Description

Technical Field

[0001] This utility model relates to the field of LED lighting fixtures, specifically to LED lighting fixtures that can be arbitrarily combined and connected in series. Background Technology

[0002] LED lighting fixtures, or Light Emitting Diode (LED) lighting devices, are lighting equipment that uses solid-state semiconductor materials to produce light. Due to their high efficiency, energy saving, long lifespan, and environmental friendliness, LED lighting fixtures are widely used in many fields. In landscape design, LED lighting fixtures are used for decorative lighting and are also an important component of advertising media such as billboards and displays. For example, LED light strings are often used for decoration, outdoor lighting, and landscaping.

[0003] Existing technology discloses a series-connected LED light source module and its assembly. The series-connected LED light source module includes a light-transmitting cover, an insulating mounting frame, and LED light-emitting units located between the light-transmitting cover and the insulating mounting frame. The two openings of the light-transmitting cover are fixed to the two ends of the insulating mounting frame. The insulating mounting frame has two parallel, spaced-apart first wiring channels running through it along its length. Each first wiring channel contains a conductor with an axial opening formed by a metal spring. The two conductors are electrically connected to the LED light-emitting units. By placing conductors in the first wiring channels, a bidirectional input terminal is provided to obtain power, simultaneously illuminating each series-connected LED light source module. The modules can be slidably connected and assembled into a combined lamp with a certain length and shape via metal guide rails, allowing for arbitrary combination and series connection.

[0004] However, despite the widespread application of existing LED lighting fixtures in various fields, some shortcomings still exist. The overall structure of existing series-connected LED lighting fixtures is relatively complex, which not only increases the assembly difficulty in the LED lighting fixture production process but also directly drives up the overall manufacturing cost, thus adversely affecting the production efficiency and cost control of LED lighting fixtures. Furthermore, the connection structure between the existing series-connected LED light source module and the guide rail is unstable. Specifically, the LED light source module is prone to radial rotation on the guide rail. This unstable connection weakens the firmness of the connection between the LED light source module and the guide rail and can also affect mutual conductivity, thereby affecting the stable installation and use of the LED light source module. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned defects and provide LED lamps that can be arbitrarily combined and connected in series, so as to solve the technical problems in the background art that the existing series LED lamps have a relatively complex structure, which affects production efficiency and manufacturing costs, and that the connection of the existing series LED lamps is easy to rotate, affecting the stable connection and use.

[0006] The objective of this utility model is achieved through the following means:

[0007] An LED lamp that can be arbitrarily combined and connected in series includes a light-emitting body and a power cord for supplying power to the light-emitting body. The light-emitting body consists of an internally conductive lampshade, a connecting bracket disposed within the lampshade, an LED light-emitting unit for emitting light, and two end caps. The connecting bracket has an axially extending wire channel inside, and several conductive springs for holding and wedging the power cord are disposed within the connecting bracket. The conductive springs have holding contact ends extending into the wire channel, and are electrically connected to the LED light-emitting unit through connecting ends. The power cord includes two conductors and a wire body for mounting the conductors. The wire body has two grooves for mounting the conductors along the axial direction. The light-emitting body is connected in series with the power cord through the wire channel, and the light-emitting body can slide along the axial extension direction of the wire body through the holding contact ends. It is wedged and held by the holding contact ends on the conductive springs and electrically connected to the conductors.

[0008] Further as described above, the connecting bracket includes a first bracket and a second bracket for splicing the first bracket. The inner sides of the first bracket and the second bracket are spliced ​​together by snap-fit ​​protrusions and snap-fit ​​grooves. The inner sides of both the first bracket and the second bracket are formed with mounting grooves for installing conductive springs. The connecting ends of the conductive springs pass through the mounting grooves and are electrically connected to the LED light-emitting unit.

[0009] The first and second brackets are joined together by matching snap-fit ​​protrusions and snap-fit ​​grooves, creating a threading channel on the inner surface of the joined area for connecting power cords. Specifically, both the first and second brackets have mounting grooves on their inner surfaces for mating conductive springs, allowing the conductive springs to be installed between the first and second brackets. This simplifies the assembly and installation of the conductive springs and connecting brackets, improving the efficiency of the connection.

[0010] Furthermore, as described above, four conductive springs are provided and symmetrically installed in pairs within the mounting groove. The retaining contact ends of two adjacent conductive springs form a retaining gap for retaining the power cord. The two adjacent conductive springs can continuously provide clamping force to the wire-passing channel through the retaining contact ends, so that the conductive springs are clamped and limited to the conductor through the retaining contact ends.

[0011] The conductive spring is stamped with a retaining contact end that extends into the wire channel. The retaining contact ends on the two symmetrical conductive springs can be paired with the wire grooves on both sides of the wire body and make contact with the conductors in the wire grooves, thereby providing power to the LED light-emitting unit.

