Description

Technical Field

[0001] This utility model relates to the technical field of fountain lights, and in particular to a one-piece fountain light structure with improved waterproof performance. Background Technology

[0002] A fountain light is an underwater lighting device specifically designed for fountain water features. It is typically installed submerged and fixed to the bottom of the pool or inside the fountain structure. Its core function is to project light onto the jets, curtains, or sprays of water using high-brightness LEDs or fiber optic light sources, combined with professional-grade waterproof performance (such as IP68) and corrosion-resistant materials (such as stainless steel and high-strength plastics). This significantly enhances the visual appeal of the fountain at night or in low-light environments, highlighting the water flow patterns, color variations, and dynamic beauty. It creates a dreamy, dazzling, or dramatic atmosphere for water features and is a key device for enhancing the artistic effect of water features in public places such as city squares, garden landscapes, and building atriums.

[0003] Based on this, Chinese patent document CN206504207U discloses a fountain light, which includes a housing and a water pipe passing through the center of the housing. The housing is an open-top cylindrical housing, comprising an upper housing and a lower housing, with the upper and lower ends of the water pipe extending out of the upper and lower housings respectively. Fixing holes are evenly distributed on the side walls of the upper and lower sides of the water pipe, and connecting rods for fixing are provided in these fixing holes. Multiple screw holes are evenly distributed along the outer circumference of the upper and lower housings, allowing the upper and lower housings to be fastened together with screws. The fountain light disclosed in this patent document has screw holes in both the upper and lower housings, resulting in a tighter fixation and a more robust and reliable structure. It also has a larger size, enabling large-area illumination of the fountain landscape and achieving higher beam illumination.

[0004] However, existing fountain lights still suffer from insufficient waterproofing. Specifically, in the existing solutions, multiple screw holes are evenly distributed along the outer circumference of the upper and lower housings, allowing them to be fastened together. However, current fountain lights require the nozzles to pass through the center of the light body to create the effect of water spraying from the light strip around the nozzles; the center of existing fountain lights is closed, making it impossible to install nozzles; drilling holes directly into the light body is also problematic; and waterproofing around the drilled holes is difficult.

[0027] Please refer to the following: Figures 1 to 4 This utility model discloses a one-piece fountain light structure with improved waterproof performance, comprising: a lamp cover 1, a hollow tube column 2, a heat dissipation lamp cup 3, several LED beads 4, a waterproof cable outlet structure 5, a translucent glass cover 6, an inner waterproof ring 7, an outer waterproof ring 8, a pressure cap 9, and an ear cap 10; the hollow tube column 2 is integrally provided in the middle of the lamp cover 1, and the heat dissipation lamp cup 3 is arranged in the inner cavity of the lamp cover 1, with the middle part of the heat dissipation lamp cup 3 abutting and connected to the hollow tube column 2, and several LED beads... 4. The heat sink lamp cup 3 is evenly distributed on the lamp; the waterproof cable outlet structure 5 is located at the bottom of the inner cavity of the lamp cover 1; the light-transmitting glass cover 6 is located at the upper part of the lamp cover 1; the inner waterproof ring 7 is located in the inner ring of the light-transmitting glass cover 6; the outer waterproof ring 8 is located in the outer ring of the light-transmitting glass cover 6; the pressure cap 9 passes through the middle of the inner waterproof ring 7 and is connected to the hollow tube column 2; the ear cap 10 presses the outer waterproof ring 8 and is connected to the lamp cover 1.

[0028] Specifically, when the integrated fountain light structure of this utility model with improved waterproof performance is installed in the installation environment, for example, when installed in a preset position of an external fountain, the nozzle of the external fountain can pass through the inner cavity of the hollow tube column 2, so that water can gush out from the center of the fountain light; the hollow tube column 2 and the lamp cover 1 can be integrally formed, for example, by die casting, stamping and stretching; or after the hollow tube column 2 and the lamp cover 1 are formed separately, the connection between the two can be tightly connected by welding, and at the same time, glue can be evenly applied between the weld seams to enhance the sealing connection between the two. Therefore, it avoids the need to separately screw the lamp cover 1 and the hollow tube column 2 and add an additional waterproof ring when connecting with threaded parts in the prior art. Furthermore, the one-piece molding method allows for better sealing of the bottom of the lamp cover 1, thereby enabling the integrated fountain light structure of this invention, which improves waterproof performance, to achieve superior protective performance. For example, it can achieve an IP68 waterproof and dustproof rating, thus improving the protective capability of the fountain light.

