Description

Technical Field

[0001] This utility model belongs to the field of lighting equipment technology, and in particular relates to a stadium light and its shockproof bracket. Background Technology

[0002] Stadium lights are typically installed on high poles to provide unobstructed illumination. In the stadium environment, the lights and their supports are frequently subjected to various dynamic impacts, including high-speed impacts from balls, accidental collisions with personnel, and strong winds from the top of the poles. These impact loads can easily damage the support structure, especially causing the fixing bolts to loosen, thereby changing the angle of the lights and affecting the lighting effect. Furthermore, high-altitude maintenance and tightening operations are risky and costly.

[0003] Currently, the mainstream connection method is rigid connection (such as welding or direct locking with clamping blocks). Although this structure is simple and robust, it transmits impact energy directly to the connecting parts (bolts) and the lamp body without any buffering when subjected to dynamic impacts. Under continuous, peak stress cycles, the bolts are very prone to loosening due to metal fatigue.

[0004] Therefore, how to solve the problem of the fixing bolts of the stadium lights loosening due to frequent vibration is a technical problem that urgently needs to be solved by those skilled in the art.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0029] Research has revealed the following drawbacks of existing technologies: Currently, the mainstream connection method is a rigid connection (such as welding or direct locking via clamping blocks). While this structure is simple and robust, it transmits impact energy directly to the connecting components (bolts) and the lamp body without any buffering when subjected to dynamic impacts. Under continuous, peak stress cycles, the bolts are highly susceptible to loosening due to metal fatigue.

[0030] Based on the above research, this disclosure provides a stadium light that replaces the traditional rigid connection by introducing a composite flexible connection structure consisting of a hinge shaft and an elastic buffer, thereby forming a buffer system that can dynamically dissipate energy and automatically reset between the support plate and the support column, thus solving the above problems.

[0031] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] See Figure 1This disclosure provides a stadium light, mainly comprising a support column 100, a support plate 200, a hinge shaft 300, at least two lamp heads 400, and at least two elastic buffers 500. The support column 100 is the main support structure of the light fixture, used to fix the entire light fixture to a building roof or other infrastructure. The support plate 200 serves as the mounting base for the lamp heads 400, and is rotatably connected to the support column 100 via the hinge shaft 300. Specifically, the support plate 200 has a shaft hole that mates with the hinge shaft 300, allowing it to rotate within a certain angle around the axis of the hinge shaft 300. At least two lamp heads 400 are respectively mounted on the support plate 200. This arrangement of multiple lamp heads 400 is inherently beneficial for forming a wider and more uniform lighting field. The lamp heads 400 can integrate optical components such as LED modules, driver power supplies, and light-distributing lenses; this is existing mature technology and will not be elaborated upon here. At least two elastic buffers 500 are provided between the support and the pillar 100, forming a flexible connection and buffer system together with the aforementioned hinge shaft 300. When the lamp is subjected to lateral wind, ball impact, or other external impacts, the impact force will first act on the lamp head 400 and the support plate 200. Since the support plate 200 is connected to the pillar 100 via the hinge shaft 300, it has a tendency to rotate around the axis. At this time, the at least two elastic buffers 500 connected between the support plate 200 and the pillar 100 will begin to work. They will be compressed or stretched, thereby effectively absorbing the kinetic energy of the impact and converting it into elastic potential energy. This process greatly attenuates and filters the peak stress and continuous vibration transmitted to the hinge shaft 300, the connection of the support plate 200, and the pillar 100 and its foundation fixing points (especially the bolted connections). Through the synergistic effect of the hinge shaft 300 and the elastic buffers 500, the traditional rigid impact resistance approach is transformed into flexible buffering, solving the long-standing reliability problem of stadium lights in dynamic environments.

