Technical Field
[0001] This utility model relates to the field of lighting technology, specifically to a stadium lighting lamp with good lighting effect. Background Technology
[0002] The lighting needs of sports venues such as tennis courts and peak courts are becoming increasingly diverse and specialized, but existing lighting technologies have limitations in many aspects, for the following reasons: From a technical perspective, early stadium lighting mostly used traditional light sources such as high-pressure sodium lamps, which suffered from low energy efficiency, poor color rendering, and short lifespan. Although LED lighting technology was gradually applied to stadiums later, most products still followed the design logic of "general-purpose LED lamps" and were not designed for the special optical needs of stadiums. As a result, the visual comfort of athletes and the uniformity of illumination throughout the field were weak, leading to insufficient glare control and persistent problems with blind spots in lighting. From the perspective of scenario requirements, different types of sports fields—community recreation fields, amateur competition fields, and professional competition venues—have significantly different functional requirements for lighting: community sports fields need to balance "low energy consumption" and "long-term operation"; amateur competition fields need to balance "lighting brightness" and "cost control"; and professional competition venues need to meet the stringent requirements of "high-definition broadcasting" and "international competition standards." The "single-mode design" of traditional lighting fixtures cannot adapt to these differentiated scenarios, either causing energy waste or failing to meet the competitive or spectator experience.
[0003] In summary, the shortcomings of existing lighting technologies in terms of optical adaptability and scene compatibility create a prominent contradiction with the current development needs of professional and scenario-based stadium lighting. Therefore, it is necessary to design a professional stadium LED lighting fixture that can simultaneously solve problems such as glare, uneven illumination, and limited modes. Utility Model Content
[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a stadium lighting lamp with good lighting effect, solving the problems of glare, uneven lighting and limited lighting modes.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-8 This utility model provides a new technical solution: a stadium lighting lamp with good lighting effect, including a main body 1, a heat sink 12 connected to the main body 1 through a heat sink fixing plate 11; an LED light panel 13 is fixedly connected to the heat sink 12 through a fixing lamp panel screw 14, the LED light panel 13 includes three independently controlled LED modules, corresponding to leisure mode, entertainment mode and competition mode respectively; the outer side of the LED light panel 13 is covered with an arc-shaped frosted PC lampshade 15, the PC lampshade 15 is hinged to one end of the main body 1 through a hinge 16 and a rivet 17; the top of the main body 1 is connected to an adjustable angle mounting bracket (including mounting bracket A2 and mounting bracket B3) through a fixing bracket screw 7, an M8 screw 5, an M8 nut 6 and a spring 4; a wireless Bluetooth controller 8 and a power driver 9 are also provided inside the main body 1, the power driver 9 is electrically connected to the LED light panel 13, and the wireless Bluetooth controller 8 is electrically connected to the power driver 9; a wire outlet mounting flap 10 is provided at one end of the main body 1; The LED light panel 13 adopts a 30-50-70 degree three-sided projection design, which, together with the arc-shaped frosted PC lampshade 15, achieves a uniform light distribution of 180 degrees. The mounting brackets (mounting bracket A2, mounting bracket B3) can be adjusted upward or downward by loosening the M8 screw 5 and the fixing bracket screw 7 to adapt to the beam direction requirements of different scenarios; The main body 1 adopts a fully open design. The power driver 9 and LED light panel 13 can be repaired and replaced on-site by opening the PC light cover 15. The repair time is no more than 5 minutes.
[0016] Furthermore, before using this device, installation preparation should be carried out. The number of lights to be installed (usually 4-6 lights per side) and the installation height (recommended 6-8 meters) need to be determined based on the site dimensions (e.g., a standard tennis court is 23.77 meters long and 8.23 meters wide). At the same time, check that the main body 1, mounting bracket A2, mounting bracket B3, and other components are intact. Power cords should also be pre-installed through the outlet holes of the cable mounting tab 10 to avoid cable tangling during subsequent installation. After completing the installation preparation, proceed to the installation and fixing stage. First, use mounting brackets A2 and B3 to hang the lights on the pre-set light poles or ceiling mounting bases, and initially fix them using the fixing bracket screws 7. Then, use expansion screws through the mounting holes of the cable mounting tab 10 to further fix the lights, ensuring a firm installation and a wind resistance level of at least level 10. After installation and fixing, angle adjustment is required. First, loosen the M8 screws 5 and the fixing bracket screws 7, and adjust the bracket angle according to the simulated lighting diagram of the site based on the light distribution curve of the lights. For the end line area, adjust the angle downwards by 15°-20° to ensure the beam covers the blind spots of the end line. For the midfield area, adjust the angle downwards by 5°-10° to avoid light overlap causing uneven brightness. After adjustment, tighten the screws. At this time, spring 4 will help lock the angle to prevent loosening later. After the angle adjustment is completed, perform electrical connection and functional testing. Connect the power cord to the input terminal of the power driver 9 through the outgoing cable mounting tab 10. After powering on, connect to the wireless Bluetooth controller 8 through the mobile APP (the pairing code "123456" needs to be entered for the first connection) and test the switching function of the three modes in sequence. Focus on checking whether the three modules of the LED light panel 13 can be turned on and off normally, whether the diffusion effect of the PC lamp cover 15 is glare-free, and whether the temperature rise of the heat sink 12 is controlled within the safe range of ≤60℃. After the functional test is passed, the lights enter the daily operation phase. Site managers can use the APP to set automatic mode switching according to time periods (e.g., activate leisure mode from 9:00 AM to 5:00 PM, and manually switch modes from 5:00 PM to 10:00 PM according to the type of activity that day). During operation, the wireless Bluetooth controller 8 will monitor the current and voltage parameters of the power driver 9 in real time. Once an abnormality occurs, an alarm message will be immediately pushed to the manager's mobile phone for timely handling. Regular maintenance is also required during daily operation. During maintenance, the PC lamp cover 15 can be opened by hinge 16 to clean the dust on the surface of the LED light board 13 to avoid affecting the lighting brightness. If the power driver 9 fails, it can be replaced by simply disconnecting the power and loosening its fixing screws. If a module of the LED light board 13 is damaged, the light board can be removed by fixing the light board screws 14 and the corresponding module can be replaced. The entire process does not require disassembling the main body 1, and the maintenance time can be controlled within 5 minutes.
