Abstract
Description
Technical Field
[0001] This invention belongs to the field of energy-saving lighting technology, and in particular relates to an LED energy-saving stadium light. Background Technology
[0002] To provide adequate lighting for the stadium, stadium lights are typically installed. Considering the large area of the stadium, stadium lights are mostly installed at high positions to provide illumination for the entire stadium. Existing stadium lights adopt a modular design, with multiple LED lighting modules installed horizontally or vertically on the mounting bracket to achieve energy-saving lighting over a wide area.
[0003] In existing technologies, LED energy-saving stadium lights are usually installed in a fixed manner at high places. Since LED energy-saving stadium lights are exposed to the external environment for a long time, when they encounter severe weather such as thunderstorms, the exposed stadium lights are easily affected, which will accelerate the aging of the entire stadium light or reduce its service life.
[0004] Meanwhile, during operation, flying insects are easily attracted to the light surface due to phototaxis. The insects attached to the light surface are prone to die due to the high temperature of the light surface, resulting in a large number of dead insects contaminating the light surface. Since the sports lights are mostly installed on poles more than ten meters high, the maintenance cost of manually climbing to clean up the dead insects and accumulated dust is extremely high. If they are not cleaned for a long time, it will lead to serious light decay and poor heat dissipation, which will affect the normal service life and lighting quality of the LED energy-saving sports lights. Summary of the Invention
[0005] The purpose of this invention is to provide an LED energy-saving stadium light. Through the specific structural design of the ball light frame, lampshade assembly, end sealing assembly, opening and closing power assembly, lifting control assembly, and guide wheel pushing part, the invention solves the problem that existing stadium lights are easily affected by severe weather such as thunderstorms or dead flying insects, which in turn affects the normal use of LED energy-saving stadium lights.
[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention is an LED energy-saving stadium light, including a stadium light frame, including an inclined guide part and a guide wheel lifting part corresponding to the inclined guide part; an LED lamp body, installed on the top of the stadium light frame, each LED lamp body corresponding to an inclined guide part and a guide wheel lifting part; a lamp cover assembly, slidably disposed on the stadium light frame for covering the LED lamp body; an end sealing assembly, slidably disposed on the inclined guide part for sealing the inclined opening of the lamp cover assembly, and horizontally slidingly cooperating with the guide wheel lifting part; an opening and closing control mechanism, consisting of an opening and closing power component and a lifting control component that rotates synchronously with the opening and closing power component, a guide wheel pushing part installed on one side of the lamp cover assembly, the guide wheel pushing part and the opening and closing power component being driven by a guide groove, and the lifting control component and the guide wheel lifting part being driven by a guide groove.
[0007] The present invention is further configured such that the spherical lamp assembly frame also includes a spherical lamp carrier, an electrical control box is fixed at the center of the bottom of the spherical lamp carrier, a fitting ring seat is fixed at the bottom of the electrical control box, and a mounting groove for mounting LED lamp bodies is provided at the top of the spherical lamp carrier, with one side of the lamp surface of the LED lamp body extending out of the spherical lamp carrier.
[0008] The invention is further configured such that the inclined guide portion consists of an inclined guide frame and a support frame that are fixedly connected. The support frame is fixed between the electrical control box, the inclined guide frame and the ball lamp carrier, and an L-shaped conduit extending downward is installed on the top of the ball lamp carrier.
[0009] The present invention is further configured such that the guide wheel lifting part includes a lifting seat disposed above the ball lamp carrier, a guide rod that slides through the ball lamp carrier is fixed at the bottom of the lifting seat, a lifting rod is horizontally slidably disposed on the lifting seat, and a guide wheel is rotatably mounted on the end of the lifting rod near the opening and closing control mechanism.
[0010] The present invention is further configured such that the lampshade assembly includes a protective cover, one side of the inclined surface of the protective cover is an open structure, and the side of the protective cover opposite the inclined surface is provided with a U-shaped opening adapted to the ball lamp carrier, and a connecting plate fixed to the protective cover is provided above the U-shaped opening.
