Description

Technical Field

[0001] This invention belongs to the field of energy-saving lighting technology, and specifically relates to an outdoor LED energy-saving lighting lamp. Background Technology

[0002] LED energy-saving lamps, with their advantages of high luminous efficiency, long lifespan, and low energy consumption, have been widely used in various outdoor locations, such as residential courtyards, industrial parks, agricultural greenhouses, ecological farms, holiday camps, and private landscape areas. To improve the maintainability of the lamps and achieve precise light projection and focused illumination, some existing technologies attempt to introduce lifting and angle adjustment functions. For example, Chinese utility model patent CN213040501U discloses an "environmentally friendly lighting lamp" that uses a worm gear to drive a screw to lift the lamp body and uses a wire rope winding mechanism to adjust the illumination angle of the LED lamp holder, aiming to reduce the difficulty of high-altitude maintenance. However, this structure has revealed a series of problems in practical applications: First, in order to accommodate the movement of the transmission components, multiple longitudinal grooves (such as the first groove and the second groove) and through grooves need to be opened on the pole, which seriously damages the sealing integrity of the lamp body, making it easy for rainwater, dust, insects and other things to enter the interior. This not only accelerates the corrosion and jamming of mechanical parts, but may also cause electrical faults, making it difficult to meet the basic requirements of high protection level in outdoor environments. Secondly, the angle adjustment system using wire rope traction and multi-link limiting has a complex structure with numerous parts and requires high assembly precision. It is prone to loosening and failure under long-term exposure to wind, sun, or vibration, leading to a shift in the lighting angle and affecting the actual lighting effect. Furthermore, this solution relies on purely manual operation (such as rotating a knob or handle). Even after the light fixture is raised to a higher position, users still need a ladder or climbing tools to reach the angle adjustment mechanism, failing to truly achieve convenient and safe ground-level maintenance. Finally, LED lighting components are exposed to the external environment for a long time without effective physical protection. They cannot be retrieved during non-use periods or in severe weather, which not only causes light pollution but also accelerates the aging of optical components and poses a risk of theft or human damage. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an outdoor LED energy-saving lighting lamp to solve the problems existing in the background art.

[0004] To address the aforementioned technical problems, the present invention provides an outdoor LED energy-saving lighting fixture, comprising a lamp holder. A linear control component is installed within the lamp holder. The linear control component has a height-adjustable movable part, on which a mounting plate is oscillating. The mounting plate is used to mount an LED lighting component. By oscillating the mounting plate on the movable part, the illumination angle of the LED lighting component can be adjusted, achieving precise light projection and concentrated illumination. Simultaneously, the LED lighting component can be adjusted to a vertical position, allowing it to retract entirely into the lamp holder. After retraction, the linear control component drives the LED lighting component to rise and fall, facilitating low-altitude maintenance of the LED lighting component.

[0005] Preferably, the movable component has a swing fulcrum connected to the mounting plate, and a drive motor is provided on the swing fulcrum of the movable component to control the swing of the LED lighting component; the linear control component adopts a ball screw structure, and the movable component is a nut seat on the ball screw.

[0006] Preferably, the movable component has a swing fulcrum connected to the mounting plate, and a transmission gear is rotatably mounted on the movable component at the swing fulcrum. The transmission gear is fixedly connected to the mounting plate. By driving the transmission gear to rotate, the mounting plate is driven to rotate around the swing fulcrum, thereby achieving adjustment of the irradiation angle.

[0007] Furthermore, the linear control component adopts a gear and rack structure, which includes a fixed rack and a movable gear. The fixed rack is vertically fixed inside the lamp, and the movable gear is movably mounted on the moving part. When the movable gear and the fixed rack mesh, the movable rack is driven to rotate, and the lifting and lowering adjustment of the moving part is realized under the cooperation of the movable gear and the fixed rack.

[0008] Furthermore, the movable component is equipped with a control seat capable of moving laterally between the fixed rack and the transmission gear. The movable gear is rotatably mounted on the control seat, and a movable motor for driving the movable gear to rotate is mounted on the rotating seat. By driving the control seat to move between the fixed rack and the transmission gear, the movable gear selectively engages with either the fixed rack or the transmission gear. When the movable gear engages with the fixed rack, driving the movable gear to rotate causes the movable component to rise and fall vertically, achieving height adjustment. When the movable gear engages with the transmission gear, driving the movable gear to rotate causes the transmission gear to rotate, thereby driving the mounting plate fixedly connected to it to swing, achieving adjustment of the illumination angle of the LED lighting component. Thus, by switching the engaging objects, independent control of the rising and falling and angle adjustment functions can be achieved.

