[0027] like Figure 1-2As shown, one embodiment of this utility model relates to a navigation signal light, including a detachably fixed base 20 and a lamp head assembly 10. The base 20 has a cavity 21, and a light source control device 30 is provided inside the cavity 21. The lamp head assembly 10 includes a cylindrical lampshade 12 with an open port. The inner cavity of the lampshade 12 is provided with a heat sink 16 and a light source plate 17 fixed to the heat sink 16. The lower end opening of the lampshade 12 is provided with a base plate 13. The base plate 13 is fixedly connected to one end of the heat sink 16 axially by screws 15. The upper end opening of the lampshade 12 is covered by a top cover 11. The top cover 11 is recessed with a connecting groove 111 facing the heat sink 16. The bottom wall 112 of the connecting groove 111 is fixedly connected to the other end of the heat sink 16 axially by screws 15. The opening end of the connecting groove 111 is sealed with a plug 14. The edge portion 1411 of the plug 14 extends beyond the opening end face of the connecting groove 111 and abuts against the surface of the top cover 11. Preferably, the upper cover 11 is made of forged aluminum with a hard anodized black surface, which is UV resistant and prevents fading. The upper cover 11 has a labyrinth-type sealing structure at its upper port facing the lampshade 12, forming a labyrinth-type sealed connection with the upper port of the lampshade 12; the bottom plate 13 has a labyrinth-type sealing structure at its lower port facing the lampshade 12, forming a labyrinth-type sealed connection with the lower port of the lampshade 12. In one example, a sealing gasket 18 is provided between the upper cover 11 and the upper port of the lampshade 12, and between the bottom plate 13 and the lower port of the lampshade 12. The upper cover 11 and the bottom plate 13 are pressed against the port of the lampshade 12 by the tightening of screws 15, forming a press-fit seal. The labyrinth-type sealing structure between the port of the lampshade 12 and the upper cover 11 and the bottom plate 13 is formed by the sealing gasket. The press-fit seal between the upper cover 11 and the bottom plate 13 and the port of the lampshade 12 by the tightening of screws 15 further enhances the sealing performance of the navigation signal light. In one example, an arc-shaped light shield 19 is provided between the upper cover 11 and the bottom plate 13. The light shield 19 is cut by laser cutting and rolled into a circle. The light shield 19 is located outside the lampshade 12 and is used to adjust the illumination direction and range of the light source.

[0028] like Figure 2As shown, in one embodiment, a navigation signal light is involved. A plug 14 is threadedly sealed to a connecting groove 111. The plug 14 includes a sealing plate 141 and a connecting arm 142 extending perpendicularly to the end face of the sealing plate 141. The connecting arm 142 has an external thread on its outer periphery, and the side wall 113 of the connecting groove 111 has an internal thread that matches the external thread. After the screw 15 passes through the bottom wall 112 to fasten the upper cover 11 to the radiator 16, the plug 14 is screwed to the connecting groove 111 through the connecting arm 142 to seal the port of the connecting groove 111. The edge 1411 of the plug abuts against the upper surface of the upper cover 11 to prevent water, dust, etc. in the external environment from directly corroding the connection of the screw 15. Preferably, a second sealing ring 151 is provided between the screw 15 and the bottom wall 112 to seal the gap between the screw 15 and the bottom wall 112, and a first sealing ring 1412 is provided between the sealing plate 141 and the top cover 11 to seal the gap between the sealing plate 141 and the top cover 11, forming a multi-protection sealing structure, further enhancing the sealing effect of the navigation signal light, enhancing its protective performance, and increasing the environmental adaptability of the navigation signal light.

[0029] like Figure 3-4 As shown, in one embodiment, a navigation signal light is involved, in which a plug 14 is snapped and sealed to a connecting groove 111. The plug 14 includes a sealing plate 141 and an elastic snap-fit ​​arm 143 extending perpendicularly to the end face of the sealing plate 141. The plug 14 is snapped and fixed to the connecting groove 111 by the snap-fit ​​arm 143. Specifically, the end of the snap-fit ​​arm 143 is provided with a barb 1431, and the side wall 113 of the connecting groove 111 is provided with a groove 1131 that mates with the barb 1431. After the screw 15 passes through the bottom wall 112 to fasten the top cover 11 to the radiator 16, the snap-fit ​​arm 143... 3. Insert the screw into the connecting groove 111. The side wall 113 presses the barb 1431, causing the snap-fit ​​arm 143 to elastically deform and enter the connecting groove 111. When the barb 1431 descends to the corresponding position of the snap-fit ​​groove 1131, under the rebound force of the snap-fit ​​arm 143, the barb 1431 snaps into the snap-fit ​​groove 1131, blocking each other and preventing the plug 14 from falling off the top cover 11. This makes the plug 14 snapped and fixed in the connecting groove 111. The edge of the plug 1411 abuts against the upper surface of the top cover 11, avoiding direct corrosion of the screw 15 connection by water, dust and other external factors. Preferably, a second sealing ring 151 is provided between the screw 15 and the bottom wall 112 to seal the gap between the screw 15 and the bottom wall 112, and a first sealing ring 1412 is provided between the sealing plate 141 and the top cover 11 to seal the gap between the sealing plate 141 and the top cover 11, forming a multi-protection sealing structure, further enhancing the sealing effect of the navigation signal light, enhancing its protective performance, and increasing the environmental adaptability of the navigation signal light.