[0011] The present invention is further configured such that the end sealing assembly includes an end sealing plate slidably disposed within an inclined guide frame, an L-shaped support plate horizontally arranged fixed on the top of the end sealing plate, a positioning tube fixedly disposed through one side of the L-shaped support plate, the positioning tube being slidably sleeved on the lifting rod and connected by fasteners, and a lamp surface brush fixedly installed below the L-shaped support plate and fixedly mounted with the end sealing plate.
[0012] The present invention is further configured such that the opening and closing power assembly includes a power motor installed in an electrical control box, the output shaft of the power motor passes through the ball lamp carrier and is connected to a flat push drive seat, the top of the flat push drive seat is provided with a flat push groove corresponding to the flat push part of the guide wheel, and the top of the flat push drive seat is provided with a mounting hole.
[0013] The present invention is further configured such that the guide wheel pushing part includes a guide wheel pushing plate fixed to the top of the connecting plate by fasteners, a vertical mounting shaft is fixedly installed on the guide wheel pushing plate, and a second guide wheel that is rotatably mounted on the vertical mounting shaft and cooperates with the pushing groove.
[0014] The present invention is further configured such that the lifting control component includes a support plate, a lifting control cylinder coaxially fixed on the top of the support plate, two covering grooves opposite each other on the periphery of the lifting control cylinder, a guide wheel rollingly engaging in the corresponding covering groove, and a locking rod corresponding to the mounting hole fixed at the bottom of the support plate, the locking rod being inserted into the corresponding mounting hole and fixed by a nut.
[0015] The invention is further configured such that two sets of sealing plates are symmetrically fixed on the top of the ball lamp carrier, each set of sealing plates is symmetrically fixed on both sides of the mounting groove, the sealing plates slide against the inner wall of the protective cover, and the surface of the sealing plates is provided with a plurality of convection holes I. The protective cover is provided with convection holes II on both opposite sides, which are adapted to the convection holes I. When the protective cover is in the closed state, the convection holes II and the convection holes I are misaligned. When the protective cover is in the open state, the convection holes II and the convection holes I are interconnected.
[0016] The present invention has the following beneficial effects: 1. The present invention slides a protective cover on the ball light carrier, and sets a sloping side on one side of the opening end of the protective cover with the same tilt angle as the end sealing plate. At the same time, the end sealing plate is slidably set inside the inclined guide frame. When there is thunderstorm or other weather that is not suitable for outdoor sports on the ball field, the horizontal movement of the protective cover is controlled so that its sloping side is in close contact with the surface of the end sealing plate. Through the combined action of the protective cover and the end sealing plate, the LED light body is fully enclosed for protection, thereby effectively avoiding the adverse effects of severe weather on the LED light body.
[0017] This invention controls the horizontal push drive seat and the lifting control cylinder to rotate 90° counterclockwise synchronously via a power motor. During the 90° counterclockwise rotation of the horizontal push drive seat, the guide wheel push part drives the two protective covers to move closer to each other, causing the inclined side of the protective cover to gradually detach from the end sealing plate. During the 90° counterclockwise rotation of the lifting control cylinder, under the limiting and guiding effect of the covering channel on the guide wheel, the two oppositely arranged lifting rods are gradually lifted. Under the action of the lifting rods, the end sealing components on both sides gradually move upward along the inclined guide frame, causing the end sealing components to detach from the protective cover and move above the LED lamp body. In this way, a single power source controls the synchronous drive of different motion processes, which not only reduces the equipment manufacturing cost but also improves the overall drive efficiency.
[0018] During the upward or downward movement of the control end-sealing assembly along the inclined guide frame, the lamp surface brush on the end-sealing plate can achieve full contact with the lamp surface of the LED lamp body, thereby cleaning the lamp surface of the LED lamp body. This ensures that the lighting effect of the LED lamp body is not affected by dust accumulation or insect contamination.
[0019] When the inclined side of the protective cover is in contact with the surface of the end cap, the first convection hole and the second convection hole at the corresponding position are misaligned, ensuring that rainwater and other impurities cannot enter the inside of the protective cover along the first and second convection holes. When the inclined side of the protective cover is completely separated from the end cap, the first convection hole and the second convection hole at the corresponding position are aligned and connected. In this way, air convection inside the protective cover can be achieved through the first and second convection holes on opposite sides, which is beneficial for heat dissipation of each LED lamp body.

