Description

A reflective structure for an aviation obstruction light Technical Field

[0001] This utility model belongs to the field of aviation obstruction light technology, specifically relating to a reflective structure for an aviation obstruction light. Background Technology

[0002] Aviation obstruction lights are special navigation aids used to mark obstacles such as tall buildings, bridges, and power towers. They outline obstacles at night or in low-visibility conditions by flashing or constant illumination, alerting pilots to avoid collision risks.

[0003] Traditional light source reflectors often employ a single-sided reflection principle (such as parabolic surfaces or curved plates). Limited by the 90° emission angle standard, a large amount of light is blocked on the side of the reflective cavity, resulting in an actual utilization rate of less than 40%. To meet light intensity requirements, manufacturers are forced to increase the power of the light source (such as high-brightness LED arrays), leading to increased power consumption and the need for complex heat dissipation systems. This results in low light efficiency and significant energy waste. Secondly, while using large-sized reflectors (such as integral parabolic surfaces) can improve light concentration, it increases the weight of the luminaire, making it less adaptable to wind loads at heights of 100 meters and increasing installation and maintenance costs. Using a combination of multiple reflectors (such as splicing 2-3 small reflectors) results in low assembly precision, difficulty in aligning the light path, and a tendency for dark areas or uneven light intensity to appear. Summary of the Invention

[0004] The purpose of this invention is to provide an aviation obstruction light reflector structure that significantly widens the reflective angle, featuring a compact layout, lightweight design, and high light efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A reflective structure for an aviation obstruction light, characterized in that it includes a reflective cavity disposed within a light box. The reflective cavity is composed of a strip mirror with a semi-parabolic cross-section and reflective mirrors disposed at both ends of the strip mirror. The bottom of the strip mirror is on the same horizontal plane as the axis of symmetry of the parabola, the top of the strip mirror is the open end of the parabola, the strip mirror is folded inward along the vertical centerline into the reflective cavity, and a plurality of light source beads are arranged at the bottom of the strip mirror.

[0007] Additional technical features constituting the reflective structure of the aforementioned aviation obstruction light also include:

[0008] —The arrangement of the light source LED beads is symmetrical along the vertical center line of the strip mirror and is consistent with the direction of the fold line of the strip mirror;

[0009] —The light source LED is located at the parabolic focal point of the mirror surface of the strip;

[0010] —The angle at which the mirrored strip is folded along the vertical centerline is between 110° and 130°;

[0011] —The top and bottom of the reflective cavity are provided with surrounding mirrors that connect with the strip mirror and the reflective mirror.

[0012] Compared with the prior art, the reflective structure of the aviation obstruction light provided by this utility model has the following advantages: The reflective cavity of the reflective structure is composed of a strip mirror with a semi-parabolic cross-section and reflective mirrors set at both ends of the strip mirror. Compared with the traditional single reflection, this patent has a secondary reflection structure for the light source. Because the strip mirror is folded into the reflective cavity along the vertical center line, the light emitted by the light source beads arranged at the bottom of the strip mirror is reflected by the strip mirror and then refracted again by the reflective mirrors on the side wall of the reflective cavity. The light is emitted symmetrically from the opposite outer side of the reflective cavity, which significantly increases the reflection angle and improves the light energy utilization efficiency. It has the advantages of compact structure, small size and light weight, reasonable layout, uniform light path distribution, economy and durability. Attached Figure Description

[0013] Figure 1 is a schematic diagram of the reflective structure of an aviation obstruction light according to this utility model. Detailed Implementation

[0014] The reflective structure and working principle of the aviation obstruction light provided by this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] In the description of this utility model, unless otherwise stated, the terms "top / bottom" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "set / equipped" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] As shown in Figure 1, the reflective structure of the aviation obstruction light includes a reflective cavity set inside the light box 1. The reflective cavity is composed of a strip mirror (21, 22) with a cross-section of a semi-parabola and reflective mirrors (31, 32) set at both ends of the strip mirror (21, 22). The bottom of the strip mirror is on the same horizontal plane as the axis of symmetry of the parabola, and the top of the strip mirror is the opening end of the parabola. The strip mirror (21, 22) is folded into the reflective cavity along the vertical center line 4. Several light source beads 5 are arranged at the bottom of the strip mirror (21, 22).

[0018] Its working principle is as follows: The reflective cavity of the reflective structure is placed inside a rectangular light box 1 (suitable for high-intensity type B). It consists of strip mirrors (21, 22) with a semi-parabolic cross-section and reflective mirrors (31, 32) set at both ends of the strip mirrors (21, 22). The strip mirrors (21, 22) are arranged such that their bottom is on the same horizontal plane as the parabolic axis of symmetry, and their top is the open end of the parabola. Since the strip mirrors are folded into the reflective cavity along the vertical centerline, their bottom arrangement is as follows: The light emitted by the light source LED beads is reflected by the strip mirrors (21, 22) and then reflected symmetrically to both sides along the vertical center line. It is reflected again by the reflective mirrors (31, 32) to form a secondary reflection structure. Finally, it is emitted from the outer side of the reflective cavity. Compared with the traditional parabolic parallel reflection (primary reflection) which lacks effective reflection on the side, this patent can obtain a wider reflection angle and improve the light energy utilization rate by combining the parabolic inward folding and the reflective mirrors on both sides of the secondary reflection structure.

[0019] In the reflective structure that constitutes the aforementioned aviation obstruction light,

[0020] —To ensure uniform light path and regular reflection of the matrix light source, the arrangement of the above light source LED beads 5 is symmetrical along the vertical center line of the strip mirror (21, 22) and consistent with the direction of the fold line of the strip mirror (21, 22).

[0021] — Preferably, the light source LED 5 is located at the parabolic focal point of the strip mirror (21, 22) to ensure that the light source light emission path is parallel and uniform, avoid problems such as uneven brightness, and make the brightness of the front reflected light source and the side reflected light source basically consistent.

[0022] — Preferably, the angle at which the above-mentioned strip mirrors (21, 22) are folded along the vertical centerline is between 110° and 130°. The smaller the inward folding angle, the more side-reflected light; the larger the inward folding angle, the more front-reflected light. The angle is preferably between 120±5°, which takes into account both the requirements of widening the reflection angle and uniform brightness.

[0023] —In order to further improve the efficiency of light energy utilization, the top and bottom of the above-mentioned reflective cavity are provided with enclosure mirrors (61, 62) that are connected to the strip mirrors (21, 22) and reflective mirrors (31, 32) to reflect all the light emitted by the light source and increase the reflective effect of the obstruction light.

[0024] The above-described embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the implementation of this utility model. Therefore, any other modifications or equivalent substitutions to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
