Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, and in particular to a marine lighting fixture. Background Technology

[0002] Current ship lighting fixtures typically only have a single lighting function. In the damp and dark environment inside a ship, this can exacerbate feelings of oppression. Furthermore, when a ship is in motion, the hull vibrates significantly, and this vibration is directly transmitted to the lighting fixtures, causing the internal structure of the fixtures to become loose and affecting normal light output. Therefore, there is an urgent need for a lighting fixture that is better suited for use on ships. Utility Model Content

[0028] Reference Figures 1 to 4 A marine lighting fixture includes a main frame 100, a main light-emitting component, and a side light-emitting component. A top plate 110 is provided on the top side of the main frame 100. The main light-emitting component is located in the middle of the main frame 100 and below the top plate 110. A buffer layer 120 is provided between the main light-emitting component and the top plate 110. In practical applications, the buffer layer 120 can be made of materials such as foam or rubber. The main light-emitting component emits light downwards. The side light-emitting component is arranged around the main light-emitting component on the main frame 100 and emits light downwards.

[0029] As described above, a top plate 110 is provided on the top side of the main frame 100, which encloses the middle part of the main frame 100. The main light-emitting component is located in the middle of the main frame 100, while the side light-emitting components are arranged around the main light-emitting component. During operation, either the main light-emitting component or the side light-emitting component can be selected to emit light downwards, or both the main light-emitting component and the side light-emitting component can be selected to emit light downwards simultaneously, thus enriching the lighting functions. Furthermore, since a buffer layer 120 is provided between the main light-emitting component and the top plate 110, when the ship's vibration is transmitted to the main frame 100, the buffer layer 120 can effectively reduce the vibration transmitted to the main light-emitting component, thereby reducing the impact on the main light-emitting component. This can improve the diversity and flexibility of light output, better meet different usage scenarios, and reduce structural fatigue and damage caused by ship vibration, thereby improving the stability of use.

[0030] The interior of a ship is humid, with a large amount of water vapor in the air. To prevent water vapor from entering the interior of the main frame 100, in this embodiment, a first sealing groove is provided on the top side of the main frame 100. The first sealing groove extends around the main light-emitting assembly, and a first sealing ring 130 is provided inside the first sealing groove. When the top plate 110 is connected to the main frame 100, the first sealing ring 130 abuts against the bottom side of the top plate 110, which can better fill the gap between the top plate 110 and the main frame 100, and help prevent water vapor from entering from the assembly gap between the top plate 110 and the main frame 100.

[0031] There are several ways to connect the top plate 110 to the main frame 100. For example, the top plate 110 can be fixed to the top side of the main frame 100 by a snap-fit ​​connection. In this embodiment, the top side of the main frame 100 is provided with a first connecting groove. The first connecting groove is located on the side of the first sealing groove away from the main light-emitting component. Multiple first connectors are threaded through the top plate 110 and threaded into the first connecting groove. The multiple first connectors press the top plate 110 tightly onto the main frame 100. In this way, the top plate 110 is fixed to the main frame 100 by the threaded connection between the multiple first connectors and the main frame 100, which greatly improves the stability of the top plate 110 on the main frame 100. Furthermore, since the first connectors are connected to the first sealing ring 130 at a position away from the main light-emitting component, the influence of the connection structure between the top plate 110 and the main frame 100 on the sealing performance of both is effectively avoided.

[0032] Furthermore, in order to improve the ease of connection between the top plate 110 and the main frame 100, the top plate 110 is bent downward on all four sides to form a downward flange. When the top plate 110 is connected to the main frame 100, the four downward flanges abut against the outer side of the main frame 100, thereby quickly connecting and positioning the top plate 110 and the main frame 100.

[0033] As a specific structural embodiment of the main light-emitting component, the main light-emitting component includes a mounting frame 210, a Rayleigh scattering light guide plate 220, a Rayleigh scattering diffuser plate 230, and a first lamp body 240. The mounting frame 210 forms a cavity with an opening facing downwards. The Rayleigh scattering light guide plate 220 and the Rayleigh scattering diffuser plate 230 are arranged sequentially from top to bottom in the cavity. The first lamp body 240 is disposed on the side wall of the cavity, and multiple first lamp bodies 240 are arranged around the Rayleigh scattering light guide plate 220. Rayleigh scattering light guide plate 220 is a light guide plate made based on the Rayleigh scattering principle. Similarly, Rayleigh scattering diffuser plate 230 is a diffuser plate made based on the Rayleigh scattering principle. During operation, multiple first lamps 240 emit light into the Rayleigh scattering light guide plate 220. The light is guided through the Rayleigh scattering light guide plate 220 to the Rayleigh scattering diffuser plate 230, thereby achieving the function of downward light emission. By using the Rayleigh scattering principle and with the help of the Rayleigh scattering light guide plate 220 and the Rayleigh scattering diffuser plate 230, the light is processed so that the lamps can simulate the effect of a blue sky. This is different from traditional ship lighting, which only provides basic lighting. It optimizes the internal lighting environment of the ship from the perspective of optical principle application and component design.