[0009] Furthermore, the control base is equipped with a linear moving component for driving it to move along a preset direction on the moving component, so as to switch the meshing state of the moving gear with the fixed rack or transmission gear.

[0010] Furthermore, the lamp holder has an illumination adjustment area at the top and a maintenance area at the bottom; the linear moving component is fixedly installed within the illumination adjustment area inside the lamp holder, and the linear moving component and the fixed rack are installed on the same side of the inner wall of the lamp holder. The driving direction of the linear moving component is the same as the orientation of the sawtooth surface of the fixed rack. Fixing the linear moving component to the lamp holder not only enables the control seat to move laterally when the LED lighting component is in the illumination adjustment area, realizing the meshing switching of the moving gear between the fixed rack and the transmission gear, and meeting the independent control requirements of lifting adjustment and illumination angle adjustment; it also effectively reduces the overall weight of the moving component by integrating the drive mechanism into the lamp holder instead of the moving component, which is beneficial to improving the smoothness and energy efficiency of the lifting movement.

[0011] Furthermore, the movable component is provided with a clamping member, which is used to clamp and fix the movable component between the fixed rack or transmission gear. The clamping member includes a clamping block and a control block slidably disposed on the movable component, and a piston chamber opened in the movable component. A first piston and a second piston are respectively disposed at both ends of the piston chamber. The first piston is connected to the clamping block, and the second piston is connected to the control block. The clamping surface of the clamping block is parallel to the end face of the transmission gear and the fixed rack. The control block is located on the moving path of the control seat. When switching the meshing state of the movable gear with the fixed rack or transmission gear, the control seat pushes the control block during the movement, causing the second piston to move within the piston chamber. Pressure is transmitted through the medium within the piston chamber, driving the first piston to move synchronously, thereby causing the clamping block to clamp or release the fixed rack or transmission gear, realizing reliable locking or unlocking of the movable component at the target position.

[0012] Furthermore, the fixed rack and the transmission gear are each equipped with independent clamping components; wherein, the clamping component for controlling the clamping state of the fixed rack is a rack control component, and the clamping component for controlling the clamping state of the transmission gear is a gear control component; the control block of the rack control component is located near the fixed rack, and the control block of the gear control component is located near the fixed rack, so that the corresponding clamping components are triggered to perform actions during the movement of the control seat, thereby realizing independent clamping and release of the fixed rack or the transmission gear.

[0013] Furthermore, when the moving direction of the control block and the moving direction of the control seat are not parallel, the control block is provided with an inclined surface that contacts the control seat; when the control seat moves and acts on the inclined surface, it drives the control block to generate displacement along a predetermined direction, thereby realizing the conversion of the movement direction and the transmission of force.

[0014] The main technical effects of this invention are reflected in the following aspects: This invention abandons the traditional design of grooves on the pole, adopting a fully enclosed cylindrical lamp holder without any through openings, and featuring a swing cover with a return torsion spring in the top lighting adjustment area. Under normal conditions, the cover automatically closes, ensuring the entire lamp is completely sealed; when the LED lighting components swing outwards, their front end actively pushes open the cover, opening the lighting window. This design dynamically decouples "protection" from "function," effectively preventing rainwater, dust, insects, and ultraviolet rays from entering when not in use, avoiding the long-term aging and pollution problems caused by constantly open windows.

[0015] This invention introduces a laterally movable control seat, allowing the same moving gear to selectively mesh with a fixed rack (for lifting) or a transmission gear (for angle adjustment). By switching the position of the control seat, only one moving motor can drive the lifting motion or angle swing separately, completely eliminating the complex mechanisms such as wire ropes, worm gears, and multi-link limiters in traditional solutions. This meshing switching mechanism not only significantly reduces the number of parts but also lowers the assembly difficulty.

[0016] By rotating the mounting plate around the pivot point to a vertical position, the LED lighting components can be completely retracted into the lamp holder cavity, achieving physical concealment. This function not only completely eliminates light pollution during non-use periods but also provides active protection in severe weather conditions such as typhoons, hail, and sandstorms, extending the lifespan of optical components; it also effectively prevents theft and vandalism; furthermore, by retracting the LED lighting components entirely into the lamp holder cavity, the need for grooves on the lamp holder found in traditional lifting structures is eliminated.