[0029] Specifically, the lamp cover 1 has a main cover 101, a cover ear 102, and an ear surround 103; the cover ear 102 is provided on the top of the main cover 101, and the ear surround 103 is provided around the perimeter of the cover ear 102.

[0030] Furthermore, the hollow tube column 2 is provided with a hollow tube body 201 and a plurality of fasteners 202; the hollow tube body 201 passes through the middle of the main cover 101, and the plurality of fasteners 202 are evenly distributed at the lower part of the hollow tube body 201. In a specific embodiment, the hollow tube body 201 and the main cover 101 are respectively formed by stamping and deep drawing processes, and when the hollow tube body 201 is inserted into the main cover 101, the connection between the two is connected by a welding process, and then the weld is evenly coated with glue to achieve a more stable sealing connection. In addition, the nozzle of the external fountain can be inserted through the bottom of the hollow tube body 201, and the nozzle is fastened by the fasteners 202.

[0031] Furthermore, the heat dissipation lamp cup 3 has a cup body 301, an inner folded edge 302, and an outer folded edge 303; the cup body 301 is suspended in the inner cavity of the main cover 101, and a plurality of LED lamp beads 4 are evenly distributed on the cup body 301; the inner folded edge 302 is provided on the inner ring of the cup body 301, and the inner folded edge 302 is abutted and connected to the periphery of the hollow tube 201; the outer folded edge 303 is provided on the outer ring of the cup body 301, and the outer folded edge 303 is abutted and connected to the inner wall of the main cover 101. Specifically, by connecting the inner folded edge 302 to the hollow tube column 2 and the outer folded edge 303 to the main cover 101, the cup body 301 can be suspended in the main cover 101. This allows the heat generated by the LED beads 4 to dissipate within the cavity of the main cover 101, preventing heat buildup in the LED beads 4 and thus avoiding damage.

[0032] Furthermore, the cable waterproof discharge structure 5 includes a nut and bolt tube 501, a soft rubber tube 502, a flower-shaped extrusion sleeve 503, a threaded connection end sleeve 504, a bolt waterproof gasket 505, and a fastening nut 506. The upper end of the nut and bolt tube 501 passes through the bottom of the main cover 101, the soft rubber tube 502 passes through the lower part of the nut and bolt tube 501, and the flower-shaped extrusion sleeve 503 is fitted outside the soft rubber tube 502 and then passes through the lower part of the nut and bolt tube 501. The threaded connection end sleeve 504 is threadedly connected to the lower part of the nut and bolt tube 501. The portion of the nut and bolt tube 501 that extends into the main cover 101 is fitted with the bolt waterproof gasket 505. The fastening nut 506 pressurizes the bolt waterproof gasket 505 to the upper part of the nut and bolt tube 501 from inside the main cover 101 through threads.

[0033] Specifically, signal cables and electrical cables can be inserted into the hollow tube of the nut and bolt tube 501, thereby entering the bottom of the main cover 101, and are connected to each of the LED beads 4 on the cup body 301 for power supply and control. The fastening nut 506 pressurizes the bolt waterproof gasket 505 from inside the main cover 101 and connects it to the bottom of the main cover 101 to waterproof and dustproof the connection gap between the nut bolt tube 501 and the main cover 101. When the cable passes through the nut bolt tube 501, it also passes through the middle of the soft rubber tube 502 and the flower-shaped extrusion sleeve 503. The user can continuously squeeze the flower-shaped extrusion sleeve 503 by rotating the threaded connection end sleeve 504. The flower-shaped extrusion sleeve 503 will squeeze the soft rubber tube 502 as the threaded connection end sleeve 504 moves upward, and then the soft rubber tube 502 will squeeze the outer wall of the cable, thereby achieving waterproof and dustproof functions at the cable insertion point. Similarly, the flower-shaped extrusion sleeve 503 will release the pressure on the soft rubber tube 502 as the threaded connection end sleeve 504 moves downward, thereby loosening the cable. Specifically, the upper part of the extrusion sleeve 503 is a collar, and several pins are evenly arranged at the lower part of the collar, with a pressure protrusion at the end of each pin; thus, the extrusion action of the aforementioned soft rubber tube can be realized.

