Description

Technical Field

[0001] This utility model relates to the field of marine lighting technology, and in particular to a mother ship marker light. Background Technology

[0002] The purpose of the mothership's marker lights is to provide helicopter pilots with light information to identify the mothership at night or during low-visibility days. When requesting a helicopter to return to base, a return-to-base light signal can be issued.

[0003] Given the application environment of mothership indicator lights, high reliability and ease of maintenance are required. A dual-light source design is typically employed, allowing for immediate switching to a backup light source in case of main light source failure. Existing solutions usually employ a single-unit design, with two light sources housed within a single casing. However, if one light source fails, the entire light source module must be disassembled to separate the main light source module for replacement or repair, making maintenance inconvenient. Summary of the Invention

[0004] The purpose of this utility model is to provide a mothership marker light, which adopts an independent stacked arrangement of a main light source module and a backup light source module, thereby improving the convenience of maintenance of the main light source module and the overall reliability of the light fixture.

[0005] To solve the above-mentioned technical problems, the present invention provides a technical solution as follows: a mothership marker light, comprising: a base; a backup light source module disposed on the base; a main light source module independently mounted above the backup light source module via a detachable connection structure, forming a stacked structure with the backup light source module; and a control circuit for monitoring the working status of the main light source module, and controlling the mothership marker light to automatically switch to illumination powered by the backup light source module when the main light source module fails, and to automatically switch back to illumination powered by the main light source module after the main light source module recovers.

[0006] Furthermore, the detachable connection structure includes a connecting screw, which passes through the top cover and base of the main light source module in sequence and is threadedly connected to the top cover of the backup light source module, so that the main light source module can be separated from the backup light source module by simply removing the connecting screw.

[0007] Furthermore, it also includes a waterproof cover, which covers the top of the upper cover of the main light source module and is connected to the upper cover through a sealing structure to seal the head of the connecting screw within the sealed space formed by the waterproof cover and the upper cover.

[0008] Furthermore, both the main light source module and the backup light source module include a base, a top cover, a lampshade, a light source board, and a reflector. The lampshade is cylindrical and disposed between the base and the top cover. The light source board and the reflector are located within a sealed cavity formed by the base, the top cover, and the lampshade. The upper end of the lampshade is connected to the top cover, and the lower end of the lampshade is connected to the base, all through a labyrinth-type sealing structure. A sealing gasket is provided at the joint surface of the labyrinth-type sealing structure.

[0009] Furthermore, the base is provided with a boss extending toward the upper cover, and fasteners pass through the boss and connect to the upper cover to press and fix the upper cover, lampshade and base together; an elastic heat-conducting pad is provided between the mating surfaces of the boss and the upper cover.

[0010] Furthermore, the base is provided with a wire hole, and a wire sleeve is embedded in the wire hole. The wire sleeve and the cable passing through it are interference fit.

[0011] Furthermore, the base and the backup light source module, as well as the main light source module and the backup light source module, are sealed together by a labyrinthine waterproof structure and a sealing ring.

[0012] Furthermore, the base has a wiring cavity that opens toward the mounting base surface. The inner wall of the opening end of the wiring cavity is provided with an annular step. A base plate is fixed to the annular step by fasteners to close the wiring cavity. The base plate is offset from the mounting base surface, so that the base plate and the side wall of the base together form a concave waterproof groove.

[0013] Furthermore, at least one drainage groove extending to the outside is provided on the side wall of the waterproof groove.

[0014] Furthermore, a sealing ring is provided between the base plate and the mating surface of the annular step.

