Description

Technical Field

[0001] This utility model relates to the field of aviation indication technology, specifically to an obstruction light base. Background Technology

[0002] Obstruction lights, as key equipment in the field of aviation warning, provide low-altitude obstacle warnings to aircraft through continuous or intermittent illumination, and are widely used in scenarios such as communication towers, high-rise buildings, and wind power facilities. Their design must meet the standards stipulated by the International Civil Aviation Organization (ICAO) regarding flashing frequency, light intensity, and visibility distance to ensure identification effectiveness under different weather conditions.

[0003] Existing obstruction lights generally use high-brightness light sources, which can meet the needs of long-distance visibility, but have significant light pollution problems: strong light is emitted indiscriminately in all directions, and some light is reflected by the building surface and penetrates the windows, creating continuous interference at night, causing sleep interruption, biological clock disorder and other phenomena for nearby residents, affecting the normal life of nearby residents. Utility Model Content

[0008] Optionally, the mounting piece is hexagonal, and there are six corresponding sub-pieces, each of which is connected to one side of the hexagon.

[0009] Optionally, the sub-piece body has an outwardly convex arc-shaped surface on the inner side of the horn opening.

Detailed Implementation

[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0028] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0029] An obstacle light base, please refer to the appendix. Figure 8One possible implementation includes a lower housing 1 and an upper housing 2 that are detachably connected as a single unit. The lower housing 1 and upper housing 2 form cavities inside each other. The upper housing 2 is a shell structure. The lower housing 1 has a recessed cavity in its middle. The cavity of the upper housing 2 is larger than the cavity of the lower housing 1. The upper housing 2 has a light-transmitting area at least on its top surface, which can be made of colored transparent glass or colored light-transmitting plastic. The system also includes a reflector 3 and a light-emitting element 4 disposed within the cavity. The reflector 3 is funnel-shaped, with its opening facing the top surface of the upper housing 2. The sidewall of the opening is located within the cavity of the upper housing 2. The small end of the funnel shape can be fixed to the lower housing 1, and the tail end hole of the funnel shape can be aligned with the cavity of the lower housing 1. The light-emitting element 4 is located inside the funnel of the reflector 3, and the inner ring surface of the reflector 3 is made of a reflective material. When the light-emitting element 4 emits light, the lateral light illuminates the side of the inner cavity of the funnel and is reflected towards the top area of ​​the upper housing 2.

[0030] In the above embodiments, the detachable structure of the lower shell 1 and the upper shell 2, along with the differentiated cavity design and the positioning of the flared reflector 3 and the light emitter 4, allows lateral light to be reflected by the inner ring surface of the reflector 3 and concentrated towards the light-transmitting area on the top surface of the upper shell 2, thus enhancing the light intensity in the sky direction while suppressing circumferential light scattering. This structure not only improves the effectiveness of aerial warning, ensuring clear identification of the aircraft in the air, but also significantly reduces light interference to surrounding residents through light direction constraint, achieving a dual improvement in functionality and environmental friendliness.

[0031] In one possible implementation, see Appendix Figure 5 , Figure 6 and Figure 9 The reflector 3 includes a mounting plate 31 and a reflector sheet. The mounting plate 31 is located at the small end of the horn opening, and the reflector sheet is the side wall of the horn opening. The reflector sheet includes an end piece 32 and a connecting piece 33. The end piece 32 is cylindrical. Figure 9(As shown) or conical in shape and matched with the cavity of the upper housing 2, that is, the outer diameter of the end piece 32 is slightly smaller than the inner diameter of the upper housing 2 to facilitate assembly. The connecting piece 33 connects between the mounting piece 31 and the end piece 32, and the inner surface of the reflector uses reflective material. For example, high-purity aluminum is rolled into an extremely thin aluminum foil through a special process, and then it is tightly attached to the inner surface of the reflector 3. The aluminum foil has extremely high reflectivity, with a reflectivity of over 90% for visible light, which can effectively reflect the light emitted by the light source 4 in a specified direction. Moreover, the aluminum foil is soft, easy to process and attach, and can adapt to the complex shape of the inner surface of the reflector 3. For another example, high-quality stainless steel is selected and finely polished to achieve a mirror effect. Stainless steel mirror panels have advantages such as high strength, wear resistance, and corrosion resistance, and can maintain good reflective performance for a long time. Installed on the inner surface of the reflector 3, it can withstand a certain amount of external impact and environmental corrosion, and is suitable for obstacle light bases with high requirements for reliability and durability, and can also absorb a certain amount of heat.

[0032] In one possible implementation, see Appendix Figure 9 The connecting piece 33 is conical, or as shown in the image. Figure 9 As shown, the connecting piece 33 includes multiple circumferentially arrayed sub-pieces 331. The sides of adjacent sub-pieces 331 are interconnected. The small end of the sub-piece 331 is connected to the mounting piece 31, and the large end is connected to the end piece 32. Further, the mounting piece 31 is hexagonal, and there are six corresponding sub-pieces 331, each sub-piece 331 being connected to one side of the hexagon. The inner side of the sub-piece 331 at the flared opening is a convex arc-shaped surface 3311. Figure 6 When light is reflected, the reflection of the convex arc surface can make the light be emitted spherically.

