Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a novel LED light string. Background Technology

[0002] The structure of an LED string light mainly consists of a main light wire and multiple light fixtures connected below it. LED strings can be strung around Christmas trees or dolls awaiting decoration, and are connected to an external power source via wire connectors. This powers the LED light-emitting elements to emit light, and the bulbs can further produce on / off lighting effects.

[0003] When assembling light strings, the main light wires and branch light wires of each light string unit are usually welded one by one by hand, and then the connection between the main light wires and branch light wires is reinforced by a T-connector.

[0004] Currently, some LED light strings on the market have built-in speaker functions, which makes the circuit of the entire light string more complex and requires more wires to be soldered manually. This not only increases the workload and reduces efficiency, but also makes it easy to make mistakes in wiring. Therefore, it is necessary to improve LED light strings. Utility Model Content

[0005] This invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, the purpose of this invention is to provide a novel LED light string with a simple structure, which improves assembly efficiency and reduces the risk of incorrect wiring.

The wires of the main light wire and the wires of the branch light wire are provided with plugs that can be inserted into the first circuit board, so that the main light wire and the branch light wire can be electrically connected through the plugs to the first circuit board.

[0008] According to the present invention, a novel LED light string is provided, which forms an electrical connection between main light wires and between main light wires and branch light wires by plugging in a first circuit board, thereby realizing the rapid connection of power lines and signal lines between light string units, improving the assembly efficiency of the light string and reducing the risk of incorrect wiring.

[0022] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] The following is for reference. Figures 1-3 The present invention will describe in detail the implementation of the novel LED light string proposed in the embodiments of the present invention.

[0025] The novel LED light string according to an embodiment of the present utility model includes:

[0026] Multiple string light units 1 are electrically connected in sequence. Each string light unit 1 includes a main light wire 11, a branch light wire 12, a three-way connector 13, a bulb mounting base 14, a speaker 15, and a first circuit board 16 with a socket 161. The outside of the main light wire 11 is connected to the outside of the branch light wire 12 through the three-way connector 13. At least one branch light wire 12 is provided with a bulb mounting base 14 and a speaker 15. The bulb mounting base 14 and the speaker 15 are connected to the main light wire 11 through the branch light wire 12. The first circuit board 16 is disposed inside the three-way connector 13. The wires of the main light wire 11 and the wires of the branch light wire 12 are provided with plugs that can be plugged into the first circuit board 16, so that the main light wire 11 and the branch light wire 12 can be electrically connected through the plugs to the first circuit board 16.

[0027] In other words, a string of lights is composed of multiple string units 1 connected together. Adjacent string units 1 are connected by a main light wire 11. Branch light wires 12 are connected to the main light wire 11 at intervals. Each branch light wire 12 has a speaker 15 for playing music and a bulb mounting bracket 14 for mounting LED lights 17. The first circuit board 16 has three sockets 161. The ends of the wires in the main light wires 11 between adjacent string units 1 and the ends of the wires in the branch light wires 12 between two adjacent main light wires 11 are crimped to terminals and inserted into the sockets of a plug. The plug connects to the sockets 161. The insertion of 61 establishes an electrical connection between the main light wires 11 and between the main light wires 11 and the branch light wires 12, thereby meeting the power and signal electrical connection requirements of the speaker 15 and the LED light 17. This greatly reduces the workload and improves assembly efficiency. At the same time, standard wire harnesses can be prefabricated to ensure the quality of the main light wire and branch light wire harnesses. Furthermore, the connection between the main light wires 11 and the branch light wires 12 is reinforced and protected by the T-connector 13, which improves the tensile strength of the light string and protects the first circuit board 16, ensuring the reliability of the electrical connection.

[0028] One of the light-supporting wires 12 can be equipped with only a bulb mounting bracket 14, or it can be equipped with both a speaker 15 and a bulb mounting bracket 14. A quick-connect connector is provided at the end of a group of light strings for connection to the controller or between different groups of light strings. The T-connector 13 can be hollow to facilitate the passage of the main light wire 11 and the light-supporting wire 12, and at the same time facilitates the placement of the first circuit board 16 inside the T-connector 13. The T-connector 13 can be connected to the outer insulation layer of the main light wire 11 and the light-supporting wire 12 by injection molding or snap-fit, thereby improving the tensile strength of the main light wire 11 and the light-supporting wire 12.

