Description

Technical Field

[0001] This application belongs to the field of lighting device technology, and more specifically, relates to an adjustable pool light. Background Technology

[0002] In recent years, lighting technology has been constantly iterating, and the function of lamps has extended from basic light supply to scenario-based and personalized needs. Specialized lighting fixtures for different places such as swimming pools, indoor venues, and landscape decorations have emerged. Among them, swimming pool scenarios, due to high humidity, easy water accumulation, and the special spatial environment, have put forward higher requirements for the uniformity of lighting, the flexibility of illumination range, and scene adaptability of lamps. In particular, the demand for overhead lighting is becoming increasingly prominent. High-quality overhead lighting can avoid glare caused by direct light shining into swimmers' eyes, while also improving the overall lighting quality of the pool area.

[0003] Currently, commonly used lighting fixtures in swimming pool settings mainly fall into two categories: traditional chandeliers and direct-beam pool lights. Traditional chandeliers are mostly fixed installations, resulting in a fixed lighting range and uneven light intensity distribution. Areas near the light fixture are often overly illuminated, while edge areas are underlit. They are highly dependent on the fixture's distribution design and struggle to flexibly adapt to the overall overhead lighting needs of different pools. Direct-beam pool lights, on the other hand, primarily focus on lateral direct illumination of the pool walls and water surface. However, direct light projection onto the water surface can cause strong reflections, affecting lighting comfort and resulting in a limited illumination area and an inability to achieve uniform overhead lighting. In summary, existing pool lighting fixtures generally suffer from poor lighting uniformity and fixed, unadjustable illumination areas, making it difficult to meet the needs of swimming pools and similar venues for uniform overhead lighting and flexible adjustment of the illumination range. Summary of the Invention

[0009] The sealing plate passes through the inner ring through hole onto the extension rod; the outer ring of the sealing plate rests on the bottom of the ceiling box cavity; when the extension rod swings, it causes the sealing plate to slide at the bottom of the ceiling box cavity. A gap is left between the inner ring of the sealing plate and the outer wall of the extension rod; the outer ring size of the sealing plate is larger than the inner diameter of the clearance hole but smaller than the inner diameter of the ceiling box.

[0010] In one design, the sealing plate is composed of a first clamping piece and a second clamping piece.

[0011] The inner ring through holes of the first clamping plate and the second clamping plate are both elliptical; the second clamping plate is fixedly stacked on the first clamping plate, and the inner ring major axis of the first clamping plate is perpendicular to the inner ring major axis of the second clamping plate in the vertical direction.

[0012] The first clamping plate has a set of mounting slots on both sides with a symmetrical structure; the second clamping plate is composed of two symmetrical structural pieces joined together from the left and right, and the two structural pieces are fixed in the mounting slots from both sides.

[0013] In one design, the top edge of the ceiling box has a set of symmetrical U-shaped slots facing downwards, and the bottom edge of the mounting plate has a set of corresponding feet facing downwards; when the ceiling box and the mounting plate are assembled, the feet are engaged in the U-shaped slots.

[0014] In one embodiment, the lamp body includes an arc-shaped lampshade and structural side plates mounted at both ends of the lampshade. The lamp body is fixedly connected to the power supply box by mounting connecting plates on the outer sides of each structural side plate; the structural side plates and connecting plates are connected by a central pivot or several arc-shaped holes, allowing the lamp body to rotate around the central pivot or the arc-shaped holes.

[0015] In one design, the lampshade is composed of a decorative panel and a heat sink; the light-emitting part is placed on the heat sink, and the reflective part is placed on the decorative panel.

[0016] In one embodiment, the decorative panel has at least one support rib extending along its length; the support rib has a through-channel, and both ends of the through-channel are machined with internal threads.

Furthermore, thanks to its excellent adjustability, this application can be extended to other overhead lighting scenarios such as stadiums. The overall structure is simple, reliable, and cost-effective, facilitating mass production and widespread application. Attached Figure Description

[0027] To address the issues of poor lighting uniformity and insufficient adaptability to different venues in existing swimming pool lighting fixtures, this application provides an adjustable swimming pool light, the specific embodiment of which is as follows: In one embodiment, please refer to Figure 1 and Figure 2 An adjustable pool light includes a lamp holder 1, an extension rod 2, a power supply box 3, and a lamp body 4.

