Description

Technical Field

[0001] This utility model relates to the field of LED strip technology, specifically to an LED strip that can be cut to any length. Background Technology

[0002] LED strips can be formed by soldering several LEDs onto a flexible circuit board or a rigid PCB. The LED strips are also pre-set with several cutting points, which make it easy to cut the length of the LED strips according to your needs.

[0003] In related technologies, a search revealed a novel LED light strip (announcement number CN220169386U) that includes a flexible circuit board and a flexible adhesive layer covering the flexible circuit board. The flexible circuit board includes several circuit board units, with shearing lines between adjacent circuit board units. Connecting conductors that can electrically connect the circuit board units are provided at the shearing lines. The connecting conductors include a positive conductor and a negative conductor. Each circuit board unit has a positive conductor and a negative conductor at both ends.

[0004] However, in the above scheme, the positive and negative conductors are connected by soldering when connecting the wires. For some narrow light strips, thinner wires are usually used. During soldering, the contact area between the positive and negative conductors and the solder is limited, and the stability of the solder wrapping the wire is insufficient. When the light strip and the wire are pulled, the wire can easily break from the solder joint, resulting in poor contact and affecting the power supply of the light strip. Utility Model Content

[0005] The purpose of this invention is to provide a light strip that can be cut to any length, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a light strip that can be cut arbitrarily, comprising a circuit board, on which a plurality of LED beads are soldered, and the plurality of LED beads are connected in parallel with the circuit board, ensuring that the LED beads can be used normally after the circuit board is cut arbitrarily;

[0007] A driver is electrically connected to several LED beads, and the LED beads are connected in parallel to form a lamp group. Several drivers are provided and connected in parallel. Each driver supplies power to a group of lamp groups to ensure uniform brightness of the LED beads.

[0008] The connector is located on the circuit board and is arranged alternately with the LED beads. The connector has a wiring hole and a baffle is provided inside the wiring hole.

[0009] The parallel connection of LED chips ensures that the failure of a single LED chip does not affect the overall lighting; multiple parallel drivers supply power to the lamp group, improving power supply stability and the flexibility of segmented control of the light strip; the terminals and LED chips are arranged alternately, and with the wiring holes with baffles, the light strip can be lit and used after being cut at will.

[0010] Furthermore, the LED beads include warm light LED beads and cool light LED beads, which enriches the lighting effect of the light strip. Users can select or combine different light colors according to scene requirements, such as environmental atmosphere, thereby improving the applicability and user experience of the light strip.

[0011] Furthermore, the circuit board integrates two power supply lines, which are electrically connected to the LED beads and the connectors. Integrating the power supply lines simplifies the wiring structure of the circuit board and reduces the risk of circuit failure. At the same time, it ensures that the power supply lines can stably provide power to the LED beads and achieve effective current conduction through the connectors, ensuring that each segment of the LED strip can still be powered normally after being cut.

[0012] Furthermore, the connector includes a positive terminal connecting piece and a negative terminal connecting piece, which are arranged in a racetrack shape. The positive and negative terminals are marked on the surface of the circuit board, and the structure of the connector is clearly defined to avoid confusion between the positive and negative terminals during wiring. The racetrack-shaped design increases the contact area of ​​the connecting pieces, improves the current conduction efficiency, and makes wiring operations more convenient, ensuring the stability of the connection.

[0013] Furthermore, several fixing strips are connected between the baffle and the wiring hole. The fixing strips enhance the connection strength between the baffle and the wiring hole. For wiring heads that do not require wiring, the baffle can be prevented from falling off during wiring or use, thus ensuring the structural stability of the circuit board.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) By cutting the positive and negative connecting pieces on the circuit board, the positive and negative connecting pieces can be divided into two parts. At this time, a screwdriver can be used to hold the baffle. After the fixing strip is broken, the baffle can be removed smoothly. At this time, wiring holes are formed on the positive and negative connecting pieces. After stripping the wire, insert it into the wiring hole. Then, solder the wire to the circuit board by soldering to ensure the stability of the connection. For some narrow light strips and thin wires, the problem of poor contact can be significantly reduced.

[0016] (2) Two integrated power supply lines are used to form a stable electrical connection with the lamp beads and the connector. Multiple parallel drivers are used to independently power each segment of the lamp strip, which improves the power supply flexibility of the lamp strip. The parallel driver design ensures that the power supply of each lamp group does not interfere with each other. The failure of a single driver will not affect the operation of other lamp groups, thus improving the overall power supply stability. The integrated power supply line simplifies the current conduction path and ensures that after the lamp strip is cut at will, each segment of the lamp strip can still form an effective circuit with the power supply line through the connector, ensuring that the power is continuously and stably transmitted to the lamp beads. This not only meets the need for flexible adjustment of the lamp strip length, but also avoids the problem of local failure caused by power supply interruption. After cutting, each segment of the lamp strip can be powered normally and emit light stably. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figure 1-3 This utility model provides a technical solution: a light strip that can be cut at will, including a circuit board 1, on which a plurality of lamp beads are soldered, and the plurality of lamp beads are connected in parallel with the circuit board 1. When a single lamp bead fails, it does not affect the normal operation of other lamp beads, thus ensuring the overall lighting effect of the light strip. The circuit board 1 serves as the basic carrier of the light strip, providing physical support for the installation and connection of the lamp beads, the driver U1 and the connector. The circuit board 1 can be a flexible circuit board 1 or an aluminum substrate. Adhesive can be provided on the back of the circuit board 1 to facilitate the bonding of the circuit board 1 to the lamp.

