Description

Technical Field

[0001] The utility model relates to the technical field of projection lamps, in particular to a rotating projection lamp for lighting engineering. Background Art

[0002] Lighting engineering refers to the use of artificial light sources and optical devices, in accordance with certain design principles and methods, to provide appropriate lighting effects and visual environment for specific places or purposes. As a type of lamp involved in lighting engineering, projection lamps can project light emitted by light sources into preset patterns or colors for decoration, identification or indication.

[0003] A narrow-beam LED projection lamp with easy angle adjustment, publication number CN219199080U, includes a projection lamp body, a support frame, and a base. Connecting plates are fixedly arranged on both sides of the projection lamp body. The support frame is "U"-shaped. The two sides of the support frame are rotatably connected to the connecting plates by rotating screws. A bearing hole is opened in the middle of the bottom of the support frame, and a bearing is arranged in the bearing hole. The inner circle of the bearing is fixedly connected to the support shaft and extends to the base and is fixedly connected to the base. Support blocks are fixedly arranged on the base around the support shaft.

[0004] Although the utility model can make the projection lamp body rotate and project in all directions by providing a rotating screw and a bearing, making the projection lamp more widely used and applied in more fields, during actual use, the projection lamp body can rotate 360° on the same vertical plane under the action of the rotating screw. After adjusting the angle, the vertical plane of the projection lamp body is fixed by aligning the limit rod on the support frame with the adjustment hole on the connecting plate and inserting it. Since the projection lamp body needs to be operated by the staff during the angle adjustment process, the workload of the staff will increase. In addition, when the height of the projection lamp body exceeds the height of the staff, the staff needs to climb to adjust the angle of the projection lamp body, which causes inconvenience in use. In view of this, we propose a rotating projection lamp for lighting engineering. Utility Model Content

[0034] Furthermore, through the cooperation of the pattern piece and the lens 41, the light emitted by the light source in the projection lamp body 4 can be projected into a preset pattern, thereby increasing the aesthetics of the lighting effect;

[0035] A lamp holder 3 for mounting the projection lamp body 4 is provided between the connecting rod 2 and the projection lamp body 4. The lamp holder 3 is U-shaped and has an opening facing downward. The opening end of the lamp holder 3 is rotatably connected to the connecting rod 2 via a positioning shaft 22. A driving component for driving the positioning shaft 22 to rotate is provided on one side of the connecting rod 2.

[0036] The driving assembly includes two mutually meshing gears 6 and a second servo motor 7, a positioning shaft 22 corresponds to the center of one of the gears 6, one end of the positioning shaft 22 passes through the lamp holder 3 and the corresponding gear 6 in sequence and is fixedly connected to the corresponding gear 6, the other gear 6 is rotatably connected to the connecting rod 2 through a rotating shaft, and a mounting plate 21 in an L shape for mounting the second servo motor 7 is provided on the side wall of the connecting rod 2 and below the gear 6;

[0037] Furthermore, one end of the rotating shaft away from the connecting rod 2 passes through the corresponding gear 6 and is coaxially connected to the output shaft of the second servo motor 7. The rotating shaft is fixedly connected to the corresponding gear 6. As is well known to those skilled in the art, the second servo motor 7 drives the rotating shaft to rotate after power is supplied, and then drives the positioning shaft 22 to rotate through the cooperation of two mutually meshing gears 6, thereby causing the lamp holder 3 to swing to adjust the angle of the projection lamp body 4.

[0038] As a preferred embodiment of the present invention, a column 1 is provided below the connecting rod 2, a cylindrical groove slidably connected to the connecting rod 2 is provided at the top of the column 1, a threaded rod 12 threadedly connected to the connecting rod 2 is rotatably connected at the center of the cylindrical groove, and a first servo motor 13 is embedded at the center of the column 1 and below the threaded rod 12;

[0039] Furthermore, a storage groove for accommodating the first servo motor 13 is opened at the center of the column 1 and near the bottom end, and the bottom end of the threaded rod 12 is coaxially connected to the output shaft of the first servo motor 13. As is well known to those skilled in the art, the first servo motor 13 drives the threaded rod 12 to rotate after power is supplied.

[0040] As a preferred embodiment of the present invention, a base plate 5 is provided at the bottom of the column 1, and an anti-slip gasket is embedded at the bottom of the base plate 5 to increase the friction between the base plate 5 and the ground. The base plate 5 is fixedly connected to the ground by anchor bolts to fix the position of the base plate 5.

[0041] As a preferred embodiment of the present invention, the bottom end of the column 1 is rotatably connected to the base plate 5 so that the angle between the column 1 and the base plate 5 can be relatively adjusted. A fixing block 11 is provided on the side wall of the column 1 near the bottom end. A bolt 111 is threadedly connected to the top of the fixing block 11. The screw end of the bolt 111 passes through the corresponding fixing block 11 and contacts the top of the base plate 5 so as to fix the position of the fixing block 11 and prevent the column 1 from rotating autonomously without manual operation and affecting its stability.

[0042] When the rotating projection lamp of the lighting project of the utility model is used, the bottom plate 5 is fixed to the ground by the anchor bolts, and then the angle of the column 1 is adjusted as needed. First, the bolt 111 is loosened so that the end of the screw does not contact the top of the bottom plate 5, and then the column 1 is rotated so that the fixing block 11 swings accordingly to achieve angle adjustment, and then the bolt 111 is tightened so that the end of the screw contacts the top of the bottom plate 5 to fix the position of the fixing block 11;

[0043] Then, the angles of the lamp holder 3 and the projection lamp body 4 are adjusted according to the use requirements, and the second servo motor 7 is connected and started to drive the rotating shaft and the corresponding gear 6 to rotate. At the same time, another gear 6 drives the positioning shaft 22 to rotate, so that the lamp holder 3 drives the projection lamp body 4 to swing with the positioning shaft 22 as the center point, thereby realizing the angle adjustment of the projection lamp body 4;

[0044] When the pattern piece needs to be replaced, first connect and start the first servo motor 13 to drive the threaded rod 12 to rotate. At the same time, the connecting rod 2 threadedly connected to the threaded rod 12 moves in the cylindrical groove along the axial direction of the threaded rod 12, thereby adjusting the height of the top end of the connecting rod 2. When the distance between the top end of the connecting rod 2 and the bottom end of the column 1 is adjusted to the minimum, the limit ring 42 is separated from the projection lamp body 4, and then the pattern piece on the top of the lens 41 is replaced, and then the limit ring 42 is installed with the projection lamp body 4, and then the height of the projection lamp body 4 is adjusted according to the needs of use.