[0028] In this embodiment, the top of the lamp holder 1 has a mounting plate 11 for assembly and fixation, and the top surface of the mounting plate 11 is the assembly surface. Assembly holes are provided on the mounting plate 11 to achieve top-mounted assembly of the lamp. Specifically, the assembly holes on the mounting plate 11 can be configured as several arc-shaped holes distributed on the same circumference. By allowing fasteners to move within these arc-shaped holes, the lamp as a whole has a certain degree of rotational adjustment capability. A hinge seat 12 with a locking mechanism is fixedly connected to the bottom of the mounting plate 11; one end of the extension rod 2 is hinged to the lamp holder 1 via the hinge seat 12, and the extension rod 2 can be adjusted by swinging around the hinge point. For example, the hinge seat 12 and the extension rod 2 are assembled and connected through two sets of mounting holes distributed vertically. One set of mounting holes is a symmetrically arranged circular through hole, which serves as the hinge point; the other set of through holes is a symmetrically arranged arc-shaped waist hole, which limits the swing range of the extension rod 2 and can be fixed after the extension rod 2 swings by locking fasteners; furthermore, ratchet, spring buckle and other mechanisms can also be used to lock the hinge seat 12.

[0029] In this embodiment, the power supply box 3 is fixedly connected to the other end of the extension rod 2 in the horizontal direction. Specifically, the power supply box 3 can be assembled and fixed with the extension rod 2 through an intermediate connecting component.

[0030] In this embodiment, the lamp body 4 is located on the side of the power supply box 3 away from the extension rod 2 and is fixedly connected to the power supply box 3. The lamp body 4 is a groove with an upward opening. The components and structures inside its cavity can be divided into a light-emitting part 43 integrated on one side and a reflective part located on the symmetrical side of the light-emitting part 43. The light-emitting part 43 is a light source device arranged at an angle, such as a light strip, a light tube, or an LED light strip. The reflective part is a smooth curved surface. The light emitted from the light-emitting part 43 is partially projected directly onto the top of the venue, and part of the light is reflected by the reflective part to areas at different angles, thereby achieving uniform lighting over a larger area.

[0031] Therefore, this application optimizes the structure and light source layout of the luminaire, combining adjustment and reflection in a coordinated structural design. On the one hand, it allows the upward-projected top light to be evenly diffused after reflection, effectively avoiding glare and uneven lighting, and significantly improving the lighting comfort of the pool area. On the other hand, the adjustment mechanism allows for flexible adjustment of the lighting angle and area, adapting to the lighting needs of different pool sizes and usage scenarios, thus solving the problem of fixed illumination areas in existing pool luminaires. Furthermore, thanks to its excellent adjustability, this application can be extended to other top lighting scenarios such as stadiums, and its overall structure is simple, reliable, and cost-effective, facilitating mass production and widespread application.

[0032] In one embodiment, please refer to Figures 1 to 3 Based on the aforementioned embodiments, the lamp holder 1 further includes a ceiling box 13. The ceiling box 13 is fixedly connected to the mounting plate 11 from below, housing the hinge seat 12 and part of the extension rod 2 within its inner cavity, thereby protecting and decorating the assembled components. The bottom of the ceiling box 13 has a clearance hole 132 for the extension rod 2 to pass through. The inner diameter of the clearance hole 132 is designed according to the swing amount of the extension rod 2. When the extension rod 2 swings around the hinge point to a preset limit position, it abuts against the edge of the clearance hole 132. For example, the edge of the mounting plate 11 can be constructed with several mounting lugs having mounting holes. The side wall of the ceiling box 13 has bolt holes corresponding to each mounting lug. After inserting each mounting lug into the corresponding position of the ceiling box 13, the ceiling box 13 and the mounting plate 11 can be fixedly connected by fasteners.

