of the present invention, the first side 110 is the side of the light-transmitting sheet 100 close to the sidewall of the lamp tube 300, and the second side 120 is the side of the light-transmitting sheet 100 away from the main light source 400. The second side 120 is located on the side of the light-transmitting sheet 100 away from the light source to ensure that the viewer can directly see the light emitted by the second side 120. The first side 110 is close to the sidewall of the lamp tube 300, so the effect light source 200 can be installed on the sidewall of the lamp tube 300, facilitating the installation of the effect light source 200. In other embodiments, the first side 110 and the second side 120 can also be located at other positions on the light-transmitting sheet 100.

[0042] like Figure 3 As shown, in a preferred embodiment of the present invention, the light-transmitting sheet 100 is pivotally fixed and can be switched between a first state and a second state. When the light-transmitting sheet 100 is in the first state, the light-transmitting sheet 100 is parallel to the optical path of the main light source 400. When the light-transmitting sheet 100 is in the second state, at least part of the light emitted by the main light source 400 enters from the first surface and is emitted from the second surface. The light-transmitting sheet 100 can rotate around the rotation axis and can be adjusted to meet different interpretation needs. When the light-transmitting sheet 100 is in the first state, the light-transmitting sheet 100 receives the light emitted by the effect light source 200 to perform additional visual effects. When the light-transmitting sheet 100 is in the second state, if the light-transmitting sheet 100 is an atomizing sheet, the main light source 400 can adjust the atomization effect through the light-transmitting sheet 100. If it is a color filter, the local color of the projected light spot can be changed.

[0043] In this embodiment, the light-transmitting sheet 100 is radially distributed around the central axis of the optical path. A central axis 600 is provided within the lamp tube 300. One end of the light-transmitting sheet 100 is connected to the central axis 600 and the other end is connected to a rotating shaft 700. A through hole is provided in the side wall of the lamp tube 300. The rotating shaft 700 extends through the through hole in the side wall of the lamp tube 300 and is fixedly connected to a lever 800. The lever 800 is slidably connected to the moving block 900. The moving block 900 is pivotally connected to a pivot shaft 910. The pivot shaft 910 is driven by a driving mechanism to move circumferentially along the lamp tube 300. Therefore, the pivot shaft 910 drives the moving block 900 to move. Since the lever 800 is slidably connected to the moving block 900, both the moving block 900 and the lever 800 rotate. In turn, the lever 800 drives the rotating shaft 700 to rotate, thereby rotating the light-transmitting sheet 100.

[0044] Optionally, the rotating shaft 700 has an expansion portion 130 near one end of the light-transmitting sheet 100, and an elastic member 140 is sleeved on the rotating shaft 700, with one end abutting against the expansion portion 130 and the other end abutting against the side wall of the lamp tube 300, thereby achieving the installation and fixation of the light-transmitting sheet 100. By compressing the elastic member 140, an exit space can be provided for the installation of the other end of the light-transmitting sheet 100.

[0045] In a preferred embodiment of the present invention, the rotation axis of the light-transmitting sheet 100 is perpendicular to the optical path of the main light source 400. This saves space occupied by the light-transmitting sheet 100 in the optical path direction and facilitates installation of the light-transmitting sheet 100.

[0046] In a preferred embodiment of the present invention, the effect light source 200 is a multi-color LED. The effect light source 200 has multiple colors, so that the light-transmitting sheet 100 can achieve multiple color changes. The effect light source 200 has three colors: red, green, and blue.

[0047] like Figures 1 to 3 As shown, in a preferred embodiment of the present invention, there are multiple effect light sources 200 and multiple light-transmitting sheets 100, with each light-transmitting sheet 100 corresponding to at least one effect light source 200. This ensures that the light received by the light-transmitting sheet 100 has sufficient brightness. In this embodiment, there are 16 light-transmitting sheets 100 and 16 effect light sources 200, with each light-transmitting sheet 100 corresponding to one effect light source 200.

[0048] In a preferred embodiment of the present invention, the plurality of effect light sources 200 are independently controlled or grouped. The effect light sources 200 are independently controlled by software or grouped to independently control the color and on / off state of the multi-color LEDs, thereby creating a variety of color and lighting dynamic combinations.

[0049] Optionally, among the 16 effect light sources 200 , the effect light sources 200 corresponding to one light-transmitting sheet 100 form a group, and the effect light sources 200 are divided into 16 groups. The 16 groups of effect light sources 200 are independently controlled through software.

[0050] Optionally, among the 16 effect light sources 200, the effect light sources 200 corresponding to 4 of the light-transmitting sheets 100 are grouped together, so that the effect light sources 200 corresponding to the 16 light-transmitting sheets 100 are divided into 4 groups, and the 4 groups of effect light sources 200 are independently controlled by software.

[0051] Figures 4 and 5, which is a second embodiment of the present invention, the effect light source 200 is located on the rotation axis of the light-transmitting sheet 100. During the rotation of the light-transmitting sheet 100, the light emitted by the effect light source 200 can always enter the light-transmitting sheet 100, ensuring that the second side 120 is continuously illuminated.

[0052] In the second embodiment, one end of the light-transmitting sheet 100 is pivoted, and the effect light source 200 is located at the other end of the light-transmitting sheet 100 on the rotation axis of the light-transmitting sheet 100 . In this embodiment, an axial column 610 is set inside the central axis 600, and the axial column 610 is coaxially arranged with the central axis 600; the 16 effect light sources 200 are evenly distributed on the axial column 610; the central axis 600 is provided with a mounting hole 620, and the translucent sheet 100 is pivotally connected to the lamp tube 300 at one end close to the lamp tube 300, and the other end is connected to the mounting hole 620, and is respectively aligned with one of the effect light sources 200 set on the axial column 610, and a central axis cover 630 is covered on the central axis 600, and cooperates with the mounting hole 620 to limit the translucent sheet 100, and the central axis cover 630 can be connected to the central axis 600 by screws.

[0053] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the technical solutions of the present invention, and are not intended to limit the specific implementation methods of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of the present invention shall be included within the scope of protection of the claims of the present invention.
