Technical Field
[0001] This utility model relates to the field of lawn light technology, and in particular to a retractable lawn light. Background Technology
[0002] Lawn lights, also known as patio lights or garden lights, are specifically designed for installation on lawns, garden paths, landscaped perimeters, or in courtyards. Their primary purposes are to create ambiance, beautify the landscape, guide pathways, and provide safety warnings. Current lawn lights typically use only a single light source. To illuminate the entire circumference, they require increased light source power or complex optical diffusion structures. This often results in an overly bright central area and dim surrounding areas, leading to uneven light distribution. Furthermore, existing lawn lights are usually installed at a fixed height, making it impossible to flexibly adjust them to meet the lighting needs of different scenarios. Utility Model Content
[0003] The purpose of this invention is to propose a retractable lawn light to solve the problems of uneven light output and non-adjustable illumination height in existing lawn lights.
[0004] To achieve this objective, the present invention adopts the following technical solution: A retractable lawn light includes a telescopic pole assembly, a mounting base, an optical assembly, and a lampshade; the mounting base is installed at one end of the telescopic pole assembly, which is retractable in a vertical direction. The optical component includes a circuit board, a light source, and a reflector. The circuit board is fixed to the mounting base. The light sources are arranged in a circular pattern on the top of the circuit board. The reflectors correspond one-to-one with the light sources and are also arranged in a circular pattern on the top of the circuit board. The lampshade is fixed to the top of the mounting base, and the optical components are housed in the inner cavity of the lampshade. A light-emitting plate is provided at the bottom of the lampshade.
[0005] To further explain, the telescopic pole assembly includes a base, a fixed pole, a pole sleeve, a movable pole, and a telescopic fixing component; The fixing rod is disposed on the top of the base. The inner wall of the top of the fixing rod is provided with an internal thread, and the outer wall of the bottom of the rod sleeve is provided with an external thread. The rod sleeve is fixed to the inner thread of the top of the fixing rod through the external thread of its outer wall. The movable rod is sleeved in the inner cavity of the fixed rod and the sleeve, and can extend and retract vertically; The side wall of the rod sleeve is provided with a telescopic fixing hole, and the telescopic fixing member is disposed in the telescopic fixing hole for fixing the movable rod to the rod sleeve.
[0006] To further explain, the bottom outer wall of the movable rod is provided with a limiting step. When the movable rod rises to its position, the top surface of the limiting step abuts against the bottom surface of the rod sleeve.
[0007] To further explain, the bottom inner wall of the mounting base is provided with an internal thread, and the top outer wall of the movable rod is provided with an external thread. The mounting base is fixed to the external thread of the top outer wall of the movable rod through the internal thread of its bottom inner wall.
[0008] To further explain, the mounting base has a power driver mounting cavity inside, the side wall of the power driver mounting cavity has a first cable outlet hole, and the bottom of the power driver mounting cavity has a second cable outlet hole; The first wire outlet is connected to the inner cavity of the lampshade, and the second wire outlet is connected to the inner cavity of the fixed rod, the rod sleeve, and the movable rod.
[0009] To further explain, the top outer wall of the mounting base is provided with an external thread, and the inner top of the lampshade is provided with an internal thread, which is used to fix the lampshade to the external thread on the top outer wall of the mounting base.
[0010] To further explain, the reflector includes a reflector cup and a fixing part, wherein the fixing part is integrally formed on one side of the bottom of the reflector cup; The fixing part is provided with a fixing hole, and a fixing member is provided in the fixing hole. The fixing part is fixed to the top of the circuit board by the fixing member.
[0011] To further explain, the bottom inner ring of the lampshade is provided with a first glue groove, the outer wall of the mounting base is provided with a second glue groove, and the light-emitting plate is annular; The first and second glue tanks are filled with glue to fix the light-emitting plate to the bottom of the lampshade.
[0012] The technical solution provided by this utility model can include the following beneficial effects: When in use, the vertical height of the lawn light can be adjusted via the telescopic rod assembly to suit different usage scenarios.
[0013] The circuit board is annular in shape, with the light sources distributed in equal-spaced circles on the top of the circuit board. Each reflector corresponds to one of the light sources and is also distributed in equal-spaced circles on the top of the circuit board, thus constructing multiple independent optical units evenly distributed around the circumference. Each unit illuminates a sector, structurally ensuring uniform light distribution in a 360-degree direction, achieving circumferential light uniformity. The light reflected by the reflectors illuminates the corresponding application area from the light-emitting plate at the bottom of the lampshade. After passing through the light-emitting plate, the light becomes evenly soft and uniform, without glaring spots, significantly improving lighting quality and visual comfort. The lampshade isolates the optical components from the outside environment, providing dust and water protection.