[0034] Furthermore, the inner ring of the light-transmitting glass cover 6 can cover the heat dissipation lamp cup 3, allowing the light from the LED beads 4 installed in the heat dissipation lamp cup 3 to pass through. Subsequently, the inner waterproof ring 7 and the outer waterproof ring 8 can be connected to the inner and outer rings of the light-transmitting glass cover 6 respectively using an encapsulation process. Both the inner waterproof ring 7 and the outer waterproof ring 8 can be made of materials such as silicone or rubber. Therefore, when the pressure cap 9 is threaded to the upper part of the hollow tube column 2, the upper edge of the pressure cap 9 can pressurize the inner waterproof ring 7, thereby sealing the gap between the light-transmitting glass cover 6 and the upper part of the hollow tube 201, thus achieving a waterproof function at that location.

[0035] Furthermore, the pressure cap 9 has a pressure cap connecting pipe 901 and an inner clamping ring 902; the pressure cap connecting pipe 901 is connected to the upper part of the hollow tube body 201, and the inner clamping ring 902 is provided on the upper outer periphery of the pressure cap connecting pipe 901, and the inner clamping ring 902 abuts against and connects to the inner waterproof ring 7.

[0036] Furthermore, the ear cover 10 has an outer clamping ring 1001 and a plurality of ear cover connecting posts 1002; the outer clamping ring 1001 is abutted against the outer waterproof ring 8, and a plurality of ear cover connecting posts 1002 are evenly distributed below the outer clamping ring 1001, each of the ear cover connecting posts 1002 being connected to the main cover body 101. Specifically, the ear cover connecting posts 1002 can be connected by nuts, thereby tightly abutting the outer clamping ring 1001 against the outer waterproof ring 8, thus achieving a waterproof connection between the outer periphery of the light-transmitting glass cover 6 and the main cover body 101.

[0037] In summary, the integrated fountain light structure of this utility model with improved waterproof performance includes a lamp cover 1, a hollow tube column 2, a heat dissipation lamp cup 3, several LED beads 4, a waterproof cable outlet structure 5, a translucent glass cover 6, an inner waterproof ring 7, an outer waterproof ring 8, a pressure cap 9, and an ear cap 10. The hollow tube column 2 is integrally provided in the middle of the lamp cover 1, and the heat dissipation lamp cup 3 is provided in the inner cavity of the lamp cover 1. The middle part of the heat dissipation lamp cup 3 is abutted and connected to the hollow tube column 2. Several LED beads 4 are provided. D-type LED beads 4 are evenly distributed on the heat dissipation lamp cup 3; the waterproof cable outlet structure 5 is located at the bottom of the inner cavity of the lamp cover 1; the light-transmitting glass cover 6 is located at the upper part of the lamp cover 1; the inner waterproof ring 7 is located on the inner ring of the light-transmitting glass cover 6; the outer waterproof ring 8 is located on the outer ring of the light-transmitting glass cover 6; the pressure cap 9 passes through the middle of the inner waterproof ring 7 and is connected to the hollow tube column 2; the ear cap 10 presses the outer waterproof ring 8 and is connected to the lamp cover 1. The connection between the hollow tube 201 and the main cover 101 can be connected by welding, and then glue is evenly applied to the weld to achieve a more stable sealing connection; thus, this welded connection method can reduce the use of rubber rings, and the waterproof installation is simpler, reducing assembly steps while also having strong waterproof performance. Therefore, this utility model, a one-piece fountain light structure with improved waterproof performance, solves the technical problem of how to improve the protective performance of fountain lights.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
