Technical Field
[0001] This utility model relates to the field of professional sports lighting technology, and more specifically, to an LED lighting device for badminton courts. Background Technology
[0002] The current mainstream lighting equipment for badminton courts has three main shortcomings:
[0003] Low heat dissipation efficiency: The concentrated arrangement of high-power LED beads leads to heat accumulation, increasing the weight of traditional heat sinks by more than 30% and accelerating light decay;
[0004] Optical interference: The anti-glare structure blocks the effective light, resulting in a measured illuminance loss of 15-20%, and is also prone to high-frequency flicker;
[0005] Structural redundancy: The multi-component assembly design increases assembly time by more than 50%, and the separation of the frame from the heat sink weakens the shock resistance;
[0006] Therefore, an LED lighting device for badminton courts is proposed to address the above problems. Utility Model Content
[0007] In order to overcome the above-mentioned defects of the prior art, the present invention provides an LED lighting device for badminton courts to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution: an LED lighting device for badminton courts, comprising two sets of fixed brackets fixed to the top, characterized in that angle adjustment brackets are connected to the surfaces of the two sets of fixed brackets, and a fixing screw is provided between the angle adjustment brackets and the fixed brackets; a heat sink is connected to the bottom of the angle adjustment brackets; a base plate is provided below the heat sink; a PC end cap is provided on the surface of the base plate; PC extruded boards are provided on both sides of the PC end caps; a PC board is provided between the PC extruded boards and the bottom of the base plate; and an anti-glare grid plate is provided at the bottom of the PC board.
[0009] Preferably, the angle adjustment bracket, the heat sink, and the substrate are all provided with threaded holes at corresponding positions, and a fixing screw is provided between the corresponding threaded holes.
[0010] Preferably, the fixed bracket has two sets of through holes on its surface, and the angle adjustment bracket has multiple sets of through holes on its surface. The through holes in the middle part of the fixed bracket and the angle adjustment bracket are connected by a fixing screw.

[0011] Preferably, the substrate is an aluminum substrate with a thermal conductivity ≥180W / m·K and a copper foil thickness of 18µm.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] Compared with existing technologies, this utility model reduces the amount of aluminum material used by 40% through the above-mentioned structure, compresses the assembly process of the production line from 27 steps to 11 steps, and reduces maintenance costs by 60%. Modular assembly: the combination of screw fixing and plug-in grooves reduces the number of structural parts and lowers assembly costs.

The grille and frame are connected by dovetail grooves, reducing the installation time from 15 seconds to 3 seconds. The 25° acute angle grille design makes the UGR glare index <19.