[0012] When the light source is connected in series with the power cord through the wiring channel, two symmetrically arranged conductive springs can make contact with the two conductors respectively. At the same time, the wire groove on the wire body allows the conductive springs to slide along the wire groove by holding the contact end, reducing the radial rotation of the light source on the wire body and improving the stability of the series connection of the light source.

[0013] Specifically, two symmetrically arranged conductive springs continuously provide clamping force to the wire channel, thereby enhancing the stability of the connection between the light source and the power cord.

[0014] Furthermore, as described above, both ends of the first bracket and the second bracket are formed with threaded connection portions. The first bracket and the second bracket are spliced ​​together to form a cylindrical shape. Two end caps are disposed at both ends of the lampshade, and both end caps are provided with through holes for wire passing. The end caps are screwed to the threaded connection portions through threaded holes.

[0015] By setting threaded connection parts for connecting end caps, the pairing and splicing of the first bracket and the second bracket can be further ensured. At the same time, the two end caps can limit and fix the lampshade.

[0016] Furthermore, as described above, the lampshade is cylindrical, spherical, elliptical, lantern-shaped, or polyhedral in shape.

[0017] Alternatively, the lampshade can be made of glass or PC material.

[0018] Furthermore, as described above, the LED light-emitting unit includes a flexible circuit board that surrounds the connecting bracket and a plurality of LED light sources that are evenly distributed on the flexible circuit board. The flexible circuit board is arranged to surround the outer surface of the connecting bracket and is electrically connected to the connecting end.

[0019] Furthermore, the flexible circuit board also integrates LED chips, which can output corresponding control signals to adjust the luminous parameters of the LED light source. These luminous parameters include output lumens, color temperature, light color, and color rendering index. By utilizing pre-set LED chips, LED light-emitting units with different light source configurations can be provided, allowing for the customization of lighting fixtures with diverse styles to suit different occasions and enriching the variety of lighting products.

[0020] By using a flexible circuit board arranged around the perimeter to create a 360-degree three-dimensional light source, the uniform illumination method can provide light that is evenly diffused in all 360 degrees, minimizing the problem of shadows.

[0021] Furthermore, as described above, an insulating portion is formed in the middle of the wire body, and two conductors are symmetrically snapped into the wire grooves on both sides of the wire body, and the cross-section of the wire body is "I" shaped.

[0022] The wire grooves on both sides of the wire body form guide grooves for matching and holding contact ends, allowing the light-emitting body to slide freely along the wire grooves for adjustment. Power is supplied to the LED light-emitting unit through the contact between the conductor and the holding contact end. The clamping of the power wire by the two conductive springs ensures the stability of the power contact, thereby enabling the LED light-emitting unit to emit light.

[0023] The beneficial effects of this utility model are as follows: The modular design of the LED lamp body and power cord allows users to freely combine and connect them as needed, increasing flexibility and adaptability. The overall assembly structure of the lamp body is simple, improving assembly efficiency and reducing manufacturing costs. The grooves on both sides of the power cord allow for the installation of paired conductors. These grooves also form sliding channels for locking the contact ends. The pairing of the locking contact ends with the grooves allows the lamp body to slide freely along the axial direction of the grooves. The pairing of the locking contact ends with the grooves also limits the radial rotation of the lamp body, improving the stable connection between the lamp body and the power cord. The lamp body slides along the axial direction of the power cord through the wire channel and is wedge-locked with the conductors in the grooves by the locking contact ends of the conductive springs. This allows for flexible and secure series connection of the lamp bodies. Users can easily increase or decrease the number of bulbs as needed, while ensuring stable operation of each bulb. The lamp body has advantages such as arbitrary length splicing and extension, diverse product styles, and simple structure. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0035] In this embodiment, refer to Figures 1-8 The specific implementation of the LED lamp, which can be arbitrarily combined and connected in series, includes a light-emitting body 100 and a power cord 200 for supplying power to the light-emitting body 100. The light-emitting body 100 consists of an internally conductive lamp cover 101, a connecting bracket 102 disposed within the lamp cover 101, an LED light-emitting unit 103 for emitting light, and two end caps 104. The connecting bracket 102 has an axially penetrating wire channel 105 inside, and a plurality of conductive springs 106 for holding and wedging the power cord 200 are disposed inside the connecting bracket 102. The conductive springs 106 have clamping features extending into the wire channel 105. The contact end 107 and the conductive spring 106 are electrically connected to the LED light-emitting unit 103 through the connection end. The power line 200 includes two conductors 201 and a wire body 202 for mounting the conductors 201. The wire body 202 has two wire grooves 203 for mounting the conductors 201 in the axial direction. The light-emitting lamp body 100 is connected in series with the power line 200 through the wire passage 105. The light-emitting lamp body 100 can slide along the axial extension direction of the wire body 202 through the holding contact end 107. The holding contact end 107 on the conductive spring 106 is wedge-locked with the conductor 201 and electrically connected.