[0017] Main body 1 and heat dissipation system: The main body 1 is an integral aluminum alloy structure and is the physical load-bearing core of the entire lamp; the heat sink 12 is connected to the internal side wall of the main body 1 through the heat sink fixing plate 11. Its dense heat dissipation fins can quickly absorb the heat generated by the LED light panel 13 and dissipate it to the outside, ensuring the thermal stability of the lamp under high power operation.
[0018] LED light panel 13 and optical adjustment: LED light panel 13 is fastened to the heat dissipation fins of heat sink 12 by fixing light panel screws 14. The light panel integrates three independent LED modules of 30°, 50° and 70° to achieve 180° full-area light coverage. The arc-shaped frosted PC lampshade 15 is hinged to one end of the main body 1 by hinges 16 and rivets 17. It can eliminate glare by diffusion and can be quickly opened to expose the internal components during maintenance.
[0019] Installation and Angle Adjustment: Mounting brackets A2 and B3 are connected to the top of the main body 1 via fixing bracket screws 7, M8 screws 5, M8 nuts 6 and springs 4; springs 4 serve as buffers and assist in angle adjustment. Construction workers can loosen M8 screws 5 and fixing bracket screws 7 to adjust the mounting brackets up or down to the target angle, change the direction of the light beam projection, and ensure the uniformity of lighting for stadiums of different sizes.
[0020] Electronic control mode switching: The wireless Bluetooth controller 8 and the power driver 9 are built into the electronic control cavity of the main body 1. The power driver 9 provides constant current power to the LED light board 13. The wireless Bluetooth controller 8 receives external commands (such as mobile APP, Bluetooth remote control) through Bluetooth signal to realize the independent opening and closing of the three LED modules, and then switches between "leisure mode low brightness, single module operation, entertainment mode medium brightness, dual module operation, competition mode high brightness, and all three modules in operation".
[0021] Outgoing cable and installation structure: The outgoing cable mounting flap 10 is welded to one end of the side wall of the main body 1. The outgoing cable hole and mounting hole on it can organize the power cord and fix the lamp to the lamp post or ceiling, simplifying the installation process.
[0022] Featuring a side-emitting design with a curved frosted PC lampshade 15, the light is diffused and indirectly projected onto the field, effectively eliminating glare. The UGR value is as low as 13-19 (depending on the mode), providing a comfortable visual environment for athletes and spectators. The LED light panel 13 adopts a 30-50-70 degree three-sided projection design, combined with an adjustable-angle mounting bracket, to achieve 180-degree uniform illumination across the entire field, covering every corner with uniform illumination and no blind spots. It integrates three independently controlled LED modules, which can be switched between leisure, entertainment, and competition modes via a wireless Bluetooth controller 8. The brightness and light distribution can be adjusted according to different scenarios, with multi-mode adaptability and flexible scene selection. The fully open structure allows the PC lampshade 15 to be quickly opened and closed via hinge 16. The power driver 9 and LED modules can be quickly replaced on-site, with maintenance time not exceeding 5 minutes, improving efficiency through a quick-repair design.
