The structure includes a base with a ring-shaped structure; a shell with a connecting rod fixedly connected to its inner wall surface; a connecting seat fixedly connected to the outer end of the connecting rod in the middle of the shell; and a ball head fixedly connected to the bottom end of the connecting seat, the ball head being a hollow structure. This energy-saving fluorescent lighting structure based on an embedded rotating structure effectively solves the problem in existing technologies where, during construction, deformation of the wall and ceiling formwork, uneven plaster thickness, and errors in ceiling joist installation easily lead to deviations in the horizontal plane of the wall and ceiling.

Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more specifically to an energy-saving fluorescent lighting structure based on an embedded rotating structure. Background Technology

[0002] In modern architecture, commercial spaces, and home environments, lighting systems are not only functional facilities that provide basic illumination, but also key elements in creating spatial atmosphere and enhancing design aesthetics. Fluorescent lighting fixtures, with their superior energy efficiency compared to traditional incandescent bulbs, have become the mainstream solution in the field of general lighting over the past few decades, and are widely used in commercial buildings, industrial plants, public spaces, and residential settings.

[0003] In existing technologies, during the construction process, due to deformation of the wall and top formwork, uneven thickness of the plaster layer, and installation errors of the ceiling joists, the wall and top are prone to deviations in plane levelness. Traditional lighting structures generally adopt a rigid fixed design, directly locked to the wall and top, lacking the ability to adaptively adjust to structural deviations. This causes the light projection angle to deviate from the design value, forming dark areas or glare, and affecting the uniformity of lighting. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides an energy-saving fluorescent lighting structure based on an embedded rotating structure. This structure effectively solves the problem that, during construction, variations in wall and ceiling formwork deformation, uneven plaster thickness, and ceiling joist installation errors can easily lead to deviations in the horizontal plane of the wall and ceiling. Traditional lighting structures generally employ a rigid, fixed design, directly locking themselves to the wall and ceiling, lacking the ability to adaptively adjust to structural deviations. This causes the light projection angle to deviate from the design value, resulting in dark areas or glare, and affecting the uniformity of lighting.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides an energy-saving fluorescent lighting structure based on an embedded rotating structure, comprising: The base has a ring-shaped structure; The housing has a connecting rod fixedly connected to its inner wall surface, a connecting seat fixedly connected to the outer end of the connecting rod in the middle of the housing, a ball head fixedly connected to the bottom end of the connecting seat, the ball head having a hollow structure design, an arc groove opened on the lower surface of the housing, and a guide groove communicating with the inside of the arc groove opened on the inner wall surface of the housing. A substrate has a spherical arc plate fixedly connected to its center, which fits against the outer circumference of the ball head. An adjustment mechanism for adjusting the angle of the substrate is provided inside the housing. The outer surface of the ball head and the inner surface of the spherical arc plate are designed concentrically. Energy-saving fluorescent lamp beads are welded to the lower surface of the substrate.

[0006] Furthermore, the adjusting component includes a ball groove seat fixed to the upper surface of the substrate, a support plate fixedly connected to the inner wall surface of the housing, a gear rotatably connected to the upper surface of the support plate, a ball rollingly connected inside the ball groove seat, a threaded rod fixedly connected to the upper surface of the ball through the middle of the gear, and a threaded groove that meshes with the outer surface of the threaded rod on the inner circumference of the gear.

[0007] Furthermore, the arc-shaped groove is internally damped and slidably connected to a toggle block, and the upper surface of the toggle block is fixedly connected to a slider that fits against the inner wall surface of the guide groove. The side of the slider near the connecting seat is fixedly connected to an arc-shaped rack that meshes with the outer surface of the gear.

[0008] Furthermore, two ball groove seats are provided, and the two ball groove seats are distributed at a 90-degree angle with the ball head as the center.

[0009] Furthermore, the inner wall surface of the base is provided with a slot, and a support plate is fixedly connected to the upper surface of the housing. The support plate is slidably connected to a connector via a slide rail provided on its upper surface.

[0010] Furthermore, the connector includes a vertical rod, the bottom end of which passes through the interior of the connector and the ball head and extends to the bottom of the ball head. A connecting rod is rotatably connected to the outer circumferential surface of the vertical rod. A card plate that fits against the inner wall surface of the card slot is rotatably connected to the end of the connecting rod away from the vertical rod. The card plate is slidably connected to the upper surface of the support plate through a groove formed on its lower surface.

