In addition, part of the light will be emitted from the gap of the lamp housing, forming a light leakage phenomenon, which seriously affects the use effect of the stage light.

DETAILED DESCRIPTION

[0025] Embodiment 1

[0026] Combination Figure 1 A stage light fixture for preventing cross-talk, comprising a light source assembly 2 containing multiple light sources arranged in sequence along a light path, an anti-cross-talk assembly 3 for preventing the light emitted by the multiple light sources in the light source assembly 2 from affecting each other, and a light-emitting lens assembly 1, and the anti-cross-talk assembly 3 is elastically plugged and connected with the light-emitting lens assembly 1 in the light-emitting direction. The utility model proposes that the anti-cross-talk assembly 3 and the light-emitting lens assembly 1 are provided with a convex structure or a concave structure that cooperate with each other. Specifically, this plug-in structure enables the anti-cross-talk assembly 3 and the light-emitting lens assembly 1 to be tightly combined together. Figure 2 As shown, an elastic telescopic member 33 is provided between the lens cover 11 and the anti-cross-light cover 31, among which the most common is a spring. By changing the state of the elastic telescopic member 33, the position of the anti-cross-light component 3 relative to the light-emitting lens assembly 1 is precisely controlled, thereby realizing an elastic plug-in connection between the anti-cross-light component 3 and the light-emitting lens assembly 1. The beneficial effect of this embodiment is that the mutual plug-in structure of the anti-cross-light component 3 and the light-emitting lens assembly 1 effectively reduces the leakage and crosstalk of light during the transmission process. The elastic plug-in connection between the light-emitting lens assembly 1 and the anti-cross-light component 3 not only has the advantages of quick installation and disassembly, but also saves space.

[0027] As a new implementation method, combined with Figure 1 The light-emitting lens assembly 1 comprises a lens cover 11, a fixing plate 12 for fixing the lens cover 11, and a plurality of lenses 13 mounted on the upper part of the lens cover 11; a plurality of insert edges 111 extending toward the light source are provided at the lower part of the lens cover 11. Figure 3 and Figure 4As shown, the lens cover 11 is located above the anti-cross-light assembly 3, and three mounting holes 115 connected to the fixing plate 12 are provided on the outer side of the lens cover 11, and three mounting holes 2 116 are provided at the light-entering end of the lens cover 11; the lens 13 is installed on the upper part of the lens cover 11, and the outer circumference 113 of the lens cover is higher than the lens 13; the lower part of the lens cover 11 is provided with a plurality of insert edges 111, and the insert edges 111 are rectangular flat plates extending toward the light source. The beneficial effect of this embodiment is that the insert edge 111 design of the lens cover not only enhances the tightness and stability of the connection between the anti-cross-light assembly 3 and the lens cover 11, but also effectively prevents the relative movement or offset that may occur between the two during use. The design that the outer circumference 113 of the lens cover is higher than the lens 13 prevents light from leaking out from the edge or gap of the lens 13.

[0028] As a new implementation method, combined with Figure 1 , Figure 2 and Figure 5 The anti-cross-light component 3 includes an anti-cross-light cover 31, an elastic telescopic member 33 and a limit plate 32. The anti-cross-light cover 31 is provided with a slot 311 adapted to the insert edge 111. The anti-cross-light cover 31 is located between the lens cover 11 and the light source component 2. The anti-cross-light cover 31 is provided with a mounting hole 314 for accommodating the elastic telescopic member 33. The distribution of the mounting hole 314 is as follows: Figure 5 As shown; the elastic telescopic member 33 is located in the mounting hole 314, between the lens cover 11 and the anti-cross-light cover 31. The limit plate 32 is a circular ring structure, located on the outside of the anti-cross-light cover 31. The anti-cross-light cover 31 is also provided with a plurality of slots 311, and the structure of the slots 311 is adapted to the structure of the insert edge 111 of the lens cover 11. The beneficial effect of this embodiment is that the design of the slots 311 on the anti-cross-light cover 31 can achieve a stable elastic plug-in connection, and this structure provides the anti-cross-light cover 3 with space to move forward and backward along the light path direction.

