Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to an adjustable lighting device. Background Technology

[0002] A lighting fixture is a device used to provide illumination, widely used in homes, offices, shops, and other places requiring artificial light. Its basic function is to emit light through a light source module to meet the brightness requirements of different environments. Traditional lighting fixtures typically employ a fixed design, meaning that once installed and set up, the position of the light source remains unchanged. While this fixed setting provides basic lighting functionality, it often lacks the flexibility to adjust it during actual use.

[0003] Patent CN211083928U discloses an angle-adjustable nighttime lighting device for green construction. This device includes a carrier and a generator, with the generator fixedly mounted on the upper surface of the carrier. This invention receives remote control signals via an external signal receiver controller and remotely controls the electric lifting rod, motor one, and motor two according to the received commands. This allows for remote control of the lighting height, direction, and angle, making it more convenient and labor-saving to use. Furthermore, by receiving signals through a stepless dimming driver, the brightness of the lighting can be adjusted, enabling the device to illuminate various environments and further enhancing its usability.

[0004] While the existing technology can adjust the height and tilt angle of the lighting fixture during practical use, it lacks a horizontal adjustment structure. When the horizontal position of the lighting fixture needs to be adjusted, the operator needs to rotate the carrier, which requires the addition of a bracket. This makes it very inconvenient to adjust the horizontal position of the lighting fixture. Therefore, we propose an adjustable lighting fixture. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable lighting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable lighting fixture includes a base.

A horizontal component is located at the top of the electric lifting rod. The horizontal component includes a first housing fixedly connected to the movable end of the electric lifting rod. A first worm gear is rotatably connected between the upper and lower sides of the inner wall of the first housing. A first power component is located inside the first housing to drive the first worm gear to rotate. The top of the first worm gear shaft passes through the top of the inner wall of the first housing and is coaxially connected to a rotating disk. A pitch component is located at the center of the top of the rotating disk. The first power component drives the first worm gear to rotate, which in turn drives the rotating disk to rotate, which in turn drives the pitch component to rotate, thus achieving adjustment of the horizontal position of the lighting fixture without rotating the entire device.

[0008] The pitch component includes a second housing fixedly connected to the top of the rotating disk. A second worm gear is rotatably connected between the left and right sides of the inner wall of the second housing.

The front end of the first worm gear shaft is rotatably connected to the front side of the inner wall of the first housing to improve the stability of the first worm gear.

[0012] Preferably, the top of the rotating disk is provided with two fixed upright plates arranged symmetrically from left to right, and the two ends of the second worm gear shaft are respectively rotatably connected to the opposite sides of the two fixed upright plates to improve the stability of the second worm gear.

[0013] Preferably, the second power component includes a second servo motor installed on the rear side of the inner wall of the second housing. The output shaft of the second servo motor is coaxially connected to a second worm gear that meshes with and drives the second worm wheel. The second servo motor drives the second worm gear to rotate, thereby causing the second worm gear to rotate. The front end of the second worm gear shaft is rotatably connected to the front side of the inner wall of the second housing to improve the stability of the second worm gear.

[0014] Preferably, the connecting frame includes two connecting rods arranged symmetrically on the left and right, the bottom ends of the two connecting rods are fixedly connected to the outer wall of the second worm gear shaft, and a mounting plate is provided between the two connecting rods. The lighting lamp is detachably connected to the front side of the mounting plate by bolts.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This adjustable lighting device, through a first power component designed within the first housing, drives the first worm gear and the rotating disk to rotate, thereby achieving independent adjustment of the lighting in the horizontal direction. Compared with existing technologies, this design does not require rotating the entire device to easily change the horizontal direction of the light, greatly improving the ease of use of the device.

[0017] 2. This adjustable illuminator drives the second worm gear and connecting bracket to rotate through the second power component inside the second housing, thereby easily adjusting the pitch angle of the illuminator.

[0027] Please see Figures 1-5 This utility model provides a technical solution:

[0028] An adjustable lighting device includes a base 1. An electric lifting rod 2 is provided at the center of the top of the base 1 to drive a horizontal component 3 to move up and down, thereby adjusting the height of the lighting lamp 6.

[0029] The pitch component 4 includes a second housing 40 fixedly connected to the top of the rotating disk 32.

[0030] In this embodiment, the top of the base 1 is provided with two circular fixing tubes 10 arranged symmetrically from left to right, and the bottom of the first housing 30 is provided with two positioning vertical rods 36 arranged symmetrically from left to right. The two positioning vertical rods 36 are slidably connected to the two circular fixing tubes 10 respectively, which improves the stability of the first housing 30 and also effectively prevents the moving rod of the electric lifting rod 2 from bending.

[0031] Specifically, a rectangular upright plate 11 is provided on the top of the base 1 and near the rear side. A controller 7 is provided on the top of the rear side of the rectangular upright plate 11.

[0032] Furthermore, the first power component includes a first servo motor 34 installed on the rear side of the inner wall of the first housing 30. The output shaft of the first servo motor 34 is coaxially connected to a first worm 35 that meshes with the first worm gear 31.

[0034] Furthermore, the second power component includes a second servo motor 42 installed on the rear side of the inner wall of the second housing 40. The output shaft of the second servo motor 42 is coaxially connected to a second worm 43 that meshes with the second worm gear 41.

[0035] Furthermore, the connecting frame 5 includes two connecting rods 50 arranged symmetrically on the left and right.

The power connection of the device should be reliable to ensure that the electric lifting rod 2, servo motor and lighting lamp 6 receive a continuous power supply. The electric lifting rod 2 is started using the controller 7 to adjust the height of the lighting lamp 6. By controlling the lifting of the lifting rod, the user can set the appropriate height of the lamp according to specific lighting needs, which is suitable for different room layouts or working environments. The first servo motor 34 located in the first housing 30 is started. This motor drives the first worm gear (35) to drive the first worm wheel 31 to rotate, thereby driving the rotating disk 32 to rotate, realizing the adjustment of the horizontal position of the lighting lamp 6. With base 1, the horizontal direction of the light can be easily changed to adapt to different lighting occasions. Then, the second servo motor 42 is started, which drives the second worm (43) to drive the second worm wheel 41 to rotate. The second worm wheel 41 drives the connecting frame 5 to rotate up and down, adjusting the pitch angle of the lighting lamp 6. The positioning vertical rod 36 on the top of base 1 cooperates with the circular fixed tube 10 to ensure the stability of the entire device. During the adjustment process, the device should maintain its inherent shape and stability to prevent structural distortion caused by movement. The controller 7 is used to control all adjustment components in all directions. Users can quickly and flexibly adjust the position of the lighting in various lighting situations to meet different usage needs, while ensuring the stability and durability of the device in long-term use.