Detailed Implementation
[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Example 1, please refer to Figures 1-11 This invention relates to an LED energy-saving stadium light, comprising a stadium light frame 1, an LED light body 2, a lampshade assembly 3, an end-sealing assembly 4, and an opening / closing control mechanism 5. The stadium light frame 1 includes an inclined guide section and guide wheel lifting sections corresponding to the inclined guide sections. The LED light bodies 2 are mounted on the top of the stadium light frame 1, with each LED light body 2 corresponding to one inclined guide section and one guide wheel lifting section. The lampshade assembly 3 is slidably mounted on the stadium light frame 1 and used to cover the LED light bodies 2. The end-sealing assembly 4 is slidably mounted on the inclined guide section and used to seal the inclined opening of the lampshade assembly 3; the end-sealing assembly 4 and the guide wheel lifting section slide horizontally together. The opening / closing control mechanism 5 consists of an opening / closing power assembly 6 and a lifting control assembly 7 that rotates synchronously with the opening / closing power assembly 6. A guide wheel pushing section 8 is mounted on one side of the lampshade assembly 3; the guide wheel pushing section 8 and the opening / closing power assembly 6 are connected via a guide groove, and the lifting control assembly 7 and the guide wheel lifting section are connected via a guide groove.
[0035] In this embodiment of the invention, such as Figure 5 and Figure 6As shown, the spherical lamp frame 1 also includes a spherical lamp carrier 9. An electrical control box 10 is fixed at the center of the bottom of the spherical lamp carrier 9. A fitting ring seat 11 is fixed at the bottom of the electrical control box 10. The fitting ring seat 11 is fixedly installed on the top of the lamp post by bolts and fasteners, thus achieving a stable installation of the entire spherical lamp frame 1 on the top of the lamp post. The top of the spherical lamp carrier 9 is provided with a mounting groove 12 for installing the LED lamp body 2. The mounting groove 12 can be specifically designed according to the shape and size of the base at the bottom of the LED lamp body 2 (in conjunction with bolts and fasteners for reinforcement). Of course, the LED lamp body 2 can also be directly and stably installed on the top of the spherical lamp carrier 9 by bolts and fasteners. The lamp surface (i.e., the light-emitting surface) of the LED lamp body 2 extends out of the spherical lamp carrier 9 (e.g., the light-emitting surface). Figure 4 As shown, this positional design ensures that the LED lamp body 2 can provide normal illumination, so that the open lampshade assembly 3 and the spherical lamp frame 1 will not interfere with the normal illumination of the LED lamp body 2.
[0036] Furthermore, the inclined guide section consists of a fixedly connected inclined guide frame 13 and a support frame 14 (it should be noted that the inclined guide frame 13 is parallel to the light-emitting surface of the LED lamp body 2). The support frame 14 is fixed between the electrical control box 10, the inclined guide frame 13, and the spherical lamp carrier 9. An L-shaped conduit 15 extending downwards is installed on the top of the spherical lamp carrier 9. It should be noted that a sealed door is detachably installed on the opening side of the electrical control box 10 (this sealed door is prior art and therefore not shown in the figure). The support frame 14 can be connected to the electrical control box 10 and the spherical lamp carrier 9 by welding. The inclined guide frame 13 has limiting channels on both inner sidewalls, which extend along the length of the inclined guide frame 13 (e.g., ...). Figure 6 (as shown), to ensure that the end cap assembly 4 is stably placed inside the inclined guide frame 13.
