[0030] From the above, the fixed frame 400 is used to install to the structure surface of the external device, such as the ceiling, the lighting body is used to realize the main lighting function, the bottom side of the fixed frame 400 has the supporting part 410 that can support the lighting body, prevent the lighting body from falling from the fixed frame 400, and the connecting groove 160 for connecting with the fixed frame 400 is arranged on the outer side of the lighting body, at this time, the connecting accessory 700 is directly passed through the fixed frame 400 and connected in the connecting groove 160, the relative fixation of the fixed frame 400 and the lighting body is realized, similarly, the snap spring 600 is also directly connected in the connecting groove 160, so that the structure of the lighting body is not damaged, the air tightness inside the lighting body is guaranteed, when installing, the movable end of the snap spring 600 is elastically rotated away from the installation part 420, so that the movable end of the snap spring 600 is pressed against the inner top side of the ceiling, and the supporting part 410 is abutted to the inner bottom side of the ceiling, because the movable end of the snap spring 600 has the trend of elastically restoring to the direction close to the installation part 420, the supporting part 410 can be kept pressed and positioned on the inner top side of the ceiling, so that the installation of the whole lighting device is realized, therefore, the connecting groove 160 for connecting fixation is arranged on the outer side of the lighting body, the operation of opening holes on the surface is reduced, the air tightness inside the lighting body is effectively guaranteed, and the fixed frame 400 and the snap spring 600 are used for installation and fixation, the stable installation of the whole is realized, and the overall use reliability is improved.

[0031] The connecting fitting 700 can be directly connected by screws or the like, but in the use environment of a ship or the like, the ship itself generates a large vibration, and the vibration is conducted from the fixed frame 400 to the lighting main body through the connecting fitting 700. Therefore, in order to reduce the transmission of the vibration to the lighting main body through the connecting fitting 700, in the present embodiment, the connecting fitting 700 includes an outer sleeve 710, an inner sleeve 720, limiting balls 730, and a separation piece. One end of the outer sleeve 710 is connected to the connecting groove 160, and the other end of the outer sleeve 710 has a plurality of limiting balls 730 accommodated in the inner side in the circumferential direction. One end of the inner sleeve 720 is connected to the fixed frame 400, and the other end of the inner sleeve 720 extends into the outer sleeve 710. The plurality of limiting balls 730 abut against the outer side of the inner sleeve 720, respectively. The separation piece is located between the outer sleeve 710 and the inner sleeve 720, and has a tendency to separate the outer sleeve 710 and the inner sleeve 720 from each other. The separation piece causes the end of the inner sleeve 720 to extend into the outer sleeve 710, and the two are located in a tendency to move away from each other to the end of the stroke. At this time, the inner sleeve 720 can further move into the outer sleeve 710, that is, a space region capable of buffering the vibration is formed. The inner sleeve 720 is limited in the circumferential direction by the plurality of limiting balls 730, which can reduce the contact area between the outer sleeve 710 and the inner sleeve 720, thereby reducing the transmission of the vibration. The vibration is unloaded by the limiting ball 730 on one side. When the structure of the external device transmits the vibration to the fixed frame 400, the vibration is transmitted in the transverse direction to the inner sleeve 720. Since the outer sleeve 710 and the inner sleeve 720 have a space that can move relative to each other and buffer, the transverse vibration transmitted to the lighting main body can be effectively reduced. The vertical vibration is transmitted to the inner sleeve 720, and the lighting main body is supported by the support portion 410, so that the lighting main body will not fall from the fixed frame 400. The plurality of limiting balls 730 abut against the outer side of the inner sleeve 720 to limit the movement. When the limiting ball 730 on one side is subjected to a large pressure, the elastic deformation of the limiting ball 730 itself can reduce the transmission of the vibration. Thus, the transmission of the vibration from the fixed frame 400 to the lighting main body can be greatly reduced, thereby improving the stability of the internal structure of the lighting main body and prolonging the overall service life.

[0032] The separation piece can use a structure having an elastic deformation capability such as a spring or rubber. In order to further reduce the transmission of the vibration, in the present embodiment, the separation piece includes a first magnet 741 connected to the outer sleeve 710 and a second magnet 742 connected to the inner sleeve 720. The first magnet 741 and the second magnet 742 repel each other. The magnetic field of the first magnet 741 and the second magnet 742 causes the end of the inner sleeve 720 to extend into the outer sleeve 710, and the two are located in a tendency to move away from each other to the end of the stroke. The inner sleeve 720 can move into the outer sleeve 710.