[0014] With the above configuration, the distributed light source disperses the heat points on the circumference, making it difficult for heat to accumulate. Furthermore, the circuit board is directly fixed to the mounting base, which facilitates faster heat conduction and dissipation through the mounting base and telescopic rod assembly. This effectively reduces the operating temperature of the light source, thereby extending its service life and maintaining stable light output. Attached Figure Description

Detailed Implementation
[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0018] like Figure 1-10 As shown, a retractable lawn light includes a telescopic pole assembly 1, a mounting base 2, an optical assembly 3, and a lampshade 4; The mounting base 2 is installed at one end of the telescopic rod assembly 1, and the telescopic rod assembly 1 can extend and retract in the vertical direction; The optical component 3 includes a circuit board 31, a light source 32, and a reflector 33. The circuit board 31 is fixed to the mounting base 2. The light sources 32 are arranged in a circular pattern on the top of the circuit board 31. The reflectors 33 correspond one-to-one with the light sources 32 and are arranged in a circular pattern on the top of the circuit board 31. The lampshade 4 is fixed to the top of the mounting base 2 and the optical component 3 is housed in the inner cavity of the lampshade 4. The bottom of the lampshade 4 is provided with a light-emitting plate 41.
[0019] When in use, the vertical height of the lawn light can be adjusted via the telescopic rod assembly 1 to suit different usage scenarios.
[0020] In this embodiment, the circuit board 31 is annular. The light sources 32 are distributed circumferentially at equal intervals on the top of the circuit board 31. The reflectors 33 correspond one-to-one with the light sources 32 and are also distributed circumferentially at equal intervals on the top of the circuit board 31, thus constructing multiple independent optical units evenly distributed around the circumference. Each unit is responsible for illuminating a sector, which structurally ensures the uniform distribution of light emitted from the light sources 32 in a 360-degree direction, thereby achieving circumferential light uniformity. Finally, the light reflected by the reflectors 33 shines from the light-emitting plate 41 at the bottom of the lampshade 4 onto the corresponding application scene. After passing through the light-emitting plate 41, the light becomes evenly softer and more uniform, without glaring spots, significantly improving the lighting quality and visual comfort. The lampshade 4 isolates the optical components 3 from the outside world, providing dust and water protection.
[0021] With the above configuration, the distributed light source 32 disperses the heat points on the circumference, making it difficult for heat to accumulate. Furthermore, the circuit board 31 is directly fixed to the outer periphery of the mounting base 2, which facilitates the faster conduction and dissipation of heat through the mounting base and telescopic rod assembly 1. This effectively reduces the operating temperature of the light source, thereby extending the service life of the light source 32 and maintaining stable light output. In this embodiment, the light source 32 is an LED light source.
[0022] The circuit board 31 is specifically fixed to the mounting plane on the outer periphery of the mounting base 2 by fasteners 311. The mounting plane is an annular platform. In this embodiment, the fastener is a screw. The fastener 311 is screwed into the mounting plane 2001 from the bottom of the circuit board 31. Both the mounting plane 2001 and the circuit board 31 have screw holes that cooperate with the fastener 311.
[0023] To further explain, the telescopic rod assembly 1 includes a base 11, a fixed rod 12, a rod sleeve 13, a movable rod 14, and a telescopic fixing member 15; The fixing rod 12 is disposed on the top of the base 11. The inner wall of the top of the fixing rod 12 is provided with an internal thread, and the outer wall of the bottom of the rod sleeve 13 is provided with an external thread. The rod sleeve 13 is fixed to the inner thread of the top of the fixing rod 12 by the external thread of its bottom outer wall. The movable rod 14 is sleeved in the inner cavity of the fixed rod 12 and the rod sleeve 13, and can extend and retract vertically; The side wall of the sleeve 13 is provided with a telescopic fixing hole 131, and the telescopic fixing member 15 is disposed in the telescopic fixing hole 131 for fixing the movable rod 14 to the sleeve 13.
[0024] The fixing rod 12 and the sleeve 13 are fixed together by internal and external threads. This connection method has high mechanical strength and strong resistance to torsion and lateral forces, ensuring that the supporting structure of the lamp body is firm and stable after the height is adjusted, and will not shake or loosen due to wind or slight impact.
[0025] The movable rod 14 extends and retracts independently within the cavities of the fixed rod 12 and the sleeve 13, and is locked in place by an independent telescopic fixing member 15 at the telescopic fixing hole 131 on the side wall of the sleeve 13. In this embodiment, the telescopic fixing member 15 is a knurled screw, and the telescopic fixing hole 131 is a screw hole. The knurled screw facilitates manual operation. This design makes height adjustment simple; the movable rod 14 can be slid up and down by loosening the telescopic fixing member 15, and locked by tightening the telescopic fixing member 15 after reaching the desired position. The adjustment process can be completed without complicated tools, making the operation simple and convenient. In this embodiment, the base 11 is a flange, providing a stable installation foundation for the lawn light and enhancing its resistance to tipping after installation.
[0026] To further explain, the bottom outer wall of the movable rod 14 is provided with a limiting step 141. When the movable rod 14 rises to the position, the top surface of the limiting step 141 abuts against the bottom surface of the rod sleeve 13.
[0027] When the movable rod 14 rises, the top surface of the limiting step 141 abuts against the bottom surface of the rod sleeve 13, forming a rigid physical stop. This provides the user with clear and definite "highest point" feedback, effectively preventing the movable rod from being completely pulled out of the rod sleeve or fixed rod due to excessive force or unclear stroke. In addition, this design avoids damage to the internal cable due to excessive pulling. The internal cable is not shown in the figure; the cable is existing technology and will not be described in detail here.