[0015] The mothership marker light provided by this utility model, compared with the prior art, features a detachable main light source module that is independently installed on the backup power supply. This facilitates disassembly and installation in case of a main light source module failure, making maintenance more convenient. The active switching between the main and backup light source modules via a control circuit increases the reliability of the mothership marker light. In particular, the waterproof cap sealing the screw heads, the labyrinth seal structure between the lamp cover and the top cover and base, the labyrinth seal structures between the light source modules and between the light source module and the base, and the waterproof groove and drainage channel on the base effectively enhance the overall sealing performance of the mothership marker light. Furthermore, the elastic heat-conducting pad between the top cover and the base boss forms a unified heat dissipation system, increasing the heat conduction efficiency between the top cover and the base and improving the heat dissipation performance of the light source module.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0020] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0021] like Figure 1-2As shown, one embodiment of this utility model relates to a mothership indicator light, including a base 30, and a main light source module 10 and a backup light source module 20 arranged sequentially from top to bottom on the base 30. The backup light source module 20 is arranged adjacent to the base 30 and is independently installed above the backup light source module 20 through a detachable connection structure, forming a stacked structure with the backup light source module 20. The mothership indicator light also includes a control circuit for switching between the main light source module 10 and the backup light source module 20, for monitoring the working status of the main light source module 10, and when the main light source module 10 located on the upper layer fails, the mothership indicator light automatically switches to the lower backup light source module 20 for illumination under the action of the control circuit; when the main light source module 10 is repaired, it automatically switches back to the main light source module 10 for illumination.

[0022] The main light source module 10 and the backup light source module 20 have the same or similar structure, both including a base 12, 22, a top cover 11, 21, a lampshade 13, 23, a light source plate 15, 25, and a reflector 16, 26. The top cover 11, 21, the base 12, 22, and the lampshade 13, 23 together form a sealed cavity to accommodate the light source plate 15, 25 and the reflector 16, 26. The lampshade 13, 23 is a hollow cylindrical shape and is set between the top cover 11, 21 and the base 12, 22. The side wall of the lampshade 13, 23 forms a light-transmitting area. The light emitted by the light source plate 15, 25 is emitted through the side wall of the cylindrical light-transmitting lampshade 13, 23 to illuminate the environment. The upper end of the lampshade 13,23 is connected to the upper cover 11,21 through a labyrinth-type sealing structure, and the lower end is connected to the base 12,22 through a labyrinth-type sealing structure. Preferably, a sealing gasket 14,24 is also provided at the connection between the end of the lampshade 13,23 and the upper cover 11,21 and the base 12,22 to increase the sealing performance of the light source module. In one example, the base 12,22 extends centrally toward the top cover 11,21 and has protrusions 17,27. Fasteners 50 pass through the protrusions 17,27 and connect with the top cover 11,21 to secure the top cover 11,21 and the base 12,22. At the same time, the gap between the top cover 11,21 and the base 12,22 can be adjusted by tightening or loosening the fasteners 50 to control the compression of the gaskets 14,24, forming a limiting sealing structure. This ensures that the gaskets 14,24 are in a suitable compression range, avoiding insufficient compression leading to a decrease in sealing performance or excessive compression leading to a reduction in the lifespan of the gaskets 14,24. Preferably, an elastic thermal pad 80 is provided between the bosses 17,27 and the upper cover 11,21. The upper cover 11,21 and the base 12,22 are connected by the thermal pad 80, so that the upper cover 11,21 and the base 12,22 form a heat dissipation unit, which increases the heat conduction efficiency between the upper cover 11,21 and the base 12,22 and is beneficial to increasing the heat dissipation performance of the light source module. The thermal pad 80 is made of an elastic thermally conductive material.

[0023] One embodiment relates to a mothership marker light, including a base 30, and a main light source module 10 and a backup light source module 20 arranged sequentially from top to bottom on the base 30. The base 30 and the backup light source module 20 are detachably fixedly connected by fasteners 50, and the backup light source module 20 and the main light source module 10 are detachably fixedly connected by connecting screws 60. During installation, the connecting screws 60 pass through the upper cover 11 and the base 12 of the main light source module 10 in sequence, and are then threaded to the upper cover 21 of the backup light source module 20. When the main light source module 10 needs maintenance, only the connecting screws 60 need to be loosened, which allows for convenient and quick disassembly of the upper-level main light source module 10. That is, only the connecting screws 60 need to be removed to separate the main light source module 10 from the backup light source module 20, without disassembling the entire light fixture. After the main light source module 10 is repaired, the light fixture will automatically switch back to the main light source module 10. Therefore, each maintenance only requires replacing the upper-level main light source module 10. Preferably, to prevent water leakage at the connecting screw 60 and improve the overall sealing performance of the mothership indicator light, a waterproof cover 90 is added to the top of the upper cover 11 of the main light source module 10. The waterproof cover 90 covers the top of the upper cover 11 of the main light source module 10 and is connected to the upper cover 11 through a sealing structure, so as to seal the head of the connecting screw 60 within the space enclosed by the waterproof cover 90 and the upper cover 11. In one example, the waterproof cover 90 is sealed to the upper cover 11 of the main light source module 10 through an O-ring 40 and a labyrinth sealing structure, covering the head of the connecting screw 60 exposed on the upper cover 11 of the main light source module 10 within the sealed space, preventing the connecting screw 60 from being directly corroded by the external environment, thereby effectively improving the overall sealing performance of the mothership indicator light.