[0017] This invention features two independent clamping components on the moving part, used to lock the lifting position (clamping the fixed rack) and the angle adjustment position (clamping the transmission gear), respectively. Each clamping component includes a clamping block and a control block connected by a piston chamber. Movement of the control seat triggers the displacement of the control block, and the pressure of the medium within the chamber synchronously drives the clamping block to press against the end face of the target part. This mechanism requires no additional motor or electromagnetic lock, achieving high-rigidity self-locking solely through mechanical linkage. It is energy-efficient and reliable, and particularly suitable for precise positioning requirements under frequently changing operating conditions.

[0018] The linear moving component is integrated into the lamp holder body, rather than moving with the lamp holder itself. This significantly reduces the load mass of the moving component, which not only reduces the driving torque and energy consumption required for lifting, but also improves the smoothness and response speed of the movement. At the same time, it is beneficial for motor heat dissipation and cable management, extends the service life of core components, and meets the overall optimization goal of energy-saving lighting systems.

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. In the embodiments, it should be understood that the terms "middle," "upper," "lower," "top," "right side," "left end," "above," "back," "center," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, unless otherwise specified in this specific embodiment, the connection or fixing method between components can be achieved by bolt fixing, pin fixing, or pin connection commonly used in the prior art, etc., and therefore will not be described in detail in this embodiment.

[0021] The outdoor LED energy-saving lighting provided by this invention is mainly used in the field of outdoor LED energy-saving lighting, but it should not be limited thereto. It can also be applied to other lighting equipment or mechatronic devices with the same or similar functional requirements.

[0022] Furthermore, as is common knowledge in this industry, the ball screw structure, gear and rack transmission mechanism, electric push rod, return torsion spring, and piston chamber linkage principle mentioned above are all conventional technical means in the field of mechanical transmission and automatic control. Given that their structure and working principle are well known to those skilled in the art, they will not be elaborated upon here.

[0023] Example 1 This embodiment provides an outdoor LED energy-saving lighting lamp, aiming to solve the core problems of existing technologies such as poor sealing, complex structure, inconvenient maintenance, and long-term exposure of the lamp. See also Figure 1 , Figure 2 The system includes a lamp holder 1, which is a fully enclosed cylindrical structure with no longitudinal or transverse through openings inside. It has an external window (for light transmission during lighting) only in the lighting adjustment area 11 at the top, and an openable inspection port in the maintenance area 12 at the bottom. This effectively solves the problem of rainwater and dust intrusion caused by the chute.

[0024] In addition, in some embodiments, the external window of the lighting adjustment area 11 can be optimized as follows: A cover plate is swaying on the external window. The cover plate is hinged to the lamp holder 1 via a pivot, and a return torsion spring is provided between the cover plate and the lamp holder 1. This allows the cover plate to automatically close when no external force is applied, maintaining the lighting adjustment area 11 in a completely closed state. When the mounting plate 22 swings upward on the moving part 21 to unfold the LED lighting component, the LED lighting component or the front end of the mounting plate 22 abuts against and pushes the cover plate, overcoming the elastic force of the return torsion spring and opening it, thereby opening the external window and realizing external lighting. When the LED lighting component is retracted into the lamp holder 1, the cover plate automatically returns to its original position under the action of the return torsion spring and seals the window, restoring the fully enclosed protective state.

[0025] Preferred, see Figure 2 , Figure 3The lamp holder 1 is equipped with a linear control component 2, which has a height-adjustable movable part 21. A mounting plate 22 is oscillating on the movable part 21, and the mounting plate 22 is used to mount the LED lighting component. By swinging the mounting plate 22 on the movable part 21, the illumination angle of the LED lighting component can be adjusted, achieving precise light projection and concentrated illumination. Furthermore, the LED lighting component can be adjusted to a vertical position and retracted entirely into the lamp holder 1. In the retracted state, it not only effectively prevents light pollution and slows down the aging of optical components, but also resists wind, rain, hail, vandalism, or theft, making it particularly suitable for ecologically sensitive areas, private courtyards, or unattended scenarios. After the LED lighting component is retracted, the linear control component 2 drives the LED lighting component to rise and fall, facilitating low-altitude maintenance. By retracting the entire LED lighting component into the inner cavity of the lamp holder 1, the need for a sliding groove on the lamp holder 1 in traditional lifting structures is avoided, achieving a fully enclosed design without openings, significantly enhancing dustproof, waterproof, and corrosion-resistant performance.