[0037] In this embodiment of the invention, such as Figure 6 As shown, the guide wheel lifting part includes a lifting seat 16 located above the ball lamp carrier 9. A guide rod 17 that slides through the ball lamp carrier 9 is fixed at the bottom of the lifting seat 16. In this embodiment, two guide rods 17 can be symmetrically arranged and pass through the ball lamp carrier 9 to ensure the stability of the entire guide wheel lifting part during the lifting and lowering process. A lifting rod 18 is horizontally slidably provided on the lifting seat 16. A guide wheel 19 is rotatably installed on the end of the lifting rod 18 near the opening and closing control mechanism 5. It should be noted that the installation process of the guide wheel lifting part on the ball lamp carrier 9 is as follows: first, the guide rod 17 on the lifting seat 16 is passed through the through hole at the top of the ball lamp carrier 9, and then the lifting rod 18 with the guide wheel 19 installed is horizontally passed through the lifting seat 16. After the position is adjusted, the installation of the entire guide wheel lifting part on the ball lamp carrier 9 is completed.
[0038] In this embodiment of the invention, such as Figure 1 , Figure 2 and Figure 7As shown, the lampshade assembly 3 includes a protective cover 20. One side of the inclined surface of the protective cover 20 is an open structure. On the side of the protective cover 20 opposite to the inclined surface, there is a U-shaped opening 21 that is adapted to the ball lamp carrier 9. Above the U-shaped opening 21, there is a connecting plate 22 that is fixed to the protective cover 20. It should be noted that the setting of the U-shaped opening 21 ensures that the protective cover 20 is smoothly fitted onto the ball lamp carrier 9 and can drive the protective cover 20 to slide horizontally along the ball lamp carrier 9. The inclination angle of the inclined surface of the protective cover 20 is the same as the inclination angle of the inclined guide frame 13.
[0039] In this embodiment of the invention, such as Figure 3 , Figure 4 and Figure 8 As shown, the end-sealing assembly 4 includes an end-sealing plate 23 slidably disposed within the inclined guide frame 13. The end-sealing plate 23 has the same inclination angle as the inclined guide frame 13. A horizontally arranged L-shaped support plate 24 is fixed to the top of the end-sealing plate 23. A positioning tube 25 is fixed through one side of the L-shaped support plate 24. The positioning tube 25 is slidably sleeved on the lifting rod 18 and connected by fasteners. That is, firstly, the guide rod 17 on the lifting seat 16 passes through the through hole at the top of the ball lamp carrier 9, and then the lifting rod 18 with the guide wheel 19 installed is horizontally passed through the lifting seat 16. After the position is adjusted, the lifting rod 18 and the positioning tube 25 are fixedly connected by screw fasteners. A lamp surface brush 26 is provided below the L-shaped support plate 24 and is fixedly installed with the end-sealing plate 23. The lamp surface brush 26 is used to clean the lamp surface of the LED lamp body 2.
[0040] like Figure 1 and Figure 2 As shown, when the LED lamp body 2 is in a fully enclosed protective state, the protective cover 20 is at the furthest position from the electrical control box 10. At this time, the inclined side of the protective cover 20 is attached to the surface of the end sealing plate 23, and the entire end sealing assembly 4 is supported by the lifting rod 18. At this time, the LED lamp body 2 is in a fully enclosed environment, which can effectively avoid the adverse effects of severe weather such as thunderstorms on the LED lamp body 2 and achieve a good protective effect.
[0041] like Figure 3 and Figure 4 As shown, when the LED lamp body 2 is in the fully open working state, the protective cover 20 is in the closest position to the electrical control box 10. At this time, the inclined side of the protective cover 20 is completely separated from the end sealing plate 23, and the lighting end of the LED lamp body 2 is fully exposed to the outside for nighttime lighting. The entire end sealing assembly 4 is in the top position of the inclined guide frame 13 under the action of the lifting rod 18. The end sealing assembly 4 is completely above the protective cover 20 without interfering with the normal lighting of the LED lamp body 2. During the movement of the end sealing assembly 4 along the inclined guide frame 13, the lamp surface of the LED lamp body 2 can be cleaned by the lamp surface brush 26.
