Description
Technical Field
[0001] The utility model relates to the technical field of stage lamps, in particular to a stage lamp with a built-in shielding cover. Background Art
[0002] With the development of stage lighting technology, in order to meet market demand, stage lights also tend to be miniaturized and lightweight. Under the premise of ensuring functionality, the smaller the size and weight of the stage lights, the better. Therefore, the space inside the stage lights is very limited. However, in order to avoid friction damage between the light processing module inside the stage lights and the inner wall of the lamp body shell when adjusting the imaging up and down, a certain gap still needs to be left between the light processing module inside the stage lights and the lamp body shell. However, the existence of the above gap will expose the internal parts and affect the appearance of the entire product. In short, when the user observes the inside of the lamp head through the light output lens of the stage light, it is easy to see the parts inside the lamp head through the gap between the light processing module and the lamp body shell, making the internal parts of the lamp head easy to be observed by the outside world, which will affect the overall aesthetics of the stage light product. In addition, when the light source inside the stage light emits light, the light of the light source is easy to penetrate outward through the gap between the light processing module and the lamp body shell, resulting in light leakage.

[0009] According to the stage light with a built-in shielding cover of the utility model, the installation ring extends to the outside of the light processing module by a certain width to shield the gap between the inner wall of the shell and the light processing module.
[0010] According to the utility model of a stage lamp with a built-in shielding cover, the annular shielding cover and the mounting ring are both made of silicone.
[0011] According to the stage light with built-in shielding cover of the utility model, a plurality of sockets are arranged around the end surface of the mounting ring;
[0012] The annular shielding cover is provided with a plurality of elastic connecting pieces which are respectively inserted into the respective insertion holes on one side close to the mounting ring.
[0013] According to the stage lamp with a built-in shielding cover of the utility model, each of the elastic connecting pieces is a rubber nail.
[0014] According to a stage lamp with a built-in shielding cover of the utility model, a limiting protrusion is provided on the outer side of the elastic connecting piece, the diameter of the limiting protrusion is larger than the diameter of the insertion hole, and the limiting protrusion is inserted into the insertion hole to fix the annular shielding cover.

[0016] According to the stage lamp with a built-in shielding cover of the utility model, the elastic connecting piece and the annular shielding cover are formed in one piece.
[0017] According to the stage light with a built-in shielding cover of the utility model, the annular shielding cover is arranged separately from one end of the light emitting lens close to the light emitting lens.
[0018] According to the stage light with a built-in shielding cover of the utility model, the length of the annular shielding cover in a free state along the light path direction of the light source is 15 mm-30 mm, preferably 20 mm.
[0019] According to the utility model of a stage light with a built-in shielding cover, a screw motor which is transmission-connected to the light processing module is arranged in the shell, and the light processing module is driven to reciprocate along the direction of the light path of the light source by the screw motor.
[0020] According to the stage lamp with built-in shielding cover of the utility model, a guide rail extending along the light path direction of the light source is arranged in the shell, and a slider slidably fitted in the guide rail is arranged at the edge of the light processing module.
[0021] According to the stage light with a built-in shielding cover of the utility model, the annular shielding cover is a circular ring, a rectangular ring, a polygonal ring, or a triangular ring that matches the shape of the outer edge of the light processing module.
[0022] The utility model discloses a stage lamp with a built-in shielding cover. An annular shielding cover is additionally arranged on a light processing module in a lamp head shell, so that the annular shielding cover is in the space between the light processing module and a light output lens to shield the gap between the outer side of the light processing module and the shell, thereby preventing a user from easily seeing the components inside the lamp head through the gap between the light processing module and the shell, making it difficult for the internal components of the lamp head to be observed by the outside world, and when the light source inside the stage lamp emits light, the light of the light source is also not easy to penetrate outward through the gap between the outer side of the light processing module and the shell, thereby preventing the problem of light leakage inside the lamp head. In addition, since the annular shielding cover is arranged on the light processing module and can move along the direction of the light path of the light source with the light processing module, the annular shielding cover will not interfere with the light processing module in a moving state. Furthermore, since the annular shielding cover is foldable, in a non-folded state, the annular shielding cover elastically stretches a certain length along the light path of the light source toward the direction of the light output lens, which can be more conducive to shielding the gap between the outer side of the light processing module and the outer shell, ensuring that the user cannot easily see the gap between the outer side of the light processing module and the outer shell of the lamp holder from the side of the light output lens, and the inside of the lamp holder Parts and light sources are not easily exposed. When the light processing module needs to approach the light output lens along the direction of the light source light path during operation and movement, the annular shielding cover can be squeezed by the light processing module and the light output lens and synchronously produce adaptive folding and contraction, so it will not hinder the operation of the light processing module and will not affect the normal operation of the internal mechanism of the lamp head. When the light processing module is away from the light output lens, the annular shielding cover can be elastically reset and restored to the state of stretching in the direction of the light output lens, and continue to block the gap between the outside of the light processing module and the outer shell. It can be seen that the technical solution of the utility model can not only prevent the internal parts of the lamp head from being easily observed by the outside world and avoid the problem of easy light leakage inside the lamp head, but also will not affect the normal operation of the internal mechanism of the lamp head.

