Description

Technical Field

[0001] This utility model belongs to the field of stadium lighting technology, specifically relating to a stepless limit and washable power stadium light. Background Technology

[0002] LED stadium lights are a common type of lighting fixture. To ensure lighting effects, they typically have a large lens installed at the front of the LED light-emitting surface. Examples include the multi-angle supplementary lighting stadium light ZL202421158784.6 and the anti-glare tennis court light with high vertical illuminance ZL202420467630.9. While these popular stadium lights can meet lighting needs, dust accumulation on the lens surface during long-term use can severely affect the light output of the fixture.

[0003] There is also a type of LED light with a simple arc groove mounting bracket, such as ZL202322262260.3. Although it can also ensure light output, when used at high altitudes, the light fixture vibrates in the air due to wind, causing the previously fixed illumination point to shift because the arc groove cannot lock 100%, thus affecting the effect of use.

[0004] The existing LED stadium lights have significant technical shortcomings, making them unsuitable for washing operations and unable to effectively reduce the vibration and misalignment of the lights during washing, thus limiting their applicability. Summary of the Invention

[0013] A further preferred embodiment is that the width of the C-shaped locking tab matches the width of the adjacent heat dissipation fins;

[0014] The C-shaped locking tab is connected to the heat sink and is limited by the side wall of the adjacent heat sink fins.

[0015] A further preferred embodiment is that the number of mounting screw holes on each edge of the radiator is three or four.

[0016] A further preferred embodiment is that the connecting bracket is provided with a central tooth hole, and the connecting bracket is provided with a plurality of limiting tooth holes arranged circumferentially around the central hole;

[0017] Both ends of the n-shaped mounting bracket are provided with a central circular hole, and both ends of the n-shaped mounting bracket are provided with a limit circular hole and an arc-shaped adjustment slot hole circumferentially arranged with the central circular hole as the center.

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. Example 1

[0039] See Figures 1 to 7 As shown, a stepless, limit-adjustable, washable power stadium light includes a heat sink 2 with heat dissipation fins 1, an optical device 3 fixed to the bottom surface of the heat sink, an n-shaped groove 4 formed along the edge of the bottom surface of the heat sink, and a triangular waterproof protrusion 5 integrally formed on the top wall of the n-shaped groove. In this embodiment, the optical device includes a light-emitting unit, a lens body, and a waterproof ring; the light-emitting unit is combined with the lens body, and the waterproof ring is located at the connection between the lens body and the heat sink. The optical device and heat sink are conventional structures in the prior art, and are simply applied; therefore, they are not described in detail.

[0040] In this embodiment, a glass cover 6 is provided on the bottom surface of the heat sink. The bottom surface of the glass cover is close to the surface of the light source device, and its edge is fitted to the opening of the n-shaped groove. A sealing filling layer is provided at the connection between the n-shaped groove and the glass cover. The gap between the glass cover and the optical device is infinitesimally small, which can reduce the energy loss of light passing through the gap and ensure the lighting effect. The sealing filling layer includes a single foam layer, a stacked foam layer and a silicone rubber layer, or a double silicone rubber layer. Through the above structure, the sealing performance of the connection can be improved, so that the internal optical device will not be affected during rinsing.

[0041] In this embodiment, connecting brackets 7 are fixed to the symmetrical edges of the heat sink by screws, and an n-shaped mounting bracket 8 is provided between the two connecting brackets. The n-shaped mounting bracket is attached to the connecting brackets and rotatably connected by screws. This structure allows for stepless adjustment of the heat sink relative to the n-shaped mounting bracket, meeting the needs of different applications.

[0042] In this embodiment, a plurality of mounting screw holes 9 are integrally formed at the top edge of the radiator, and the mounting screw holes 9 are located between adjacent heat dissipation fins; a C-shaped locking piece 10 is provided between the radiator and the glass cover; during assembly, the bottom edge of the recessed area of ​​the C-shaped locking piece abuts against the bottom edge of the glass cover, and the top edge of the recessed area is attached to the top surface of the mounting screw holes 10 and fixed with screws. The width of the C-shaped locking piece matches the width of the adjacent heat dissipation fins; the C-shaped locking piece is connected to the radiator and limited by the side walls of the adjacent heat dissipation fins. This structure not only ensures the secure connection between the glass cover and the radiator, guaranteeing a stable connection, but also, because its width matches the width of the adjacent heat dissipation fins, the C-shaped locking piece can be limited by the heat dissipation fins, preventing vibration-induced displacement and improving the safety factor.

[0043] Furthermore, in this embodiment, the number of mounting screw holes on each edge of the heat sink is three or four. This ensures the smoothness and reliability of the connection;

[0044] Furthermore, in this embodiment, the connecting bracket is provided with a central threaded hole 11, and the connecting bracket is provided with a plurality of limiting threaded holes 12 arranged circumferentially around the central hole; both ends of the n-shaped mounting bracket are provided with central circular holes 13, and both ends of the n-shaped mounting bracket are provided with limiting circular holes 14 and arc-shaped adjustment slots 15 arranged circumferentially around the central circular holes; a locking screw is provided in the limiting circular holes or arc-shaped adjustment slots. Through the above structure, by cooperating with different limiting circular holes and limiting threaded holes and locking with screws, and by using the screw in the arc-shaped adjustment slot, stepless adjustment operation can be achieved, which can meet the usage needs of different situations and has strong applicability.

[0045] Moreover, in this embodiment, a light shield 16 is fixed to the light-emitting surface of the heat sink by screws.

Through the combination of the n-shaped groove, the glass cover, and the triangular water-stopping ridge, the waterproof performance can be effectively improved, facilitating the washing of the glass cover. This helps prevent dust accumulation on the glass cover surface from affecting the light emission effect, ensuring stable and effective use, and facilitating washing and maintenance. Furthermore, the n-shaped mounting bracket and the connecting bracket are fitted together and rotatably connected by a screw, thus enabling stepless limit adjustment, meeting the needs of different situations and expanding its applicability.

[0047] Furthermore, the top edge of the radiator has several integrally formed mounting screw holes, and a C-shaped locking piece is provided between the radiator and the glass cover. The C-shaped locking piece is connected to the radiator and limited by the side wall of the adjacent heat dissipation fins, which can prevent the lamp from vibrating and shifting during washing, improve the stability of the lamp during use, increase the safety factor of the lamp, and make it highly applicable. Example 2

[0048] See Figure 8 As shown, this embodiment is basically the same as Embodiment 1, except that: an expansion bracket 17 is provided on the heat sink; the expansion bracket includes a longitudinal expansion bracket 171 and a transverse expansion bracket 172. When adjacent heat sinks are joined, the expansion bracket is attached to the top edge of the two heat sinks and fixed to the mounting screw holes with screws. This allows for extended connections to meet the needs of different applications.
