Description

Technical Field

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

[0002] The double-rotating stacked floodlight is a floodlight with a rotatable stacked structure, which combines flexible adjustment and powerful lighting. It is suitable for a variety of scenarios. Simply put, the double-rotating stacked floodlight is a "multi-layered spotlight" that can flexibly adjust the angle. It is usually composed of multiple stacked lamp bodies, and adjacent lamp bodies and lamp bodies and base can rotate relative to each other.

[0003] Currently, common floodlights on the market have certain limitations in terms of adjusting the projection angle and position. Many traditional floodlights can only project light in a single direction or at a limited angle, which makes it difficult to meet the increasingly diverse lighting needs. For example, in large exhibition spaces and complex stage performance venues, it is necessary to be able to flexibly adjust the projection direction and position to highlight the features of exhibits or create rich and varied lighting effects.

[0004] Some adjustable floodlights suffer from inadequate structural design, resulting in complex and unstable adjustment processes. Issues such as component loosening and angle shifts during adjustment can negatively impact lighting performance and equipment lifespan. Furthermore, existing floodlight drive mechanisms may lack convenience and efficiency, hindering rapid and precise adjustment of the projection angle and position. Therefore, to address these problems, a dual-rotation stacked floodlight device is proposed to meet the demands of complex and varied lighting scenarios and improve the performance and stability of the floodlight. Utility Model Content

[0005] The purpose of this invention is to solve the problems that traditional floodlights in the prior art can only project light in a single direction or at a limited angle, which makes it difficult to meet the increasingly diverse lighting needs. Furthermore, problems such as loose parts and angle deviations are prone to occur during the adjustment process, affecting the projection effect and the service life of the equipment. Therefore, a double-rotation stacked floodlight is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A double-rotated stacked floodlight includes a lamp holder, on which a first floodlight and a second floodlight are rotatably connected. The first floodlight is connected to the lamp holder via a short shaft, and its angle can be adjusted on the lamp holder via the short shaft. Arc-shaped racks are slidably connected to both sides of the lamp holder, and the second floodlight is rotatably connected to the arc-shaped rack via the short shaft. The second floodlight's angle can be adjusted on the arc-shaped rack via the short shaft, and its position and direction can be adjusted by sliding on the lamp holder via the arc-shaped rack.

[0008] Preferably, a limiting groove is provided on the inner side of the arc-shaped rack, and limiting strips are provided on both sides of the lamp holder to match the limiting groove. Both the limiting groove and the limiting strip are arc-shaped structures, and the center of the arc of the limiting groove, the limiting strip and the arc-shaped rack coincide.

[0009] Preferably, the lamp holder is provided with a bearing seat, a connecting shaft is inserted into the bearing seat, and gears are provided at both ends of the connecting shaft. The gears mesh with an arc-shaped rack. One end of one of the gears is connected to a first track wheel. The lamp holder is also equipped with a driver. The driving end of the driver is connected to a second track wheel. A track is sleeved between the first track wheel and the second track wheel.

[0010] Preferably, the lamp holder has a built-in cavity, and its driver is installed inside the cavity. The driving end of the driver extends through the side wall of the cavity to the outside. A protective cover is connected to the outside of the lamp holder by screws, and the protective cover covers the first track wheel, the second track wheel and the track.

[0011] Preferably, a second motor is mounted on the outer side of one of the arc-shaped racks, and the drive end of the second motor is connected to the short shaft on one side of the second floodlight. The second floodlight is driven by the second motor to adjust the angle of the arc-shaped rack.

[0012] Preferably, the front surface of the lamp holder is integrally provided with a connecting ear, the connecting ear is a triangular structure and protrudes from the front surface of the lamp holder, and the first floodlight is rotatably connected to the connecting ear through a short shaft.

[0013] Preferably, a first motor is mounted on the outer side of one of the connecting ears, and the driving end of the first motor is connected to the short shaft on one side of the first floodlight.

[0014] Preferably, the lower surface of the lamp holder is equipped with a rotating seat, and the lower surface of the rotating seat is provided with multiple fixing feet at equal intervals in a circular pattern, with screw holes provided on the fixing feet.

[0015] Compared with the prior art, this utility model provides a double-rotation stacked light projection, which has the following beneficial effects:

[0016] 1. This double-rotated stacked projector allows the first projector to be angled via its short axis on the lamp holder, while the second projector can not only be angled via its short axis on the arc-shaped rack, but also adjust its position and direction by sliding the arc-shaped rack on the lamp holder. This design makes the adjustment of the projection angle and position more diverse, meeting the complex projection needs in different scenarios. For example, in stage lighting setup, it can more accurately illuminate specific areas or create special light and shadow effects.

[0017] 2. This double-indexed stacked projector features a limiting groove on the inner side of the arc-shaped rack that matches the limiting strip on the side of the lamp holder. Both grooves are arc-shaped and coincide with the arc center of the rack. This ensures the stability and precision of the arc-shaped rack as it slides on the lamp holder, preventing wobbling or offset and guaranteeing the reliability of the second floodlight position adjustment. This improves the accuracy and stability of the projection and maintains good working condition even during long-term use. Furthermore, the gears at both ends of the shaft mesh with the arc-shaped rack, and the driver drives the first track wheel via the track, which in turn drives the gears, enabling convenient driving of the arc-shaped rack. This makes adjusting the position of the second floodlight easier and more convenient to operate. Moreover, the driver is installed inside the lamp holder's built-in cavity, and a protective cover covers the first track wheel, the second track wheel, and the track, protecting the drive components, extending their service life, and improving the safety and aesthetics of the equipment.

