Description

Technical Field

[0001] This utility model relates to the field of floodlight technology, and in particular to a floodlight structure. Background Technology

[0002] Floodlights are lighting fixtures that project light in a directional manner and are widely used in many scenarios. In industrial settings, floodlights are widely used in hazardous environments such as oil extraction, refining, chemical, and military industries, as well as on offshore oil platforms and tankers, for long-distance floodlighting and street lighting; they are also suitable for lighting various factory areas and medium- to high-ceilinged factory buildings. In commercial settings, floodlights are suitable for skyscrapers, stadiums, entertainment venues, large plazas, golf courses, shopping malls, bridges, docks, television towers, and sculptures, and can be used to illuminate building facades, outline landscape features, and highlight advertising signs.

[0003] The existing floodlight structure has the following disadvantages: 1. In the existing light-transmitting lamp structure, the reflector installation part inside the lamp housing has a complex structural design. During assembly, it is inconvenient to install and fix the reflector, and during disassembly, it is inconvenient to remove it from the lamp housing; 2. The complex structural design of the lamp housing part increases the number of overall components, making it inconvenient to disassemble and assemble.

[0004] Therefore, how to provide a floodlight structure with a simpler and more reasonable structural design, which can better install and fix the light guide cover, has fewer components, and is easier to disassemble and assemble, has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to provide a floodlight structure with a simpler and more reasonable structural design, which can better install and fix the light guide cover, has fewer components, and is easier to disassemble and assemble.

[0006] To achieve the above objectives, this utility model provides a floodlight structure, including a lamp housing with an overall flat rectangular box design and an open bottom. A first mounting cavity is formed on one side of the lamp housing to house electrical components; a second mounting cavity is formed on the other side of the lamp housing to house a horizontally arranged lamp plate; a horizontal faceplate is mounted on the open end of the lamp housing; a reflector with an overall truncated quadrangular cylindrical structure is provided between the lamp plate and the faceplate, and a mounting and fixing structure is provided between the lower end of the reflector and the faceplate; the mounting and fixing structure includes a docking cavity with an overall flat rectangular structure set on the inner surface of the faceplate, the lower end of the reflector being bent horizontally outward to form a horizontal flange, the outer side of the horizontal flange being bent upward to form a vertical flange, and the upper end of the vertical flange being bent horizontally outward to form an overlapping flange; the lower end of the reflector is inserted into the docking cavity, and the outer circumferential surface of the vertical flange is supported against the inner circumferential surface of the docking cavity, while the overlapping flange is supported against the inner surface of the faceplate.

[0007] In this way, the installation and fixing structure of the floodlight described above is simpler and more reasonable. By designing a docking cavity on the faceplate, and integrally forming horizontal, vertical, and overlapping flanges on the lower end of the reflector, the lower end of the reflector is inserted into the docking cavity. The outer circumference of the vertical flange rests against the inner circumference of the docking cavity, and the overlapping flange rests against the inner surface of the faceplate, thus positioning and installing the reflector. Compared to designing the reflector mounting structure on the lamp housing, this structure is simpler and easier to manufacture. It is also easier to assemble and disassemble.

[0008] Furthermore, the face mask is made of a transparent material.

[0009] As an optimization, the distance between the lower side of the overlapping flange and the lower side of the horizontal flange is set to be less than the depth of the docking cavity, and the lower side of the horizontal flange is spaced apart from the bottom surface of the docking cavity.

[0010] In this way, by limiting the dimensions of the horizontal flange, vertical flange, and overlapping flange, the overall structural design becomes simpler and more reasonable, ensuring better installation and facilitating assembly.

[0011] As an optimization, the reflector is designed as a frustum-shaped structure with a smaller upper end and a larger lower end. The reflector includes a cylindrical part at the lower end and a docking part at the upper end. The docking part includes a horizontal plate integrally formed on the upper end of the cylindrical part. On the horizontal plate, there are round holes corresponding to the lamp beads on the lamp board. Each round hole is provided with a docking cylinder. The docking cylinder is set with a smaller upper diameter and a larger lower diameter, so that the upper end of each docking cylinder abuts and is supported on the lower surface of the lamp board.

[0012] In this way, the reflector's structural design is simpler and more reasonable. The connecting tube and the LED beads correspond one-to-one, which can reflect the light emitted by the LED beads once. The lower tube can reflect the light emitted by multiple LED beads again, thus making the overall lighting effect of the lamp better.

[0013] As an optimization, the lamp beads are LED lamp beads.

[0014] Thus, using LED beads has an energy-saving effect.

[0015] As an optimization, the open end of the lamp housing is bent outward horizontally to form a rectangular mounting flange. The inner edge of the lower surface of the mounting flange is recessed inward to form a rectangular overlapping step surface, and the upper edge of the faceplate overlaps on the overlapping step surface. A clamping frame with a rectangular frame structure is provided below the mounting flange, and the inner side of the upper surface of the clamping frame forms a clamping surface that is attached to and supported on the lower edge of the faceplate. Multiple screw holes are provided at intervals along the contour of the mounting flange, and connecting screws are arranged therein, with the connecting screws threaded onto the clamping frame.