[0038] like Figures 1 to 10As shown, a stage light with a built-in shielding cover in this embodiment, the main structure of the stage light includes a lamp head and a shell 1 wrapped around the lamp head, and includes a light source 2 installed inside the shell 1, and a light output lens 3 is also installed on the shell 1, and the light output lens 3 corresponds to the light path of the light source 2. Inside the shell 1, a light processing module 4 is installed between the light output lens 3 and the light source 2, and the light processing module 4 can move along the direction of the light path of the light source. Optionally, in this embodiment, the light processing module 4 is an amplifying module for focusing the stage light. Specifically, a plurality of optical lenses 44 are mounted on the light processing module 4, and a screw motor 43 connected to the light processing module 4 is installed in the shell 1, so that the light processing module 4 can be driven by the screw motor 43 to move back and forth along the direction of the light path of the light source to achieve the focusing function. The light source 2 includes a chip board 21 and a plurality of light guides 22. Each light guide 22 is distributed on the chip board 21. The light generated by the chip board 21 passes through a plurality of light guides 22 in sequence, and finally penetrates the optical lens 44 and the light output lens 3, so that the lamp head of the stage lamp can project a light beam outward. In addition, a retractable annular shielding cover 5 for shielding the inner wall of the outer shell 1 is provided on the periphery of the light processing module 4. The annular shielding cover 5 is foldable. The annular shielding cover 5 is provided in the space between the light processing module 4 and the light output lens 3. The annular shielding cover 5 is separated from the light output lens 3 at one end thereof, that is, the annular shielding cover 5 is not connected to the light output lens 3. The free state length of the annular shielding cover 5 along the light path direction of the light source is 15mm-30mm, and the preferred length in this embodiment is 20mm. The annular shielding cover shrinks when squeezed by the light output lens 3. , the upper and lower ends of the annular shielding cover 5 are open, and the two openings correspond to the light processing module 4 and the light output lens 3 respectively. In this embodiment, the annular shielding cover 5 is located on the upper side of the light processing module 4, that is, the annular shielding cover 5 is located on the side of the light processing module 4 close to the light output lens 3, and the annular shielding cover 5 has a certain lateral width in the space between the light processing module 4 and the light output lens 3 (that is, it has a certain width in the direction perpendicular to the light path of the light source), so that the annular shielding cover 5 blocks the gap between the outer side of the light processing module 4 and the lamp holder housing 1. In addition, the annular shielding cover 5 elastically stretches a certain length along the light path of the light source toward the light output lens 3, and the annular shielding cover 5 can be synchronously folded and contracted when squeezed by the light processing module 4 and the light output lens 3.
[0039] It can be understood that in this embodiment, an annular shielding cover 5 is additionally provided on the light processing module 4 in the lamp head, so that the annular shielding cover 5 is in the space between the light processing module 4 and the light output lens 3 to block the gap between the outside of the light processing module 4 and the outer shell 1. In this way, it is possible to prevent users from easily seeing the components inside the lamp head through the gap between the light processing module and the outer shell, so that the internal parts of the lamp head are not easily observed by the outside world, and when the light source inside the stage light emits light, the light of the light source is not easy to penetrate outward through the gap between the outside of the light processing module and the outer shell of the lamp body, thereby avoiding the problem of light leakage inside the lamp head. In addition, since the annular shielding cover 5 is provided on the light processing module 4 and can move along the direction of the light path of the light source with the light processing module 4, the annular shielding cover 5 will not interfere with the light processing module 4 in a moving state. Furthermore, since the annular shielding cover 5 is foldable, in a non-folded state (such as Figure 7 As shown in the figure, the annular shielding cover 5 elastically stretches a certain length along the light path of the light source toward the light output lens 3, which is more conducive to shielding the gap between the outer side of the light processing module 4 and the housing 1, ensuring that the user cannot easily see the gap between the outer side of the light processing module 4 and the housing 1 from the side of the light output lens 3, and the parts inside the lamp head and the light source are not easily exposed. When the light processing module 4 needs to move closer to the light output lens 3 along the direction of the light path of the light source during work (such as Figure 8 As shown in the figure, the annular shielding cover 5 can be adaptively folded and contracted synchronously due to the squeezing of the light processing module 4 and the light output lens 3, so it will not hinder the operation of the light processing module 4, and will not affect the normal operation of the internal mechanism of the lamp holder. When the light processing module 4 is away from the light output lens 3, the annular shielding cover 5 can be elastically reset and resume the state of stretching toward the light output lens 3, and continue to block the gap between the outside of the light processing module 4 and the housing 1. It can be seen that the technical solution of the utility model can not only prevent the internal parts of the lamp holder from being easily observed by the outside world and avoid the problem of easy light leakage inside the lamp holder, but also will not affect the normal operation of the internal mechanism of the lamp holder.
