Description

An LED floodlight control device Technical Field

[0001] This utility model relates to the field of LED floodlight technology, and in particular to an LED floodlight control device. Background Technology

[0002] With the continuous development of lighting technology, LED floodlights have been widely used in many fields such as outdoor landscape lighting, architectural lighting, and sports stadium lighting due to their significant advantages such as high efficiency, energy saving, long lifespan, and high brightness. In practical applications, the illumination angle of the floodlight is one of the key factors affecting the lighting effect. Precise and flexible angle control can significantly improve the uniformity, coverage, and targeting of the lighting, thereby meeting the diverse lighting needs in different scenarios.

[0003] Currently, the two main methods for controlling the angle of LED floodlights on the market are manual adjustment and electric adjustment. Manual adjustment typically involves using mechanical structures, such as bolts or clips, to manually adjust the floodlight's angle. This method is extremely cumbersome, consuming significant manpower and time, and making it difficult to achieve precise angle adjustments. This inefficiency is particularly pronounced when frequent angle adjustments are required or during large-scale lighting system installation and commissioning.

[0004] Electric adjustment relies on a motor to drive the floodlight and adjust its angle. However, with existing electric adjustment devices, when the floodlight is heavy or needs to overcome significant resistance, the motor often struggles to provide sufficient power to achieve stable and precise angle control. This can lead to problems such as incomplete angle adjustment and vibration, affecting the lighting effect. Summary of the Invention

[0005] The technical problem to be solved by this utility model is that existing LED floodlights cannot meet the requirements of modern lighting for efficient, precise and reliable angle control. Therefore, we propose an LED floodlight control device.

[0006] To achieve the above objectives, this application adopts the following technical solution: an LED floodlight control device, comprising an LED module, a fixed frame surrounding the LED module, connecting plates fixedly connected to both sides of the fixed frame, a support frame on one side of the connecting plate, a rotating roller between the support frame and the connecting plate, the connecting plate and the support frame being rotatably connected via the rotating roller, a control component at one end of the rotating roller, the control component including a servo motor, a drive roller fixedly connected to the output end of the servo motor, a drive gear fixedly connected to the end of the drive roller away from the servo motor, a fixed cylinder sleeved on the surface of the drive roller, a rotating cylinder sleeved on the surface of the fixed cylinder, multiple connecting gears between the rotating cylinder and the drive gear, a toothed groove formed on the inner wall of the rotating cylinder, the drive gear meshing with the connecting gears, the connecting gears meshing with the rotating cylinder via the toothed grooves, the diameter ratio of the drive gear to the rotating cylinder being 1:3, a connecting plate fixedly connected to the end of the rotating cylinder away from the servo motor, a connecting rod fixedly connected to the side of the connecting plate away from the rotating cylinder, and a fixed connection between the end of the connecting rod away from the connecting plate and the rotating roller.

[0007] Preferably, a heat sink is mounted on the back of the LED module.

[0008] Preferably, a fixing seat is fitted onto the surface of the servo motor, and the end of the fixing seat away from the servo motor is fixedly connected to the support frame.

[0009] Preferably, the fixed cylinder is rotatably connected to the drive roller, and one side of the fixed cylinder is fixedly connected to the fixed seat.

[0010] Preferably, a plurality of evenly distributed balls are installed around the fixed cylinder, and the side of the balls away from the fixed cylinder contacts the inner wall of the rotating cylinder.

[0011] Preferably, a rotating rod is sleeved in the middle of the connecting gear, and a positioning cylinder is sleeved at the end of the rotating rod away from the connecting gear.

[0012] Preferably, the end of the positioning cylinder away from the rotating rod is fixedly connected to the bottom of the inner cavity of the fixed cylinder, and the rotating rod is rotatably connected to the inner wall of the positioning cylinder.

[0013] Preferably, the plurality of connecting gears are evenly distributed around the axis of the driving gear.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This utility model's LED floodlight control device aims to solve the existing LED floodlight angle control problem, achieving efficient, precise, and reliable angle adjustment. Its core consists of an LED module, a fixed frame, a connecting plate, a heat sink, a support frame, a rotating roller, and control components.

[0016] Its control components use a servo motor as the power source, which drives the drive gear to rotate. The drive gear meshes with multiple connecting gears, which in turn engage with the toothed grooves on the inner wall of the rotating drum to transmit power to the drum. Uniquely, the ratio of the drive gear to the diameter of the rotating drum is 1:3. This planetary gear structure excels in increasing motor torque, ensuring stable rotation when driving heavier structures such as LED modules and heat sinks.

[0017] The rotating drum drives the rotating rollers via a connecting disc and connecting rod, which in turn causes the connecting plate and LED module to rotate, thus controlling the angle of the floodlight. This structural design enables precise transmission ratio control, allowing for accurate adjustment of the LED module's rotation angle, meeting the requirements of modern lighting for precise angle control.

[0018] With its precise angle control and excellent stability and reliability, this device can be widely used in various lighting scenarios such as large venues and outdoor billboards, adapting to the needs of light angle adjustment in different environments, and has significant practical value and market prospects.