[0035] See also Figure 1 In some embodiments, a mounting base 110 is provided at the top of the support column 100. The mounting base 110 is fixed to the support column 100 and has a through hole. A support plate 200 is arranged horizontally, with both ends used to mount lamp holders 400. A downwardly extending hinge seat 210 is provided in the middle of the lower surface of the support plate 200. The support plate 200 is connected to the column via a hinge shaft 300 passing through the hinge seat 210, thereby enabling the entire support plate 200 to rotate around the axis of the hinge shaft 300.

[0036] See also Figure 1In some embodiments, the elastic buffer 500 includes an upper connector 510, an adjusting nut 520, a screw 530, and a spring 540 sleeved on the screw 530. The upper end of the screw 530 is fixedly connected to the upper connector 510. The lower end of the screw 530 passes through a pre-drilled hole in the mounting base 110 on the support column 100 and then engages with the adjusting nut 520, which serves as the lower connector. The spring 540 is sleeved on the outside of the screw 530 and is located between the upper connector 510 and the mounting base 110. When the adjusting screw is tightened, the upper connector 510 is pulled upward through the screw 530, thereby applying an initial compressive force, i.e., a preload, to the spring 540. Therefore, the spring 540 is stably supported and preloaded between the upper connector 510 and the mounting base 110. The top of the upper connector 510 is connected to a hinge seat 210 provided on the lower surface of the support plate 200. This connection can be a hinged connection, the purpose of which is to ensure that the impact force can be effectively transmitted from the support plate 200 to the elastic buffer 500. Thus, the support plate 200 → hinge seat 210 → upper connector 510 → spring 540 → mounting base 110 → support column 100 constitute a complete and clear force transmission and buffering path. The initial compression (preload) of the spring 540 can be adjusted by rotating the adjusting nut 520. This allows the same buffering system to be precisely adjusted according to the on-site wind load conditions and the required buffer stiffness to achieve optimal stability and buffering effect.

[0037] See also Figure 1 In some embodiments, at least two elastic buffers 500 are arranged in a precisely mirror-symmetrical spatial layout. Specifically, a complete elastic buffer 500 is installed between the left connection point of the hinge 210 and the left connection point of the mounting base 110. Another elastic buffer 500 is installed between the right connection point of the hinge 210 and the right connection point of the mounting base 110, with the exact same orientation and dimensions. When the luminaire is subjected to lateral wind loads or eccentric impacts, the impact force is converted into a torque that causes the support plate 200 to rotate about the hinge axis 300. Because the two elastic buffers 500 are symmetrically arranged, their resistance and buffering forces against this rotational torque are equal in magnitude and symmetrical in direction. This eliminates harmful torques that could cause layout imbalance and stress concentration, ensuring that impact energy is evenly and efficiently distributed and absorbed, thereby preventing localized overload or loosening of connections due to uneven stress.

[0038] See also Figure 1In some embodiments, there are two lamp heads 400, symmetrically arranged on both sides of the hinge shaft 300; and there are two elastic buffer members 500, the lower end of which is connected to the mounting base 110 via an adjusting nut 520. The symmetrical dual lamp heads 400 center the system's center of gravity, and the symmetrical dual elastic buffer members 500 provide balanced support. This ensures that the system has no inherent tilting moment when stationary, and when subjected to impact, the impact energy is equally distributed and guided to the left and right buffer channels, achieving a stable buffer posture.

[0039] See Figure 1 Some embodiments also provide a shock-absorbing bracket for a stadium light, comprising: a support plate 200 for supporting a lamp head 400, which is rotatably connected to the support plate 100 via a hinge shaft 300; and at least two elastic buffers 500 connected between the support plate 200 and the support plate 100.

[0040] In summary, the flexible connection structure of this stadium light, consisting of the hinge shaft 300 and the elastic buffer 500, can effectively buffer and absorb external impact energy from wind, ball impacts, etc., and significantly attenuate the vibration and peak stress transmitted to each connecting bolt, thereby preventing the bolts from loosening or fatigue fracture due to long-term alternating stress and improving the structural reliability of the stadium light.

[0041] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not 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. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0043] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0044] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0045] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