[0024] Driver U1 is electrically connected to several LED beads, which are connected in parallel to form a lamp group. Driver U1 can withstand a voltage input of 3 to 48V, which has a wide voltage range to prevent driver U1 from burning out. A constant current power supply is used to power driver U1 to ensure stable operation of the light strip.

[0025] like Figure 3 As shown, several drivers U1 are set and connected in parallel. Each driver U1 supplies power to a group of lamps. The driver U1 provides a stable power supply to the lamp beads to ensure that the lamp beads can light up normally. Several drivers U1 are connected in parallel and each supplies power to a group of lamps, which can realize independent control of different lamp groups and help to ensure uniform brightness of lamp beads in each lamp group.

[0026] The connector is located on the circuit board 1 and is arranged alternately with the LED beads. The connector has a wiring hole 8 and a baffle 7 inside the wiring hole 8. After the LED strip is cut, the connector is used to connect different segments of the LED strip. The LED strip can also be connected to the wire.

[0027] The connectors and LED chips are arranged alternately, which facilitates the cutting of the LED strip and ensures that it can still be effectively connected through the connectors after cutting.

[0028] In this embodiment, the lamp beads include warm light lamp beads 5 and cool light lamp beads 4. The warm light lamp beads 5 emit warm and soft light, while the cool light lamp beads 4 emit bright and refreshing light. The lamp beads can be soldered on the circuit board 1 as needed to meet the lighting needs of different scenarios.

[0029] In this embodiment, as Figure 2 As shown, the circuit board 1 integrates two power supply lines 6, which are electrically connected to the LED beads and connectors, transmitting power from the power supply or driver U1 to the LED beads and connectors, providing power support for the operation of the entire LED strip. The wiring structure of the circuit board 1 is simple and will not affect the cutting of the LED strip.

[0030] In this embodiment, as Figure 2 As shown, the connector includes a positive terminal connecting piece 2 and a negative terminal connecting piece 3. The positive terminal connecting piece 2 and the negative terminal connecting piece 3 are arranged in a racetrack shape. The positive terminal connecting piece 2 and the negative terminal connecting piece 3 are cut from the middle. Both the left and right parts of the positive terminal connecting piece 2 and the negative terminal connecting piece 3 can be smoothly connected to the wire. The racetrack-shaped positive terminal connecting piece 2 and the negative terminal connecting piece 3 have wiring holes 8 after being cut, which increases the contact area, improves the current conduction efficiency, and facilitates wiring operations.

[0031] In this embodiment, as Figure 2 As shown, positive and negative markings are set on circuit board 1. When using wires to connect to the positive terminal connector 2 and the negative terminal connector 3, the positive and negative terminals should be avoided to prevent the light strip from being damaged.

[0032] In this embodiment, as Figure 2 As shown, several fixing strips 9 connect the baffle 7 and the wiring hole 8. The baffle 7, wiring hole 8, and fixing strips 9 can be formed by drilling holes in the circuit board 1. The wiring hole 8 located in the middle of the light strip is generally not connected to the wire. At this time, the fixing strips 9 connect the baffle 7 and the wiring hole 8, which can improve the tensile strength of the light strip and prevent the light strip from breaking.

[0033] Specifically, when using the LED strip, cut the circuit board 1 between the positive electrode connecting piece 2 and the negative electrode connecting piece 3. The circuit board 1 has a scissor symbol to help guide the user to the cutting position.

[0034] After the circuit board 1 is cut, the positive electrode connecting piece 2 is divided into two parts, and the negative electrode connecting piece 3 is also divided into two parts. Both the positive electrode connecting piece 2 and the negative electrode connecting piece 3 have a baffle 7. Use a screwdriver or other thin tool to hold the baffle 7, and the baffle 7 pulls the fixing strip 9. When the fixing strip 9 is broken, the baffle 7 can be removed smoothly.

[0035] Next, strip the wires and insert them into the wiring hole 8. Use a soldering iron to apply a certain amount of liquid solder to the wiring hole 8. Use the liquid solder to connect the wires and the wiring hole 8. After the liquid solder solidifies, it has a high connection strength with the circuit board 1, and it is not easy for the wires to break off from the circuit board 1.

[0036] like Figure 3 As shown, driver U1 is the positive terminal of the light strip. The light strip is set in three sections, each section has 5 LEDs, the 5 LEDs are connected in parallel, the three sections of the light strip are connected in parallel, and the three drivers U1 are also connected in parallel. The negative terminal is connected in parallel at the bottom of each section of the light strip. A constant current power supply is used to power the drivers U1 and the light strip.

[0037] Failure of any driver U1, LED, or light strip will not cause the circuit to break or seriously affect the normal operation of the light strip.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