[0036] The connecting bracket 102 includes a first bracket 1021 and a second bracket 1022 for splicing the first bracket 1021. The inner sides of the first bracket 1021 and the second bracket 1022 are provided with snap-fit ​​protrusions 1023 and snap-fit ​​grooves 1024 for splicing each other. The inner sides of the first bracket 1021 and the second bracket 1022 are formed with mounting grooves 1025 for installing conductive spring pieces 106. The connecting end of the conductive spring piece 106 passes through the mounting groove 1025 and is electrically connected to the LED light-emitting unit 103.

[0037] The first bracket 1021 and the second bracket 1022 are joined together by a snap-fit ​​protrusion 1023 and a snap-fit ​​groove 1024, so that the inner surface of the joint has a wire passage 105 for connecting the power cord 200. Specifically, the inner surface of both the first bracket 1021 and the second bracket 1022 is provided with a mounting groove 1025 for mates with conductive springs 106, so that the conductive springs 106 can be installed between the first bracket 1021 and the second bracket 1022. The combination and installation of the conductive springs 106 and the connecting bracket 102 is simple and improves the efficiency of the combination connection.

[0038] Four conductive spring pieces 106 are provided and symmetrically installed in pairs in the mounting groove 1025. The clamping contact ends 107 of two adjacent conductive spring pieces 106 form a clamping gap 108 for clamping the power line 200. The two adjacent conductive spring pieces 106 can continuously provide clamping force to the wire passage 105 through the clamping contact ends 107, so that the conductive spring pieces 106 are clamped and limited to the conductor 201 through the clamping contact ends 107.

[0039] The conductive spring 106 is stamped with a retaining contact end 107 extending toward the wire passage 105. The retaining contact ends 107 on the two symmetrical conductive springs 106 can be paired with the wire grooves 203 on both sides of the wire body 202 and contact the conductors 201 in the wire grooves 203, thereby providing power to the LED light-emitting unit 103.

[0040] The design of the conductive spring 106 allows the power cord 200 to achieve a stable and reliable electrical connection through a simple wedging action, eliminating the need for screws or other fasteners and greatly simplifying the installation process. The extended design of the retaining contact end 107 ensures good electrical contact in the series connection. The power cord 200 adopts a design including two conductors 201 and a wire body 202, with two wire grooves 203 opened in the wire body 202 for mounting the conductors 201. This structure not only facilitates manufacturing and assembly.

[0041] When the light-emitting lamp body 100 is connected in series with the power line 200 through the wire channel 105, the two conductors 201 can be contacted by two symmetrically arranged conductive springs 106 respectively. At the same time, the conductive springs 106 can slide along the wire groove 203 through the clamping contact end 107, which reduces the radial rotation of the light-emitting lamp body 100 on the wire body 202 and improves the stability of the series connection of the light-emitting lamp body 100.

[0042] Specifically, two symmetrically arranged conductive springs 106 continuously provide clamping force to the wire channel 105, thereby enhancing the stability of the connection between the light-emitting lamp body 100 and the power cord 200.

[0043] Both ends of the first bracket 1021 and the second bracket 1022 have threaded connection portions 1026. The first bracket 1021 and the second bracket 1022 are spliced ​​to form a cylindrical shape. Two end caps 104 are disposed at both ends of the lampshade 101, and each end cap 104 has a through hole for threading. The end caps 104 are screwed to the threaded connection portions 1026 through threaded holes 109. By providing threaded connection portions 1026 for connecting the end caps 104, the matching splicing of the first bracket 1021 and the second bracket 1022 can be further ensured. At the same time, the two end caps 104 can limit and fix the lampshade 101.

[0044] The lampshade 101 may be cylindrical, spherical, elliptical, lantern-shaped, or polyhedral. Optionally, the lampshade 101 may be made of glass or PC material.

[0045] Furthermore, in other embodiments, depending on product style requirements, the lampshade 101 can be designed in various shapes such as spheres, ellipses, and polyhedrons with different diameters to achieve personalized customization and enrich product styles. The polyhedron shape can be a square prism, hexagonal prism, octagonal prism, etc. It should be noted that the specific shape of the light-transmitting cover is not limited to the shapes mentioned above.

[0046] The LED light-emitting unit 103 includes a flexible circuit board 1031 that surrounds the connecting bracket 102 and a plurality of LED light sources 1032 that are evenly distributed on the flexible circuit board 1031. The flexible circuit board 1031 is arranged around the outer surface of the connecting bracket 102 and is electrically connected to the connecting end.

