Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

In addition, the terms "first", "second" and the like are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, can be fixedly connected, or can be detachably connected, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium, or can be connected inside two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0037] The reflective cup in the present application is mainly used for aviation obstruction lights. By changing the specific structure of the existing aviation obstruction light reflective cup, the reflection effect of the reflective cup is improved, the scattering effect of the reflected light is reduced, and the dazzling effect on the pilots is avoided.

[0038] Referring to Figure 1 , and combining Figures 2-6 , the reflective cup in the present application, the main structure includes a reflective cup body 1, the reflective cup body 1 includes a cup body structure with two open ends and an overall arc-shaped conical shape, which can reflect and focus light through the arc-shaped conical structure.

[0039] Specifically, the overall arc-shaped conical reflective cup body 1 in the present application includes an arc-shaped surface of a parabolic cross section, which can reflect the light emitted by a point light source into a parallel light beam.

[0040] The light cup body 1 comprises a circumferential ring-shaped light cup wall 11, and the light cup wall 11 is composed of a plurality of arc surfaces.

[0041] By arranging the scale surface 2 on the outer side wall of the light cup wall 11, the scattering of light can be reduced, the reflected light can maintain high uniformity in the light band, the pilot glare can be effectively avoided, and clear illumination can be provided.

[0042] It should be pointed out that the light cup in the utility model adopts a multi-light source form, and the same shape edge structure is uniformly arranged on the scale surface 2 of the outer side wall of the light cup wall 11, that is, by arranging the same shape edge structure on the outer side wall of the arc surface, the illumination uniformity of each region can be improved.

[0043] The main function of the scale surface 2 is reflected in the light mixing effect, which can improve the part of the light spot defects of the light source to a certain extent without significantly increasing the light emitting angle, thereby effectively enhancing the high uniformity of the reflected light in the light band.

[0044] The light cup body 1 comprises a necked end 12, the necked end 12 is provided with a connecting surrounding plate 13, the connecting surrounding plate 13 is provided with a clamping structure 3, the clamping structure 3 can realize the clamping cooperation of the light cup body 1 on the aviation obstruction light, reduce the difficulty of connection operation, and improve the installation efficiency.

[0045] In one specific embodiment, the light cup body 1 is a split structure, comprising a plurality of cup petals 1a which are the same in shape, and each cup petal 1a comprises an arc structure with a parabolic cross section, which is used to form the arc cup wall of the light cup body 1. By arranging the scale surface 2 on the outer side wall of the arc cup wall of each cup petal 1a, the uniformity of the reflected light can be ensured.

[0046] The wall surface of the light cup is usually designed as an arc surface to realize effective reflection and focusing of light, and the parabolic arc surface structure can reflect the light emitted by the point light source into a parallel light beam. From the angle of the arc surface, it corresponds to the opening angle of the parabola, and the angle is related to the curvature radius and focal position of the parabola. Generally speaking, the light cup with a smaller arc surface angle produces a narrow light beam, which is suitable for occasions requiring long-distance illumination; and the light cup with a larger angle produces a wide light beam, which is suitable for occasions requiring wide-area illumination.

[0047] In order to consider the arrangement of the scale surface 2 on the outer side wall and ensure effective illumination, the arc surface angle in the utility model is 50-55°.

[0048] Further, in order to form the overall structure of the reflector cup 1, the lateral edges of adjacent cup petals 1a are butted against each other, and the butted portions are provided with arc-shaped connecting strips 1b, which mainly serve to strengthen the structural strength of the connecting portions, and the direction of the continuous extension of the arc-shaped connecting strips 1b on the arc-shaped conical cup is parallel to the axial direction of the reflector cup 1.

[0049] The arc-shaped connecting strips 1b are arranged on the outer side wall of the reflector cup 1, and the outer side wall of the cup petals 1a and the arc-shaped connecting strips 1b together constitute the reflecting surface of the reflector cup 1, ensuring that the circumferential outer side wall of the reflector cup 1 constitutes a complete reflecting surface.