[0011] Furthermore, an annular cavity is formed on the upper surface of the connecting seat, and a ring plate is fixedly connected to the outer circumference of the vertical rod. A spring connected to the lower surface of the ring plate is provided inside the annular cavity.

[0012] Furthermore, the bottom of the inner wall of the base is designed to be inclined, and a lampshade is fixedly installed on the lower surface of the housing.

[0013] The technical solution provided by this invention has the following advantages compared with the prior art: This invention comprises a housing, a ball head, a base plate, a spherical arc plate, and an adjusting component. Existing lighting fixtures are mostly rigidly fixed designs, permanently connected to the wall or ceiling. When there is a levelness deviation in the wall or ceiling, the base, housing, and base plate will tilt accordingly, causing light spot shift, uneven illuminance, and creating blind spots. In this invention, the ball head and the spherical arc plate in the middle of the base plate are concentric. In the adjusting component, by moving a toggle block, the slider and arc-shaped rack move, which in turn drives the gear to rotate, causing the threaded rod to move up and down. This applies a pushing or pulling force to the base plate through the ball groove seat, causing the base plate to rotate around a specific connecting line as its axis of rotation. This precisely counteracts the tilt deviation of the wall or ceiling, restoring the base plate to a level state. After adjustment, the light from the energy-saving fluorescent lamp beads can shine vertically downwards, providing uniform illumination and eliminating the lighting problems caused by wall or ceiling deviations. The two ball-shaped bases and their matching adjustment components are distributed at a 90-degree angle, enabling the substrate to rotate in multiple dimensions around different axes. This allows it to handle scenarios with different horizontal deviations from the ceiling at different angles. The adjustment angle range is wide and can accurately compensate for tilt errors in any direction (front and back, left and right, or a combination of directions) of the ceiling. After adjustment, the substrate is corrected to a horizontal state, ensuring that the light-emitting surface always remains horizontal and the light is projected vertically downwards, thereby ensuring the uniformity and standardization of the lighting area and improving the final lighting quality.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] The present invention will be further described below with reference to embodiments.

[0019] Example: Please see Figures 1-9 This invention provides a technical solution: an energy-saving fluorescent lighting structure based on an embedded rotating structure, comprising: Base 1, base 1 has a ring structure; The housing 2 has a connecting rod 21 fixedly connected to its inner wall surface. A connecting seat 22 fixedly connected to the outer end of the connecting rod 21 is provided in the middle of the housing 2. A ball head 23 is fixedly connected to the bottom end of the connecting seat 22. The ball head 23 adopts a hollow structure design. An arc groove 241 is provided on the lower surface of the housing 2. A guide groove 242 communicating with the inside of the arc groove 241 is provided on the inner wall surface of the housing 2. The substrate 3 has a spherical arc plate 31 fixedly connected to its middle part, which is in contact with the outer circumference of the ball head 23. The housing 2 has an adjustment member 32 for adjusting the angle of the substrate 3.

[0020] The outer surface of the ball head 23 and the inner surface of the ball arc plate 31 are designed with a concentric structure.

[0021] The adjusting component 32 includes a ball groove seat 321 fixed on the upper surface of the base plate 3, a support plate 322 fixedly connected to the inner wall surface of the housing 2, a gear 323 rotatably connected to the upper surface of the support plate 322, a ball ball 324 rollingly connected inside the ball groove seat 321, a threaded rod 325 passing through the middle of the gear 323 fixedly connected to the upper surface of the ball ball 324, and a threaded groove that meshes with the outer surface of the threaded rod 325 on the inner circumference of the gear 323.

[0022] An actuating block 326 is slidably connected inside the arc groove 241. A slider 327 that fits against the inner wall surface of the guide groove 242 is fixedly connected to the upper surface of the actuating block 326. An arc-shaped rack 328 that meshes with the outer surface of the gear 323 is fixedly connected to the side of the slider 327 near the connecting seat 22.

[0023] The outer surface of the housing 2 is provided with a zero-degree scale line in the middle of the arc groove 241, and the outer surface of the toggle block 326 is provided with a pointer in the middle. When both toggle blocks 326 are located in the middle of the arc groove 241, that is, when the pointers on the outer surfaces of both toggle blocks 326 are aligned with the zero-degree scale line, the base plate 3 and the base 1 are completely parallel.

[0024] There are two ball groove seats 321, which are distributed at a 90-degree angle with the ball head 23 as the center.