[0018] 3. This double-rotating stacked projector is equipped with a first motor driving the first projector and a second motor driving the second projector, which adjust the angle on their respective short axes. This allows for independent control of the angles of the two projectors, further enhancing the flexibility and precision of the projection angle adjustment. It facilitates personalized lighting projection settings according to actual needs. Furthermore, the lower surface of the lamp holder is equipped with a rotating base, and the lower surface of the rotating base has multiple fixing feet with screw holes at equal intervals on the circumference. This makes it easy to install and fix the entire device in different positions. The rotating base can also realize the overall rotation adjustment of the device, increasing its convenience and adaptability.

[0019] The parts not covered in this device are the same as or can be implemented using existing technologies. This utility model proposes a double-rotation stacked projection device that can flexibly adjust the position and angle in multiple dimensions to meet the complex and varied lighting needs in different scenarios and improve the diversity and accuracy of lighting effects.

[0028] See Figure 1-2This is a structural diagram of the double-rotation stacked floodlight in this embodiment. The double-rotation stacked floodlight includes a lamp holder 100, on which a first floodlight 104 and a second floodlight 106 are rotatably connected. A rotating seat 102 is mounted on the lower surface of the lamp holder 100, and the lower surface of the rotating seat 102 is provided with multiple fixing feet equidistantly arranged in a circular pattern. The fixing feet are provided with screw holes. This design facilitates the fixing of the entire device to various mounting surfaces with screws. Furthermore, the rotating seat 102 can also allow the lamp holder 100 to rotate at a certain angle in the horizontal direction, such as ±360°, further increasing the flexibility and adaptability of the floodlight. Specifically, a connecting ear 101 is integrally provided on the front surface of the lamp holder 100. The connecting ear 101 is a triangular structure and protrudes from the front surface of the lamp holder 100. The first floodlight 104 is rotatably connected via a short shaft. On the connecting ear 101, a first motor 1041 is mounted on the outer side of one of the connecting ears 101, and the driving end of the first motor 1041 is connected to the short shaft on one side of the first floodlight 104. Driven by the first motor 1041, the first floodlight 104 can be angled on the lamp holder 100 with the short shaft as the axis. The adjustment range can be achieved by controlling the rotation angle of the first motor 1041 according to actual needs to meet the projection needs in different directions. Both sides of the lamp holder 100 are slidably connected to the arc-shaped rack 105, and the second floodlight 106 is rotatably connected to the arc-shaped rack 105 through the short shaft. The second floodlight 106 can be angled on the arc-shaped rack 105 through the short shaft, and the position and direction of the second floodlight 106 can be adjusted by the arc-shaped rack 105 sliding on the lamp holder 100. Specifically, in Figure 5 In the lamp holder 100, a limiting groove 1051 is provided on the inner side of the arc-shaped rack 105, and limiting strips 108 are provided on both sides of the lamp holder 100 to match the limiting groove 1051. The limiting groove 1051 and the limiting strip 108 are both arc-shaped structures, and the center of the arc of the limiting groove 1051, the limiting strip 108 and the arc of the arc-shaped rack 105 coincide. This limiting structure can ensure that the arc-shaped rack 105 slides smoothly on the lamp holder 100 and always stays on the predetermined arc trajectory.

[0029] See Figure 3-4This is a structural diagram of the angle adjustment component of the second floodlight in this embodiment. In this embodiment, a bearing seat 107 is provided on the lamp holder 100. A connecting shaft is inserted into the bearing seat 107, and gears 1071 are provided at both ends of the connecting shaft. The gears 1071 mesh with the arc-shaped rack 105. One end of one of the gears 1071 is connected to a first track wheel 1072. The lamp holder 100 is also equipped with a driver. The driving end of the driver is connected to a second track wheel 1073. A track 1074 is sleeved between the first track wheel 1072 and the second track wheel 1073. The lamp holder 100 has a built-in cavity, and its driver is installed in the cavity. The driving end of the driver extends through the side wall of the cavity to the outside. A protective cover 103 is connected to the outside of the lamp holder 100 by screws, and the protective cover 103 covers the first track wheel 1072, the second track wheel 1073 and the track 1074. When the driver starts, it drives the second track wheel 1073 to rotate, which in turn drives the first track wheel 1072 to rotate via the track 1074. This, in turn, drives the gear 1071 connected to it to rotate. Since the gear 1071 meshes with the arc-shaped rack 105, the arc-shaped rack 105 slides in an arc along the guide of the limiting strip 108 and the limiting groove 1051 on both sides of the lamp holder 100, thereby realizing the adjustment of the position and direction of the second floodlight 106. Furthermore, a second motor 1061 is installed on the outer side of one of the arc-shaped racks 105, and the drive end of the second motor 1061 is connected to the short shaft on one side of the second floodlight 106. The second floodlight 106 is driven by the second motor 1061 to adjust the angle of the arc-shaped rack 105. By controlling the rotation of the second motor 1061, the angle of the second floodlight 106 on the arc-shaped rack 105 can be finely adjusted, further enriching the projection angle range of the second floodlight 106.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