[0033] In order to facilitate the installation of the connecting accessory 700 between the fixing frame 400 and the lighting body, in this embodiment, the outer sleeve 710 is threadedly connected to the connecting groove 160, and a rotation-stopping channel 711 is provided on the inner side of the end of the outer sleeve 710 away from the inner sleeve 720. The end of the inner sleeve 720 close to the outer sleeve 710 is a rotation-stopping part, and the rotation-stopping part can cooperate with or exit the rotation-stopping channel 711. In actual application, the rotation-stopping part can be a multi-edge portion formed on the outer side of the end of the inner sleeve 720, for example, The cross-section of the anti-rotation part can be a triangle, a rectangle or a pentagon, etc. Correspondingly, the limiting ball 730 also abuts against the outer surface of the anti-rotation part. For example, when the cross-section of the anti-rotation part is a pentagon, the number of limiting balls 730 is also five, and the five limiting balls 730 respectively abut against the five side surfaces of the anti-rotation part. The end of the inner sleeve 720 away from the outer sleeve 710 is formed with a connecting section 721, and the outer diameter of the connecting section 721 is smaller than the outer diameter of the inner sleeve 720. The connecting section 721 passes through the fixed frame 400 and is connected to a nut 750. The outer sleeve 710 is connected to the connecting groove 160 through a thread, which can improve the stability of being installed in the connecting groove 160. When the outer sleeve 710 needs to be connected to the connecting groove 160, the inner sleeve 720 is pressed into the outer sleeve 710 so that the anti-rotation part is connected to the anti-rotation channel 711. At this time, rotating the inner sleeve 720 can drive the outer sleeve 710 to rotate synchronously, thereby tightening and fixing the outer sleeve 710 in the connecting groove 160. After completing the connection of the outer sleeve 710, the pressure on the inner sleeve 720 is removed, and the separator makes the outer sleeve 710 and the inner sleeve 720 move away from each other, so that the end face of the inner sleeve 720 is against the inner side of the fixed frame 400, and the connecting section 721 passes through the fixed frame 400, and the nut 750 is connected to the part of the connecting section 721 passing through the fixed frame 400, thereby fixing the inner sleeve 720 on the fixed frame 400.

[0034] In the above embodiment, the limiting balls 730 can be metal balls. Metal itself has a certain elastic deformation ability. In order to improve the buffering ability of the limiting balls 730 against unilateral vibration, in this embodiment, the plurality of limiting balls 730 are each made of an elastic material. For example, the limiting balls 730 can be made of rubber. When vibration is transmitted from the inner sleeve 720 to the limiting balls 730, the inner sleeve 720 moves relative to one side of the outer sleeve 710, causing the limiting balls 730 on that side to be squeezed. At this time, the elastic limiting balls 730 can buffer and reduce the vibration, thereby effectively reducing the vibration transmitted to the lighting body.

[0035] Furthermore, a cushion is provided between the support portion 410 and the lighting body. The cushion mainly provides elastic cushioning and can be made of rubber or other materials. The cushion can further reduce the vibration transmitted from the support portion 410 to the lighting body, thereby further improving the structural stability of the lighting body.

The top plate 110 is arranged on the top side of the main frame 100, the middle of the main frame 100 is closed by the top plate 110, the main light-emitting assembly is arranged in the middle of the main frame 100, and the side light-emitting assembly is arranged around the main light-emitting assembly. During work, one of the main light-emitting assembly or the side light-emitting assembly can be selected to emit light downward, or the main light-emitting assembly and the side light-emitting assembly can be selected to emit light downward at the same time, which enriches the lighting function. In addition, the buffer layer 120 is arranged between the main light-emitting assembly and the top plate 110, when the vibration of the fixed frame 400 is transmitted to the main frame 100, the vibration transmitted to the main light-emitting assembly can be weakened again by the buffer layer 120, thereby reducing the influence on the main light-emitting assembly. In this way, the diversity and flexibility of light emission can be improved, different use scenarios can be better met, structural fatigue and damage caused by ship vibration can be reduced, and use stability can be improved.

[0037] The environment inside the ship is humid, and there is a large amount of water vapor in the air. In order to prevent water vapor from entering the inside of the main frame 100, in the embodiment, the top side of the main frame 100 is provided with a first sealing groove, the first sealing groove extends around the main light-emitting assembly, and the first sealing groove is provided with a first sealing ring 130. 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 is beneficial to prevent water vapor from entering inward from the assembly gap between the top plate 110 and the main frame 100.

[0038] In order to improve the convenience of connecting the top plate 110 and the main frame 100, the top plate 110 is bent downward on four sides to form a downward turning edge. When the top plate 110 is connected to the main frame 100, the four downward turning edges abut against the outer side of the main frame 100 respectively, so as to quickly connect and position the top plate 110 and the main frame 100.

