Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED floodlight technology, and in particular to a fixed explosion-proof LED floodlight. Background Technology
[0002] A floodlight is a lighting fixture that provides illumination to a surface higher than the surrounding environment; it is also known as a spotlight. Typically, it can be aimed in any direction and has a structure unaffected by weather conditions. It is mainly used for large-area work sites, building outlines, stadiums, overpasses, monuments, parks, and flower beds. Therefore, almost all large-area outdoor lighting fixtures can be considered floodlights. Floodlights have varying beam angles, ranging from 0° to 180°, with those having particularly narrow beams being called searchlights. However, these explosion-proof floodlights have poor heat dissipation, and their explosion-proof performance is inadequate in the event of an LED explosion. Utility Model Content

Each mounting area has a pin assembly near the bottom. The LED light board has a socket near the bottom that matches the pin assembly. The LED light board has multiple square plates, each square plate having two rows of LED beads. Each square plate has fixing bolt holes. The fixed bolt holes are fixed to the heat dissipation back plate by fixing bolts. Each mounting area on the front side of the heat dissipation back plate has mounting bolt holes around its perimeter. The front cover is a metal frame with a transparent glass plate installed in the middle of the metal frame.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0018] Reference Figure 1-3 A fixed explosion-proof LED floodlight includes a heat dissipation backplate 1, a circuit tube 3, a front cover, and an LED light panel 7. The heat dissipation backplate 1 is a metal plate with heat dissipation fins 11 on its back. Multiple mounting areas are arranged in a row on the front sidewall of the heat dissipation backplate 1. Each mounting area has a pin assembly 8 near its bottom. The LED light panel 7 has a socket near its bottom that matches the pin assembly 8. The LED light panel 71 has multiple square plates 71, each with two rows of LED beads. Each square plate 71 has fixing bolt holes 72. The hole 72 is fixed to the heat dissipation backplate 1 by fixing bolts. Each mounting area on the front side of the heat dissipation backplate 1 has mounting bolt holes around its perimeter. The front cover is surrounded by a metal frame 5, and a transparent glass plate 6 is installed in the middle of the metal frame 5. The front cover is fastened onto the mounting area, and the bolt holes on the front cover are matched with the mounting bolt holes and tightened with bolts. The heat dissipation backplate 1 is equipped with U-shaped brackets 2 on both sides by adjusting bolts 21. The back of the heat dissipation backplate 1 is provided with an integrated circuit cylinder 3 near the bottom. One end of the circuit cylinder 3 has a cylinder cover 4, and the cylinder cover 4 is fixed to the circuit cylinder 3 by multiple bolts around its perimeter.
[0019] The heat dissipation backplate 1 is integrally die-cast into a metal plate (aluminum alloy), and the surface is sprayed with insulating and corrosion-resistant paint. During lighting, the heat inside the front cover and the heat on the LED light board 7 are quickly absorbed by the heat dissipation backplate 1 and dissipated by the heat dissipation fins 11. Moreover, the heat dissipation backplate 1 has good explosion-proof performance. The entire LED light board 71 has multiple square plates 71, forming matrix lighting, resulting in good lighting effects. The entire LED light board 71 is fixed by multiple bolts, making it difficult to detach in the event of an explosion, thus maintaining its explosion-proof effect. Combined with the metal frame 5, it will not easily break in the event of an explosion, ensuring that the metal frame 5 will not be blown apart when the LED beads explode. The glass is explosion-proof glass. The overall explosion-proof performance is increased.
[0020] The front cover is fitted with a sealing ring at the location of the heat dissipation back panel 1. For outdoor installation, waterproof performance is required. Improved waterproofing is essential.
[0021] The inner sides of both ends of the U-shaped frame 2 are provided with anti-slip textures. After the U-shaped frame 2 forms different included angles with the two sides of the heat dissipation backplate 1, the U-shaped frame 2 is fixed to the heat dissipation backplate 1 with bolts. The angle can be adjusted as needed, and the irradiation direction can be set during installation.
[0022] A wiring bolt 41 is provided at the center of the cylinder cover 4. The control wire passes through the wiring bolt 41, and sealing the wiring bolt 41 can achieve waterproofing inside the circuit cylinder 3.
[0023] The metal frame 5 is provided with reinforcing ribs 51 to improve its strength and prevent it from easily exploding or cracking in the event of an explosion.
[0024] The number of mounting areas on the front sidewall of the heat dissipation backplate 1 is 1-4. The number of LED floodlights is set according to the width requirements of the installation location, i.e., the lighting effect is set for the same location.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