[0023] Example 1: Leisure Mode: The applicable scenario is a non-standard tennis court of approximately 600㎡ within a community, open to residents from 9:00 AM to 5:00 PM daily, primarily for the elderly, children, and tennis beginners. It is used for walking, simple ball-juggling practice, and parent-child interactive activities. No high-intensity lighting is required. During operation, the venue administrator can activate the mode in two ways: First, open the dedicated management mobile app, click the "Leisure Mode" icon on the "Court Lighting" interface, and the wireless Bluetooth controller 8 will receive the command within 3 seconds and provide a "Switched" message; second, if the app signal is weak, press the physical emergency button on the side of the main unit 1. This hidden button requires a special key to open and will also trigger mode switching. After activation, the power driver 9 only supplies power to the 30° projection angle module in the LED light panel 13. Each module has a power of 30W, operating in the center area of the court. The area is approximately 200 square meters, corresponding to the main activity area of residents. The average illuminance is stable at 80-100 lux, and the illuminance in the edge area is 30-50 lux, which meets the basic safety visibility requirements. During this period, the curved frosted PC lampshade 15 will diffuse the LED light 360°. The measured glare value (UGR) is ≤19. Even when residents face the lamp when the light gradually dims from 16:00 to 17:00 in the evening, they will not experience eye pain or blurred vision. At the same time, the heat sink 12 operates as a single module, and the temperature rise is controlled at 35-40℃. It can maintain stability without additional heat dissipation measures. In this mode, the power consumption of a single lamp is about 0.24 kWh for 8 hours of operation per day, which is more than 60% more energy-efficient than traditional lamps. The independent operation design of the module can avoid unnecessary energy waste and is fully adapted to the low-intensity, long-term leisure needs of the community.
[0024] Example 2: Entertainment Mode: For a corporate tennis team tournament with 16 participants, the event will be held from 7:00 PM to 9:00 PM on a standard tennis court. The tournament must be of moderate intensity, requiring players to clearly judge the trajectory of the ball and avoid injuries. Fifteen minutes before the match, the organizers must complete two preparations: First, via Bluetooth remote control: pair with the wireless Bluetooth controller 8 (effective distance 50 meters), press the "Entertainment Mode" button, and simultaneously observe the indicator lights on the LED light panel 13. The green indicator lights corresponding to the 30° and 50° modules should light up, indicating that both modules are activated. Second, check that the PC lampshade 15 is tightly closed to prevent light leakage from affecting the viewing experience. During operation, the total power of the two modules is 60W, and the power driver 9 outputs a constant current of 1.2A to ensure stable brightness and no flicker in both modules. The 30° module's beam should be concentrated and cover the center of the field. The 50° module's beam extends from the court area (220-250 lux) to the sidelines and service area (180-200 lux), creating a superposition in the net area, resulting in an illumination of 250-280 lux in this key area. Players can clearly capture the ball's spin trajectory when volleying at the net. In addition, the angles of mounting brackets A2 and B3 have been pre-adjusted to 12°-15° downwards, preventing the beam from shining directly on the player's face. Combined with the frosted effect of the PC lampshade 15, the glare value (UGR) is ≤16, ensuring that even if players tilt their heads back to receive high balls, they will not experience temporary blindness. If temporary brightness adjustments are needed during the match, the output power of the power driver 9 can be finely adjusted via the APP, allowing for stepless adjustment within the range of 10%-100% without interrupting the match, thus meeting the flexible adjustment needs of amateur matches.
[0025] Example 3: Competition Mode: The tournament, a 3-day regional open competition using professional tennis courts that meet International Tennis Federation (ITF) standards, will be held from 18:00 to 22:00 on the final day. It must meet the triple requirements of competitive judgment, spectator viewing, and high-definition broadcasting (1080P / 60fps). Thirty minutes before the match, technicians will conduct professional adjustments: first, using a lux meter to calibrate the brightness at 20 test points throughout the court (including key locations such as the baselines, sidelines, service area, and midcourt), ensuring that the LED light panels maintain a brightness of 30°+50°+70°. When all three modules are fully operational, the average illuminance across the court reaches 500-600 lux, the minimum illuminance / average illuminance ratio is ≥0.8, and the vertical illuminance (in the direction of the players' line of sight) is ≥300 lux (meeting the requirements for vertical illuminance in broadcasting). Then, through the backend system of the wireless Bluetooth controller 8, the color temperature is locked at 5000K (close to natural light, restoring the white and yellow hues of tennis balls and the colors of the players' clothing), and the color rendering index (Ra) is adjusted to ≥90 to ensure accurate and unbiased colors in the broadcast image. During operation, the total power of the three modules... With a power consumption of 90W, the power driver 9 adopts a dual-backup design. If the main driver fails, the backup driver will automatically switch within 0.5 seconds to avoid interruption of the event. The heat sink 12, operating at full load, will quickly dissipate heat through the aluminum alloy shell of the main body 1. After 3 hours of continuous operation, the temperature rise is ≤55℃, far below the safety threshold (60℃), ensuring that the brightness of the LED light panel 13 does not decrease. In addition, the angle of the mounting bracket A2 and mounting bracket B3 is fixed at 8°-12° downward, and the beam of the 70° module accurately covers the corners of the field (the lighting dead spots that are prone to occur in traditional lighting fixtures), making the entire field free of dark areas. The frosted density of the PC lampshade 15 has been specially treated to eliminate glare (UGR≤13) without affecting the light penetration, meeting the needs of the audience to watch the game clearly from the stands. After the event, technicians can export the operating data (such as the running time of each module, power parameters, etc.) through the wireless Bluetooth controller 8 to provide a basis for subsequent maintenance, fully adapting to the high stability, high image quality, and high security requirements of professional events.