[0016] In this way, by setting an installation flange on the lamp housing and a corresponding clamping frame, the faceplate can be pressed and installed onto the lamp housing more effectively, and disassembly and assembly are more convenient. Furthermore, the faceplate can cover the entire opening of the lamp housing, saving components compared to designing two separate covers, one for the first mounting cavity and one for the second mounting cavity.

[0017] Furthermore, a ring-shaped clearance groove is provided on the overlapping step surface.

[0018] As an optimization, the clamping frame includes a clamping plate, the inner edge of which is bent upward to form an inner support bent edge, and the distal surface of the inner support bent edge forms the clamping surface.

[0019] This makes the structure of the clamping frame simpler and allows for better clamping of the faceplate onto the lamp housing.

[0020] Furthermore, a connecting post is provided on the clamping plate, each corresponding to a screw hole, protruding upwards. A threaded hole is provided on the connecting post, and the threaded connection of each connecting screw is disposed in the threaded hole.

[0021] As an optimization, the outer side of the mounting flange is bent downwards and outwards to form an inclined bent edge, and the outer side of the inclined bent edge is bent outwards horizontally to form a horizontal bent edge; the outer edge of the clamping plate is bent upwards to form an outer support bent edge, and the upper side of the outer support bent edge is attached to the lower surface of the horizontal bent edge.

[0022] This more rational structural design allows the clamping frame to better clamp the cover plate and provide better clamping force.

[0023] Furthermore, the outer side of the horizontal bend extends vertically downward, tilts upward towards the outside, and then bends vertically upward again to form a reinforcing section.

[0024] As an optimization, the bottom surface of one side of the lamp housing is drawn upward to form the first mounting cavity, and the electrical part structure includes a battery installed in the first mounting cavity; two through holes with a wall thickness are provided on the lamp housing and corresponding to the first mounting cavity.

[0025] In this way, the overall structure of the lamp housing is simpler and more reasonable, which can better separate the battery and the lamp panel and better prevent the heat of the two from affecting each other.

[0026] As an optimization, the bottom surface inside the lamp housing is drawn upwards on both sides of the lamp plate to form an arched part on the upper surface of the lamp housing, and a number of heat dissipation teeth are provided between the two arched parts on the upper surface of the lamp housing.

[0027] This makes the overall lamp housing design more reasonable, resulting in better structural strength and better heat dissipation for the lamp panel.

[0028] Furthermore, mounting cylinders are provided on both sides of the rear end of the lamp housing, each protruding horizontally outward, and mounting holes are provided at the outer ends of the mounting cylinders.

[0029] In summary, the above-mentioned floodlight structure has the advantages of simpler and more reasonable structural design, easier installation and fixation of the light guide cover, fewer components, and easier disassembly and assembly. Attached Figure Description

[0040] like Figures 1 to 9 As shown, a floodlight structure includes a lamp housing 1 with an overall flat rectangular box design and an open bottom. A first mounting cavity 2 is formed on one side of the lamp housing and an electrical component structure is installed therein. A second mounting cavity 3 is formed on the other side of the lamp housing and a horizontally arranged lamp plate 4 is installed therein. A horizontal faceplate 5 is installed at the open end of the lamp housing. A reflector 6 with an overall truncated quadrangular cylindrical structure is provided between the lamp plate and the faceplate. An installation and fixing structure is provided between the lower end of the reflector and the faceplate. The installation and fixing structure includes a docking cavity 7 with an overall flat rectangular structure set on the inner surface of the faceplate. The lower end of the reflector is bent horizontally outward to form a horizontal flange 8. The outer side of the horizontal flange is bent upward to form a vertical flange 9, and the upper end of the vertical flange is bent horizontally outward to form an overlapping flange 10. The lower end of the reflector is inserted into the docking cavity, and the outer circumferential surface of the vertical flange is supported against the inner circumferential surface of the docking cavity, and the overlapping flange is supported against the inner surface of the faceplate.

[0041] In this way, the installation and fixing structure of the floodlight described above is simpler and more reasonable. By designing a docking cavity on the faceplate, and integrally forming horizontal, vertical, and overlapping flanges on the lower end of the reflector, the lower end of the reflector is inserted into the docking cavity. The outer circumference of the vertical flange rests against the inner circumference of the docking cavity, and the overlapping flange rests against the inner surface of the faceplate, thus positioning and installing the reflector. Compared to designing the reflector mounting structure on the lamp housing, this structure is simpler and easier to manufacture. It is also easier to assemble and disassemble.

[0042] Furthermore, the face mask is made of a transparent material.