[0026] Furthermore, the linear control component 2 adopts a ball screw structure: the moving part 21 has a swing fulcrum connected to the mounting plate 22, and the moving part 21 is provided with a drive motor at the swing fulcrum, which controls the swing of the LED lighting component; the linear control component 2 adopts a ball screw structure, and the moving part 21 is a nut seat on the ball screw.

[0027] Preferred, see Figure 3 The linear control component 2 adopts a gear and rack structure: the moving part 21 has a swing fulcrum connected to the mounting plate 22, and a transmission gear 23 is rotatably mounted on the moving part 21 at the swing fulcrum. The transmission gear 23 is fixedly connected to the mounting plate 22. By driving the transmission gear 23 to rotate, the mounting plate 22 is driven to rotate around the swing fulcrum, thereby realizing the adjustment of the illumination angle. The linear control component 2 adopts a gear and rack structure, which includes a fixed rack 24 and a moving gear 25. The fixed rack 24 is vertically fixed inside the lamp, and the moving gear 25 is movably mounted on the moving part 21. When the moving gear 25 and the fixed rack 24 mesh, by driving the moving rack to rotate, the moving part 21 can be adjusted in height by the cooperation of the moving gear 25 and the fixed rack 24.

[0028] The key innovation regarding the gear and rack structure lies in: (See...) Figure 4 , Figure 5The movable component 21 is equipped with a control seat 26 that can move laterally between the fixed rack 24 and the transmission gear 23. The movable gear 25 is rotatably mounted on the control seat 26, and a movable motor for driving the movable gear 25 to rotate is mounted on the rotating seat. By driving the control seat 26 to move between the fixed rack 24 and the transmission gear 23, the movable gear 25 can selectively mesh with either the fixed rack 24 or the transmission gear 23. When the movable gear 25 meshes with the fixed rack 24, driving the movable gear 25 to rotate can cause the movable component 21 to rise and fall vertically, thereby achieving height adjustment. When the movable gear 25 meshes with the transmission gear 23, driving the movable gear 25 to rotate can cause the transmission gear 23 to rotate, thereby driving the mounting plate 22 fixedly connected to it to swing, thereby achieving adjustment of the illumination angle of the LED lighting component. Thus, by switching the meshing objects, independent control of the rising and falling and angle adjustment functions can be achieved. By controlling the lateral displacement of the control seat 26, the moving gear 25 can selectively mesh with the fixed rack 24 (for lifting) or the transmission gear 23 (for angle adjustment), thereby achieving physical decoupling and independent control of the lifting and angle adjustment functions; avoiding the complex transmission chains such as wire ropes and multi-links in traditional solutions, greatly simplifying the structure and improving reliability.

[0029] Regarding the gear and rack structure further, to ensure stable locking of the moving part 21 at the target height or angular position. See [link / reference]. Figure 6The moving part 21 is equipped with a clamping component 3, and the fixed rack 24 and the transmission gear 23 are each equipped with an independent clamping component 3. The clamping component 3 used to control the clamping state of the fixed rack 24 is a rack control component, used to clamp the fixed rack 24 to lock its lifting position; the clamping component 3 used to control the clamping state of the transmission gear 23 is a gear control component, used to clamp the transmission gear 23 to lock its angle adjustment position. This allows the corresponding clamping component 3 to be triggered during the movement of the control seat 26, achieving independent clamping and release of the fixed rack 24 or the transmission gear 23. The clamping component 3 includes a clamping block 31 and a control block 32 slidably disposed on the moving part 21, and a piston chamber formed within the moving part 21. A first piston and a second piston are respectively disposed at both ends of the piston chamber. The first piston is connected to the clamping block 31, and the second piston is connected to the control block 32. The clamping surface of the clamping block 31 is parallel to the end faces of the transmission gear 23 and the fixed rack 24. The control block 32 is located on the moving path of the control seat 26. When the control seat 26 moves to the corresponding position, it pushes the control block 32, and through the pressure transmission of the medium (air or hydraulic oil) in the piston chamber, synchronously drives the clamping block 31 to press against the end face of the fixed rack 24 or the transmission gear 23, achieving self-locking. The reverse action releases the clamping, allowing movement. No additional locking motor is required; reliable positioning is achieved through mechanical linkage, which is energy-saving and reliable. When switching the engagement state of the moving gear 25 with the fixed rack 24 or the transmission gear 23, the control seat 26 pushes the control block 32 during the movement, causing the second piston to move within the piston chamber. Pressure is transmitted through the medium within the piston chamber, driving the first piston to move synchronously, thereby causing the clamping block 31 to clamp or release the fixed rack 24 or the transmission gear 23, thus achieving reliable locking or unlocking of the moving part 21 at the target position.