[0030] like Figure 5-7As shown, in one embodiment, a navigation signal light is provided, including a base 20 and a lamp head assembly 10 fixed above the base 20. The base 20 has a cavity 21, and a light source control device 30 is provided inside the cavity 21. The open end of the cavity 21 faces the lamp head assembly 10. The lamp head assembly 10 has a base plate 13 facing the open end of the cavity 21. The base plate 13 is detachably fixed to the open end of the cavity 21. A fault detection plate 50 is fixed on the side of the base plate 13 facing the cavity 21, which is connected to the light source plate 17 and the light source control device 30, and can perform self-testing on the entire light. A wiring terminal 31 is fixed on the side of the base 20. A plug-in wire harness 32 is provided between the lamp head assembly 10 and the base 20. One end of the plug-in wire harness 32 is fixed to the wiring terminal 31, and the other end passes through the base plate 13 and connects to the lamp head assembly 10. The buffer section of the wire harness 32 is housed in the cavity 21. A breather valve 22 is installed at the bottom of the base 20. By drawing in or expelling gas through the breather valve 22, the internal pressure of the lamp body is adjusted to balance the external pressure of the lamp body, preventing the lamp from deforming or failing to seal due to excessively high or low air pressure, thereby protecting the sealing performance of the lamp.

[0031] In one example, the base plate 13 and the base 20 are detachably fixedly connected by anti-detachment screws 131. Preferably, a sealing element 23 is provided between the base plate 13 and the base 20 to seal the gap between them. When the lamp head assembly 10 is disassembled from the base 20, the anti-detachment screws 131 are connected to the base plate 13 and can be moved along with the lamp head assembly 10. Preferably, an anti-detachment rope 40 is provided between the base plate 13 and the base 20. One end of the anti-detachment rope 40 is fixed inside the cavity 21, and the other end is fixed to the side of the base plate 13 facing the cavity 21. When the lamp head assembly 10 is separated from the base 20, the anti-detachment rope 40 can effectively restrain the distance between the lamp head assembly 10 and the base 20, preventing the distance from exceeding the extension limit of the wiring harness 32, which could cause the wiring harness 32 to be damaged or fall off, resulting in maintenance problems. When replacing the light source control device 30 or detecting the fault detection board 50, simply loosen the four anti-detachment screws 131 to open the lamp head assembly 10 and the base 20 in a flip-top manner. The two are connected by an anti-detachment rope 40, preventing the lamp head assembly 10 from completely detaching and being lost. Simultaneously, it protects the wiring harness 32 from excessive pulling due to the separation of the lamp head assembly 10 and the base 20, thus ensuring the stability of the wiring harness 32 connection. The anti-detachment rope 40 and anti-detachment screws 131 effectively prevent detachable materials such as the anti-detachment screws 131 and the lamp head assembly 10 from falling off and being lost during the disassembly and maintenance of the lamp head assembly 10 and the base 20, improving maintenance efficiency. Preferably, the anti-detachment screws 131 are steel wire ropes.

[0032] The navigation signal light provided by this utility model achieves a secure connection between the upper cover and the radiator through the design of the upper cover connecting groove. The sealing of the connecting groove port with a plug, and the extension of the plug's edge abutting against the upper cover surface, improves the overall integrity and sealing effect of the upper cover, thus enhancing the safety and protective performance of the navigation signal light. The arrangement of the base plate and upper cover being fixed to both ends of the radiator with screws simplifies the structure of the lamp head assembly. Simultaneously, the base plate and upper cover, under the tightening action of the screws, can achieve a press-fit seal at the lamp cover port, further improving the sealing performance of the lamp head assembly. The inclusion of anti-detachment screws and anti-detachment ropes protects the wiring harness from excessive pulling during navigation signal light maintenance, preventing the loss of removable materials and improving maintenance efficiency.

[0033] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