[0039] As a specific structural embodiment of the main light-emitting assembly, the main light-emitting assembly comprises a mounting frame 210, a Rayleigh scattering light guide plate 220, a Rayleigh scattering diffusion plate 230 and a first lamp body 240. The mounting frame 210 is formed with a cavity with an opening downward. The Rayleigh scattering light guide plate 220 and the Rayleigh scattering diffusion plate 230 are sequentially arranged in the cavity from top to bottom. The first lamp body 240 is arranged on the side wall of the cavity, and a plurality of first lamp bodies 240 are arranged around the Rayleigh scattering light guide plate 220. The Rayleigh scattering light guide plate 220 is a light guide plate made based on the Rayleigh scattering principle. Similarly, the Rayleigh scattering diffusion plate 230 is a diffusion plate made based on the Rayleigh scattering principle. When working, the plurality of first lamp bodies 240 emit light to the Rayleigh scattering light guide plate 220, and the light is guided to the Rayleigh scattering diffusion plate 230 through the Rayleigh scattering light guide plate 220, thereby realizing the function of downward light emission. By using the Rayleigh scattering principle and processing the light by means of the Rayleigh scattering light guide plate 220 and the Rayleigh scattering diffusion plate 230, the lamp can simulate the effect of a blue sky. Unlike traditional ship lighting which only provides basic lighting, the application realizes the optimization of the ship interior lighting environment from the application of optical principles and the design of components.

[0040] When the main light source assembly is installed in the middle part of the main surrounding frame 100, a hole can be directly formed in the middle part of the main surrounding frame 100, and then the main light source assembly is installed on the side wall of the main surrounding frame 100 at the position of the hole. In order to improve the stability of the installation of the main light source assembly, a part extending to the bottom side of the main light source assembly can be arranged on the main surrounding frame 100, which is used to support the main light source assembly, thereby improving the stability of the installation of the main light source assembly. In order to further improve the sealing between the main light source assembly and the main surrounding frame 100, in this embodiment, the main surrounding frame 100 is provided with a second sealing groove corresponding to the position of the Rayleigh scattering diffusion plate 230, the second sealing groove extends around the Rayleigh scattering diffusion plate 230, and a second sealing ring 140 is arranged in the second sealing groove. When the Rayleigh scattering diffusion plate 230 is installed in the middle part of the main surrounding frame 100, the second sealing ring 140 abuts against the bottom side of the Rayleigh scattering diffusion plate 230, so as to effectively block the assembly gap between the Rayleigh scattering diffusion plate 230 and the main surrounding frame 100, and further improve the overall air tightness.

[0041] As a specific structural embodiment of the side light-emitting assembly, the side light-emitting assembly comprises the second lamp body 310 and the diffusion cover 320, the bottom side of the main surrounding frame 100 is provided with a mounting groove, the mounting groove extends around the main light-emitting assembly, the second lamp body 310 is arranged in the mounting groove, and the diffusion cover 320 is connected to the bottom side of the main surrounding frame 100 and covers the mounting groove. The second lamp body 310 is arranged in the mounting groove and can emit light downward through the diffusion cover 320, thereby realizing the side light-emitting function. In actual application, a plurality of second lamp bodies 310 can be arranged around the mounting groove, the second lamp body 310 can be fixed to the main surrounding frame 100 by screwing, and the diffusion cover 320 can be connected to the slot opening position of the mounting groove in a buckling manner. For example, a clamping hook can be arranged at one side of the slot opening of the mounting groove, one side of the diffusion cover 320 is clamped at the clamping hook, and the other side of the diffusion cover 320 is pressed against the other side of the slot opening of the mounting groove, thereby quickly fixing the diffusion cover 320 to the mounting groove.

[0042] In order to further improve the connection sealing performance between the diffusion cover 320 and the mounting groove, in the embodiment, the bottom side of the main surrounding frame 100 is provided with a glue groove 150 at the slot opening position on both sides of the mounting groove, and the two sides of the diffusion cover 320 cover the two glue grooves 150, respectively. During installation, sealing glue is first screwed into the glue grooves 150 on both sides of the slot opening of the mounting groove, and then the diffusion cover 320 is connected to the main surrounding frame 100. At this time, the sealing glue can be used to connect the diffusion cover 320 and the main surrounding frame 100 to each other and can also be used to fill the assembly gap between the diffusion cover 320 and the main surrounding frame 100, thereby improving the sealing performance of the connection between the two.

[0043] In order to further prevent water vapor from entering the main surrounding frame 100 and causing corrosion and damage to the first lamp body 240 and the second lamp body 310, in the embodiment, the side wall of the cavity is provided with a first nano protective coating, the first nano protective coating covers the first lamp body 240, the bottom of the mounting groove is provided with a second nano protective coating, and the second nano protective coating covers the second lamp body 310.

Similarly, after the second lamp body 310 is installed on the bottom of the mounting groove, the second nano protective coating is coated on the bottom of the mounting groove. The first nano protective coating and the second nano protective coating can isolate the direct contact between the external environment and the device, thereby preventing dust, moisture, chemicals and other pollutants from entering the interior of the device and reducing the damage and corrosion of electronic components. In actual application, the first nano protective coating and the second nano protective coating can both use fluorine surface nano coating.

[0044] Since the installation groove is arranged around the main light-emitting component, the diffuser cover 320 is also arranged around the main light-emitting component. In order to improve the sealing performance, the diffuser cover 320 is integrally formed in the embodiment. The integrally formed diffuser cover 320 can effectively reduce the connection assembly gap, thereby reducing the intrusion of water vapor into the interior of the main frame 100, reducing the assembly steps, improving the production efficiency, and reducing the production cost.
