DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0028] Referring to Figures 1-4 A kind of LED light emitting device of high water pressure resistance, including the pressure-resistant shell 1 of rectangular arrangement, pressure-resistant shell 1 top and bottom end are equipped with cover plate 4, the inside of pressure-resistant shell 1 is provided with lighting assembly 2;

[0029] Lighting assembly 2 includes the installation slot of being opened in the four vertical faces of pressure-resistant shell 1, LED lamp plate 26 is all arranged in the inside of installation slot, high-pressure light-transmitting glass 21 for sealing installation slot is all installed on the four vertical faces of pressure-resistant shell 1, heat-conducting groove is opened in the inside of pressure-resistant shell 1, heat-conducting plate 27 is arranged in the inside of heat-conducting groove, and the side of LED lamp plate 26 is pasted tightly with the bottom end of heat-conducting plate 27, the top end of heat-conducting plate 27 is fixedly connected with heat-conducting sheet 28, and the side, fixedly connected with a plurality of groups of heat dissipation fins 22, of cover plate 4 is away from pressure-resistant shell 1.

[0030] Preferably, high-pressure light-transmitting glass 21 is filled with a certain amount of dry gas (nitrogen or air),

[0031] When the LED light emitting device is used underwater, the high-pressure light-transmitting glass 21 will withstand external pressure due to the increase of external water pressure. By filling the high-pressure light-transmitting glass 21 with an appropriate amount of dry gas, when the temperature decreases (the temperature usually decreases when the water depth increases), the volume of the gas in the high-pressure light-transmitting glass 21 will shrink. The negative pressure generated when the gas shrinks will reduce the pressure difference of the high-pressure light-transmitting glass 21, thereby reducing the risk of the high-pressure light-transmitting glass 21 breaking. On the other hand, when the water temperature rises or the use of the LED light emitting device causes the internal temperature to rise, the gas in the high-pressure light-transmitting glass 21 will expand, thereby maintaining the balance of the gas pressure in the high-pressure light-transmitting glass 21 and the external pressure, avoiding the high-pressure light-transmitting glass 21 from breaking.

[0032] The high water pressure resistant LED light emitting device, when in use, attracts fish through the light emitting of the LED lamp plate 26. When the LED lamp plate 26 works for a long time, heat will be generated. The heat will be conducted to the heat dissipation fins 22 through the heat conducting plate 27 and the heat conducting sheet 28, and then conducted out of the device through the heat dissipation fins 22. The heat is taken away by the flow of seawater, so as to realize the cooling of the LED lamp plate 26 inside the pressure resistant shell 1, ensure the normal work of the internal elements of the pressure resistant shell 1, improve the service life of the device, and fill the heat conducting silicone grease between the heat conducting sheet 28 and the heat dissipation fins 22 when the cover plate 4 is installed, so as to ensure good heat conduction.

[0033] The pressure resistant shell 1 adopts a multi-layer composite structure, and from inside to outside, it is sequentially provided with a supporting layer, a buffer layer and a protective layer. The protective layer is made of high-strength wear-resistant plastic, which can prevent the shell from being scratched and worn.

[0034] The bottom end of the heat dissipation fins 22 penetrates through the surface of the cover plate 4 and extends to the bottom surface of the cover plate 4, and is tightly attached to the heat conducting sheet 28. A sealing element is arranged between the heat dissipation fins 22 and the cover plate 4. The outer surface of the high-pressure transparent glass 21 is in an arc structure.

The pressure resistant shell 1 is fixedly connected with a sealing ring pad 29 at the side close to the edge of the LED lamp plate 26.

[0035] The sealing ring pad 29 can ensure the sealing effect between the high-pressure transparent glass 21 and the pressure resistant shell 1. The installation groove at the side close to the high-pressure transparent glass 21 of the pressure resistant shell 1 is in a trapezoidal structure. When the high-pressure transparent glass 21 is subjected to water pressure, the inclined surface of the high-pressure transparent glass 21 will be tightly attached to the inner side of the installation groove, so as to ensure the sealing and waterproof effect of the pressure resistant shell 1.

[0036] The two groups of cover plates 4 are connected with the pressure resistant shell 1 through screws. The cover plate 4 is screw-connected with a protective rod 24 at four corners of the surface. The two groups of cover plates 4 are connected through the protective rods 24. The cover plate 4 is fixedly connected with a lifting hook 23 at four corners of the upper surface.

[0037] Preferably, the two groups of cover plates are connected with the pressure resistant shell 1 through flanges supplemented by bolts. The flanges are connected through a special-shaped groove design, and are placed with silica gel pads and sheaths, and are supplemented by high-viscosity high-temperature-resistant and high-pressure-resistant adhesive to form a high-pressure-resistant protective layer.

[0038] The two groups of cover plates 4 are tightly attached to the pressure resistant shell 1 through the four protective rods 24, so as to improve the stability of the device installation. At the same time, the protective rods 24 can protect the high-pressure transparent glass 21 to some extent, so as to improve the anti-collision effect of the high-pressure transparent glass 21 and the pressure resistant shell 1. The lifting hook 23 is convenient for connecting the device with an external rope.

[0039] The installation cylinder 25 is fixedly connected to the side close to the heat dissipation fins 22 of the cover plate 4. The pressure sensor 210 is installed in the installation cylinder 25.

[0040] The inside of the pressure-resistant shell 1 is provided with a remote information transmission module and is electrically connected with the pressure sensor 210 and the LED lamp panel 26, which can control the light change of the LED lamp panel 26, emit specific light spectrum to attract fish according to the fishing demand, and improve the flexibility of the device. The pressure sensor 210 can detect the water pressure data of the device located underwater in real time, and transmit the data to the controller through the remote information transmission module, so that the operator can adjust the water depth of the device according to the pressure data, avoid excessive water pressure, and damage the device. The pressure sensor 210 is located inside the mounting cylinder 25, so that the pressure sensor 210 is not easily affected by the flow interference, and the accuracy of the measurement data of the pressure sensor 210 is ensured. The lithium battery module is installed in the inside of the pressure-resistant shell 1, which can continuously supply power for the remote information transmission module, the pressure sensor 210 and the LED lamp panel 26.

[0042] When the device is impacted, the anti-collision fins 31 will push the movable plates 32 to move and squeeze the buffer springs 33 to contract, so as to absorb the impact force generated by the impact through the buffer springs 33, so that the device can withstand a certain degree of collision impact underwater, ensure the normal work of the device, and improve the reliability and service life of the device in actual application.