[0033] In the above embodiments, the connecting piece 33 adopts a unique design. If it is conical, it can achieve a smooth transition connection. When it is composed of six circumferentially arrayed sub-pieces 331, each sub-piece 331 corresponds to one side of the hexagonal mounting piece 31. This structure allows the reflection to be divided into sections, with each sub-piece 331 being a section. During the light reflection process, the convex arc surface 3311 of the sub-piece 331 located inside the horn mouth allows the light to be reflected spherically. Unlike traditional columnar reflected light, it allows the reflected light to have a certain width range (conical) in the direction towards the sky, greatly increasing the visibility range from the sky. This enables aircraft at different positions in the air to detect the obstruction light signal more clearly and earlier, effectively improving the warning effect and providing stronger protection for flight safety.

[0034] In one possible implementation, see Appendix Figure 7 and Figure 8The light-emitting body 4 includes a substrate 41 and LED beads. Multiple LED beads are attached to the substrate 41. The substrate 41 is fixedly mounted on the mounting plate 31. The LED beads are located on the side facing the opening end of the horn. The mounting plate 31 is provided with a through area for the LED beads to pass through and enter the horn.

[0035] As an alternative to the above embodiments, in this embodiment, the light-emitting element 4 is a light bulb. The mounting plate 31 has a through hole. The tail end of the bulb enters through the through hole in the mounting plate 31 from the opening end of the flared end and is connected to the lamp holder in the lower housing 1. The head end is located inside the flared end. Two different schemes are provided for the light-emitting element 4: one uses a substrate 41 combined with multiple LED beads, with the LED beads attached to the substrate 41 facing the opening end of the flared end. The substrate 41 is fixed to the mounting plate 31, which has a through area for the LEDs to pass through into the flared end. This scheme facilitates high brightness and energy saving. The other scheme uses a light bulb as the light-emitting element 4, with the mounting plate 31 having a through hole. The tail end of the bulb passes through and connects to the lamp holder in the lower housing 1, with the head end located inside the flared end. This scheme has a simple structure and lower cost. One base structure can adapt to these two different light source schemes. In practical applications, users can flexibly choose according to different scenario requirements, cost budgets, and light source characteristics, without needing to redesign or replace the entire base due to changing the light source. This greatly improves the product's versatility and practicality, and reduces usage costs and maintenance difficulty.

[0036] In one possible implementation, see Appendix Figure 4 The upper housing 2 includes a mounting body 21 and a light-transmitting body 22. The light-transmitting body 22 is dome-shaped (it can be semi-circular or arc-shaped). The mounting body 21 is located at the end of the light-transmitting body 22. When the upper housing 2 is fastened to the lower housing 1, the mounting body 21 of the upper housing 2 covers the connecting end 11 of the lower housing 1. In case of rain, this can prevent rainwater from entering the joint surface of the upper and lower housings, eliminating the risk of water ingress into the base, ensuring the normal operation of the internal electronic components, and extending the service life of the base. At the same time, the dome-shaped light-transmitting body 22 and the convex arc surface 3311 of the sub-plate 331 work together to not only block lateral light leakage and reduce the impact of light pollution on surrounding residents, but also project the beam of light into the sky with a certain width, increasing the visibility range and greatly improving the warning effect of the obstruction light on aircraft in the air.

[0037] In one possible implementation, see Appendix Figure 8The upper housing 2 and the lower housing 1 are connected by bolts. The bolts and threaded holes 5 pass through the upper housing 2 from the lower housing 1 in the opposite direction. The threaded holes 5 are preferably countersunk through holes, and the upper housing 2 has inverted threaded blind holes. This special arrangement of the bolts and threaded holes 5, combined with the way the upper housing 2 covers the lower housing 1, effectively prevents external rainwater, dust, and other impurities from entering the base through the connection gaps. This protects the internal electronic components from corrosion and extends the equipment's lifespan. From the perspective of installation stability, the reverse-insertion bolts enhance the tightness and stability of the connection between the upper and lower housings. When facing external interference such as strong winds and vibrations, the absence of exposed threaded holes due to water and dust accumulation prevents bolt corrosion and ensures that the upper and lower housings do not loosen or separate, guaranteeing the continuous and stable operation of the obstruction light and providing reliable protection for flight safety.

[0038] In one possible implementation, see Appendix Figure 2 On the lower housing 1, a protruding ring 12 is provided on the inner side of the end face connecting the upper housing 2 and the lower housing 1. When encountering extreme environments, such as torrential rain or strong winds carrying moisture, even if the special design of the screw holes and the way the upper housing covers the lower housing cause wear and aging due to long-term use, resulting in a decrease in waterproof performance, the protruding ring 12 can still play a crucial role. Thanks to its protruding structure, it effectively prevents water from seeping into the base through the gaps at the connection end face, avoiding short circuits and damage to internal electronic components due to moisture. This ensures that the obstruction lights can still operate stably under harsh conditions, continuously providing reliable warning signals for aircraft and comprehensively protecting flight safety.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
