Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, and specifically to an energy-saving, multi-angle adjustable lighting device with COB light strips. Background Technology

[0002] COB LED strips themselves have high luminous efficacy, producing high brightness with relatively low power consumption. At the same time, these lighting devices are usually equipped with energy-efficient power drivers, which effectively reduce power loss. Some also support dimming functions, allowing users to adjust the brightness according to their actual needs, further reducing energy consumption and extending the lifespan of the lamps.

[0003] Currently available lighting equipment is generally fixed to equipment or walls for illumination, which has limited lighting effect and fixed position, and cannot meet the requirements of illumination from different angles. Therefore, an energy-saving lighting device with COB light strip and multi-angle adjustable is provided. Summary of the Invention

[0004] This invention provides an energy-saving, multi-angle adjustable lighting device with COB LED strip, aiming to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving, multi-angle adjustable lighting device with COB light strip, comprising a reinforcing frame on which a controllable lighting component is configured.

[0006] The adjustable lighting assembly includes several angle-adjustable deflection frames disposed on the outside of the reinforcing frame. Each deflection frame is connected to an angle-adjustable deflection plate at the end away from the reinforcing frame. The cross-sections of the deflection plates and the deflection frames are both arc-shaped, and a first light strip is installed on the outside of the deflection frames and the deflection plates, respectively.

[0007] The top of the reinforcing frame is provided with a lead screw, and the bottom of the lead screw is connected by a thread to a second connecting plate that can move up and down along the axis of the lead screw. The top of the lead screw is rotatably connected to a first connecting plate. Several extension rods are fixedly connected to the outer sides of the lead screw and the second connecting plate, respectively. A second light strip is installed at the end of the multiple extension rods away from the lead screw and the second connecting plate. Both the first light strip and the second light strip are COB light strips.

[0008] The bottom of the deflection frame has a misaligned cavity, the shape and size of which are adapted to the deflection plate. An electric push rod is hinged inside the misaligned cavity. The fixed end of the electric push rod is rotatably connected to the inner wall of the misaligned cavity through a hinge shaft. An arc-shaped guide rail is provided on the side of the deflection plate away from the first light strip. A slider is hinged to the output end of the electric push rod. The slider is embedded in the guide rail groove of the arc-shaped guide rail, and the slider and the arc-shaped guide rail form a sliding fit. The slider can slide along the length direction of the guide rail groove of the arc-shaped guide rail.

[0009] The reinforcing frame is rotatably connected to a rotating shaft via a bearing in the middle. Several gears are arranged on the outer circumference of the rotating shaft, and the gears are spaced apart along the axial direction of the rotating shaft. Multiple gears and deflection frames are stacked along the axial direction of the rotating shaft, and a misalignment opening is formed between two adjacent deflection frames. The space size of the misalignment opening is large enough to accommodate the other deflection frames, realizing the storage function of the deflection frames. An arc-shaped rack is provided at the end of the deflection frame away from the deflection plate. The gear and the arc-shaped rack are in the same horizontal plane, and the teeth of the gear and the teeth of the arc-shaped rack mesh with each other. When the gear rotates, it can drive the arc-shaped rack to move synchronously.

[0010] The deflection frame and the deflection plate are rotatably connected by a hinge plate. One end of the hinge plate is fixedly connected to the deflection frame, and the other end is rotatably connected to the deflection plate via a hinge shaft. The end of the deflection frame away from the deflection plate is rotatably connected to a limit shaft via a bearing. The reinforcing frame has a shaft hole adapted to the limit shaft. The end of the limit shaft away from the deflection frame is inserted into the shaft hole of the reinforcing frame, and the limit shaft can rotate within the shaft hole. A first motor for driving the rotating shaft is installed on the top of the reinforcing frame. The output shaft of the first motor is fixedly connected to one end of the rotating shaft via a coupling. A drive screw for driving the rotation is installed on the top of the first motor via a bracket. The second motor has its output shaft fixedly connected to a lead screw via a coupling. Several slide rails are inserted into the bottom of the first connecting plate. These slide rails are evenly distributed along the circumference of the first connecting plate, and each slide rail passes through the second connecting plate vertically and extends to the housing of the second motor. The second connecting plate has sliding holes that match the slide rails. The second connecting plate slides up and down along the length of the slide rails through the sliding holes. The reinforcing frame is a rectangular frame structure. Each deflection frame is symmetrically distributed with the axis of rotation as the center of symmetry, and the deflection frames maintain a preset distance from the outer wall of the reinforcing frame.