[0025] The inner wall surface of the base 1 is provided with a slot 11, and the upper surface of the housing 2 is fixedly connected with a support plate 25. The support plate 25 is slidably connected with a connector 26 via a slide rail provided on its upper surface.

[0026] The connector 26 includes a vertical rod 261. The bottom end of the vertical rod 261 passes through the interior of the connector 22 and the ball head 23 and extends to the bottom of the ball head 23. A connecting rod 262 is rotatably connected to the outer circumferential surface of the vertical rod 261. A card plate 263 that fits against the inner wall surface of the card slot 11 is rotatably connected to the end of the connecting rod 262 away from the vertical rod 261. The card plate 263 is slidably connected to the upper surface of the support plate 25 through a groove formed on its lower surface.

[0027] The upper surface of the connecting seat 22 is provided with an annular cavity 221, and the outer circumference of the vertical rod 261 is fixedly connected with a ring plate 264. The annular cavity 221 is provided with a spring 265 connected to the lower surface of the ring plate 264.

[0028] The bottom of the inner wall of the base 1 is designed with an inclination, and the lampshade 27 is fixedly installed on the lower surface of the housing 2.

[0029] Pre-assembly process of base 1: The base 1 is fixed to the top of the wall using expansion bolts, ensuring that the annular end face of the base 1 is flush with the surface of the top wall, thus completing the installation foundation fixing of the entire structure. At this time, the slot 11 of the base 1 faces inward, and the inclined surface at the bottom of the inner wall provides guidance for the insertion of the housing 2.

[0030] Distribution of internal structure of shell 2: One end of the connecting rod 21 is welded and fixed to the inner wall of the housing 2, and the other end is welded to the outer wall of the connecting seat 22, so that the connecting seat 22 is located at the center of the housing 2. The top end of the ball head 23 and the bottom end of the connecting seat 22 are integrally formed. The ball head 23 is a hollow structure (for vertically sliding the vertical rod 261), and the axis of the ball head 23 is coaxial with the connecting seat 22.

[0031] A support plate 322 is fixedly connected to the inner wall surface of the housing 2, and a gear 323 is rotatably mounted on the support plate 322 via a connecting bearing. An arc-shaped rack 328 is fixed to a slider 327, which is embedded in a guide groove 242 to ensure meshing between the arc-shaped rack 328 and the outer surface of the gear 323. A toggle block 326 is embedded from below the housing 2 into an arc-shaped groove 241 and fixed to the bottom end of the slider 327. At this time, the toggle block 326 can slide damped along the arc-shaped groove 241, causing the arc-shaped rack 328 to move synchronously, thereby driving the gear 323 to rotate.

[0032] An annular plate 264 is fitted onto and fixedly connected to the vertical rod 261. A spring 265 is placed inside the annular cavity 221 of the connecting seat 22. The vertical rod 261 passes through the middle top of the connecting seat 22, sequentially through the hollow channel of the connecting seat 22 and the ball head 23, and extends to below the ball head 23. Four connecting rods 262 are rotatably connected to the outer circumference of the top of the vertical rod 261. The other end of the connecting rods 262 is rotatably connected to the clamping plate 263. The sliding groove of the clamping plate 263 cooperates with the sliding rail of the support plate 25, allowing the clamping plate 263 to slide horizontally along the support plate 25.

[0033] The ball-shaped arc plate 31 is fixed to the center of the base plate 3 (the base plate 3 is a hollow annular plate), ensuring that the inner surface of the ball-shaped arc plate 31 is in contact with and concentric with the outer surface of the ball head 23. Two ball groove seats 321 are welded to the upper surface of the base plate 3, and the two ball groove seats 321 are distributed at a 90-degree angle with the ball head 23 as the center. The ball 324 is placed in the ball groove seat 321, and the bottom end of the threaded rod 325 is fixedly connected to the ball 324, and the top end passes through the central threaded hole of the gear 323, so that the threaded rod 325 meshes with the threaded groove on the inner wall of the gear 323. At this time, the base plate 3 is suspended below the housing 2 through the cooperation of the ball-shaped arc plate 31 and the ball head 23. Rotating the actuating block 326 can drive the base plate 3 to rotate around the ball head 23.

[0034] The fluorescent lamp beads are soldered onto the substrate 3, and the circuitry extends from the top of the substrate 3, passes through the inside of the housing 2, and connects to an external power source. The lamp cover 27 is fixedly mounted to the lower surface of the housing 2 using clips.

