[0002] In the current technical background, stage light fixtures usually rely on imaging effect components to project light spots with specific patterns. Given the strict requirements for the clarity of light spots, the imaging effect components are usually installed inside the light fixture to ensure that clear images are obtained within the imaging range. When the light projected through the effect component is projected onto the imaging surface outside the light fixture, a clear light spot with a specific pattern shape can be formed; at the same time, no visual effects will be caused on the light exit end surface.

[0003] Traditional light shields are mainly used to prevent light crosstalk or glare, and their working principle is to control the irradiation range of the light beam by adjusting the exit angle of the light, without forming a light spot with a specific pattern shape, and without causing any visual changes on the light exit end surface.

DETAILED DESCRIPTION

[0025] The accompanying drawings are combined with theFigure 1 and attached Figure 2 A light shielding piece for producing special visual effects of a lamp, the light shielding piece 1 is detachably and tightly installed on the outer shell of the light emitting end surface 2 of the lamp; the light shielding piece 1 comprises an outer frame 11 matched with the outer shell, a light transmission area 12 in the periphery, and a light shielding area 13 embedded with the light transmission area 12; that is, the shape of the light transmission area 12 and the shape of the light shielding area 13 are mutually complementary and jointly constitute the periphery of the light shielding piece 1; the light shielding area 13 is connected with the outer frame 11, and the light shielding area 13 makes the light emitting rays of the lamp form the visual shielding and diffraction imaging of the light emitting end surface 2 based on the shape of the light shielding area 13. The light shielding piece 1 is also provided with a reinforcing plate 14 for enhancing the structure of the light shielding piece 1 and a cotton sheet 15 for preventing the light shielding piece 1 from scratching the light emitting lens of the lamp; the shape of the reinforcing plate 14 is the same as that of the light shielding piece 1, and the reinforcing plate 14 is installed inside the light shielding piece 1; the cotton sheet 15 is a circular ring plate and is installed between the reinforcing plate 14 and the light emitting lens of the lamp.

[0026] Traditional light shielding piece: The light shielding piece inside the lamp is mainly used to prevent light crosstalk, and the light shielding piece outside the lamp is generally used to reduce glare; both of them control the irradiation range of the emitted light by adjusting the exit angle of the light, both of them cannot form special visual shielding effect on the light emitting end surface, and have little influence on the original optical system, and do not affect the final imaging.

[0027] Traditional imaging effect component: The light transmission area of the imaging effect component located inside the lamp allows the emitted light to pass through, which can project a light spot pattern with the same shape as the light transmission area; that is, the imaging effect component adjusts the distribution of the emitted light to affect the final imaging of the original optical system, but cannot form special visual shielding effect on the light emitting end surface.

[0028] Light shielding piece of the application: The light shielding area 13 on the light shielding piece 1 blocks part of the emitted light, and forms a visual shielding effect on the light emitting end surface 2 with the same shape as the light shielding area 13; another part of the emitted light passes through the light transmission area 12 to realize the redistribution of light intensity outside the lamp, and in this process, the light shielding piece 1 almost has no influence on the final imaging of the original optical system.

[0029] The differences between the light shielding piece 1 of the application and the traditional light shielding piece and the traditional imaging effect component mainly lie in the following aspects:

[0030] The difference from the traditional imaging effect component is that: the traditional imaging effect component is installed inside the lamp, which can affect the final imaging of the original optical system, but cannot form a shielding effect on the light emitting end surface. The light shielding piece 1 of the application is installed outside the lamp, which cannot affect the final imaging of the original optical system, but can form a special visual shielding effect on the light emitting end surface 2.

[0031] The difference between the traditional light shielding piece and the light shielding piece 1 is that the traditional light shielding piece cannot form a visual shielding effect on the light emitting end face, while the light shielding piece 1 can form a visual shielding effect on the light emitting end face 2 by shielding light through the light shielding area 13.

[0032] The embodiment has the advantages that the traditional light shielding piece and the effect assembly are combined to form a special visual shielding effect on the light emitting end face 2, the light shielding piece 1 is externally mounted, and the installation process is significantly simplified.