[0011] The present invention has the following advantages: 1. The present invention uses a double-layer angle adjustment structure. The outer layer drives the rotating shaft through the first motor to rotate the gear. The gear meshes with the arc-shaped rack on the deflection frame to realize a wide range of rotation of the deflection frame around the limiting axis. The inner layer relies on the electric push rod in the misalignment cavity of the deflection frame to push the slider to slide along the arc-shaped guide rail of the deflection plate, thereby driving the deflection plate to be precisely adjusted around the hinge plate.

[0012] 2. Based on the double-layer angle adjustment structure, this invention uses a top lead screw structure in conjunction with a second motor to drive the second connecting plate and the second light strip on the extension rod to achieve height adjustment. Furthermore, the radial extension of the extension rod further expands the lighting coverage. This three-dimensional adjustment system of deflection frame, deflection plate, and height adjustment completely breaks the limitations of fixed angles in traditional lighting equipment. It can meet the needs of multi-area ambient lighting in family living rooms, multi-angle display lighting for goods in commercial stores, and directional lighting requirements for different workstations in industrial workshops, achieving full adaptability to lighting scenarios. Simultaneously, by adjusting the angle of the deflection frame and deflection plate, as well as the height of the second light strip, the light can be precisely focused on the target area without activating all lighting components, avoiding energy waste.

[0013] 3. The offset cavity at the bottom of the deflection frame of this invention matches the size of the deflection plate. When not in use, the deflection plate can be completely embedded in the cavity, reducing the thickness of a single lighting unit. Simultaneously, the pre-reserved offset openings between adjacent deflection frames allow for the embedding of other deflection frames during equipment storage or transportation, significantly compressing the overall volume. This offset nesting storage design allows the equipment to adapt to different space sizes during installation. The stored equipment occupies less space and further allows the individual first light strips to be stacked together, achieving the function of increasing light intensity with the same power.

[0014] In summary, the gear meshes with the arc-shaped rack on the deflection frame, enabling the deflection frame to rotate a wide range around the limiting axis. The inner layer relies on the electric push rod in the misaligned cavity of the deflection frame to push the slider to slide along the arc-shaped guide rail of the deflection plate, thereby driving the deflection plate to precisely adjust around the hinge plate. At the same time, by adjusting the angle of the deflection frame, the deflection plate, and the height of the second light strip, the light can be precisely focused on the target area without turning on all lighting components, thus avoiding energy waste. In addition, the misaligned nested storage design allows the device to adapt to different space sizes during installation. The device in the stored state reduces space occupation and further allows the various first light strips to be stacked together, achieving the function of increasing the light intensity with the same power.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This embodiment discloses an energy-saving, multi-angle adjustable lighting device with COB LED strips, aiming to solve the problems of existing lighting devices having fixed positions, single lighting angles, and inability to meet the lighting needs of different scenarios. Through a reasonable structural design, this device achieves multi-dimensional adjustment of the lighting angle. Simultaneously, by using COB LED strips as the light source, it combines energy saving and high luminous efficiency, and can be widely applied to various scenarios such as home lighting, commercial lighting, and industrial lighting.

[0026] like Figure 1As shown, the core supporting component of this lighting equipment is the reinforcing frame 1. The reinforcing frame 1 adopts a rectangular frame structure, and the profiles are connected into one piece through welding, which ensures the stability of the overall structure and has lightweight characteristics, making it easy to install and transport the equipment. A rotating shaft 7 is rotatably connected to the middle of the reinforcing frame 1 via a deep groove ball bearing.