[0029] As a new implementation method, combined with Figure 2 One end of the elastic telescopic member 33 abuts against the mounting seat 114 of the lens cover 11, and the other end abuts against the mounting hole 314 of the anti-light crosstalk cover 31. The elastic telescopic member 33 generally refers to a spring. The anti-light crosstalk cover 31 and the lens cover 11 form an elastic plug-in connection through the elastic telescopic member 33. When the elastic telescopic member 33 changes from a compressed state to a natural state, the anti-light crosstalk cover 31 can automatically reset. The beneficial effect of this embodiment is that the design of this elastic connection can flexibly change the position of the anti-light crosstalk cover 31.

[0030] As a new implementation method, combined with Figure 1 and Figure 2The inner diameter of the lens cover 11 is larger than the outer diameter of the anti-cross-light cover 31, so that when the lens cover 11 and the anti-cross-light cover 31 are plugged together, the anti-cross-light cover 31 can be located inside the lens cover 11. Compared with the embodiment in which the outer diameter of the lens cover 11 is smaller than the inner diameter of the anti-cross-light cover 31, the beneficial effect of this embodiment is that the anti-cross-light cover 31 is located inside the lens cover 11, and the plug-in structure of the lens cover 11 and the anti-cross-light cover 31 can be simplified.

[0031] As a new implementation method, combined with Figure 1 and Figure 2 , the limit plate 32 is fixed to the lens cover 11, and the limit plate 32 is used to limit the maximum stroke position of the anti-light-cross-talk cover 31. The limit plate 32 is a circular ring structure, located on the outside of the anti-light-cross-talk cover 31, and connected to the second mounting hole 116 of the lens cover 11. Since the limit plate 32 limits the maximum stroke of the anti-light-cross-talk cover 31, the anti-light-cross-talk cover 31 and the lens cover 11 move in opposite directions. The beneficial effect of this embodiment is that the limit plate 32 is connected to the lens cover 11, so that the limit plate 32 can move or be fixed together with the lens cover 11. By setting the limit plate 32, it is ensured that the anti-light-cross-talk cover 31 can maintain a stable elastic plug-in connection state with the lens cover 11 when reaching the maximum stroke position, which can effectively prevent the anti-light-cross-talk cover 31 and the lens cover 11 from accidentally separating during use.

[0032] As a new implementation method, combined with Figure 1 , Figure 3 and Figure 4 The lens cover 11 is also provided with a plurality of lens mounting holes 112 distributed in a honeycomb structure, and the insert edge 111 is the intersection edge 117 of two adjacent lens mounting holes 112. A mounting plate 118 is provided on the lens cover 11, and the lens 13 is mounted on the front of the mounting plate 118. There are a plurality of hollow lens mounting holes 112 distributed in a honeycomb structure on the back of the mounting plate 118, and these lens mounting holes 112 include a lens mounting hole 112 located at the center of the lens cover 11 and a plurality of lens mounting holes 112 distributed around the circumference thereof. In this embodiment, the lens mounting hole 112 is a regular hexagonal structure, and it can be understood that the lens mounting hole 112 can also be other shapes; there are a plurality of insert edges 111 on the back of the mounting plate 118, and the insert edges 111 are located on the intersection edge 118 of every two adjacent lens mounting holes 112, and are adapted to the slot 311 of the anti-cross-light cover 31. The beneficial effect of this embodiment is that the honeycomb structured lens mounting holes 112 can effectively increase the structural strength of the lens cover 11 and improve its deformation and pressure resistance. The design of the insert edge 111 effectively prevents the anti-cross-light cover 31 from shifting during use; since the position of the insert edge 111 is closely related to the lens mounting hole 112, the anti-cross-light through hole 312 of the anti-cross-light cover 31 and the lens 13 can be accurately aligned, further improving the anti-cross-light effect.