[0042] Example 2, based on Example 1, such as Figure 1 and Figure 9 As shown, the opening and closing power assembly 6 includes a power motor 27 installed in the electrical control box 10 (this installation method is existing technology and will not be described in detail). The output shaft of the power motor 27 passes through the ball lamp carrier 9 and is connected to a push drive seat 28 (the power motor 27 is a small-sized motor). The top of the push drive seat 28 is provided with a push channel 29 corresponding to the push section 8 of the guide wheel (the push channel 29 is a through structure). The top of the push drive seat 28 is provided with a mounting hole 30. The push section 8 of the guide wheel and the push drive seat 28 are driven by the push channel 29. That is, during the process of the push drive seat 28 rotating 90° by the power motor 27, the two push sections 8 of the guide wheel move closer or further apart through the cooperation of the push channel 29 and the push section 8 of the guide wheel.
[0043] In this embodiment of the invention, such as Figure 2 and Figure 10 As shown, the guide wheel pushing part 8 includes a guide wheel pushing plate 31 fixed to the top of the connecting plate 22 by fasteners. A vertical mounting shaft 32 is fixedly installed on the guide wheel pushing plate 31. A guide wheel 33 is rotatably mounted on the vertical mounting shaft 32 and engages with the pushing groove 29. It should be noted that the guide wheel 33 is rolled in the pushing groove 29. During the process of controlling the rotation of the pushing drive seat 28, each guide wheel 33 always rolls along the pushing groove 29.
[0044] In this embodiment of the invention, such as Figure 3 and Figure 11 As shown, the lifting control assembly 7 includes a support plate 34. A lifting control cylinder 35, coaxial with the support plate 34, is fixed to the top of the support plate 34. Two covering channels 36 are arranged opposite each other on the circumferential side of the lifting control cylinder 35 (that is, the covering channels 36 are arranged along the circumferential side of the lifting control cylinder 35 and gradually extend upward). The guide wheel 19 rolls in the corresponding covering channel 36. During the rotation of the control push drive seat 28, the lifting control cylinder 35 rotates synchronously and in the same direction with the push drive seat 28. The guide wheel 19 always rolls along the covering channel 36. A locking rod 37 corresponding to the mounting hole 30 is fixed to the bottom of the support plate 34. The locking rod 37 is inserted into the corresponding mounting hole 30 and fixed by a nut. This installation method can realize the detachable connection of the lifting control assembly 7 on the push drive seat 28.
[0045] The entire installation process for LED energy-saving stadium lights is as follows: The necessary accessories are transported to the vicinity of the top of the light pole by a crane with guardrails. The cable terminals arranged inside the light pole are placed inside the electrical control box 10 along the sleeve ring seat 11. One cable terminal is connected to the wiring port of the power motor 27, and the other two cable terminals are respectively passed out from both sides of the electrical control box 10. After the sleeve ring seat 11 is fixed to the top of the light pole with bolts and fasteners, the cable terminals are passed from bottom to top through the L-shaped conduit 15 and connected to the LED light body 2 installed on the top of the ball light carrier 9. The conductive connection of the other LED light body 2 is completed in the same way.
[0046] Then, align the U-shaped opening 21 on the protective cover 20 with the ball lamp carrier 9, and horizontally slip it onto the ball lamp carrier 9 (at this time, the protective cover 20 is slipped onto the L-shaped conduit 15; specifically, the protective cover 20 has an insertion hole on the side near the U-shaped opening 21 that matches the horizontal section of the L-shaped conduit 15, such as...). Figure 4 As shown, at this time, the position of the protective cover 20 will not be affected by the movement interference of the bending section of the L-shaped conduit 15. Then, the guide wheel 23 on the guide wheel push part 8 is fitted into the push channel 29. The position of the connecting plate 22 on the protective cover 20 is adjusted, and the guide wheel push part 8 is fixed to the top of the connecting plate 22 with bolt fasteners. Next, the guide rod 17 on the lifting seat 16 is passed through the through hole at the top of the ball light carrier 9. Then, the lifting rod 18 with the guide wheel 19 is installed is passed horizontally through the lifting seat 16 and the positioning tube 25 in sequence. After the lifting control component 7 is fixedly installed on the top of the push drive seat 28, the circumferential position of the lifting control cylinder 35 is adjusted so that the bottom of the covering channel 36 is aligned with the direction of the lifting rod 18. Then, the position of the lifting rod 18 is adjusted until the guide wheel 19 on it is fully fitted into the covering channel 36. Finally, the lifting rod 18 and the positioning tube 25 are fixedly connected with screw fasteners. At this time, the entire LED energy-saving ball light is in the following state. Figure 1 and Figure 2 As shown, the guide wheel 19 is located at the bottom of the corresponding covering channel 36. Under the support of the lifting rod 18, the L-shaped support plate 24 is attached to the top of the protective cover 20. The inclined side of the protective cover 20 just abuts against the surface of the end sealing plate 23. At this time, each LED lamp body 2 is in a fully enclosed environment to achieve protection.