[0040] Specifically, the annular shielding cover 5 is a spring telescopic cover, and the annular shielding cover 5 is preferably made of silicone. The structure of the spring telescopic cover is similar to the ink spring bottle structure used to store printer ink in the prior art. Its side wall is a continuous toothed sheet with a serrated side wall 51. The upper and lower ends of the spring telescopic cover are respectively provided with openings, and the two openings correspond to the light processing module 4 and the light output lens 3. The serrated side wall 51 of the spring telescopic cover occupies a certain width in the direction perpendicular to the light path of the light source, so as to block the gap between the outer side of the light processing module 4 and the housing 1. That is to say, the annular shielding cover 5 is set as a spring telescopic sleeve so that the side wall of the annular shielding cover 5 has a serrated side wall 51. This structure not only allows the annular shielding cover 5 to have a certain elastic reset ability in the axial direction, ensuring that the annular shielding cover 5 can automatically rebound after being released and compressed, and continue to extend to a certain length in the direction of the light output lens 3, but also allows the annular shielding cover 5 to have a certain width in the radial direction, maintaining the gap between the outer side of the light processing module 4 and the lamp holder housing 1, ensuring that the user is not easy to see the gap between the outer side of the light processing module 4 and the housing 1 from the side of the light output lens 3, and the parts inside the lamp holder and the light source are not easily exposed.
[0041] Specifically, a mounting ring 41 is fixed to the periphery of the light processing module 4, and the mounting ring 41 is located on a side close to the light output lens 3. The annular shielding cover 5 and the mounting ring 41 are coaxially connected to each other, so that the annular shielding cover 5 can be installed on the light processing module 4. The annular shielding cover 5 and the mounting ring 41 are both made of silicone material, so that both have more obvious elasticity. In addition, the mounting ring 41 extends a certain width to the outside of the light processing module 4, so as to further block the gap between the inner wall of the housing 1 and the light processing module 4.
[0042] More specifically, in order to facilitate the easy installation of the annular shielding cover 5, the end face of the mounting ring 41 is surrounded by a plurality of sockets 42. Accordingly, the annular shielding cover 5 is fixed with a plurality of coaxial elastic connectors corresponding to the respective sockets 42 on the side close to the mounting ring 41. Specifically, the elastic connector of this embodiment is a rubber nail 52, and the rubber nail 52 is integrally formed with the annular shielding cover 5 to facilitate integral manufacturing. When the annular shielding cover 5 needs to be installed on the light processing module 4, it is only necessary to insert the rubber nails 52 on the annular shielding cover 5 into the respective sockets 42 on the end face of the mounting ring 41. The installation process is simple and convenient, ensuring the accurate positioning of the annular shielding cover 5 on the light processing module 4, and the rubber nails 52 also have the performance of buffering external vibrations.
[0043] Optionally, a limiting protrusion 53 is provided on the outer side of the rubber nail 52, and the diameter of the limiting protrusion 53 is larger than the diameter of the insertion hole 42. When installing, the limiting protrusion 53 and the rubber nail 52 are inserted into the insertion hole 42 together. It can be understood that when the limiting protrusion 53 and the rubber nail 52 enter the insertion hole 42, the limiting protrusion 53 will be squeezed and shrunk. After the limiting protrusion 53 completely enters the insertion hole 42, the limiting protrusion 53 returns to its original state, thereby limiting the rubber nail 52 from leaving the insertion hole 42, thereby fixing the annular shielding cover 5, and the installation is more stable.
[0044] Specifically, a guide rail 6 is provided inside the housing 1, and the guide rail 6 extends along the light path of the light source. Accordingly, a slider (not shown in the figure) is provided on the edge of the light processing module 4, and the slider slides in the guide rail 6, thereby ensuring the stable movement of the light processing module 4.
[0045] It should be noted that in actual applications, the outer edge shape of the light processing module 4 is diverse, for example, it can be a circular ring, or a rectangular ring, a polygonal ring, or a triangular ring. Matchingly, the shape of the annular shielding cover 5 can also be set to a circular ring, a rectangular ring, a polygonal ring, or a triangular ring.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