[0033] As a new embodiment, the light shielding piece 1 is combined with the effect assembly to form a visual shielding effect on the light emitting end face 2. Figure 3 The outer periphery 21 of the light emitting end face 2 is located within the range surrounded by the inner edge 111 of the outer frame 11. In this embodiment, the outer frame 11 is a circular ring structure, the light emitting end face 2 is a circular plane, and the diameter of the light emitting end face 2 is smaller than the diameter of the inner circle of the outer frame 11. When the light rays pass through the light shielding piece 1, only the light shielding area 13 will shield part of the light rays, and the remaining part of the light shielding piece 1 will not shield the light rays. It can be understood that no matter what shape the outer frame 11 and the light emitting end face 2 are, the outer frame 11 will not shield the light rays emitted from the light emitting end face 2. The embodiment has the advantage that it effectively avoids the shielding of light rays by other parts outside the light shielding area 13, and forms a visual shielding effect on the light emitting end face 2 that is determined only by the shape of the light shielding area 13.

[0034] As a new embodiment, the light shielding piece 1 is combined with the effect assembly to form a visual shielding effect on the light emitting end face 2. Figure 1 The light shielding piece 1 is mounted on the shell through the outer frame 11. The outer frame 11 is a circular ring-shaped flat structure, and the outer diameter of the outer frame 11 is consistent with the outer diameter of the shell, ensuring the fit and aesthetics of the installation of the light shielding piece 1. Traditional light shielding pieces are generally mounted on the outside or inside of the lamp through fasteners, and cannot be disassembled without tools. In this embodiment, the installation methods of the outer frame 11 include but are not limited to vacuum adsorption, magnetic adsorption, adhesive adsorption, or other effective adsorption means, which are designed to achieve tool-free disassembly. The embodiment has the advantage that it greatly facilitates the installation and replacement process of the light shielding piece 1 and improves user maintenance efficiency.

[0035] As a new embodiment, the light shielding piece 1 is combined with the effect assembly to form a visual shielding effect on the light emitting end face 2. Figure 2The light shielding piece 1 is further provided with a plurality of magnets 3 arranged uniformly on the outer frame 11, and the inner portion of the outer frame 11 is provided with a plurality of installation grooves 112 for installing the magnets 3. The magnets 3 are circular plates, and the diameter of the magnets 3 is smaller than the width of the outer frame 11. The magnets 3 are installed in the installation grooves 112 by adhesive. The shell of the lamp is usually made of metal material, which is convenient for the magnets to be adsorbed. Therefore, the light shielding piece 1 can be adsorbed on the shell at the light emitting end surface 2 of the lamp by the magnets 3. It can be understood that the light shielding piece 1 can also be adsorbed and installed on the shell at the light emitting end surface 2 of the lamp by other means. The beneficial effect of this embodiment is that the user only needs to place the light shielding piece 1 on the shell at the light emitting end surface 2 of the lamp, and the magnets 3 on the outer frame 11 will be automatically adsorbed on the shell, realizing quick installation.

[0036] As a new embodiment, in combination with the accompanying drawings Figure 1 The outer edge of the outer frame 11 is further provided with a protrusion 113 or a handle for facilitating installation or removal. In this embodiment, a rectangular plate-shaped protrusion 113 is arranged on the lower surface of the outer edge of the outer frame 11. The main purpose of the protrusion 113 is to facilitate the disassembly operation of the light shielding piece 1. The operator can easily disassemble the light shielding piece 1 from the installation position by the protrusion 113. In addition, when the operating structure arranged on the outer edge of the outer frame 11 is in the form of a handle, the operator can also conveniently complete the disassembly work of the light shielding piece 1 by holding the handle. The beneficial effect of this embodiment is that the convenience of disassembling the light shielding piece 1 is significantly improved, providing users with a more efficient operation experience.

