The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a low-temperature LED three-proof lamp of the utility model comprises a lamp housing 1 and a lamp shade 2, first arc plates 5 are installed on both sides of the opening of the lamp housing 1, both sides of the opening end surface of the lamp shade 2 are protruded to form a sealing portion 13, and second arc plates 6 are installed on the bottom surface of the sealing portion 13, the sealing portion 13 and the second arc plate 6 are inserted into the interior of the lamp housing 1, the second arc plate 6 and the first arc plate 5 are arranged opposite to each other, and the middle of the first arc plate 5 and the second arc plate 6 are combined to form a cylindrical cavity, and a fixing column 7 for sealing and fixing the lamp housing 1 and the lamp shade 2 is inserted into the cylindrical cavity.

[0023] In this embodiment, the bottom surfaces of the first arc-shaped plates 5 all form parallel sealing surfaces, and the top surfaces of the sealing portions 13 all abut against the sealing surfaces.

[0024] In this embodiment, a connection groove 11 of a frame structure is provided on the open end surface of the lamp housing 1, and the open end surface of the lampshade 2 protrudes opposite to the connection groove 11 to form a connection frame 8. The connection frame 8 is inserted into the connection groove 11 and is set in contact with the inner wall surface of the connection groove 11.

[0025] In this embodiment, a screw hole 12 is provided on one end face of the lamp housing 1 opposite to the cylindrical cavity, one end of the fixing column 7 extends through the screw hole 12 to the outside, and a handwheel 4 is installed, and a screw thread is provided on one end of the fixing column 7 close to the handwheel 4, and the fixing column 7 is engaged with the screw hole 12 through the screw thread.

[0026] In this embodiment, the diameter of the fixing column 7 matches the inner diameter of the cylindrical cavity, which increases the tightness between the fixing column and the cylindrical cavity, thereby sealing the gap between the first arc plate and the second arc plate.

[0027] In this embodiment, a wiring tube 14 communicating with the interior of the lamp housing 1 is installed on the other end of the lamp housing 1, and the wires on the lamp board can be connected to external equipment along the wiring tube.

[0029] After the lamp board is installed inside the lamp housing, the top surface of the lamp board can directly contact the heat dissipating fins. However, in order to avoid direct contact between the conductive areas on the lamp board (such as pins, pads, etc.) and the heat dissipating fins, avoidance grooves are provided on the heat dissipating fins. Thus, when the heat dissipating fins contact the lamp board, conduction is avoided. Through direct contact with the heat dissipating fins, the heat on the lamp board can be directly discharged along the heat dissipating fins, thereby increasing the heat dissipation effect.

[0030] During assembly, the second curved plate on the lampshade can be inserted into the interior of the lamp housing until the second curved plate is arranged opposite to the first curved plate, the two can be combined to form a cylindrical cavity, and the sealing part can be against the sealing surface;

The second arc plate can be positioned on the first arc plate through the fixing column, and the installation of the lampshade is completed. After the lampshade is fixed, the connecting frame can be inserted into the connecting groove. The sealing between the lamp housing and the lampshade can be ensured by the cooperation between the first arc plate, the second arc plate, the fixing column, the sealing part and the connecting frame.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
