Description

Technical Field

[0001] This utility model relates to the field of grid lighting, and more specifically, to a pipe-insertion type grid lighting. Background Technology

[0002] Space frame lights are a type of lighting equipment widely used in large spaces such as industrial plants, warehouses, stadiums, and exhibition venues. Traditional space frame lights often adopt an integrated design, which has the following defects and shortcomings:

[0003] First, there is a lack of flexibility. Traditional grid lights mostly use fixed-angle brackets or simple hinge structures for adjustment, which have a limited adjustment range and are cumbersome to operate. They often require tools and need to be repositioned and measured each time they are used, making it difficult to achieve fast and accurate multi-directional positioning and resulting in low lighting efficiency.

[0004] Secondly, it has low adaptability to different scenarios. Traditional grid lights, due to their fixed structure, are difficult to cope with the changing needs of different exhibition spaces. For example, when switching between indoor and outdoor spaces, they often face structural compatibility issues such as waterproofing and wind resistance. General-purpose lighting solutions cannot meet the precise lighting requirements of high-demand scenarios such as car launches, while special scenarios such as jewelry exhibitions lack the ability to adjust quickly.

[0033] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0034] Please see Figures 1 to 7 The present invention provides a pipe-insertion type grid light according to one embodiment.

[0035] Specifically, the pipe-insertion type grid light includes a light-emitting unit 1 and a support unit 2.

[0036] The light-emitting unit 1 includes a rear lampshade 11, a heat sink 12, an LED light panel 13, a lens 14, and a front panel 15, wherein a receiving space is formed between the lampshade 11 and the panel 15, and the heat sink 12, the LED light panel 13, and the lens 14 are sequentially arranged in the receiving space between the lampshade 11 and the panel 15.

[0037] The support unit 2 includes a universal joint 21, a support rod 22, and a pipe transition component 23.

[0038] A hexagonal nut 111 is fixedly installed inside the lampshade 11, and the first end of the universal bracket 21 is threadedly connected to the light-emitting unit 1 through the hexagonal nut 111.

[0039] The first end of the support rod 22 has an external thread, which is connected to the internal thread of the short pipe thread at the second end of the universal joint 21. A branch pipe 221 is fixedly connected to the side wall of the support rod 22. The branch pipe 221 is arranged at an angle to the support rod 22, and the included angle can be any angle between 0° and 180°, excluding 0° and 180° themselves. The branch pipe 221 is sleeved on the pipe transition piece 23. The branch pipe 221 can be circular, square, hexagonal, elliptical, etc.; preferably, the branch pipe 221 is square. When the square branch pipe 221 is engaged with the pipe transition piece 23, it can prevent relative rotation and ensure connection stability.

[0040] The pipe transition component 23 includes an upper sleeve 231 and a lower sleeve 232. The inner wall of the upper sleeve 231 is fitted with the branch pipe 221, and the lower sleeve 232 is used to insert an external tubular support 4, so that the pipe is inserted into the grid light and supported by the external tubular support 4. There are several lower sleeves 232, and each lower sleeve 232 differs from the branch pipe 221 in at least one of the characteristics of shape and size. The lower sleeves 232 of different specifications from the branch pipe 221 can be quickly adapted to the circular, square or irregularly shaped external tubular support 4, realizing plug-and-play, solving the installation limitation problem caused by the single interface of traditional grid lights, and significantly improving the equipment deployment efficiency.

[0041] Preferably, the upper sleeve 231 has a hemispherical outer shape and a square inner wall, the lower sleeve 232 is square, and the outer tubular support 4 is square. The hemispherical upper sleeve 231 can avoid bumps and knocks, the square inner wall can accurately fix the branch pipe 221 to prevent rotation, and the square lower sleeve 232 can be directly inserted into the square outer tubular support 4 to achieve quick alignment and installation. The operation is convenient, and the square contact surface can improve the connection strength and stability.

[0042] In a preferred embodiment, the lampshade 11 has a first limiting member 112 at the top and bottom of its inner side and a second limiting member 113 on its side wall.

[0043] The first limiting member 112 and the second limiting member 113 are wedge-shaped block structures: the first limiting member 112 is symmetrically distributed along the perpendicular bisector of the width direction of the lampshade 11, with at least two sets at the top and bottom of the lampshade 11, for a total of no less than four sets; the second limiting member 113 is symmetrically distributed along the perpendicular bisector of the length direction of the lampshade 11, with at least two sets on the left and right sides of the lampshade 11, for a total of no less than four sets. Preferably, there are four sets of the first limiting member 112 and four sets of the second limiting member 113.

[0044] The wedge-shaped structure, combined with the symmetrical layout, ensures that the vertical limiting force on the heat sink 12 is evenly distributed, avoiding stress concentration on one side. The double sets of first limiting members 112 at the top and bottom of the lamp cover 11 form a four-point support, ensuring that the heat sink 12 does not deflect or shift under vibration. The wedge-shaped inclined surface automatically centers when guiding the heat sink 12 into the lamp cover 11, improving the tolerance rate of assembly tolerance. The symmetrical distribution design also eliminates the directional requirements for installing the heat sink 12, improving assembly convenience.

[0045] The heat sink 12 has heat sink hooks 121 on its upper and lower edges, and a groove 122 is formed on the rear side of the heat sink hooks 121. A limiting block 123 is formed directly above the upper edge groove 122 and directly below the lower edge groove 122. Multiple wavy heat dissipation strips 124 are arranged horizontally on the rear side of the heat sink 12 to increase the heat dissipation area, optimize airflow, and improve heat dissipation efficiency. The limiting block 123 is in planar contact with the first limiting member 112 to restrict the vertical displacement of the heat sink 12.

