[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] Example 1

[0024] This utility model provides an outdoor waterproof LED stadium light, such as... Figures 1 to 4 As shown, the outdoor waterproof LED stadium light includes a lamp post 1, a sliding base 2, and an LED lighting assembly 3. The lamp post 1 is fixedly installed on the ground to mount the light fixture at a suitable lighting height. The sliding base 2 is connected to the lamp post 1 to support the stadium light. The LED lighting assembly 3 includes a light fixture body 301, a waterproof groove 302, an LED bead plate 303, a reflector 304, a waterproof connector 305, a vent valve 306, a waterproof sealing strip 308, and a fixing base 313. The light fixture body 301 is connected to the sliding base 313 via the fixing base 313. The lamp body 301 has a waterproof groove 302 inside the base 2. The lamp bead plate 303 is located inside the lamp body 301. The reflector cup 304 is installed inside the lamp body 301 and is located directly above the lamp bead plate 303. The waterproof connector 305 and the vent valve 306 are both installed at the rear of the lamp body 301. The waterproof connector 305 is used to provide waterproof treatment for the power input line. The vent valve 306 is used to balance the air pressure inside the lamp body 301. The waterproof strip 308 is T-shaped and embedded in the waterproof groove 302.

[0025] In this embodiment, the lamp body 301 is also equipped with a driving power supply 307. The driving power supply 307 can convert the externally input electrical energy into voltage and current that are compatible with the lamp bead board 303, so as to provide stable power support to the lamp bead board 303. The bottom of the horizontal surface of the waterproof strip 308 is closely attached to the top of the waterproof groove 302 platform in the lamp body 301. The top of the waterproof strip 308 is pressed tightly by the protective glass 309. The back of the protective glass 309 is screen-printed black on one side, and the upper part corresponding to the lens is not screen-printed and does not block light. The screen-printed part of the protective glass 309 covers the driving power supply 307. This design can not only block the driving power supply 307 and other components that do not need to emit light, avoiding light leakage and interference, but also ensure that the light in the lens part can pass through freely to achieve a good lighting effect. At the same time, the black screen-printed part can also absorb some light, reduce glare and reflection, and improve the comfort and quality of lighting.

[0026] By embedding the waterproof strip 308 into the waterproof groove 302 and pressing the waterproof strip 308 tightly with the protective glass 309, the sealing effect of the lamp is achieved. At the same time, the protective glass 309 can be firmly installed inside the lamp body 301 with the help of the metal pressure plate 310. This simplifies the installation steps of the waterproof part of the lamp and allows for quick installation of the lamp without the need for welding.

[0027] In use, the operator uses an external power source connected to the lamp body 301 via a waterproof connector 305. The drive power supply 307 converts the external power into voltage and current compatible with the lamp bead board 303, supplying power to the lamp bead board 303. Then, the waterproof strip 308 is embedded into the waterproof groove 302, and the metal pressure plate 310 is inserted into the pressure plate groove 315, thereby pressing the protective glass 309 tightly against the top of the waterproof strip 308. Finally, the pressure plate screw 316 is used to thread the strip through the metal pressure plate 310 and install it into the lamp body 301, thus fixing the protective glass 309 inside the lamp body 301 and achieving a sealing effect for the lamp. The operation is simple and easy to disassemble.

[0028] It is worth noting that the waterproof sealing strip 308 is typically made of ethylene propylene diene monomer (EPDM) rubber or silicone rubber, possessing good elasticity and compression resilience. Under pressure, it can tightly fill gaps to ensure a sealing effect; it has strong chemical stability, is not easily corroded by rainwater, dust, or corrosive substances, and has a long service life. The waterproof sealing strip 308 is inserted into the waterproof groove 302 in a T-shape, with its bottom surface in close contact with the platform above the waterproof groove 302, forming a preliminary seal. The protective glass 309 covers the top of the waterproof sealing strip 308, and pressure is applied to the protective glass 309 by the metal pressure plate 310, causing the protective glass to... 309 presses the waterproof strip 308 tightly; at this time, the waterproof strip 308 undergoes elastic deformation due to pressure, completely filling the gap between the waterproof groove 302 and the protective glass 309, forming a triple tight fit of "strip-groove-glass", blocking the path of rainwater, dust and other impurities to enter the lamp; the waterproof connector 305 at the tail of the lamp body 301 seals the power cord to prevent water from entering at the cable connection point, and the vent valve 306 can balance the air pressure inside and outside the lamp body 301, avoiding the generation of condensation inside the LED lamp assembly 3 due to temperature difference or excessive air pressure that damages the sealing structure, further enhancing the waterproof performance of the LED lamp assembly 3.

