[0017] like Figure 1-3 As shown in the figure, this application provides an LED canopy light for ships, comprising: The lamp holder 1 includes an outer frame 11, an upper sealing device 12, a lower sealing device 13, and a back plate 14. The outer frame 11 is an integrally formed structure. The upper sealing device 12 and the lower sealing device 13 are respectively located on the upper and lower sides inside the outer frame 11. The back plate 14 is located on the inner side of the outer frame 11 and is connected to the upper sealing device 12. Light source assembly 2 is disposed inside the outer frame 11, the lower side of the light source assembly 2 is connected to the lower sealing device 13, and the upper side of the light source assembly 2 abuts against the back plate 14. A driving component 3 is disposed on the side of the back plate 14 facing away from the light source component 2 and is electrically connected to the light source component 2. The elastic buckle 4 comprises four elastic buckles, which are respectively disposed on both sides of the back of the outer frame 11.
[0018] This utility model discloses a marine LED canopy light, including a light frame 1, a light source assembly 2, a driving assembly 3, and elastic buckles 4. The light frame 1 includes an outer frame 11, an upper sealing device 12, a lower sealing device 13, and a back plate 14. The outer frame 11 is an integrally formed structure. Four elastic buckles 4 are respectively disposed on both sides of the back of the outer frame 11. The light source assembly 2 enters from the back of the outer frame 11. The lower sealing device 13 connects the bottom of the inner side of the outer frame 11 to the bottom of the light source assembly 2 to form a lower sealing connection. The upper sealing device 12 is connected to the back plate 14 to form an upper sealing connection. The outer frame 11 is fixed to the ceiling inside the ship by four elastic buckles 4 on its back. The LED canopy light for ships disclosed in this application has an integrally molded outer frame 11. The upper sealing device 12 and the back plate 14 cooperate to form an upper sealed connection for the light source assembly 2, and the light source assembly 2 cooperates with the lower sealing device 13 to form a lower sealed connection for the light source assembly 2, improving the stability and sealing of the canopy light assembly. Simultaneously, all four elastic buckles 4 are connected to the outer frame 11, further enhancing the stability of the canopy light installation.
[0019] The lower sealing device 13 includes an extension edge 131, a first annular protrusion 132, and a second annular protrusion 133. The extension edge 131 extends inward along the inner edge of the outer frame 11. The first annular protrusion 132 and the second annular protrusion 133 are coaxially disposed on the side of the extension edge 131 facing the light source assembly 2. The light source assembly 2 presses against the top of the first annular protrusion 132 and the second annular protrusion 133. The first annular protrusion 132, the second annular protrusion 133, and the extension edge 131 form a first sealing groove. The first extension edge 131 provides bottom support and limiting for the light source assembly 2. 2 and the second annular protrusion 133 support the light source assembly 2 and form a first sealing groove. Adhesive is filled into the first sealing groove to form a sealed connection between the light source assembly 2 and the lower sealing device 13. The first annular protrusion 132 extends inwardly along the inner edge of the extension edge 131. On the one hand, it increases the volume of the first sealing groove, which can accommodate more adhesive to bond with the light source assembly 2 and improve the stability of the bonding. On the other hand, the first annular protrusion 132 forms an inclined surface. When external humid gas comes into contact with the first annular protrusion 132, condensation droplets can slide outward along the first annular protrusion 132, further improving the sealing performance.
[0020] The upper sealing device 12 includes an inner frame 121, an auxiliary fixing mechanism 122, and a second sealing groove 123. The inner frame 121 is located inside the outer frame 11 and connected to it. The auxiliary fixing mechanism 122 connects the inner frame 121 and the back plate 14. The back plate 14 has an abutment edge 15 extending from its outer edge toward the light source assembly 2. The second sealing groove 123 is located on the top edge of the inner side of the outer frame 11. The inner side of the abutment edge 15 abuts against the outer side of the inner frame 121. The back plate 121... 4. The abutment edge 15 is inserted into the second sealing groove 123 and abuts against the outer side of the inner frame 121 to form a bent channel. At the same time, glue is filled into the second sealing groove 123. The outer side of the abutment edge 15 and the other side of the second sealing groove 123 are glued together to form a double sealing structure with better sealing effect. In addition, when the back plate 14 is snapped onto the inner frame 121, the inner frame 121 and the back plate 14 are initially fixed by the auxiliary fixing mechanism 122 to prevent the back plate 14 from shaking or shifting during the sealing process, which would affect the sealing effect.
[0021] The inner frame 121 includes a U-shaped frame with its opening facing the back plate 14. The auxiliary fixing mechanism 122 includes multiple screw holes 124, multiple screws 125, multiple first annular grooves 126, and multiple second annular grooves 127. The multiple first annular grooves 126 are located on one side of the U-shaped frame along the height direction of the outer frame 11, and the multiple second annular grooves 127 are located on the other side of the U-shaped frame along the height direction of the outer frame 11. The multiple screw holes 124 surround the edge of the back plate 14. The screws 125 and the screw holes 124 correspond one-to-one and slide in each other. The two sides of each screw 125 are threadedly connected to the first annular grooves 126 and the second annular grooves 127 respectively. When the screw 125 is screwed in, the threads on its circumference are screwed into the first annular grooves 126 and the second annular grooves 127 from top to bottom. Before the glue seal, it provides preliminary fixing and limiting for the back plate 14 and the inner frame 121. After the glue seal is completed, it forms a double fixing structure with the glue seal, which improves the stability of the assembly.
[0022] In this embodiment, the nut of each screw 125 is encapsulated with sealant; each elastic buckle 4 is connected to the outer frame 11 by rivets to prevent the connection from loosening due to the swaying of the ship.
[0023] The light source assembly 2 includes a light strip 21 and a cotton pad 22, a reflective paper 23, a light guide plate 24, and a diffuser plate 25 arranged sequentially from top to bottom. The light strip 21 is located on the inner side of the inner frame 121, and the light source side of the light strip 21 abuts against the outer periphery of the reflective paper 23. The large light guiding and reflection diffusion between the reflective paper 23, the light guide plate 24, and the diffuser plate 25 helps to improve the illumination range. The cotton pad 22 provides support and cushioning between the reflective paper 23 and the back plate 14.
[0024] The outer frame 11 has a third annular protrusion 16 on its outer periphery. On the one hand, when the canopy light is installed in the ceiling of the ship, the third annular protrusion 16 fills the gap between the outer frame 11 and the ceiling of the ship, reduces shaking, improves sealing, and reduces water vapor corrosion of the elastic buckle 4. On the other hand, it positions and limits the elastic buckle 4 before it is installed, preventing displacement during assembly.
[0025] The outer frame 11 has an inclined surface 17 on its outer periphery. When external humid gas comes into contact with the inclined surface 17, condensed water droplets can slide outward along the inclined surface 17.
[0026] The above description provides one or more embodiments in conjunction with specific content, and does not imply that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to or identical to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