[0035] The process of installing housing 2: The bottom end of the vertical rod 261 extends to the lower surface of the lampshade 27, and the bottom end has a spherical design. In the initial state, the spring 265 inside the annular cavity 221 is in the unfolded state, and through the annular plate 264 at its upper end, it drives the vertical rod 261 to the highest point within its stroke range. At this time, the connecting rod 262 on the outer circumference of the vertical rod 261 is in a horizontal state, and pushes multiple clamping plates 263 to unfold outward and fit against the upper surface of the support plate 25. The outer surface of the clamping plate 263 away from the vertical rod 261 adopts an arc design, and the outer surface of the clamping plate 263 away from the vertical rod 261 protrudes from the outer circumference of the housing 2. At this time, the circular area enclosed by the multiple clamping plates 263 is the largest, and the distance between the arc-shaped outer surface of the clamping plate 263 and the axis of the vertical rod 261 is greater than the radius of the housing 2.

[0036] During installation, use one hand to support the housing 2 through the lampshade 27, and the other hand to pull down the bottom end of the vertical rod 261 protruding from the lower surface of the lampshade 27. During this process, the annular plate 264, fixedly connected to the outer circumference of the vertical rod 261, moves downwards synchronously. The connecting seat 22, through the connecting rod 21, remains fixedly connected to the inner wall of the housing 2. As the annular plate 264 moves downwards, the connecting seat 22 remains stationary, and the spring 265 inside the annular cavity 221 is compressed. The downward movement of the vertical rod 261 causes the connecting rod 262 to rotate. The end of the connecting rod 262 closest to the center of the housing 2 moves downwards synchronously with the vertical rod 261. Since the locking plate 263 always slides horizontally along the slide rail on the upper surface of the support plate 25, the end of the connecting rod 262 furthest from the center of the housing 2 remains on the same horizontal plane as the locking plate 263. At this time, the connecting rod 262 is in a lower inclined state near the end of the vertical rod 261, and pulls the locking plate 263 to retract along the slide rail of the support plate 25 towards the centerline of the housing 2.

[0037] At this time, the connector 26 is in a retracted state, and the distance from the outer surface of the clamping plate 263 to the axis of the housing 2 is less than the radius of the housing 2. The lampshade 27 is supported and the housing 2 is embedded into the interior of the base 1. The bottom of the inner wall of the base 1 is provided with an inclined surface. The inner diameter of the bottom of the inner wall of the base 1 is the largest near the bottom and gradually decreases near the top, which plays a guiding role and facilitates the quick alignment of the housing 2.

[0038] Once the upper surface of the locking plate 263 is fully engaged with the top of the inner wall of the base 1, the vertical rod 261 is released. The spring 265 returns to its original position, pushing the ring plate 264 upward. The connecting rod 262 drives the locking plate 263 to slide outward until the locking plate 263 is embedded in the slot 11 of the base 1, thus securing the housing 2 to the base 1. A rubber strip is provided on the outer surface of the locking plate 263 away from the vertical rod 261, which adheres to the inner wall surface of the slot 11. In this state, the side of the locking plate 263 away from the vertical rod 261 is embedded inside the slot 11, and the rubber strip on the outer surface of the locking plate 263 undergoes slight deformation under pressure. At this point, the housing 2 has completed the rapid assembly with the base 1.

[0039] The process of adjusting the angle based on the horizontal deviation of the top of the wall: After installation, if the wall and top are level, the pointers of the two toggle blocks 326 are aligned with the zero-degree scale line of the arc groove 241. The toggle block 326 is centered in the middle of the arc groove 241. At this time, the substrate 3 is parallel to the base 1, and the light from the fluorescent lamp beads shines vertically downwards, resulting in a uniform illumination area.

[0040] Taking the horizontal deviation of the top of the wall being higher on the left and lower on the right as an example, two ball groove seats 321 are provided on the upper surface of the substrate 3. The two ball groove seats 321 are distributed at a 90-degree angle with the ball head 23 as the center. At this time, one ball groove seat 321 is located on the left and the other ball groove seat 321 is located in front.

[0041] When there is a level deviation of the wall top with the left side higher and the right side lower, the shell 2 tilts with the wall top, and the base plate 3 also tilts with the left side higher and the right side lower, causing the light to shift to the left, resulting in excessive lighting on the left side and a blind spot on the right side.