[0043] In this specific embodiment, the distance between the lower side of the overlapping flange and the lower side of the horizontal flange is less than the depth of the docking cavity, and the lower side of the horizontal flange is spaced apart from the bottom surface of the docking cavity.

[0044] In this way, by limiting the dimensions of the horizontal flange, vertical flange, and overlapping flange, the overall structural design becomes simpler and more reasonable, ensuring better installation and facilitating assembly.

[0045] In this specific embodiment, the reflector is designed as a frustum-shaped structure with a smaller upper end and a larger lower end. The reflector includes a cylindrical part 11 at the lower end and a docking part at the upper end. The docking part includes a horizontal plate 12 integrally formed on the upper end of the cylindrical part. A circular hole is provided on the horizontal plate and corresponding to the lamp beads 13 on the lamp board. A docking cylinder 14 is provided corresponding to each circular hole. The docking cylinder is designed with a smaller upper diameter and a larger lower diameter, so that the upper end of the docking cylinder abuts and is supported on the lower surface of the lamp board.

[0046] In this way, the reflector's structural design is simpler and more reasonable. The connecting tube and the LED beads correspond one-to-one, which can reflect the light emitted by the LED beads once. The lower tube can reflect the light emitted by multiple LED beads again, thus making the overall lighting effect of the lamp better.

[0047] In this specific embodiment, the lamp bead is an LED lamp bead.

[0048] Thus, using LED beads has an energy-saving effect.

[0049] In this specific embodiment, the open end of the lamp housing is bent outward horizontally to form a rectangular mounting flange 15. The inner edge of the lower surface of the mounting flange is recessed inward to form a rectangular overlapping step surface 16, and the upper edge of the faceplate overlaps on the overlapping step surface. A clamping frame 17 with a rectangular frame structure is provided below the mounting flange, and the inner side of the upper surface of the clamping frame forms a clamping surface and is supported against the lower edge of the faceplate. Multiple screw holes are provided on the mounting flange at intervals along its contour direction, and connecting screws 18 are arranged thereon, and the connecting screws are threadedly connected to the clamping frame.

[0050] In this way, by setting an installation flange on the lamp housing and a corresponding clamping frame, the faceplate can be pressed and installed onto the lamp housing more effectively, and disassembly and assembly are more convenient. Furthermore, the faceplate can cover the entire opening of the lamp housing, saving components compared to designing two separate covers, one for the first mounting cavity and one for the second mounting cavity.

[0051] Furthermore, a ring-shaped clearance groove 19 is provided on the overlapping step surface.

[0052] In this specific embodiment, the clamping frame includes a clamping plate 20, the inner edge of the clamping plate is bent upward to form an inner support bent edge 21, and the distal surface of the inner support bent edge forms the clamping surface.

[0053] This makes the structure of the clamping frame simpler and allows for better clamping of the faceplate onto the lamp housing.

[0054] Furthermore, a connecting post 22 is provided on the clamping plate, each corresponding to a screw hole, protruding upwards. A threaded hole is provided on the connecting post, and the threaded connection of each connecting screw is disposed in the threaded hole.

[0055] In this specific embodiment, the outer side of the mounting flange is bent downwards and outwards to form an inclined bent edge 23, and the outer side of the inclined bent edge is bent outwards horizontally to form a horizontal bent edge 24; the outer edge of the clamping plate is bent upwards and outwards to form an outer support bent edge 25, and the upper side of the outer support bent edge is attached to the lower surface of the horizontal bent edge.

[0056] This more rational structural design allows the clamping frame to better clamp the cover plate and provide better clamping force.

[0057] Furthermore, the outer side of the horizontal bend extends vertically downward, tilts upward towards the outside, and then bends vertically upward again to form a reinforcing section.

[0058] In this specific embodiment, the bottom side of the lamp housing is drawn upward to form the first mounting cavity. The electrical structure includes a battery 26 installed in the first mounting cavity. Two through holes 27, which are formed through the wall thickness, are provided on the lamp housing and corresponding to the first mounting cavity.

[0059] In this way, the overall structure of the lamp housing is simpler and more reasonable, which can better separate the battery and the lamp panel and better prevent the heat of the two from affecting each other.

[0060] In this specific embodiment, the bottom surface inside the lamp housing and the two outer sides of the lamp plate are each pulled upward to form an arched portion 28 on the upper surface of the lamp housing, and a plurality of heat dissipation toothed plates 29 are provided between the two arched portions on the upper surface of the lamp housing.

[0061] This makes the overall lamp housing design more reasonable, resulting in better structural strength and better heat dissipation for the lamp panel.

[0062] Furthermore, mounting cylinders 30 are provided on both sides of the rear end of the lamp housing, each protruding horizontally outward, and mounting holes are provided on the outer end of the mounting cylinders.

[0063] In summary, the above-mentioned floodlight structure has the advantages of simpler and more reasonable structural design, easier installation and fixation of the light guide cover, fewer components, and easier disassembly and assembly.

[0064] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
