[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 , Figure 2 , Figure 3As shown, the utility model is an LED turtleback lamp with efficient heat dissipation, comprising a lamp holder 1 and a lamp body 2 mounted on the lamp holder 1, a turtleback shell 3 is mounted on the outside of the lamp holder 1 and the lamp body 2, the turtleback shell 3 is an aluminum shell, a threaded cylinder 4 is mounted on the turtleback shell 3, the threaded cylinder 4 is threadedly connected with a sleeve 5, a cavity 6 is formed between the sleeve 5 and the lamp holder 1, a graphene plate 7 is mounted at the center of the bottom of the cavity 6, the sleeve 5 is provided with a water outlet 8, and a heat dissipation fin 9 is mounted on the outside of the sleeve 5;

[0024] The tortoise shell 3 is provided with a light-through groove 10 , the output end of the lamp body 2 is placed in the light-through groove 10 , and the light-through groove 10 is provided with a water-through hole 11 communicating with the cavity 6 .

[0025] In this embodiment, when using an LED turtleback lamp with efficient heat dissipation, the lamp holder 1 and the lamp body 2 are installed in the turtleback shell 3, and then the turtleback shell 3 is installed on the sleeve shell 5 in the manner of screwing the threaded tube 4 into the sleeve shell 5 to complete the installation. According to the local rainwater conditions, it is selected whether to block the water outlet 8. If there is a lot of rain, it is not blocked, and if there is little rain, it is blocked. Then the sleeve shell 5 is installed in the use position to complete the installation;

[0026] During use, the light of the lamp body 2 is irradiated from the light-through groove 10 to achieve the lighting effect. The graphene plate 7 at the bottom dissipates the heat generated by the lamp holder 1 by heat exchange. The water falling on rainy days or the water poured by relevant environmental protection personnel enters the cavity 6 from the water hole 11 and accumulates in the cavity 6 to achieve the purpose of liquid cooling. Because the water outlet 8 is located at the bottom and the bottom is in contact with the ground, the water in the cavity 6 is lost slowly, which can achieve the purpose of long-term heat dissipation. Of course, controlling the aperture of the water outlet 8 can also achieve the purpose of controlling the loss rate. The heat dissipation fins 9 on the outside of the cavity 6 can ensure the temperature of the water in the cavity 6 and ensure the heat dissipation effect.

[0027] Preferably, a mounting groove 12 is opened at the bottom of the cavity 6, and the graphene plate 7 is placed in the mounting groove 12. A sealing ring 13 is installed at the opening of the mounting groove 12. Such a design fixes the position of the graphene plate 7 to ensure that it is directly below the lamp holder 1, maximizes the contact area with the turtle shell 3, and ensures the heat transfer effect. The installation of the sealing ring 13 prevents liquid from entering the mounting groove 12. In fact, the installation measures of the graphene plate 7 can also be considered according to specific circumstances.

[0028] The water outlet 8 is preferably matched with a rubber plug. With this design, the water outlet 8 can be blocked in areas with less rain, so that water can be stored in the cavity 6 to maintain a long-term cooling effect of rainwater. In fact, blocking measures for the water outlet 8 can also be considered according to specific circumstances.

[0029] Preferably, the casing 5 is provided with fixing holes 15, and there are at least three fixing holes 15. Such a design ensures the fixing effect of the casing 5. In fact, the number of fixing holes 15 or the fixing measures for the casing 5 can also be considered according to specific circumstances.

[0030] Preferably, four light-through grooves 10 are provided, evenly arranged on the circumference of the turtle shell 3. With this design, four groups of lights can be provided to ensure the lighting effect and lighting range. In fact, the number of light-through grooves 10 can also be considered according to specific circumstances.

[0031] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