[0030] Furthermore, in cases where the movement directions of the control seat 26 and the control block 32 are inconsistent (e.g., the control seat 26 moves horizontally, while the control block 32 needs to move vertically or obliquely), when the movement direction of the control block 32 is not parallel to the movement direction of the control seat 26, the control block 32 is provided with an inclined surface 33 that contacts the control seat 26; when the control seat 26 moves and acts on the inclined surface 33, it drives the control block 32 to generate displacement along a predetermined direction, thereby realizing the conversion of the movement direction and the transmission of force.

[0031] Finally, the control base 26 is equipped with a linear moving component (telescopic rod, telescopic cylinder) to drive it to move along a preset direction on the moving part 21, thereby switching the meshing state of the moving gear 25 with the fixed rack 24 or the transmission gear 23. The linear moving component is fixedly installed in the lighting adjustment area 11 inside the lamp holder 1. The linear moving component and the fixed rack 24 are installed on the same side of the inner wall of the lamp holder 1, and the driving direction of the linear moving component is the same as the orientation of the sawtooth surface of the fixed rack 24. Fixing the linear moving component to the lamp holder 1 not only enables the control base 26 to move laterally when the LED lighting component is in the lighting adjustment area 11, realizing the meshing switching of the moving gear 25 between the fixed rack 24 and the transmission gear 23, and meeting the independent control requirements of lifting adjustment and illumination angle adjustment; it also effectively reduces the overall weight of the moving part 21 by integrating the drive mechanism into the lamp holder 1 instead of the moving part 21, which is beneficial to improving the smoothness and energy efficiency of the lifting movement.

[0032] Example 2 This embodiment, based on the lighting lamp in Embodiment 1, details the complete operation process of the outdoor LED energy-saving lighting lamp in practical applications.

[0033] Regarding daily lighting and angle adjustment, firstly, the clamping state of the transmission gear 23 is released, and the control seat 26 remains engaged with the transmission gear 23; then, the moving motor rotates forward or reverse to drive the mounting plate 22 to rotate around the swing fulcrum to the target illumination angle (for example, from 30° to 45° to expand the lighting coverage); after the angle is in place, the corresponding clamping component 3 automatically re-locks the transmission gear 23 to ensure long-term stability of the illumination angle; during this process, the LED lighting component is always located outside the lamp holder 1, and the top cover remains open under its push to ensure normal light transmission.

[0034] Regarding the complete retraction of the lamp (applicable during non-use periods, in severe weather, or in protective mode), first release the clamping of the transmission gear 23; then, the moving motor reverses its drive, causing the mounting plate 22 to swing inward until the entire LED lighting component is in a vertically upward state; at this time, the LED lighting component is completely retracted into the inner cavity of the lamp holder 1; the top cover automatically closes under the action of the reset torsion spring, achieving a fully enclosed seal of the lighting adjustment area 11, effectively isolating rainwater, dust, and external interference.

[0035] Regarding low-altitude maintenance (when LED lighting components malfunction or require regular cleaning), first, retract the LED lighting components to a vertical position; then, the control base 26 moves laterally, switching to a position engaged with the fixed rack 24; subsequently, the moving motor drives the moving gear 25 to rotate, and with the cooperation of the fixed rack 24, the entire moving component 21 is smoothly lowered along the inner wall of the lamp holder 1 to the bottom maintenance area 12 (approximately 0.8–1.2 meters from the ground); after the moving component 21 reaches the maintenance position, the clamping component 3 automatically locks the fixed rack 24 to prevent accidental slippage; the user can open the inspection port at the bottom of the lamp holder 1 to directly replace, clean, or test the LED module, driver power supply, or optical lens; after maintenance is completed, close the inspection port.

[0036] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
