[0025] The electrical connection mechanism includes a first connecting seat 6, a second connecting seat 7 and a fastener 10. The second connecting seat 7 is provided with a connector 71. The fastener 10 is provided in the lamp body 1. The connector 71 is passed through the lamp body 1 and is connected to the fastener 10, so that the second connecting seat 7 is fixed on the lamp body 1; the first connecting seat 6 is provided with a first electrical connector 8, and the second connecting seat 7 is provided with a second electrical connector 9 and a sealing assembly provided on the second electrical connector 9; the second electrical connector 9 is inserted into the first connecting seat 6, and the second electrical connector 9 is sealed with the first connecting seat 6 through the sealing assembly, so that the first electrical connector 6 and the second electrical connector 7 are electrically connected.

[0026] The utility model is provided with an electrical connection mechanism for realizing power on and off of the lamp in water. Specifically, the mechanism is connected by plugging and utilizing the sealing component on the second electrical connector. When the second electrical connector is inserted into the first connector, the water in the first connector is discharged and the sealing component acts as a seal, so that the first electrical connector and the second electrical connector can be electrically connected. When the lamp is pulled out, the sealing component also acts as a seal, preventing water or foreign matter from being present between the first electrical connector and the second electrical connector, thereby ensuring the reliability of the electrical connection and realizing power on and off of the lamp in water. In addition, the lamp body is made of corrosion-resistant material, which ensures the corrosion resistance of the lamp, allowing the lamp to be used underwater for a long time without being damaged, thereby extending the service life of the lamp and reducing the cost of use.

[0027] Preferably, if Figure 2 、 4As shown, the lamp body 1 is provided with a through hole 131, and the connector 71 is provided through the through hole 131 and is threadedly connected to the fastener 10. The connector 71 has an external thread, and the fastener 10 has an internal thread. The fastener 10 is sleeved outside the connector 71 and is threadedly connected to the connector 71. The fastener 10 is preferably a nut.

[0028] More preferably, the second connection base 7 and the connector 71 are integrally formed. The first connection base 6 and the second connection base 7 are both made of rubber or silicone. The through hole and the connector 71 have an interference fit. Therefore, a seal is achieved between the connector and the lamp body, eliminating the need for a separate sealing ring.

[0029] More preferably, a gasket is provided between the fastener 10 and the lamp body 1. The provision of the gasket can make the connection between the fastener and the joint more secure and also play a certain sealing role.

[0030] More preferably, a sealing ring is provided between the lamp body 1 and the second connecting base 7 to further play a role in sealing water.

[0031] Preferably, the corrosion-resistant material is 316 stainless steel. 316 stainless steel not only has good corrosion resistance, but also good pressure resistance, so that the lamp can withstand greater water pressure underwater and extend its service life.

[0032] Specifically, such as Figure 1 、 3 As shown, the first connection base 6 is provided with a connecting insertion hole 61 and a drain hole 62. The first electrical connector 8 includes a first electrical connection portion 81, which is located on the inner wall of the insertion hole 61. The second electrical connector 9 includes a second electrical connection portion 91, which is inserted into the insertion hole 61 so that the sealing assembly drains water from the insertion hole 61 through the drain hole 62, and the first electrical connection portion 81 and the second electrical connection portion 91 abut against each other. The first electrical connector 8 is located within the first connection base 6, while the second electrical connector 9 is located outside the second connection base 7. That is, the first electrical connection portion 81 is located within the first connection base 6, and the second electrical connection portion 91 is located outside the second connection base 7. The second electrical connector is inserted into the insertion hole, so that the first and second electrical connection portions abut against each other, thereby achieving electrical connection. At the same time, the sealing assembly on the second electrical connector is sealed with the first connection base, draining water from the insertion hole through the drain hole, thereby preventing the first and second electrical connections from causing water to conduct electricity.

[0033] Preferably, the second electrical connector 9 and the plug hole 61 are interference-fitted to ensure a sealing effect between the sealing assembly and the first connecting seat.

[0034] Preferably, if Figure 3As shown, the sealing assembly includes a first sealing member 100 and a second sealing member 101, respectively, disposed at both ends of the second electrical connector 91. The second sealing member 101, the second electrical connector 91, the first sealing member 100, and the drain hole 62 are arranged in this order. Specifically, the first sealing member 100 wraps around one end of the second electrical connector 9, and the second sealing member 101 wraps around the other end of the second electrical connector 9. Therefore, the middle portion of the second electrical connector forms the second electrical connector. The arrangement of the first and second sealing members prevents water from flowing in from both ends of the second electrical connector, effectively providing a seal.

[0035] It should be noted that the first and second connection sockets 6 and 7 are each provided with a conductive wire, which is connected to the first and second electrical connectors 8 and 9, respectively. One end of the conductive wire from the second connection socket is connected to the second electrical connector, while the other end extends into the lamp body through a connector and is electrically connected to the power supply. The electrical connection mechanism can employ existing technical structures and will not be described in detail. A Marshall underwater plug-in connector can be used for this purpose.

[0036] In order to further improve the heat dissipation effect of the lamp, preferably, Figure 2 As shown, the present invention also includes a heat sink 5. The light source board 3, heat sink 5, and lamp body 1 are sequentially bonded and connected. The heat sink 5 is made of aluminum. The provision of the heat sink further accelerates heat transfer from the light source board to the lamp body, achieving the purpose of accelerated heat dissipation. The bonded light source board, heat sink, and lamp body increase the heat transfer area, thereby increasing the speed of heat transfer.

[0037] Among them, such as Figure 2 As shown, the lamp body 1 is provided with a light source slot 12, the bottom surface of which serves as a heat dissipation surface 121. The heat sink 5 is placed within the light source slot 12 and is in close contact with the heat dissipation surface 121. The light source board 3 is placed on the upper surface of the heat sink 5. The provision of the heat dissipation surface increases the contact area between the lamp body and the heat sink, thereby improving the speed of heat transfer.

[0038] like Figure 2 、 4 As shown, a light-transmitting groove 11 is provided above the light source groove 12, and the light-transmitting member 2 is placed in the light-transmitting groove 11; a power supply groove 13 is provided below the light source groove 12, and the power supply 4 is placed in the power supply groove 13, and the connector 71 is provided on the bottom wall of the power supply groove 13; the light-transmitting groove 11, the light source groove 12 and the power supply groove 13 are connected in sequence, and the areas of the light-transmitting groove 11, the light source groove 12 and the power supply groove 13 are reduced in sequence. The provision of the light-transmitting groove, the light source groove and the power supply groove is not only conducive to electrical connection, but also conducive to increasing the range of light irradiation, and also makes the structure of the lamp more compact and has better heat dissipation effect.

[0039] In summary, the utility model provides an underwater lighting fixture that can realize power on and off in water and is corrosion-resistant.

[0040] The above is a preferred embodiment of the present invention.