[0034] When the main light source assembly is installed in the middle of the main frame 100, an opening can be directly made in the middle of the main frame 100, and then the main light source assembly can be installed on the side wall of the main frame 100 located at the opening. To improve the stability of the main light source assembly installation, a portion extending to the bottom of the main light source assembly can be provided on the main frame 100 to support the main light source assembly, thereby improving the stability of the main light source assembly installation. To further improve the sealing between the main light source assembly and the main frame 100, in this embodiment, the main frame 100 is provided with a second sealing groove corresponding to the position of the Rayleigh scattering diffuser plate 230. The second sealing groove extends around the Rayleigh scattering diffuser plate 230, and a second sealing ring 140 is provided in the second sealing groove. When the Rayleigh scattering diffuser plate 230 is installed in the middle of the main frame 100, the second sealing ring 140 abuts against the bottom side of the Rayleigh scattering diffuser plate 230, thus effectively blocking the assembly gap between the Rayleigh scattering diffuser plate 230 and the main frame 100, further improving the overall airtightness.

[0035] As a specific structural embodiment of the side-emitting light assembly, the side-emitting light assembly includes a second lamp body 310 and a diffuser 320. A mounting groove is provided on the bottom side of the main frame 100, extending around the main light-emitting assembly. The second lamp body 310 is disposed within the mounting groove, and the diffuser 320 is connected to the bottom side of the main frame 100 and covers the mounting groove. The second lamp body 310, located within the mounting groove, can emit light downwards through the diffuser 320, thereby achieving the side-emitting light function. In practical applications, multiple second lamp bodies 310 can be arranged around the mounting groove. The second lamp bodies 310 can be fixed to the main frame 100 by screws. The diffuser 320 can be snapped into the opening of the mounting groove. For example, a hook can be provided on one side of the mounting groove opening, allowing one side of the diffuser 320 to be snapped into the hook, while the other side of the diffuser 320 is pressed and positioned against the other side of the mounting groove opening, thus quickly fixing the diffuser 320 to the mounting groove.

[0036] To further improve the sealing performance between the diffuser shroud 320 and the mounting groove, in this embodiment, adhesive grooves 150 are respectively provided on both sides of the groove opening of the mounting groove on the bottom side of the main frame 100, and the two sides of the diffuser shroud 320 cover the two adhesive grooves 150 respectively. During installation, sealant can be applied into the adhesive grooves 150 on both sides of the groove opening of the mounting groove first, and then the diffuser shroud 320 can be connected to the main frame 100. At this time, the sealant can be used to connect the diffuser shroud 320 and the main frame 100, and can also be used to fill the assembly gap between the diffuser shroud 320 and the main frame 100, thereby improving the sealing performance of the connection.

[0037] To further prevent moisture from intruding into the main frame 100 and causing corrosion damage to the first lamp body 240 and the second lamp body 310, in this embodiment, a first nano-protective coating is provided on the sidewall of the cavity, covering the first lamp body 240. A second nano-protective coating is provided on the bottom of the mounting groove, covering the second lamp body 310. After the first lamp body 240 is installed on the sidewall of the cavity, the first nano-protective coating is applied to the sidewall of the cavity. Similarly, after the second lamp body 310 is installed on the bottom of the mounting groove, the second nano-protective coating is applied to the bottom of the mounting groove. The first and second nano-protective coatings can isolate the external environment from direct contact with the device, thereby preventing dust, moisture, chemicals, and other contaminants from entering the device and reducing damage and corrosion to electronic components. In practical applications, both the first and second nano-protective coatings can be fluorine surface nano-coatings.

[0038] Since the mounting slot surrounds the main light-emitting component, the corresponding diffuser 320 also surrounds the main light-emitting component. To improve the internal sealing, in this embodiment, the diffuser 320 is a one-piece molded structure. The one-piece molded diffuser 320 can effectively reduce the connection and assembly gaps, thereby reducing the intrusion of moisture into the main frame 100, reducing assembly steps, improving production efficiency, and reducing production costs.

[0039] In the above embodiments, the main frame 100 can be directly used for installation and fixation. However, to make the overall structure more stable, this utility model also includes an outer frame 400 in this embodiment. The outer frame 400 is fitted onto the outside of the main frame 100, and the bottom side of the outer frame 400 is provided with a support portion 410 extending to the bottom side of the diffuser shroud 320. After the outer frame 400 is fitted onto the outside of the main frame 100, its support portion 410 can press the diffuser shroud 320 upwards against the main frame 100, thereby making the connection of the diffuser shroud 320 more stable. The outer frame 400 itself can be used to install onto external structural components, such as on a ceiling. Since the connection point is located on the outer frame 400, damage to the structure of the main frame 100 is reduced, thereby further preventing moisture from entering from the connection point.

[0040] In some embodiments, a power supply box 510 is connected to the top side of the top plate 110, and a top cover 520 is connected to the top side of the power supply box 510. A third sealing ring 530 is provided between the top cover 520 and the power supply box 510. Electrical components such as power drives can be installed inside the power supply box 510. The top cover 520 seals the power supply box 510, and the third sealing ring 530 between the top cover 520 and the power supply box 510 increases the sealing performance between the two, which helps to prevent moisture from entering the power supply box 510 from the assembly gap between them.

[0041] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