[0047] like Figure 3The arrow indicates the rotation direction (counterclockwise) of the lifting control component 7. In normal weather conditions (excluding thunderstorms), the power motor 27 controls the horizontal drive seat 28 and the lifting control cylinder 35 to rotate 90° counterclockwise. During this rotation, the horizontal drive seat 28, under the limiting and guiding effect of the horizontal drive channel 29 on the guide wheels 33, causes the two opposing guide wheel horizontal push parts 8 to move closer together, pulling the two protective covers 20 closer together. This causes the inclined side of the protective cover 20 to gradually detach from the end sealing plate 23. After the horizontal drive seat 28 completes its 90° counterclockwise rotation, the protective cover 20 releases its sealing protection of the LED lamp body 2's lighting end, while the lifting control cylinder 35 rotates counterclockwise... During the 90° clockwise rotation, under the limiting and guiding action of the guide wheel 19 by the covering channel 36, the two opposing lifting rods 18 are gradually lifted. The end-sealing assemblies 4 on both sides gradually move upwards along the inclined guide frame 13 under the action of the lifting rods 18. After the lifting control cylinder 35 completes a 90° counterclockwise rotation, the entire end-sealing assembly 4 is positioned at the top of the inclined guide frame 13 under the action of the lifting rods 18. The end-sealing assembly 4 is completely above the protective cover 20 without interfering with the normal illumination of the LED lamp body 2, thus ensuring that each LED lamp body 2 can provide stadium lighting. During the upward or downward movement of the end-sealing assembly 4 along the inclined guide frame 13, the lamp surface brushes 26 on the end-sealing plate 23 clean the lamp surface of the LED lamp body 2 (e.g., ...). Figure 4 As shown, the lamp surface brush 26 can achieve flexible and close contact with the lamp surface during the movement process, and the length of the lamp surface brush 26 is greater than the diameter of the lamp surface, so as to achieve thorough cleaning of the lamp surface, thus ensuring better lighting effect of the LED lamp body 2.
[0048] Example 3, based on Examples 1 and 2, as follows: Figure 5 and Figure 6 As shown, two sets of sealing plates 38 are symmetrically fixed on the top of the ball lamp carrier 9. Each set of sealing plates 38 is symmetrically fixed on both sides of the mounting groove 12. The sealing plates 38 slide against the inner wall of the protective cover 20 (the structural design of the U-shaped opening 21 ensures that the protective cover 20 can be fitted onto the sealing plates 38 and the ball lamp carrier 9). The surface of the sealing plates 38 is provided with a number of convection holes 39. The protective cover 20 is provided with convection holes 40 on both sides that are adapted to the convection holes 39. When the protective cover 20 is in the closed state, the convection holes 40 and the convection holes 39 are misaligned. When the protective cover 20 is in the open state, the convection holes 40 and the convection holes 39 are connected to each other.
[0049] That is, when the inclined side of the protective cover 20 is in contact with the surface of the end sealing plate 23, the convection hole 39 and the corresponding convection hole 40 are misaligned, ensuring that rainwater and other impurities cannot enter the inner side of the protective cover 20 along the convection hole 39 and the convection hole 40 (e.g. Figure 1As shown, when the inclined side of the protective cover 20 is completely separated from the end cap 23 (i.e., at the farthest distance), the convection hole 39 is aligned and connected with the convection hole 40 at the corresponding position. In this way, air convection can be achieved inside the protective cover 20 through the convection holes 39 and 40 on opposite sides, which is beneficial for heat dissipation of each LED lamp body 2.