[0033] Furthermore, due to the exposed notch design formed by the clearance hole 132, moisture and dust can easily enter the interior of the lamp holder 1, damaging the hinge structure or circuit components. If a fixed shielding structure is used, it will limit the swing range of the adjustment rod, or cause shielding failure or structural interference during adjustment, making it unable to meet the needs of large-angle adjustment and resulting in a problem of insufficient protection and aesthetics. Therefore, the lamp holder 1 of this application also includes a sealing plate 14 with a ring-shaped flat plate structure.

[0034] In this embodiment, the sealing plate 14 passes through the inner ring through hole onto the extension rod 2; the outer ring of the sealing plate 14 rests on the bottom of the inner cavity of the ceiling box 13; when the extension rod 2 swings, it causes the sealing plate 14 to slide at the bottom of the inner cavity of the ceiling box 13. Furthermore, a gap is left between the inner ring of the sealing plate 14 and the outer wall of the extension rod 2 to accommodate fluctuations in the cross-sectional shape and area of ​​the clamping section of the sealing plate 14 on the extension rod 2 when the extension rod 2 swings; the outer ring size of the sealing plate 14 is larger than the inner diameter of the clearance hole 132 but smaller than the inner diameter of the ceiling box 13. Specifically, the size difference between the outer ring of the sealing plate 14 and the inner diameter of the ceiling box 13 can be designed based on the length of the diagonal side of the swing angle of the extension rod 2 on the projection plane of the sealing plate 14. The sealing plate 14 is a movable blocking device set between the extension rod 2 and the clearance hole 132. It will not cause structural interference to the swing adjustment of the extension rod 2 due to fixed blocking, and can dynamically block the exposed gap formed between the clearance hole 132 and the extension rod 2, taking into account both protection and aesthetics.

[0035] For further details, please refer to Figure 2 The sealing plate 14 is composed of a first clamping piece 141 and a second clamping piece 142.

[0036] In this embodiment, the inner ring through holes of the first clamping piece 141 and the second clamping piece 142 are both elliptical; the second clamping piece 142 is fixedly stacked on the first clamping piece 141, and the inner ring major axis of the first clamping piece 141 and the inner ring major axis of the second clamping piece 142 are perpendicular to each other in the vertical direction, that is, the extension rod 2 is clamped by the overlapping short axis of the first clamping piece 141 and the second clamping piece 142. Similarly, a gap is also left between the short axis of the first clamping piece 141 and the short axis of the second clamping piece 142 and the outer wall of the extension rod 2.

[0037] In this embodiment, the first clamping piece 141 has a set of mounting slots 1411 symmetrically arranged on both sides; the second clamping piece 142 is formed by two symmetrical structural pieces joined together, and the two structural pieces are fixed in the mounting slots 1411 by the two sides. Specifically, each end of the second clamping piece 142 has a locking foot corresponding to the mounting slot 1411. During assembly, the locking feet on both sides are locked in the mounting slots 1411 on both sides to constrain the second clamping piece 142 in the vertical direction; fastener mounting positions can be provided on each locking foot. After the two locking feet slide along the mounting slot to the target position, a fastener is installed at the fastener mounting position and abuts against the inner wall of the mounting slot 1411 to fix the second clamping piece 142 in the horizontal direction. Furthermore, by adjusting the distance between the two second clamping pieces 142 and replacing the first clamping piece 141, extension rods 2 with different outer diameters can be accommodated, improving the product's applicability and compatibility.

[0038] In one embodiment, please refer to Figure 2 and Figure 3 The top edge of the ceiling box 13 has a set of symmetrical U-shaped slots 131 facing downwards, and the bottom edge of the mounting plate 11 has a set of corresponding feet 111 facing downwards. When the ceiling box 13 and the mounting plate 11 are assembled, the feet 111 are engaged in the U-shaped slots 131 to assist in the installation positioning during assembly. At the same time, since the mounting plate 11 is embedded in the ceiling box 13 for assembly, the exposed feet 111 of the mounting plate 11 can also serve as gripping points to assist in the separation of the mounting plate 11 from the ceiling box 13 during disassembly.