[0027] like Figure 4 , Figure 5 As shown, several deflection frames 2 are spaced apart on the outer side of the reinforcing frame 1 along the axis of the rotating shaft 7, and each deflection frame 2 has an arc-shaped structure. The end of the deflection frame 2 away from the reinforcing frame 1 is rotatably connected to the deflection plate 3 through a hinge plate 10. One end of the hinge plate 10 is fixed to the deflection frame 2 by bolts, and the other end is connected to the deflection plate 3 through a stainless steel hinge shaft.

[0028] The deflection plate 3 is also an arc-shaped structure, matching the curvature of the deflection frame 2. The first light strip 6 is fixedly installed on its outer side by a combination of double-sided adhesive and buckles. The first light strip 6 can be a 12V low-voltage COB light strip, which can reduce energy consumption while ensuring high brightness.

[0029] like Figure 5 , Figure 6 As shown, a misaligned cavity 18 is provided at the bottom of the deflection frame 2. The depth of the misaligned cavity 18 is the same as the thickness of the deflection plate 3, and the width is slightly larger than the width of the deflection plate 3, ensuring that the deflection plate 3 can be completely embedded in the misaligned cavity 18 to achieve the storage function. An electric push rod 5 is fixedly hinged to the side of the misaligned cavity 18 near the reinforcing frame 1 via a hinge shaft. The electric push rod 5 is a miniature electric push rod of model XTL100, which can meet the angle adjustment requirements of the deflection plate 3. An arc-shaped guide rail 4 is fixedly installed on the side of the deflection plate 3 away from the first light strip 6 via bolts. The arc of the arc-shaped guide rail 4 is the same as the arc of the deflection plate 3. The output end of the electric push rod 5 is connected to a slider via a hinge block. The slider is embedded in the arc-shaped guide rail 4 and can slide along the guide rail groove. When the output end of the electric push rod 5 extends or retracts, the slider slides along the arc-shaped guide rail 4, thereby driving the deflection plate 3 to rotate around the hinge shaft of the hinge plate 10, realizing the adjustment of the lighting angle of the deflection plate 3.

[0030] like Figure 4 , Figure 7As shown, several gears 8 are fixedly mounted on the outer circumference of the rotating shaft 7 via key connections. Each gear 8 corresponds to a deflection frame 2 and they are stacked along the axial direction of the rotating shaft 7. An arc-shaped rack 9 is fixedly connected to the end of the deflection frame 2 away from the deflection plate 3 via welding, and both are on the same horizontal plane. The teeth of the gears 8 and the teeth of the arc-shaped rack 9 are fully engaged. A limit shaft 20 is also rotatably connected to the end of the deflection frame 2 away from the deflection plate 3 via a rolling bearing. A shaft hole with a diameter matching that of the limit shaft 20 is provided on the reinforcing frame 1. The limit shaft 20 is inserted into the shaft hole and can rotate freely within it, providing guidance and support for the rotation of the deflection frame 2.

[0031] The top of the reinforcing frame 1 is bolted to a first motor 11, which is a 57BYG250 stepper motor, and is fixedly connected to one end of the rotating shaft 7 via a coupling. When the first motor 11 starts, its output shaft drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the gear 8 to rotate synchronously. The gear 8, through meshing with the arc-shaped rack 9, drives the arc-shaped rack 9 to rotate the deflection frame 2 around the axis of the limiting shaft 20, thereby adjusting the lighting angle of the deflection frame 2. At the same time, a misalignment opening 19 is formed between two adjacent deflection frames 2. When the deflection frame 2 rotates to a specific angle, the other deflection frames 2 can be inserted into the misalignment opening 19, reducing the space occupied by the equipment, facilitating storage and transportation, and further enabling the various first light strips 6 to be stacked together, achieving the function of increasing the light intensity with the same power.