[0042] One of the ball groove seats 321 is located on the left side, and its matching arc groove 241 is also located on the left side of the housing 2. The operator pushes the left-side actuating block 326 to slide clockwise along the arc groove 241. The actuating block 326 drives the slider 327 to slide along the guide groove 242. Simultaneously, the arc rack 328 moves clockwise around the axis of the housing 2, driving the gear 323 meshing with it to rotate clockwise. The internal thread of the gear 323 drives the threaded rod 325 to move downward. The threaded rod 325 rolls in the ball groove seat 321 through the ball 324, applying a downward thrust to the left side of the base plate 3.

[0043] Since the base plate 3 is concentrically engaged with the ball head 23 via the ball arc plate 31, under the thrust of the threaded rod 325 on the left, the base plate 3 rotates to the left around the connecting line from the center of the ball head 23 to the center of the ball in the ball groove seat 321 directly in front. During this process, the ball groove seat 321 directly in front, its internal balls 324, and the threaded rod 325 remain in fixed positions, and the actuating block 326 in front is centered in the arc groove 241, with the pointer of the actuating block 326 aligned with the zero-degree scale line of the arc groove 241.

[0044] During adjustment, observe the relative positions of the pointers and scale lines of the two toggle blocks 326. When the pointer of the left toggle block 326 deviates from the zero-degree scale line and moves clockwise, while the pointer of the front toggle block 326 remains stationary, the substrate 3 rotates to the left, precisely offsetting the tilt deviation of the wall top. At this point, the substrate 3 returns to a horizontal state. Releasing the toggle blocks 326, due to the damping engagement between the arc-shaped groove 241 and the toggle blocks 326, keeps the toggle blocks 326 in their current position, and the angle of the substrate 3 is locked.

[0045] In summary, when the base 1 is higher on the left and lower on the right, the left-side toggle block 326 is turned clockwise. This causes the slider 327 and the arc-shaped rack 328 to rotate the gear 323 clockwise, causing the left-side threaded rod 325 to be vertically downward relative to the support plate 322. The front toggle block 326 is fixed in this position. The base plate 3 rotates to the left about the line connecting the center of the ball head 23 to the center of the ball in the ball groove seat 321 directly in front, so that the base plate 3 returns to a horizontal state.

[0046] Correspondingly, when the base 1 is lower on the left and higher on the right, the left-side toggle block 326 is turned counterclockwise. This causes the slider 327 and the arc-shaped rack 328 to rotate the gear 323 counterclockwise, causing the left-side threaded rod 325 to be vertically upward relative to the support plate 322. The front toggle block 326 is fixed in this position. The base plate 3 rotates to the right about the line connecting the center of the ball head 23 to the center of the ball in the ball groove seat 321 directly in front, so that the base plate 3 returns to a horizontal state.

[0047] When the base 1 is higher in the front and lower in the back, the front toggle block 326 is turned clockwise. The slider 327 and the arc rack 328 drive the gear 323 to rotate clockwise, causing the front threaded rod 325 to be vertically downward relative to the support plate 322. The left toggle block 326 is fixed in this position. The base plate 3 rotates forward about the line connecting the center of the ball head 23 to the center of the ball in the ball groove seat 321 on the left, so that the base plate 3 returns to the horizontal state.

[0048] When the base 1 is lower in the front and higher in the back, the front toggle block 326 is turned counterclockwise. This causes the slider 327 and the arc rack 328 to rotate the gear 323 counterclockwise, which in turn causes the front threaded rod 325 to be vertically upward relative to the support plate 322. The left toggle block 326 is fixed in this position. The base plate 3 rotates backward about the line connecting the center of the ball head 23 to the center of the ball in the ball groove seat 321 on the left, so that the base plate 3 returns to a horizontal state.

[0049] When the base 1 is higher on the left front and lower on the right rear, turn the left toggle block 326 clockwise. This causes the slider 327 and the arc rack 328 to rotate the gear 323 clockwise, causing the left threaded rod 325 to be vertically downward relative to the support plate 322. Turn the front toggle block 326 clockwise. This causes the slider 327 and the arc rack 328 to rotate the gear 323 clockwise, causing the front threaded rod 325 to be vertically downward relative to the support plate 322. The inner wall surface of the spherical arc plate 31 in the middle of the base plate 3 is always in contact with the outer circumference of the ball head 23. Rotate to the left front to restore the base plate 3 to a horizontal state.