[0026] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] Referring to Figures 1 to 5, this utility model provides an LED floodlight control device, including an LED module 1. A fixing frame 101 is sleeved around the LED module 1. Connecting plates 102 are fixedly connected to both sides of the fixing frame 101. A heat sink 103 is installed on the back of the LED module 1. A support frame 2 is provided on one side of the connecting plate 102. A rotating roller 201 is provided between the support frame 2 and the connecting plate 102. The connecting plate 102 and the support frame 2 are rotatably connected by the rotating roller 201. A control device is provided at one end of the rotating roller 201. Component 3, the control component 3 includes a servo motor 301, a fixed seat 302 is sleeved on the surface of the servo motor 301, the end of the fixed seat 302 away from the servo motor 301 is fixedly connected to the support frame 2, a drive roller 303 is fixedly connected to the output end of the servo motor 301, and a drive gear 304 is fixedly connected to the end of the drive roller 303 away from the servo motor 301. After the servo motor 301 is started, the drive roller 303 at its output end starts to rotate, thereby driving the drive gear 304 fixedly connected to the drive roller 303 to rotate.

[0028] Furthermore, a fixed cylinder 305 is sleeved on the surface of the drive roller 303. The fixed cylinder 305 is rotatably connected to the drive roller 303. One side of the fixed cylinder 305 is fixedly connected to the fixed seat 302. A rotating cylinder 306 is sleeved on the surface of the fixed cylinder 305. Multiple evenly distributed balls 307 are installed around the fixed cylinder 305. The side of the balls 307 away from the fixed cylinder 305 contacts the inner wall of the rotating cylinder 306. Multiple connecting gears 308 are provided between the rotating cylinder 306 and the drive gear 304. The inner wall of the rotating cylinder 306 is provided with tooth grooves 311. The drive gear 304 meshes with the connecting gears 308. The connecting gears 308 mesh with the rotating cylinder 306 through the tooth grooves 311. The drive gear 304 meshes with the multiple connecting gears 308. Due to the rotation of the drive gear 304, power is transmitted to the connecting gears 308, causing the connecting gears 308 to rotate around their own rotating rods 309.

[0029] Furthermore, the diameter ratio of the driving gear 304 to the rotating drum 306 is 1:3. A rotating rod 309 is sleeved in the middle of the connecting gear 308. A positioning cylinder 310 is sleeved at the end of the rotating rod 309 away from the connecting gear 308. The end of the positioning cylinder 310 away from the rotating rod 309 is fixedly connected to the bottom of the inner cavity of the fixed cylinder 305. The rotating rod 309 is rotatably connected to the inner wall of the positioning cylinder 310. The connecting gear 308 meshes with the tooth groove 311 on the inner wall of the rotating drum 306. The rotation of the connecting gear 308 will drive the rotating drum 306 to rotate around the fixed cylinder 305. Because the diameter ratio of the driving gear 304 to the rotating drum 306 is 1:3, according to the gear transmission principle, this structure can improve the torque of the motor. Under the same power input, the rotating drum 306 can obtain a greater torque.

[0030] Furthermore, a connecting plate 312 is fixedly connected to the end of the rotating drum 306 away from the servo motor 301. A connecting rod 313 is fixedly connected to the side of the connecting plate 312 away from the rotating drum 306. The end of the connecting rod 313 away from the connecting plate 312 is fixedly connected to the rotating roller 201. The connecting plate 312 is fixedly connected to the rotating roller 201 through the connecting rod 313. Therefore, when the rotating drum 306 rotates, it will drive the rotating roller 201 to rotate through the connecting plate 312 and the connecting rod 313.

[0031] Since the rotating roller 201 is located between the connecting plate 102 and the support frame 2, and the connecting plate 102 is connected to the LED module 1, and the support frame 2 is a fixed structure, the rotation of the rotating roller 201 will drive the connecting plate 102 and the connected LED module 1 to rotate together, thereby controlling the angle of the LED floodlight.

[0032] The planetary gear structure (a gear transmission system consisting of driving gear 304, connecting gear 308, and rotating drum 306) enables more precise transmission ratio control, allowing the rotation angle of LED module 1 (i.e., LED floodlight part) to be adjusted more precisely according to design requirements, meeting the needs of modern lighting for precise angle control.

[0033] By utilizing the characteristic that the diameter ratio of the drive gear 304 to the rotating drum 306 is 1:3, the torque is effectively increased through gear transmission based on the output power of the servo motor 301. Even when driving the relatively heavy LED module 1 and other auxiliary structures (such as the heat sink 103), stable rotation can be guaranteed, thus improving the reliability and stability of the device.

[0034] Because it can achieve efficient and precise angle control, and has good stability and reliability, this LED floodlight control device can adapt to a variety of different lighting scenarios, such as large stadium lighting and outdoor billboard lighting, and meet the needs of light angle adjustment in different environments.

[0035] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