[0032] like Figure 1 , Figure 3As shown, a second motor 12 is bolted to the top of the reinforcing frame 1. The second motor 12 is a stepper motor of the same model as the first motor 11, and its output shaft is fixedly connected to the lead screw 13 via a coupling. A second connecting plate 15 is threaded to the bottom of the lead screw 13, and an internal thread hole matching the thread of the lead screw 13 is opened in its center. A first connecting plate 14 is rotatably connected to the top of the lead screw 13 via a bearing. The first connecting plate 14 and the second connecting plate 15 have the same diameter, and several slide rails are bolted to its bottom. The slide rails are linear optical axes, evenly distributed along the circumference of the first connecting plate 14, and pass through the second connecting plate 15 vertically, extending to the housing of the second motor 12 and fixed with bolts. The second connecting plate 15 has a sliding hole matching the diameter of the slide rail, and a linear bearing is installed in the sliding hole. The second connecting plate 15 and the slide rail form a sliding fit through the linear bearing, allowing it to slide smoothly up and down along the length of the slide rail. Several extension rods 16 are bolted to the outer sides of the lead screw 13 and the second connecting plate 15, evenly distributed along the circumference of the lead screw 13 and the second connecting plate 15. A second light strip 17 is fixedly installed at the end of each extension rod 16 away from the lead screw 13 and the second connecting plate 15 via a clip. The second light strip 17 is of the same model as the first light strip 6, achieving radial lighting extension. When the second motor 12 starts, its output shaft drives the lead screw 13 to rotate. Due to the restriction of the slide rail, the second connecting plate 15 cannot rotate synchronously with the lead screw 13, but can only move up and down along the axis of the lead screw 13, thereby driving the extension rods 16 and the second light strip 17 to move up and down, achieving adjustment of the lighting height of the second light strip 17. Simultaneously, the extension rods 16 allow the second light strip 17 to achieve radial lighting coverage, further expanding the lighting range.

[0033] The specific working principle is as follows: When it is necessary to adjust the illumination angle of the deflection plate 3, the electric push rod 5 is activated. The output end of the electric push rod 5 extends or retracts, causing the slider at its end to slide along the arc-shaped guide rail 4 on the deflection plate 3. Since the deflection plate 3 is rotatably connected to the deflection frame 2 through the hinge plate 10, the sliding of the slider will cause the deflection plate 3 to rotate around the hinge axis of the hinge plate 10, thereby changing the illumination angle of the first light strip 6. By controlling the extension or retraction length of the output end of the electric push rod 5, the angle of the deflection plate 3 can be adjusted to the required position to meet the illumination needs in different directions.

[0034] When the illumination angle of the deflection frame 2 needs to be adjusted, the first motor 11 is started. The output shaft of the first motor 11 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the gear 8 on it to rotate synchronously. The gear 8, through meshing with the arc-shaped rack 9 on the deflection frame 2, drives the arc-shaped rack 9 to drive the deflection frame 2 to rotate around the axis of the limiting shaft 20, thereby changing the illumination angle of the deflection frame 2, the deflection plate 3 mounted on it, and the first light strip 6. By controlling the rotation direction and rotation angle of the first motor 11, the angle of the deflection frame 2 can be precisely adjusted, realizing multi-dimensional illumination angle adjustment.

[0035] When the illumination height of the second light strip 17 needs to be adjusted, the second motor 12 is started, and the output shaft of the second motor 12 drives the lead screw 13 to rotate. Since the second connecting plate 15 is threadedly connected to the lead screw 13 and is restricted by the guide rail, it cannot rotate with the lead screw 13, but can only slide up and down along the axis of the lead screw 13. The up-and-down sliding of the second connecting plate 15 causes the extension rod 16, which is fixedly connected to it, and the second light strip 17 to move up and down synchronously, thereby adjusting the illumination height of the second light strip 17. Simultaneously, the radial extension of the extension rod 16 allows the second light strip 17 to cover a wider area. Combined with the angle of the second light strip 17 itself, and further optimized by setting an angle adjustment structure at the end of the extension rod 16, this embodiment defaults to a fixed angle for the second light strip 17, but it can be extended according to actual needs to achieve radial illumination coverage, further improving the illumination range and flexibility of the equipment.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