[0050] After adjustment, the light from the fluorescent lamp beads returns to vertical downward illumination, resulting in uniform lighting coverage. This eliminates lighting problems caused by wall and ceiling deviations, and lighting needs can be met without increasing lamp power, achieving energy-saving effects.

[0051] The process of disassembling and assembling the light fixture: The operator holds the lampshade 27 with their hand and pulls the bottom of the vertical rod 261 from below. The vertical rod 261 moves downward, compressing the spring 265 on the ring plate 264. The connecting rod 262 rotates under the action of the vertical rod 261, pulling the locking plate 263 to retract towards the center and disengage it from the locking groove 11 of the base 1. At this time, the housing 2 is released from the base 1, and the housing 2 is removed from the base 1 and lowered to the ground for maintenance.

[0052] In summary, this lighting structure has the following advantages: Advantage 1: Existing recessed lighting fixtures require repeated calibration of the alignment between the housing 2 and the base 1 during installation, especially since the operator needs to stand at a height for installation, resulting in poor visibility and time-consuming assembly. In this invention, the bottom of the inner wall of the base 1 adopts an inclined surface design with a larger bottom and a smaller top. When the housing 2 is inserted, it can be automatically guided and aligned along the inclined surface without the need for additional tools for calibration, enabling quick installation and reducing the risk of jamming during embedded installation.

[0053] Advantage 2: Existing lighting fixtures typically use several bolts to fix the housing 2 to the base 1. Disassembling and installing these bolts during high-altitude operations is time-consuming and carries a risk of bolts falling. This invention uses a connecting piece 26 composed of a vertical rod 261, a connecting rod 262, a locking plate 263, a spring 265, and a ring plate 264. Simply pulling down the vertical rod 261 retracts the locking plate 263, separating the housing 2 from the base 1. After releasing the vertical rod 261, the spring 265 automatically resets, driving the locking plate 263 into the slot 11. The entire disassembly and assembly process is quicker and more efficient than existing bolt-fixing methods. Furthermore, it eliminates the need for specialized tools, reducing the difficulty and safety hazards of high-altitude operations.

[0054] Thirdly, the outer surface of the card plate 263 away from the vertical rod 261 adopts an arc design, and in the unfolded state, the outer surface of the card plate 263 protrudes from the circumferential outer surface of the housing 2. The outer surface of the card plate 263 away from the vertical rod 261 is provided with a rubber strip that fits against the inner wall surface of the slot 11. When the card plate 263 is inserted into the slot 11, the rubber strip is squeezed and undergoes slight deformation, which enhances the tightness and stability of the connection between the card plate 263 and the slot 11, and prevents the lamp from becoming loose during use.

[0055] Fourthly, most existing lighting fixtures are rigidly fixed to the wall or ceiling. When there is a level deviation in the wall or ceiling, the base 1, housing 2, and substrate 3 will tilt accordingly, causing light spot shift, uneven illuminance, and creating blind spots. In this invention, the ball head 23 and the spherical arc plate 31 in the middle of the substrate 3 are concentric. In the adjusting component 32, by moving the toggle block 326, the slider 327 and the arc-shaped rack 328 move, which in turn drives the gear 323 to rotate, causing the threaded rod 325 to move up and down. Through the ball groove seat 321, a pushing or pulling force is applied to the substrate 3, causing the substrate 3 to rotate around a specific connecting line as the axis of rotation. This can accurately counteract the tilt deviation of the wall or ceiling, restoring the substrate 3 to a level state. After adjustment, the light from the energy-saving fluorescent lamp can shine vertically downwards, providing uniform illumination and eliminating the lighting problems caused by wall or ceiling deviation. At the same time, the adjusting component 32 is located inside the housing 2, and adjustment can be completed by directly moving the toggle block 326, resulting in a simple and beautiful appearance.

[0056] Advantage 5: The two ball groove seats 321 distributed at 90 degrees and the matching adjustment parts 32 enable the substrate 3 to rotate in multiple dimensions around different axes. This can handle different angular deviations such as left-high-right-low, left-low-right-high, front-high-back-low, front-low-back-high, and left-front-high, right-rear-low. The adjustment angle range is wide and can accurately compensate for the tilt error of the ceiling in any direction (front-back, left-right, or combined directions). After adjustment, the substrate 3 is corrected to a horizontal state, ensuring that the light-emitting surface always remains horizontal and the light is projected vertically downward, thereby ensuring the uniformity and standardization of the lighting area and improving the final lighting quality.