[0037] As a new embodiment, in combination with the accompanying drawings Figure 1 The light shielding piece 1 is made of light shielding material or semi-transparent material. When the light shielding piece 1 is made of light shielding material, the emergent light will form a visual shielding effect matching the shape of the light shielding area 13 on the light emitting end surface 2 after passing through the light shielding piece 1. Common light shielding materials include metal materials, ceramic materials, rubber materials, and plastics, etc. Considering the installation convenience and weight requirement of the light shielding piece 1, plastics become the preferred material of the light shielding piece 1 due to its light weight, low cost, and high temperature resistance, etc. If the light shielding piece 1 is made of semi-transparent material, the light shielding area 13 will block and scatter part of the light, resulting in that the brightness of the light shielding area 13 on the light emitting end surface 2 is slightly dimmer than that of the light transmitting area 12. Common semi-transparent materials include various glasses, PC plates, and acrylic plates, etc. Considering the installation convenience and weight factors of the light shielding piece 1, PC plates and acrylic plates become the ideal choice of the material of the light shielding piece 1 due to their light weight and low cost advantages. The beneficial effect of this embodiment is that different materials can create diversified visual effects on the light emitting end surface 2, and users can flexibly select the light shielding piece 1 made of different materials according to actual needs to meet specific visual effect requirements.

[0038] As a new embodiment, in combination with the accompanying drawings Figure 1The light-shielding area 13 is a composite shape blocking structure. Different shapes of the light-shielding area 13 result in different visual blocking effects on the light-emitting end face 2. It is understood that the shape of the light-shielding area 13 is not limited to a single shape; it can also be various other composite shapes, such as flower shapes, five-ring shapes, leaf shapes, or rhombuses. The beneficial effect of this embodiment is that variations in the shape of the light-shielding area 13 can provide more diverse visual blocking effects.

[0039] The working principle of this invention is as follows: When light is emitted from the light-emitting end face 2 of the lamp, it first passes through the light-shielding member 1 installed outside the lamp; the light-shielding area 13 on the light-shielding member 1 blocks part of the emitted light, and forms a visual shielding effect with the same shape as the light-shielding area 13 on the light-emitting end face 2; at the same time, the unblocked light passes smoothly through the light-transmitting area 12 of the light-shielding member 1 and continues to redistribute the light intensity outside the lamp, so that the light-shielding member 1 has a negligible impact on the final imaging of the original optical system.

[0040] Example 1

[0041] As attached Figure 3 As shown, the composite shape blocking structure is a curved blocking structure. The boundary of the light-blocking area 13 is also composed of a series of curves or arcs, so the boundary of the visual effect formed on the light-emitting end face 2 is also composed of curves or arcs. If the light-blocking area 13 is designed as a five-ring shape, its boundary is composed of circles or arcs; it can form the same visual blocking effect as the five-ring shape on the light-emitting end face 2. In this embodiment, the visual blocking effect formed by the light-blocking area 13 on the light-emitting end face 2 is similar to the effect of a computer power button, and this visual blocking effect is composed of curves and arcs. The beneficial effect of this embodiment is that it enriches the diversity of the visual effects formed by the light-blocking component 1, providing customers with a wider range of choices.

[0042] Example 2

[0043] The difference between Example 2 and Example 1 lies in the shape of the light-shielding area 13. (See attached image.) Figure 4 As shown, the composite shape blocking structure is a polygonal blocking structure. The light-blocking area 13 is mainly composed of straight line segments, and the shape of the light-blocking area 13 itself affects the visual blocking effect formed on the light-emitting end face 2. For example, when the light-blocking area 13 is designed in the shape of a pentagram, the light-emitting end face 2 will present the same visual blocking effect as the pentagram shape. In addition, the shape of the light-blocking area 13 can also be hexagonal, heptagonal, octagonal, or other polygonal shapes composed of straight line segments. The beneficial effect of this embodiment is that by changing the shape of the light-blocking area 13, the diversity of the visual effects formed by the light-blocking member 1 on the light-emitting end face 2 is enriched, thereby providing customers with more diversified choices.

[0044] Example 3

[0045] The difference between Example 3 and Example 1 lies in the shape of the light-shielding area 13. (See attached diagram.) Figure 5 As shown, the composite shape blocking structure is a hybrid linear blocking structure. The boundary of the light-blocking area 13 integrates straight lines and curves, so the boundary of the visual blocking effect formed by the light-blocking area 13 also presents a combination of straight lines and curves. For example, when the light-blocking area 13 is designed as a fan shape, a visual blocking effect with the same shape as the fan-shaped light-blocking area 13 will be formed on the light-emitting end face 2. The beneficial effect of this embodiment is that by combining straight lines and curves, the diversity of the visual effects formed by the light-blocking component 1 is enriched, providing customers with a wider range of choices.