[0047] Furthermore, the flexible circuit board 1031 also integrates LED chips, which can output corresponding control signals to adjust the luminous parameters of the LED light source 1032. These luminous parameters include output lumens, color temperature, light color, and color rendering index. By utilizing pre-set LED chips, LED light-emitting units 103 with different light source configurations can be provided, allowing for the customization of lighting fixtures with diverse styles to suit different occasions and enriching the variety of lighting products. The flexible circuit board 1031, arranged around the light source, provides a 360-degree three-dimensional light source. Due to its uniform illumination, it can provide evenly diffused light from all 360 degrees, minimizing the problem of shadows.

[0048] An insulating part 204 is formed in the middle of the wire body 202, and two conductors 201 are symmetrically snapped into the wire grooves 203 on both sides of the wire body 202. The cross-section of the wire body 202 is "I" shaped.

[0049] The wire grooves 203 provided on both sides of the wire body 202 form guide grooves for matching and holding contact ends 107, so that the light-emitting body 100 can slide freely along the wire grooves 203 and provide power to the LED light-emitting unit 103 through the contact between the conductor 201 and the holding contact end 107. The clamping of the power wire 200 by the two conductive springs 106 can ensure the stability of the power supply contact, so that the LED light-emitting unit 103 can emit light.

[0050] Preferably, the conductor 201 can be made of copper or braided wire as a conductor. The conductive spring 106 is recessed into the wire channel 105 to form a retaining contact end 107. The retaining contact end 107 has a certain elasticity and can hold the conductor 201 well, which facilitates sliding electrical connection with the energized conductor 201. This allows the series-connected light lamp body 100 to move freely along the wire groove 203 to adjust the distance and ensures stable energized contact.

[0051] In some embodiments, LED lights can be installed in various ways, such as vertically suspended, horizontally suspended, or suspended in other forms. By energizing the two conductors 201, each light lamp connected in series with the power line 200 can be lit simultaneously for use.

[0052] Four conductive springs 106 are paired and installed in the mounting grooves 1025 of the first bracket 1021 and the second bracket 1022. The first bracket 1021 and the second bracket 1022 are paired and spliced ​​to form a cylinder through the snap-fit ​​protrusions 1023 and snap-fit ​​grooves 1024 on the inner side. The LED light-emitting unit 103 is arranged around the outer side of the connecting bracket 102 so that the LED light-emitting unit 103 can emit light in 360 degrees. The connecting bracket 102 is inserted into the lamp cover 101 and threadedly connected to the threaded connection parts 1026 at both ends of the connecting bracket 102 through the two end caps 104. Thus, the assembly of the light-emitting lamp body 100 can be completed. Its overall assembly structure is simpler, reducing production and manufacturing costs and improving assembly efficiency.

[0053] The specific difference between this embodiment and the prior art lies in the following: the wire body 202 is "I"-shaped, with wire grooves 203 formed on both sides for mounting conductors 201. The wire grooves 203 extend through the axial direction of the wire body 202, and the two sides of the wire grooves 203 are bent to form protrusions. The light-emitting lamp body 100 is connected in series with the power line 200 through the wire passage 105. The light-emitting lamp body 100 and the power line 200 enable the LED lamp to be modularized, allowing users to freely combine and connect them as needed, increasing the flexibility and adaptability of use. The wire grooves 203 on both sides of the wire body 202 are designed for pairing and mounting conductors 201, and the design of the wire grooves 203 also forms grooves for pairing and holding the contact ends 107. The pairing of the contact ends 107 and the wire grooves 203 is achieved through this process. The light-emitting lamp body 100 can slide freely along the axial extension direction of the wire groove 203. With the pairing of the clamping contact end 107 and the wire groove 203, it can limit the radial rotation of the light-emitting lamp body 100, improve the stable connection between the light-emitting lamp body 100 and the power line 200. The light-emitting lamp body 100 slides along the axial direction of the power line 200 through the wire passage 105, and is wedge-locked by the clamping contact ends 107 of the two symmetrical conductive spring pieces 106 on the left and right sides with the conductors 201 on both sides of the wire body 202. This allows the light-emitting lamp bodies 100 to be flexibly and firmly connected in series. Users can easily increase or decrease the number of bulbs as needed, while ensuring that each light-emitting lamp body can work stably. It has the advantages of being able to freely combine and splice light-emitting lamp bodies of any length, having diverse product styles, and simple structure.

[0054] It should be noted that in certain applications, the number of light-emitting lamps 100 connected in series can be reasonably selected according to the desired lighting effect, so as to form a combination lamp of appropriate length. The wire 202 can be made of rigid or flexible material, which can realize the bending, specific shape and other styling and installation of the combination lamp.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