[0028] To further explain, the bottom inner wall of the mounting base 2 is provided with an internal thread, and the top outer wall of the movable rod 14 is provided with an external thread. The mounting base 2 is fixed to the external thread of the top outer wall of the movable rod 14 through the internal thread of its bottom inner wall.
[0029] The threaded connection between the mounting base 2 and the movable rod 14 forms a reliable and detachable rigid interface. This design allows the entire lighting head, including the optical component 3 and the lampshade 4, to be used as an independent module and to be quickly separated or combined with the telescopic rod assembly 1. This facilitates modular, separable rigid connection and makes installation and maintenance easier.
[0030] To further explain, the mounting base 2 has a power driver mounting cavity 21 inside, the side wall of the power driver mounting cavity 21 has a first cable outlet hole 211, and the bottom of the power driver mounting cavity 21 has a second cable outlet hole 212. The first wire outlet 211 is connected to the inner cavity of the lamp cover 4, and the second wire outlet 212 is connected to the inner cavities of the fixed rod 12, the rod sleeve 13, and the movable rod 14.
[0031] In this embodiment, a power driver is installed in the power driver mounting cavity 21. The power driver converts mains power into low-voltage DC power required for the LED light source. The low-voltage DC power is supplied to the light source 32 through the circuit board 31 to make it emit light. The second cable outlet 212 is responsible for connecting the incoming line from the telescopic rod assembly 1 (the mains power line introduced from the base 11), and the first cable outlet 211 is responsible for connecting the output end of the power driver to the cable of the circuit board 31 inside the lampshade 4. The power driver, the connection between the mains power line and the power driver, and the cable connection between the power driver and the circuit board 31 are all prior art, and therefore are not shown in the figures or described in detail herein.
[0032] The above design confines the heat and electromagnetic interference generated during the operation of the power driver to the independent power driver mounting cavity 21, reducing thermal shock and electrical interference to the precision optical components 3, especially the light source 32 and the circuit board 31, thereby improving the stability of the entire lamp operation and the lifespan of the light source.
[0033] To further explain, the top outer wall of the mounting base 2 is provided with an external thread, and the inner top of the lampshade 4 is provided with an internal thread, which is used to fix it to the external thread on the top outer wall of the mounting base 2.
[0034] This threaded connection method is achieved directly by the structure of the mounting base 2 and the lampshade 4 themselves, without the need for additional connecting parts, making the overall structure simpler and improving the convenience of assembly.
[0035] To further explain, the reflector 33 includes a reflector cup 331 and a fixing part 332, wherein the fixing part 332 is integrally formed on one side of the bottom of the reflector cup 331; The fixing part 332 is provided with a fixing hole, and a fixing member 333 is provided in the fixing hole. The fixing part 332 is fixed to the top of the circuit board 31 by the fixing member 333.
[0036] The fixing part 332 provides an independent mounting point for each reflector 331, which ensures that each reflector 331 can be accurately positioned and locked in a preset position on the circuit board 31, effectively preventing it from shifting, loosening or falling off due to vibration during transportation, installation or use. In this embodiment, the fixing hole is a screw hole and the fixing member 333 is a screw.
[0037] In this embodiment, the reflector cup 331, through its specific curved shape, can efficiently capture and redirect most of the light emitted by the light source 32 in various directions. This avoids the loss of light in useless directions (such as upwards or into the lamp), significantly improves the utilization efficiency of light energy, and achieves higher lighting brightness with less energy consumption.
[0038] To further explain, the bottom inner ring of the lampshade 4 is provided with a first glue groove 401, the outer wall of the mounting base 2 is provided with a second glue groove 201, and the light-emitting plate 41 is annular; The first glue tank 401 and the second glue tank 201 are filled with glue to fix the light-emitting plate 41 to the bottom of the lampshade 4.
[0039] The light-emitting plate 41 is annular, ensuring that it can pass smoothly through the outer wall of the mounting base 2. By setting a first glue groove 401 on the inner ring of the bottom of the lampshade 4 and a second glue groove 201 on the outer wall of the mounting base 2, two clear and continuous glue storage and bonding interfaces are provided for the glue. This dual-groove design allows the glue to not only bond the light-emitting plate 41 to the lampshade after curing, but also form a second layer of bonding and support through the side wall of the mounting base 2. This greatly increases the bonding area and bonding strength, while forming a double sealing barrier, which greatly improves the waterproof and dustproof level.
[0040] In this embodiment, the light-emitting plate 41 is a glass plate, and it is also provided with a circular light-emitting area 411. After the power supply 32 emits light, the light reflected by the reflector 33 is emitted through the light-emitting area 411. The remaining area of the light-emitting plate 41 is treated with a screen printing process to have a light-shielding effect, thereby ensuring that light can be emitted from the specific light-emitting area 411. That is, the light-emitting plate 41 is a whole circular glass plate, and the light-emitting area 411 is the transparent part of the glass plate that is not screen printed.