[0033] As a new implementation method, combined with Figure 1 and Figure 5 , the anti-cross-light cover 31 is also provided with a plurality of anti-cross-light units 313 distributed in a discrete honeycomb structure, and the slots 311 are the spacing areas between two adjacent anti-cross-light units 313. The anti-cross-light units 313 on the anti-cross-light cover 31 include an anti-cross-light unit 313 located at the center of the anti-cross-light cover 31 and a plurality of anti-cross-light units 313 distributed around the circumference thereof. In the present embodiment, the anti-cross-light unit 313 is a hexagonal structure, and it is understandable that the anti-cross-light unit 313 can also be other shapes. The anti-cross-light cover 31 is also provided with a plurality of slots 311, and the slots 311 serve as spacing areas to separate two adjacent anti-cross-light units 313, and the design of the slots 111 makes the anti-cross-light units 313 distributed in a discrete state. The beneficial effect of this embodiment is that such spacing areas provide a stable space for the insertion of the insert edge 111, thereby realizing a stable elastic plug-in connection between the anti-cross-light cover 31 and the lens cover 11. The existence of the slot 311 ensures that the anti-crosstalk cover 31 can move forward and backward along the light path under the action of the elastic telescopic member 33, and the anti-crosstalk units 313 distributed in a discrete honeycomb structure can effectively block the crosstalk of light.

[0034] Embodiment 2

[0035] The difference between the second embodiment and the first embodiment is that the second embodiment, in addition to any one of the implementation modes of the first embodiment, further includes a driving mechanism 4, combined with Figure 6 , the driving mechanism 4 is used to drive the light source assembly 2 or the light output lens assembly 1 to move forward and backward along the optical path to adjust the focal length of the light output lens assembly 1. The driving mechanism 4 mainly includes a motor 41, a screw 42 and a screw fixing sleeve 43. The lens cover fixing plate 12 is installed on the screw 42 through the screw fixing sleeve 43. The beneficial effect of this embodiment is that the focal length is adjusted by changing the relative distance between the light source assembly 2 and the lens 13. There are two ways to change the relative distance between the light source assembly 2 and the lens 13. One way is to fix the light source assembly 2, and the motor 41 drives the light output lens assembly 1 to move forward and backward along the optical path; the other way is to fix the light output lens assembly 1, and the motor 41 drives the light source assembly 2 to move forward and backward along the optical path.

[0036] As a new implementation method, combined with Figures 6 to 9 , the light source assembly 2 or the light output lens assembly 1 moves forward and backward along the optical path so that the anti-cross-light assembly 3 reaches the target state, and the target state includes a natural state and a compressed state; Figure 6 and Figure 7As shown, the elastic expansion member 33 of the anti-cross-light component 3 corresponding to the natural state abuts against the mounting seat 114 of the lens cover 11, and the anti-cross-light cover 31 of the anti-cross-light component 3 does not abut against the light guide column fixing plate 22. At this time, the anti-cross-light cover 31 covers the light output end of the light guide column 21, and the elastic expansion member 33 is in the natural state; Figure 8 and Fig. 9 As shown, the anti-light-crossing cover 31 of the anti-light-crossing assembly 3 corresponding to the compressed state is abutted against the lens cover 11 at one end, and abutted against the light guide column fixing plate 22 at the other end. At this time, the elastic telescopic member 33 is in a compressed state. The light guide column 21 is located above the LED light source and fixed by the light guide column fixing plate 22. The beneficial effect of this embodiment is that when the anti-light-crossing assembly 3 reaches the natural state, the elastic telescopic member 33 is in a natural state, and the anti-light-crossing cover 31 does not abut against the light guide column fixing plate 22; the relative distance between the lens 13 and the light source assembly 2 is far, and the irradiation range of the emitted light beam is small. When the anti-light-crossing assembly 3 reaches the compressed state, the elastic telescopic member 33 is in a compressed state, one end of the anti-light-crossing cover 31 abuts against the light guide column fixing plate 22, and the other end abuts against the lens cover 11; the relative distance between the lens 13 and the light source assembly 2 is close, and the irradiation range of the emitted light beam is large. It can be understood that both states can achieve the effect of anti-light-crossing.