[0029] Thus, the main light wire 11 and the branch light wire 12 are electrically connected through the insertion of the first circuit board 16, realizing the rapid connection of power lines and signal lines between the light string units 1, improving the assembly efficiency of the light string and reducing the risk of incorrect wiring.

[0030] Optionally, the T-shaped connector 13 is T-shaped, with its lower end connected to the speaker 15. The lamp support wire 12 protrudes from the bottom of the speaker 15 and connects to the bulb mounting base 14. Understandably, connecting the lower end of the T-shaped connector 13 to the speaker 15 creates a relatively fixed connection between the speaker 15 and the T-shaped connector 13, thereby increasing the connection strength between them. The exposed lamp support wire 12 between the speaker 15 and the bulb mounting base 14 allows the bulb to swing more flexibly, improving the flexibility of the light string arrangement. The speaker 15 has mounting holes, and the lower end of the T-shaped connector 13 enters these holes. The speaker 15 can be connected to the lower end of the T-shaped connector 13 in a mating manner. Alternatively, after the first circuit board 16 is inserted and the internal wiring of the speaker 15 is completed, the T-shaped connector 13 can be injection molded and connected to the top of the speaker 15.

[0031] Optionally, the speaker 15 includes a first half-shell 151 and a second half-shell 152, which are connected by snap-fit ​​or screws. Understandably, the first half-shell 151 and the second half-shell 152 facilitate the connection between the internal components of the speaker 15 and the lamp holder wire 12, and also facilitate the mating connection of the lower end of the three-way connector 13, thus improving assembly efficiency. The connections between the first half-shell 151 and the second half-shell 152, between the speaker 15 and the three-way connector 13, and between the speaker 15 and the protruding portion of the lamp holder wire 12 can all be sealed to improve the waterproof rating of the speaker 15.

[0032] Optionally, the speaker enclosure 15 has a plurality of sound transmission holes 153 on its side wall. The surface where the sound transmission holes 153 are located is recessed to form a water-retaining eave 154 on the outer periphery of the sound transmission holes 153. Understandably, the recessed side wall where the sound transmission holes 153 are located makes the side wall of the speaker enclosure 15 have an uneven shape, with the protruding part forming the water-retaining eave 154. This reduces the amount of rainwater entering the sound transmission holes 153 during rainy weather, thus reducing the impact of rainwater on the sound emitted by the speaker enclosure 15. The sound transmission holes 153 can be arranged in a circular array, and the recessed area can be in an inverted U-shape.

[0033] Optionally, the tee connector 13 is also provided with a fixing hole 131 for suspension. Understandably, the fixing hole 131 facilitates the flexibility of the light string arrangement, allowing for the fixing and support of the entire light string and preventing damage to the main light wire 11 and the branch light wire 12 due to pulling. The mounting hole can be located at the center of the top of the tee connector 13.

[0034] Optionally, the tee connector 13 is connected to the main light wire 11 and the branch light wire 12 by injection molding. Understandably, injection molding simplifies the assembly process, improves the connection strength between the tee connector 13 and the main light wire 11 and the branch light wire 12, and also improves the waterproof performance at this point.

[0035] Optionally, the system also includes a second circuit board. The lamp support wire 12 from the bulb mounting bracket 14 to the speaker 15, and the lamp support wire 12 between the speaker 15 and the first circuit board 16 are electrically connected via a connection to the second circuit board. Understandably, the second circuit board facilitates the electrical connection between the lamp support wire 12 from the bulb mounting bracket 14 to the speaker 15 and the lamp support wire 12 between the speaker 15 and the first circuit board 16, improving the connection efficiency between the lamp support wire 12 and the speaker 15, and between the lamp support wire 12 and the bulb mounting bracket 14, reducing the possibility of incorrect wiring, and also facilitating the replacement of damaged parts. The second circuit board can adopt the same structure as the first circuit board 16.