[0050] In the embodiment, the flared end 16 of the reflector cup 1 is provided with a circular reflector cup mouth 14, and a reinforcing inclined plate 15 is arranged between the inner side wall of each cup petal 1a and the reflector cup mouth 14, mainly for the purpose of strengthening the overall structural strength of the reflector cup 1. The reinforcing inclined plate 15 is arranged at the flared end 16 of the reflector cup 1, and smoothly transitions between the cup petals 1a and the reflector cup mouth 14, thereby enhancing the connecting strength of the reflector cup mouth 14 and the cup petals 1a on the inner side, and ensuring smooth transition and connection.

[0051] Further, the reinforcing inclined plate 15 is arranged at the middle part of the cup petals 1a, the parts of the cup petals 1a on both sides of the reinforcing inclined plate 15 are connected with the reflector cup mouth 14, and the outer side wall of the reflector cup 1 at the connecting portions is not provided with a scale surface 2. The absence of the scale surface 2 at this part is determined by the specific position thereof, because the connecting portions correspond to the connecting portions of different cup petals 1a, and the connecting portions need to be structurally strengthened, and the outer side of the connecting portions is transitioned to a straight-cylindrical structure region, so that the arc-shaped reflecting surface loses its significance. By reducing the processing area of the scale surface 2, the processing difficulty is reduced, and the cost is saved.

[0052] Based on the structural angle of the outer side of the reflector cup 1, reinforcing ribs 17 and connecting columns 18 are arranged between adjacent cup petals 1a on the inner side of the reflector cup 1. The reinforcing ribs 17 and the connecting columns 18 are arranged at the inner side of the flared end 16, which can take into account the overall structural strength of the reflector cup 1, and facilitate connection through the connecting columns 18.

[0053] The root of the connecting column 18 is connected with the inner side wall of the cup petal 1a, one side of the reinforcing rib 17 is butted against the side wall of the connecting column 18, and the other side of the reinforcing rib 17 is connected with the inner side wall of the reflector cup mouth 14.

[0054] In another specific embodiment, from the perspective of facilitating the clamping installation of the reflector cup, the outer side edge of the connecting surrounding plate 13 is connected with the bottom inner side wall of the reflector cup wall 11, which can make the bottom wall of the connecting surrounding plate 13 as the bottom wall of the reflector cup body 1 itself, and ensure effective clamping.

[0055] The inner side edge of the connecting surrounding plate 13 constitutes the mounting port of the reflector cup body 1, the clamping opening 19 with a groove structure is arranged on the mounting port, and the clamping structure 3 is arranged at the clamping opening 19, specifically, the clamping structure 3 can be elastically deformed, and the interference between the clamping structure 3 and the reflector cup body 1 can be reduced by arranging the clamping structure 3 at the clamping opening 19.

[0056] The clamping structure 3 comprises a connecting frame 31 and a clamping claw 32 which are arranged integrally, and the connecting frame 31 is a bending structure and can have a certain elastic deformation amount.

[0057] Further, the root of the connecting frame 31 is connected with the top wall of the connecting surrounding plate 13, and the clamping claw 32 is arranged outward and protrudes from the bottom wall of the connecting surrounding plate 13, and the clamping claw 32 protruding from the bottom wall of the connecting surrounding plate 13 can be matched with the clamping hole on the lamp holder, so that the bottom of the reflector cup is clamped on the lamp holder.

[0058] The connecting column 18 at the inner side of the flared end 16 can be in the structure form of a threaded connecting column 18, which is mainly used for connecting the peripheral assembly at the top of the reflector cup, so as to ensure that the reflector cup is effectively and reliably connected and installed.

[0059] The utility model discloses a scale armor 2 is arranged on the outer side wall of the reflector cup, which can greatly improve the uniformity of reflected light in the light band.

[0060] Referring to Figures 7-8 , it can be directly observed through comparison that, in the state without the scale armor 2, the light is directly reflected to the working surface through the reflecting surface.

[0061] After the scale armor 2 is arranged, the mixed light effect of the reflected light is enhanced, the distribution of the reflected light is more uniform, and the part of the light spot defects of the light source is improved to a certain extent without significantly increasing the light emitting angle.

[0062] The utility model also provides an aviation obstruction light, which comprises a lamp holder and the reflector cup described above, and the reflector cup is connected to the lamp holder through the clamping structure, which can improve the installation efficiency and improve the lighting effect of the aviation obstruction light.

[0063] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0064] The above descriptions are only the preferred embodiments of the present application, and are not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
