Description

Technical Field

[0001] This invention relates to an outdoor projection device. Background Technology

[0002] Light shows are a common way to express the nighttime lighting of urban buildings and landscapes. Through cool and dynamic light and shadow and dreamlike and gorgeous effects, light shows can win the hearts of many people. Light shows can not only help scenic spots and city centers enhance the attractiveness of landmark buildings and core areas, and increase the artistic beauty and cultural heritage of regional scenic spots, but also enhance the popularity of cities or core scenic spots. Light shows typically require a venue, which can be categorized into natural venues and artificial ones. Natural venues fully utilize natural geographical features to create different types of light shows. Artificial venues, on the other hand, are created due to the lack of natural geographical conditions. In artificially created light shows, most lamps and floodlights are individually equipped with driver sources, which are controlled to change the angle or position of the lamps and illuminate the surrounding environment. For example, patents CN202221948572.9, entitled "A Solderless Wire-Free Split-Assembly Outdoor Waterproof Floodlight," and CN202221933621.1, entitled "An Outdoor Floodlight for Easy Disassembly and Maintenance," both use single lamps. To achieve large-area projection, multiple floodlights are needed, resulting in overly complex equipment and huge costs. The setup and disassembly of lamps in outdoor light shows are laborious and time-consuming. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an outdoor floodlighting device with a novel structure. This floodlighting device can change the angle and position of multiple sets of lamps through a single drive to illuminate the surrounding environment and is applicable to a variety of places.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an outdoor floodlighting device, comprising a base, a first housing on the base, a driving component and a support frame inside the first housing, a first rotating component movably connected to the center of the support frame, the bottom of the first rotating component penetrating the center of the support frame and connected to the driving component, a plurality of second rotating components evenly distributed along the length of the first rotating component, the first rotating component and the second rotating components rotating synchronously, the second rotating components slidingly connected to the upper end of the first housing, the adjacent second rotating components being connected through the second housing, each of the first rotating components being provided with an angle adjustment component, and each of the second rotating components being provided with a plurality of lamps, the angle adjustment component controlling the illumination angle of the lamps.

[0005] Furthermore, the first rotating component includes a rotating rod with multiple main gears evenly distributed and fixedly connected to it. The end of the rotating rod is connected to a driving component, which is a motor. The motor's output shaft is connected to the rotating rod. When the motor starts, the output shaft rotates, causing the rotating rod to rotate. The rotating rod's rotation causes the main gears to rotate, which in turn drives the second rotating component to rotate. A through groove is provided on the side wall of the rotating rod, and an angle adjustment component is provided at the through groove. The side wall of the through groove is fixedly connected to the angle adjustment component.

[0006] Furthermore, a first bevel gear is sleeved on the lower end of the rotating rod, the first bevel gear is perpendicularly meshed with a second bevel gear, the head of the second bevel gear is movably connected to one end of the fixed rod, and the other end of the fixed rod is fixedly connected to the rotating rod.

[0007] Furthermore, an extended arc-shaped plate is fixed to the upper end of the rotating rod, and a cavity is provided between the arc-shaped plates for placing the ceiling light.

[0008] Furthermore, the second rotating component includes a driven gear that meshes with the main gear. The driven gear has an upper rail on its upper end face and a lower rail on its lower end face. The first housing has a connecting ball on its upper end face corresponding to the lower rail. The connecting ball is movably connected within the lower rail. The second housing has a connecting ball on its upper end face and a support column on its lower end face. The connecting ball on the upper end face of the second housing is movably connected to the lower rail of the previous driven gear, and the support column on the lower end face of the second housing is movably connected to the upper rail of the next driven gear.

[0009] Furthermore, the second rotating frame also includes a cylindrical housing, which is engaged with the driven gear. The cylindrical housing is hollow inside, and symmetrical openings are provided on the side of the cylindrical housing. A frame extends inward from the sidewall of the opening, and the frame is used to place the lamp.

[0010] Furthermore, the angle adjustment components are connected by a first transmission component. Each angle adjustment component includes multiple sets of first gears vertically arranged in the through slot. The adjacent first gears mesh with each other. Each first gear is connected to the through slot via a connecting shaft. Each lamp corresponds to a first gear. The rotation of the first gear drives the lamp to rotate. One end of the connecting shaft of the initial first gear is connected to a main transmission component. The main transmission component passes through the main gear and is connected to the second bevel gear. When the main transmission component is activated, the initial first gear rotates, the meshing first gears rotate, and simultaneously drive the other angle adjustment components to start through the first transmission component.

