Description

Technical Field

[0001] This utility model relates to the field of architectural lighting, and in particular to a building facade lighting device. Background Technology

[0002] Building facade lighting design is one of the main forms of urban nighttime lighting. Nighttime building lighting emphasizes an eye-catching visual effect, completely different from daytime sunlight. Sometimes, in order to achieve this eye-catching visual effect, some designers adopt the concept of "the brighter the better." However, this unreasonable nighttime lighting will generate a lot of energy consumption and light pollution, so we must give more thought and research to the power consumption and safety aspects of building facade lighting.

[0003] Chinese utility model patent (publication number: CN220567108) discloses a building facade lighting device, including a slide rail. A slider is slidably connected to the surface of the slide rail. An electric telescopic rod is bolted to the four corners of the top of the slider. A housing is bolted to the top of the electric telescopic rod. A rotating plate is rotatably connected to the center of the housing cavity via a bearing. A slot is formed at the bottom of the rotating plate. An installation groove is formed at the lower part of the housing cavity. An adjustment mechanism is provided inside the installation groove. An annular shell is bolted to the top of the rotating plate. Limiting plates are bolted to both sides of the annular shell cavity. When the lighting module is damaged and needs to be replaced, the handles on both sides of the annular shell are pulled. This pulls the pull plate and the insertion rod out of the locking groove. At this time, the connecting block loses its limiting and fixing function, allowing the lighting module to be removed. After removing the lighting module, a new lighting module is replaced. The positioning rod at the bottom of the lighting module is inserted into the positioning ring for positioning. Then, the handles on both sides are released, causing the second spring to push the pull plate inward until the insertion rod is inserted into the locking groove, completing the replacement.

[0004] However, when the connecting block is released from its restraint and fixation by pulling the handles on both sides of the annular shell, there is no extra hand to remove the lighting module, which is inconvenient. Therefore, a building facade lighting device is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Please refer to Figure 1 A building facade lighting device includes a mounting plate 1. Fixing holes 20 are provided at each of the four corners of the mounting plate 1. The device can be installed by passing expansion bolts or similar bolts through the fixing holes 20 and then fixing it to the building facade. A bottom housing 2 is fixedly mounted on the upper surface of the mounting plate 1. A connecting plate 3 is rotatably mounted on the top of the bottom housing 2. The top of the bottom housing 2 has an open structure design, and a rotating shaft is rotatably mounted inside the bottom housing 2. The rotating shaft passes through the bottom of the connecting plate 3 and is fixedly connected to the connecting plate 3. An angle adjustment assembly is installed between the bottom housing 2 and the connecting plate 3. The angle adjustment assembly includes a motor 10, a worm gear 11, and a semi-circular worm wheel 12. The motor 10 is fixedly installed inside the bottom housing 2, and the worm gear 11 is fixedly installed at the output end of the motor 10. The semi-circular worm wheel 12 is fixedly installed at the bottom of the connecting plate 3. The other end of the semi-circular worm wheel 12 is rotatably connected to the bottom housing 2. The worm gear 11 and the semi-circular worm wheel 12 are connected by a transmission. The motor 10 drives the worm gear 11 to rotate, and the worm gear 11 drives the semi-circular worm wheel 12 to rotate, thereby adjusting the orientation of the connecting plate 3.

[0031] Reference Figure 1-3 A mounting housing 4 is fixedly installed on the top of the connecting plate 3. A mounting groove 5 is formed on the upper surface of the mounting housing 4. A connecting post 6 is inserted into the mounting groove 5, and the diameter of the connecting post 6 matches the diameter of the mounting groove 5. The lighting body 7 is fixedly installed on the top of the connecting post 6. L-shaped clips 8 are slidably installed on both inner walls of the mounting groove 5. Slots 9 are formed on both sides of the connecting post 6. A drive assembly is installed inside the mounting housing 4, which contains a mounting chamber. The drive assembly is installed inside the mounting chamber, and holes are formed on both inner walls of the mounting groove 5. The top of the L-shaped clip 8 slides through the holes. The L-shaped clip 8 is mounted on the drive assembly. The drive assembly moves the L-shaped clip 8, connecting and separating it from the slots 9 on the connecting post 6. This allows for quick assembly and disassembly of the lighting body 7, and the entire operation can be completed with one hand, making it quite convenient. A guide rod 16 is fixedly installed inside the housing 4. A through hole 17 is provided on the L-shaped clip 8. The guide rod 16 passes through the inside of the through hole 17. The guide rod 16 plays a good guiding role in the movement of the L-shaped clip 8, thereby facilitating the connection between the L-shaped clip 8 and the slot 9.

[0032] Reference Figure 1 , Figure 2 and Figure 4 The drive assembly includes a bidirectional screw 13 rotatably mounted inside the mounting housing 4 and threaded sleeves 14 threaded onto the surfaces of both ends of the bidirectional screw 13. The bottom of the L-shaped retainer 8 is fixedly connected to the threaded sleeves 14. By rotating the bidirectional screw 13, the two threaded sleeves 14 move closer or further apart, thereby achieving the connection and separation between the L-shaped retainer 8 and the retaining groove 9. A knob 15 is fixedly mounted on one end of the bidirectional screw 13 extending into the mounting housing 4. The knob 15 facilitates the rotation of the bidirectional screw 13.

[0033] Reference Figure 1 , Figure 2 and Figure 4 Positioning posts 18 are fixedly installed on the bottom of both sides of the main body 7 of the lighting lamp. Positioning sleeves 19 are fixedly installed on both sides of the mounting housing 4 located in the mounting groove 5. Positioning posts 18 are inserted into the inside of positioning sleeves 19. With the setting of positioning sleeves 19 and positioning posts 18, when the connecting post 6 is inserted into the mounting groove 5, it is convenient to make the slot 9 align with the L-shaped clip 8.

[0034] The implementation principle of this utility model is as follows:

[0035] In use, the device can be installed by passing expansion bolts through the fixing holes 20 and fixing it to the building facade. When it is necessary to adjust the angle of the lighting body 7, the motor 10 is started. The motor 10 drives the worm gear 11 to rotate, and the worm gear 11 drives the semi-circular worm wheel 12 to rotate, thereby adjusting the orientation of the lighting body 7. Moreover, since the worm gear 11 and the semi-circular worm wheel 12 have a self-locking function, the orientation angle of the lighting body 7 is not easily changed by external forces.

[0036] When the main body 7 of the lighting lamp needs to be replaced, the double-ended screw 13 is rotated by the knob 15, so that the two screw sleeves 14 on the surface of the double-ended screw 13 move away from each other, thereby moving the top of the L-shaped clip 8 out of the slot 9, and the main body 7 of the lighting lamp and the connecting post 6 can be taken out from the inside of the mounting slot 5. When the new main body 7 of the lighting lamp is placed in the mounting slot 5, the positioning post 18 at the bottom of the main body 7 is inserted into the positioning sleeve 19 on the upper surface of the mounting housing 4. Then, the double-ended screw 13 is rotated in the opposite direction, so that the top of the L-shaped clip 8 is inserted into the slot 9.

[0037] In summary, this device, through the setting of the angle adjustment component, can conveniently adjust the orientation angle of the lighting body 7. Moreover, the self-locking mechanism of the worm gear 11 and the semi-circular worm wheel 12 in the angle adjustment component makes the orientation angle of the lighting body 7 more stable. By driving the L-shaped clip 8 to move through the drive component, the L-shaped clip 8 can be connected and separated from the slot 9 on the connecting column 6, thereby enabling quick assembly and disassembly of the lighting body 7. The entire operation can be completed with one hand, which is quite convenient.