[0024] In one embodiment, a mothership marker light is provided. The base 12 of the main light source module 10, the top cover 21 of the backup light source module 20, and the base 22 of the backup light source are also provided with cable passage holes. A cable passage sleeve is embedded in the cable passage hole. The cable of the light source module passes through the cable passage sleeve and is led out. The cable passage sleeve and the cable are interference fit to fix and seal the cable, so as to improve the sealing performance of the inner cavity where the light source boards 15 and 25 are located, and to help increase the stability of the cable, reduce the probability of cable displacement during use, and increase the service life of the light source module.

[0025] One embodiment relates to a mothership indicator light, including a base 30, and a main light source module 10 and a backup light source module 20 arranged sequentially from top to bottom on the base 30. To further improve the protective performance of the mothership indicator light and prevent moisture from entering its interior, the connection between the base 30 and the backup light source module 20 is sealed with a labyrinth-type waterproof structure and an O-ring 40, and the connection between the main light source module 10 and the backup light source module 20 is also sealed with a labyrinth-type waterproof structure and an O-ring 40.

[0026] One embodiment relates to a mothership marker light, including a base 30, and a main light source module 10 and a backup light source module 20 arranged sequentially from top to bottom on the base 30. The mothership marker light is connected to the mounting base via the base 30 to complete the overall installation and fixation of the light fixture. To increase the adaptability of the mothership marker light to the operating environment and to increase its protective performance and service life, the base 30 adopts a concave waterproof structure. Specifically, the base 30 has a hollow wiring cavity 301, and the wiring cavity 301 has a wiring terminal 35 inside for connecting the mothership marker light to an external power supply device. The opening end 31 of the wiring cavity 301 faces the mounting base surface 36 of the base 30. The inner wall of the wiring cavity 301 protrudes adjacent to the mounting base surface 36 and has an annular step 32. The base plate 33 of the base 30 is fixedly connected to the annular step 32 by fasteners 50, closing the wiring cavity 301. The base plate 33 is offset from the mounting base surface 36, and the base plate 33 serves as the bottom of the groove 37, forming a concave waterproof groove 37 with the side wall of the base 30. When the mothership's indicator lights are washed by rain, the base plate 33 will not be directly impacted, further reducing the risk of water entering the wiring cavity 301 and helping to further increase the sealing performance of the wiring cavity 301.

[0027] In one example, an O-ring 40 is also provided between the base plate 33 and the annular step 32 to seal the gap between the base plate 33 and the annular step 32, thereby increasing the sealing performance of the wiring cavity 301. Preferably, the side wall of the waterproof groove 37 is provided with at least one through-drainage groove 34, so that the inside of the groove 37 is connected to the outside of the base 30. When the mothership marker light is washed by rainwater, the water can be quickly discharged under the guiding effect of the through-drainage groove 34, avoiding the long-term erosion of the sealing structure of the wiring cavity 301 by rainwater. This helps to reduce the impact force of water flow on the sealing structure of the wiring cavity 301, further reducing the risk of water ingress into the wiring cavity 301 and improving the sealing performance of the wiring cavity 301.

[0028] The mothership marker light provided by this utility model features a detachable main light source module that can be independently installed on a backup power supply. This facilitates disassembly and installation in case of a main light source module failure, making maintenance more convenient. The active switching between the main and backup light source modules via a control circuit enhances the reliability of the mothership marker light. The overall sealing performance of the mothership marker light is effectively improved through the sealing of the screw heads with waterproof covers, the labyrinth seal structure between the lamp cover and the top cover and base, the labyrinth seal structures between the light source modules and between the light source module and the base, and the waterproof groove and drainage channel in the base. In particular, the elastic heat-conducting pad between the top cover and the base boss forms a unified heat dissipation system, increasing the heat conduction efficiency between the top cover and the base and improving the heat dissipation performance of the light source module.

[0029] 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.