[0011] Furthermore, the angle adjustment components are connected by a first transmission component. Each angle adjustment component includes a first gear and a second gear vertically arranged in the through slot. The first gear and the second gear are spaced apart vertically. Each lamp corresponds to a first gear and a second gear. Both the first gear and the second gear are connected to the through slot via a connecting shaft. A second transmission component is provided at one end of the connecting shaft of the first gear. The second transmission component is connected to the connecting shaft of the second gear. The other end of the connecting shaft of the first gear is connected to a main transmission component. The main transmission component passes through the main gear and is connected to the second bevel gear. When the main transmission component is activated, the first gear rotates, and the second transmission component drives the second gear to rotate. Simultaneously, the other angle adjustment components are activated through the first transmission component.

[0012] Furthermore, both the lamp and the ceiling light include a spherical shell, which is connected to the cavity via a movable shaft. The spherical shell has an opening, and a lamp bead is installed at the opening. A third gear meshing with a first gear and a second gear is provided around the spherical shell. When the first gear and the second gear rotate, the spherical shell carries the lamp bead to form illumination at different angles.

[0013] Furthermore, the main transmission component, the first transmission component, and the second transmission component are either belt drives or chain drives.

[0014] The beneficial effects of this invention are:

[0015] 1. Existing outdoor floodlighting devices typically use multiple individually driven lamps to illuminate the surrounding environment and individually control the illumination angle and position. However, the floodlighting device in this technology can achieve simultaneous adjustment of multiple vertical lamps to illuminate multiple directions through a single drive. This floodlighting device can fix and control the multi-directional illumination angle of the lamps, or it can achieve dynamic rotation of the lamps through timed forward and reverse rotation of the motor, so as to achieve dynamic illumination angle, reduce costs, and the floodlighting device can be applied to various locations.

[0016] 2. The lamp in this floodlight device is mounted on the second rotating component. The second rotating component is driven to rotate by the first rotating component, thereby changing the position of the lamp on the circumference. The angle adjustment component on the first rotating component changes the vertical angle of the lamp, thus changing the illumination of the surrounding environment. The angle adjustment component is connected to the first rotating component through a transmission component. This floodlight device has a novel structure, is stable and reliable, and is easy to adjust. Attached Figure Description

When the main transmission component 83 is activated, the first gear 82 rotates, and the second transmission component 13 drives the second gear to rotate. Simultaneously, the other angle adjustment components 8 are activated through the first transmission component 81.

[0031] Based on the above embodiments, both the lamp 9 and the top lamp 11 include a spherical shell. The spherical shell is connected to the cavity 101 via a movable shaft.

[0032] Based on the above embodiments, the main transmission component 83, the first transmission component 81, and the second transmission component 13 are belt drives or chain drives.

[0033] The above improvements are specifically as follows: Figures 1 to 4As shown: The projection device includes a base 1, on which a first housing 2 is mounted. Inside the first housing 2 are a drive component 3 and a support frame 4. A first rotating component 5 is movably connected to the center of the support frame 4. The bottom of the first rotating component 5 passes through the center of the support frame 4 and is connected to the drive component 3. The drive component 3 is a motor 31. The support frame 4 provides support for the first rotating component 5. The first rotating component 5 includes a rotating rod 51, on which multiple main gears 52 are mounted. The main gears 52 are evenly distributed on the rotating rod 51 and fixedly connected to it. The end of the rotating rod 51 is connected to the output shaft of the motor 31. When the motor 31 starts, the rotating rod 51 rotates, and the main gears 52 rotate synchronously. A second rotating component 6, meshing with the main gears 52, rotates synchronously. Multiple sets of lamps 9 are mounted on each of the second rotating components 6. These lamps 9 can rotate along the circumference of the second rotating component 6, illuminating the surrounding environment. The second rotating component 6 includes a driven gear 61 that meshes with the main gears 52. The main gears 52 are external gears. Gear 61 is an internal gear. The upper end face of the driven gear 61 is provided with an upper rail 611, and the lower end face is provided with a lower rail 612. The upper end face of the first housing 2 is provided with a connecting ball 12 corresponding to the lower rail 612. The connecting ball 12 can move along the lower rail 612. The connection ball 12 and the lower rail 612 prevent the first housing 2 from being rotated synchronously by the driven gear 61, and at the same time provide support for the driven gear 61. The driven gears 61 are connected to each other through a second housing 7. The upper end face of the second housing 7 is provided with a connecting ball 12, and the lower end face is provided with a support column 71. The connecting ball 12 on the upper end face of the second housing 7 is movably connected to the lower rail 612 of the previous driven gear 61, and the support column 71 on the lower end face of the second housing 7 is movably connected to the upper rail 611 of the next driven gear 61. The second housing 7 and the first housing 2 play the same role, preventing the driven gear 61 from driving the second housing 7 to rotate, while providing support for the driven gear 61 connected to the second housing 7.The second rotating component 6 also includes a cylindrical housing 62, which engages with the driven gear 61. The cylindrical housing 62 is hollow inside and has symmetrical openings 621 on its sides. A frame 622 extends inward from the sidewall of the opening 621, providing a place for the lamp 9. The rotation of the first rotating component 5 enables the rotation of the second rotating component 6, thereby changing the position of the lamp 9 and affecting its illumination range. The angle of the lamp 9 can be changed by the angle adjusting component 8, which is mounted on the first rotating component 5. The rotating rod 51 has a through groove 511 on its sidewall. The angle adjusting component 8 includes a vertical... A first gear 82 and a second gear are disposed at the through slot 511, spaced vertically apart. Both the first gear 82 and the second gear are connected to the through slot 511 via connecting shafts. One end of the connecting shaft of the first gear 82 is connected to one end of the connecting shaft of the second gear via a second transmission member 13. When the first gear 82 rotates, the second gear rotates synchronously via the second transmission member 13. One end of the connecting shaft of the first gear 82 connected to the second transmission member 13 extends and is connected to the adjacent first gear 82 via a first transmission member 81, so that the rotation of the first gear 82 can drive the rotation of the second gear and other gears. The rotation of the angle adjusting component 8 causes the first gear 82 to rotate, and through the other end of the connecting shaft, it is connected to the second bevel gear 54 fixed on the rotating rod 51 via the main transmission component 83. The second bevel gear 54 meshes with the first bevel gear 53, which is fixedly sleeved on the rotating rod 51. The rotation of the first bevel gear 53 drives the second bevel gear 54 to rotate, and the main transmission component 83 drives the rotation. The first gear 82 and the second gear are spaced apart to reasonably distribute the number of lamps 9. The lamps 9 can be equipped with individual power supplies or share a single power supply. The lamps 9 include a spherical shell, which is connected to the frame 622 via a movable shaft. The spherical shell has an opening 621, and an LED bead is installed at the opening 621. A third gear is installed around the spherical shell, which meshes with the first gear 82. The third gear meshes with the first gear 82 and the second gear. The transmission component is a belt drive or a chain drive. The rotation of the drive component 3 changes the circumferential position of the lamp 9. The angle of the lamp 9 is changed through the bevel gear and the transmission component. This lighting device has a novel structure, is stable and reliable, and is easy to adjust. It is suitable for any outdoor light show scene. The motor 31 can be programmed to achieve forward and reverse rotation of the motor 31, so as to achieve dynamic illumination of the lamp 9 and enhance the atmosphere.

