[0025] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 to Figure 3 As shown, the utility model provides an embodiment of a deep-sea lamp pressure-resistant structure, including a lamp body 1, a light source 2 and a driving plate 3, the lamp body 1 including a lamp head 11, a barrel 12 and a light-transmitting cover 13, one end of the lamp head 11 is connected to the light-transmitting cover 13 to form an optical cavity A, and the other end of the lamp head 11 is connected to the barrel 12 to form a power cavity B; the light source 2 is arranged in the optical cavity A, and the driving plate 3 is arranged in the power cavity B, for supplying power to the light source 2; wherein the light-transmitting cover 13 is provided with a first light-transmitting surface 131 and a second light-transmitting surface 132, and the light emitted by the light source 2 passes through the first light-transmitting surface 131 and the second light-transmitting surface 132 in sequence, and the first light-transmitting surface 131 and the second light-transmitting surface 132 are both spherical arc surfaces convex to the outside of the optical cavity A.

[0027] In the present embodiment, the lamp holder 11 and the barrel 12 of the lamp body 1 form a power cavity B, and the driving board 3 for supplying power to the light source 2 is arranged in the power cavity B; the lamp holder 11 of the lamp body 1 is connected with the light-transmitting cover 13 to form an optical cavity A, and the light source 2 is arranged in the optical cavity A. The light-transmitting cover 13 is designed as a double-spherical arc surface design protruding out of the optical cavity A, which can withstand a larger load, help reduce the stress concentration of the structure, reduce the deformation of the light-transmitting cover 13, thereby improving the pressure resistance of the weak part of the light-transmitting cover 13. The light-transmitting cover 13 is not easy to break and fail under high-pressure environment, ensuring the normal operation of the light source 2 in the optical cavity A and the driving board 3 in the power cavity B, increasing the reliability and stability of the overall structure of the lamp, and being suitable for deep-sea lighting.

[0028] Preferably, in this embodiment, the closer the first light-transmitting surface 131 is to the central axis of the lamp body 1, the greater the distance from the second light-transmitting surface 132. That is, the thickness of the light-transmitting cover 13 is the largest at the central axis, and the farther from the central axis, the smaller the thickness of the light-transmitting cover 13, which helps to further improve the pressure resistance of the weak part of the light-transmitting cover 13.

[0029] The lamp holder 11 of this embodiment is provided with a first connector 111 and a second connector 112. In order to achieve good sealing performance and pressure resistance, the first connector 111 of the lamp holder 11 is provided with a first external thread on the outer wall, and the outer wall of the second connector 112 is provided with a second external thread, and at least one of the barrel body 12 and the light-transmitting cover 13 is provided with a first sealing groove 121 on the opposite end surface, and a first sealing ring 4 is provided in the first sealing groove 121, the barrel body 12 is connected to the first external thread, and the light-transmitting cover 13 is connected to the second external thread, and the barrel body 12 and the light-transmitting cover 13 press the first sealing ring 4, so that the optical cavity A and the power cavity B form waterproof cavities respectively.

[0030] The lamp holder 11 of this embodiment is cylindrical, and the barrel 12 is cylindrical, and the lamp holder 11 can provide good support for the side walls of the barrel 12 and the light-transmitting cover 13. In addition, the opposite end faces of the barrel 12 and the light-transmitting cover 13 overlap, and the shape of the lamp body 1 forms a capsule-like structure. The circumferential force uniformity of the lamp body 1 is good, and the pressure from the seawater on the second light-transmitting surface 132 on the light-transmitting cover 13 will be better transferred to the barrel 12 and the light-transmitting cover 13, thereby improving the pressure-bearing capacity of the light-transmitting cover 13. At the same time, the opposite end faces of the barrel 12 and the light-transmitting cover 13 overlap, which can help to quickly transfer the heat generated by the light source 2 from the lamp holder 11 and the barrel 12 to the seawater in sequence.

[0031] Preferably, the light-transmitting cover 13 is made of composite material, and the lamp head 11, the barrel 12 and the front cover 132 are all made of special alloy metal materials through a surface anti-corrosion process, which can withstand deep sea water pressure and resist corrosion.

[0032] The deep-sea pressure-resistant lamp of this embodiment also includes a watertight joint 5 connected to the driving plate 3. A second sealing groove 121 is provided at the end of the barrel 12 away from the lamp head 11. The watertight joint 5 is inserted into the second sealing groove 121 and closes the power cavity B.

[0033] The light source 2 can be a customized COB light source or a SMD lamp bead light source with a substrate. The light source 2 is attached to the lamp holder 11 through thermally conductive silicone, so that the light source 2 disperses heat to the barrel 12 through the lamp holder 11, and the barrel 12 quickly transfers the heat to the seawater.

[0034] In addition, the lamp holder 11 is provided with a through hole 113 connecting the optical cavity A and the power cavity B, and the driving board 3 is electrically connected to the light source 2 via a power line passing through the through hole 113 .

[0035] The light-transmitting cover 13 of the deep-sea lamp of this embodiment adopts an arc-shaped component to bear a larger load, reduce the stress concentration of the structure, and greatly reduce the deformation of the light-transmitting cover 13, thereby improving the pressure resistance of the weak part of the light-transmitting cover 13 and increasing the reliability and stability of the overall structure of the lamp. The deep-sea lamp has the advantages of good pressure resistance, a small number of parts, and simple assembly. In addition, the lamp is small in size and light in weight, which can effectively reduce the load of underwater operations and reduce energy consumption.

[0036] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