[0029] To facilitate adjustment of the installation angle of LED lighting component 3, such as Figures 1 to 4 As shown, a rotating seat 311 is also installed at the end of the lamp body 301. The surface of the rotating seat 311 is marked with scale markings. The base of the rotating seat 311 has multiple through holes, corresponding to multiple threaded holes opened at the end of the lamp body 301. The rotating seat 311 can be detachably installed at the end of the lamp body 301 by means of eye bolts 312. A fixed seat 313 is also slidably installed inside the sliding seat 2. The side of the end of the fixed seat 313 is provided with arc teeth and threaded holes. The end of the rotating seat 311 is provided with arc teeth and fixed through holes, which can be connected to the fixed seat 313. The fixed seat 313 is the load-bearing base of the entire lamp. The end of the fixed seat 313 away from the rotating seat 311 is a flange edge. The side has threaded holes, which can be connected to the side cover plate 314 by threads. The side cover plate 314 is engraved with a base point mark, which points to the scale position on the surface of the rotating seat 311.

[0030] The rotating base 311 is fixedly installed at the end of the lamp body 301 by means of the eye bolt 312, and the arc tooth ends of the rotating base 311 and the fixed base 313 are connected to each other so that they can rotate relative to each other and adjust the angle. At the same time, the base point mark on the side cover plate 314 can point to the scale position on the surface of the rotating base 311, thereby enabling quick adjustment of the deflection angle of the lamp body 301. The illumination angle of the lamp can be adjusted without relying on complicated measuring tools or methods, making it suitable for more different installation environments and lighting needs.

[0031] The back of the lamp body 301 is also densely and evenly covered with fins 4. The design of the fins 4 can increase the contact area between the LED lamp assembly 3 and the outside air. When the LED stadium light is working, the lamp bead board 303 and the driver power supply 307 will continuously generate heat. This heat will be transferred to the housing of the lamp body 301. Through the large area fins 4 installed on the back of the lamp body 301, the generated heat can be quickly dissipated to the surroundings, effectively reducing the internal temperature of the lamp body 301. This prevents excessive heat accumulation inside the lamp body 301 from affecting the normal operation of the lamp bead board 303 and the driver power supply 307, thereby ensuring the luminous efficiency and stability of the lamp bead board 303, extending the service life of the driver power supply 307 and the entire lamp, and reducing maintenance and replacement costs.

[0032] Working principle: In actual use, the external power supply is connected to the lamp body 301 through the waterproof connector 305. The driving power supply 307 converts the input electrical energy into voltage and current that are compatible with the lamp bead board 303, providing a stable power supply to the lamp bead board 303. After the lamp bead board 303 is powered on, the light emitted is focused by the reflector cup 304 above, and then projected onto the field through the protective glass 309 to achieve the lighting function.

[0033] The installation process of the protective glass 309 is as follows: the waterproof strip 308 is embedded into the waterproof groove 302, and the bottom of the horizontal surface of the waterproof strip 308 is pressed against the top of the platform of the waterproof groove 302. The top of the waterproof strip 308 is then pressed down by the protective glass 309. Then, the metal pressure plate 310 is inserted into the pressure plate groove 315. The metal pressure plate 310 is fixedly installed in the pressure plate groove 315 by the pressure plate screw 316. Thus, the protective glass 309 can be firmly installed in the lamp body 301. At this time, the protective glass 309 and the waterproof strip 308 are in close contact with each other, which can achieve the sealing and waterproof effect of the lamp. The installation can be completed without welding, and the operation is simple and easy to disassemble and maintain.

[0034] Next, insert the fixing seat 313 into the slide seat 2, and fix the rotating seat 311 to the end of the lamp body 301 with the eye bolt 312. Then, fix the side cover plate 314 to the outside of the fixing seat 313 with screws. Align the fixing through holes and threaded holes of the rotating seat 311 and the fixing seat 313 with each other, and while rotating the rotating seat 311, observe the scale position indicated by the base point mark on the side cover plate 314. After the installation angle of the rotating seat 311 is determined, make the arc teeth of the rotating seat 311 and the fixing seat 313 mesh with each other and fix the rotating seat 311 and the fixing seat 313 to each other with screws. The installation operation of the LED lamp assembly 3 body can be completed. The rotating seat 311 and the fixing seat 313 are detachably connected by screws, which can further reduce the maintenance difficulty.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