[0034] The upper end of the rotating rod 51 is fixed with an extended arc plate 10. A cavity 101 is provided between the arc plates 10. The cavity 101 is used to place the top light 11. The third gear on the top light 11 meshes with the first gear 82 to realize the change of the upward illumination angle of the top light 11 or dynamic swing.

[0035] This second embodiment is basically the same as the first embodiment, except that: the angle adjustment components 8 are connected by a first transmission component 81. The angle adjustment component 8 includes multiple sets of first gears 82 vertically arranged in the through groove 511. The adjacent first gears 82 mesh with each other. The first gears 82 are all connected to the through groove 511 through a connecting shaft. The lamps 9 are all corresponding to the first gears 82. The rotation of the first gears 82 drives the lamps 9 to rotate. One end of the connecting shaft of the initial first gear 82 is connected to a main transmission component 83. The main transmission component 83 passes through the main gear 52 and is connected to the second bevel gear 54. When the main transmission component 83 is started, the initial first gear 82 rotates, the meshing first gears 82 rotate, and simultaneously drive the other angle adjustment components 8 to start through the first transmission component 81.

[0036] The above improvements are specifically as follows: Figure 5 As shown: Angle adjusting components 8 are installed in the through groove 511. Adjacent angle adjusting components 8 are connected via a first transmission component 81. Each angle adjusting component 8 includes multiple sets of first gears 82 vertically installed in the through groove 511. Adjacent first gears 82 mesh with each other. Each first gear 82 is connected to the through groove 511 via a connecting shaft. Each lamp 9 corresponds to a first gear 82. One end of the connecting shaft of the initial first gear 82 is connected to the initial first gear 82 of the other angle adjusting components 8 via the first transmission component 81. The other end of the connecting shaft of the initial first gear 82 is connected to a main transmission component 83, which passes through the main gear 52. A first bevel tooth is fitted onto the lower end of the rotating rod 51. Wheel 53, first bevel gear 53 meshes with second bevel gear 54, one end of second bevel gear 54 is connected to first gear 82 through main transmission component 83. The rotation of first bevel gear 53 drives second bevel gear 54 to rotate. The main transmission component 83 drives, first gear 82 rotates synchronously. The rotation of the meshing gears causes the lamp 9 to rotate. First gear 82 rotates forward, and adjacent meshing first gear 82 rotates in reverse. Multiple sets of gears rotate alternately, reducing the use of transmission components while increasing the number of lamps 9 and driving the lamps 9 to rotate. This enables the spherical shell to rotate in opposite directions, forming multiple lights that illuminate the surrounding environment, achieving projection from more angles and positions, and creating a visually appealing light show.