[0039] In one embodiment, please refer to Figure 5 The lamp body 4 includes an arc-shaped lampshade 41 and structural side plates 42 mounted at both ends of the lampshade 41. The lamp body 4 is fixedly connected to the power supply box 3 by mounting connecting plates 31 on the outer side of each structural side plate 42; the structural side plates 42 and the connecting plates 31 are connected by a central pivot or several arc-shaped holes, allowing the lamp body 4 to rotate around the central pivot or the arc-shaped holes. By allowing the lamp body 4 to rotate and adjust relative to the power supply box 3, and in conjunction with the adjustable mechanism of the extension rod 2 and the lamp holder 1, the pool light of this application can obtain a wider range and greater illumination angle adjustment capability, further optimizing its adaptability to different usage scenarios.

[0040] For further details, please refer to Figure 6The lampshade 41 is composed of a decorative panel 411 and a heat sink 412. The light-emitting part 43 is arranged on the heat sink 412, and the reflective part is arranged on the decorative panel 411. The split design helps to effectively separate the different functional areas of the lampshade 41. For example, the heat sink 412 can be processed and designed using gradient thickness substrate design, surface microstructure treatment, etc. The gradient thickness substrate design thickens the area directly below the heat source and gradually thins towards the edge to form a path for heat flow convergence and diffusion, reducing thermal resistance and preventing local overheating of the heat sink 412. The surface microstructure treatment can enhance the radiative heat dissipation capacity by micro-protruding or roughening the surface of the heat sink 412.

[0041] In one embodiment, the decorative panel 411 is provided with at least one support rib extending along the length direction; the support rib has a through channel and internal threads are machined at both ends of the through channel, that is, the support rib can provide support for the thin decorative panel 411 and at the same time provide certain assembly holes for the structural side panel 42.

[0042] In one embodiment, please refer to Figure 4 and Figure 7 The power supply box 3 includes a mounting bracket 32 ​​and an electrical box 33. The mounting bracket 32 ​​is fixedly connected to the extension rod 2; the connecting plate 31 is assembled and fixed at both ends of the mounting bracket 32 ​​and the electrical box 33, sealing the interior of the power supply box 3 while connecting to the lamp body 4. The electrical box 33 is snapped onto the mounting bracket 32, forming the internal cavity of the power supply box 3, and a clearance is provided between the electrical box 33 and the lamp body 4, which allows the lamp body 4 to rotate and adjust its position while also providing sufficient heat dissipation space for the light source devices on the lamp body 4 and the drive power supply 34 inside the electrical box 33.

[0043] Furthermore, the electrical box 33 includes two mutually bent structural plates, each structural plate having at least one mounting slot. Several driving power supplies 34 of the lamp body 4 are distributed and mounted on each mounting slot. The distributed arrangement facilitates heat dissipation inside the power box 3 when the lamp is in operation. At the same time, the assembly form of the mounting slots facilitates the installation and replacement of the driving power supplies 34.

[0044] In summary, this application optimizes the lamp body structure and light source layout, and incorporates a dedicated reflective structure design to ensure that the upward-emitting light is evenly diffused after reflection. This effectively avoids problems such as bright spots and shadows that occur with traditional overhead lighting, while also preventing glare interference from direct light on swimmers' eyes. This significantly improves the uniformity and comfort of overhead lighting in the pool area, creating a high-quality lighting environment for users. By integrating the adjustment and reflective structures, the lamp body can be tilted at an angle via the adjustment mechanism. Combined with the guiding effect of the reflective structure, precise adjustment of the lighting area is achieved. This allows for flexible adjustment of the overhead lighting coverage based on the size of the pool and the usage scenario, overcoming the limitation of fixed and unadjustable illumination areas in existing pool lighting fixtures, thus enhancing adaptability. Furthermore, the lighting and adjustment structure of this application is not only suitable for pool scenarios but can also be flexibly adapted to other venues requiring uniform overhead lighting, such as stadiums and large leisure venues.

[0045] The above are merely optional embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