[0046] Preferably, the LED light board 13 is snapped into the space formed by the heat sink hook 121. The upper and lower sets of heat sink hooks 121 together restrict the vertical displacement of the LED light board 13. At the same time, the inclined surface of the second limiting member 113 forms surface contact with the LED light board 13, restricting the horizontal displacement of the LED light board 13.

[0047] Preferably, the lens 14 is bonded to the LED light panel 13 to avoid mechanical pressure damaging the optical components.

[0048] Preferably, the panel 15 has panel hooks 151 and multiple positioning protrusions 152 at the top and bottom of its rear side. The panel hooks 151 are symmetrically distributed along the vertical line of the width of the panel 15, with at least two sets at the top and at the bottom, for a total of no less than four sets. A third limiting member 153 is provided on the side of the panel 15. The third limiting member 153 is a wedge-shaped inclined surface and is symmetrically distributed along the vertical line of the length of the panel 15. At least one set is provided on the left and right sides of the panel 15, for a total of no less than two sets. Preferably, there are four panel hooks 151 and two third limiting members 153.

[0049] Preferably, the positioning protrusion 152 and the limiting block 123 are in planar contact engagement to restrict the Z-axis displacement of the panel 15; the panel hook 151 and the groove 122 of the heat sink 12 form a snap-fit ​​engagement to restrict the X-axis displacement of the panel 15; and the lateral working surface of the third limiting member 153 forms a surface contact with the inner wall of the lampshade 11 to restrict the Y-axis displacement of the panel 15. The three-point positioning system composed of the positioning protrusion 152 and the third limiting member 153 strictly controls the overall displacement tolerance of the panel 15.

[0050] The modular design enables tool-free operation of each component of the light-emitting unit 1 through snap-fit ​​and limiting cooperation, shortening the assembly time of a single light-emitting unit 1 and reducing maintenance time. At the same time, it allows each component to be replaced or upgraded independently, facilitating the development of derivative models and balancing production efficiency and reliability. The heat sink 12 is first fixed vertically, then horizontally limited by the LED light board 13, and finally the panel 15 is locked independently. The multi-level limiting reduces the cumulative risk of assembly tolerance between components. The wavy heat dissipation strips 124 of the heat sink 12 and the heat dissipation holes of the lamp cover 11 form a modular heat dissipation channel, supporting rapid adaptation to different power models.

[0051] In a preferred embodiment, the rear outer surface of the lampshade 11 is provided with a composite heat dissipation hole structure, including strip-shaped holes 114 and circular holes 115 symmetrically distributed along the vertical line of the width direction of the lampshade 11. At least two circular holes 115 are symmetrically arranged outside the strip-shaped holes 114, with a total number of at least four, about the vertical line of the width direction of the lampshade 11. The rear inner surface of the lampshade 11 is provided with multiple heat dissipation protrusions 116. The heat dissipation protrusions 116 are elongated strip structures, and the projected position of each heat dissipation protrusion 116 is located within the gap area between adjacent strip-shaped holes 114.

[0052] In this composite heat dissipation structure, the strip-shaped holes 114 promote axial airflow, and the circular holes 115 induce the worm gear to enhance heat transfer. The two work together to effectively improve the convective heat transfer coefficient. The symmetrical layout also ensures the structural strength of the lamp cover 11. In addition, the heat dissipation protrusions 116 can increase the heat dissipation area and guide the airflow to form turbulence, further improving the heat dissipation efficiency.

[0053] In a preferred embodiment, the LEDs 131 are arranged in a grid pattern on the LED panel 13, balancing localized dimming and uniformity. The lower end of the LED panel 13 has a surface mount end 132, achieving a compact and reliable electrical connection through high-density surface mount technology, facilitating automated production and rapid maintenance. Preferably, 24 LEDs 131 are arranged at equal intervals in an 8x3 matrix, with each LED 131 independently corresponding to a lens 14.

[0054] In a preferred embodiment, the second end of the support rod 22 is detachably connected to an anti-pull member 3. The bottom of the anti-pull member 3 is provided with an elliptical hole 31, which is used to clamp the external power cord to prevent the line from becoming loose or making poor contact due to pulling, thereby improving safety. The anti-pull member 3 is sleeved on the support rod 22 to ensure a firm connection while facilitating disassembly and maintenance.

[0055] In a preferred embodiment, the support rod 22 and the universal bracket 21 are hollow structures. The support rod 22 has a wiring channel, and the universal bracket 21 has a through hole. The power cable passes through the elliptical hole 31 of the anti-pull hole 3, the wiring channel in the support rod 22, and the through hole in the universal bracket 21 in sequence before being electrically connected to the LED light board 13. This forms a concealed wiring, which protects the power cable with the metal structure throughout, avoiding mechanical damage. At the same time, there are no exposed cables, making it aesthetically pleasing and neat.

[0056] In summary, the universal joint of this utility model's pipe-insertion type grid light allows for multi-angle adjustment in both horizontal and vertical directions, enabling precise control of the lighting direction and optimization of light distribution based on actual conditions. The branch pipes, in conjunction with pipe transition fittings, perfectly adapt to external tubular support components with different orientations, eliminating the need for additional adapter rings. Furthermore, the multi-specification lower sleeves of this utility model's pipe-insertion type grid light can quickly adapt to round, square, or irregularly shaped support rods. Combined with the 360° stepless adjustment of the universal joint, it can adapt to different installation positions and lighting needs, perfectly fitting both indoor and outdoor environments. For example, it meets the stringent requirements of jewelry exhibitions for precise lighting and addresses the wind and earthquake resistance needs of open-air stages.
