Description

Technical Field

[0001] This utility model relates to the field of flexible light strip technology, specifically a flexible light base strip. Background Technology

[0002] Flexible LED strips can be bent flexibly and can be installed using adhesive methods. Their flexibility and ease of installation make them a mainstream choice for modern decorative lighting. Currently, most flexible LED strips consist of a base strip, LED chips, and resistors. The resistors are connected to the base strip by soldering. This method of connecting the resistors can lead to poor soldering when the LED strip is bent, causing intermittent circuit continuity and resulting in the LED strip partially or completely failing to light up. Utility Model Content

[0003] The purpose of this invention is to provide a flexible lamp base strip to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flexible lamp baseband, comprising a baseband, the surface of which has a plurality of resistive regions;

[0005] A resistor, which is formed and connected to the resistive area by printing or dispensing, replaces a traditional resistor and can reduce raw material costs;

[0006] The lamp beads are arranged in multiples and alternately with resistors. The lamp beads are soldered to the baseband and protected by resistors, which can reduce the failure rate of the lamp beads.

[0007] Furthermore, the resistor is a silver paste resistor or a carbon paste resistor. Silver paste resistors have extremely low resistivity, can stably transmit large currents, support screen printing, and are easy to connect to the baseband. Carbon paste resistors are low in cost and can be quickly formed through printing processes, facilitating the production of LED strips.

[0008] Furthermore, the baseband includes a substrate layer, a conductive layer, and a cover film layer. The layered structure achieves a balance between local high flexibility (such as the folded area) and high strength (such as the display area). The cover film layer has conductive areas, which facilitate the installation of resistors and LED chips.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] (1) The material is processed onto the baseband to form a resistor by printing or dotting, which solves the problem of poor soldering of traditional welding resistors and can improve the safety performance of the lamp strip.

[0011] (2) The process of forming resistors by printing or dotting is simple, the appearance of the light strip is more beautiful, and the flexibility of the light strip can also be improved.

[0012] (3) Replacing traditional resistors with silver paste resistors or carbon paste resistors can reduce the production cost of LED strips. Attached Figure Description

[0019] 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.

[0020] Example:

[0021] Please see Figure 1-5 The present invention provides a technical solution: a flexible lamp baseband, comprising a baseband 1, wherein the surface of the baseband 1 has a plurality of resistor regions 2;

[0022] Resistor 2, which is formed and connected to the resistor 2 area by printing or dispensing, allows the printed / dispensed resistor 2 to precisely regulate the current, avoid damage to the LED bead 3 due to overcurrent, and improve circuit reliability. The printing / dispensing process can directly form the resistor 2 on the baseband 1, reducing the traditional surface mount process and lowering costs.

[0023] The lamp beads 3 are arranged in multiples and interleaved with the resistors 2. The lamp beads 3 are welded to the baseband 1. The interleaved arrangement of the resistors 2 and the lamp beads 3 avoids heat concentration and extends the life of the lamp strip.

[0024] In this embodiment, the resistor 2 is a silver paste resistor 2, which can be formed by printing or dotting. The silver paste resistor 2 is produced by screen printing the silver paste onto a designated area of ​​the baseband 1.

[0025] The silver paste is precisely deposited using dispensing equipment, which is suitable for the molding of high-precision resistors 2. The thickness of the silver paste can be controlled (e.g., 8-18μm), and the resistance value of resistor 2 can be precisely adjusted.

[0026] In this embodiment, the resistor 2 is a carbon paste resistor 2. The carbon paste is printed onto a designated area of ​​the baseband 1 through a screen template to form a resistor 2 with a width of 50-200μm.

[0027] Carbon paste is applied using high-precision dispensing equipment to form a miniature resistor.

[0028] In this embodiment, as Figure 1 and Figure 2 As shown, the LED bead 3 has a protective ring 4 on its side. The protective ring 4 is made of transparent epoxy resin or silicone, which can improve the safety of the LED bead 3.

[0029] In this embodiment, the baseband 1 includes a substrate layer, a conductive layer, and a cover film layer. The substrate layer is made of polyimide, the conductive layer is made of copper, and the cover film layer can also be made of polyimide. The conductive layer is connected to the substrate layer and the cover film layer through an adhesive layer. The cover film layer has a conductive area, and the conductive area can be provided with a resistor 2 and an LED bead 3.

[0030] Specifically, during the production of LED strips, a resistor 2 is formed in the resistor 2 area of ​​the LED strip using silver paste or carbon paste. This reduces the traditional chip mounting process for resistor 2. The silver paste or carbon paste can be processed onto the base strip 1 through screen printing or dotting, simplifying the LED strip production process and increasing production speed. The resistor 2 formed by the silver paste or carbon paste is integrated with the base strip 1, reducing the risk of failure caused by poor contact or detachment of the chip resistor 2, and improving the reliability of the LED strip. By adjusting the composition, printing thickness, and area of ​​the silver paste or carbon paste, the resistance value of 2 can be precisely controlled to meet the needs of different LED strip designs.

[0031] 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.
