Description

Technical Field

[0001] This utility model relates to the field of LED light strip technology, and in particular to a novel flexible LED light strip. Background Technology

[0002] LED flexible light strips are LED light panels that can be bent and formed into various shapes, suitable for a wide range of decorative and lighting applications. Currently, co-extrusion and tubing processes are mainly used to produce LED flexible light strips. The co-extrusion process involves first connecting the flexible light panels into a single strip, then extruding it using an extruder. After forming, it is cut to different lengths, wires are bonded, and the ends are sealed to obtain the flexible light strip.

[0003] A search revealed that Chinese utility model patent application CN202222331672.3 discloses a flexible LED light strip comprising: a light strip body and an encapsulation layer. The light strip body includes a conductor group and LED beads disposed on and electrically connected to the conductor group. An encapsulating body is disposed on the outside of the LED beads, covering the LED beads and the connection point between the LED beads and the conductor group. The encapsulation layer wraps around the light strip body. The encapsulation body protects the LED beads and the connection point between the LED beads and the conductor group, making it less likely for the light strip to be affected when bent, resulting in high reliability. Furthermore, by wrapping the light strip body with the encapsulation layer and then wrapping the LED beads with the encapsulation layer, the light strip has good sealing performance, making it convenient for outdoor use. The encapsulation structure is also relatively simple, resulting in lower manufacturing costs.

[0004] For example, Chinese utility model patent application number CN202323147469.1 discloses an LED flexible light strip, including a substrate, a printed circuit on the back of the substrate, and a number of LED beads arranged on the front of the substrate. The pins of the LED beads are electrically connected to the printed circuit, and the LED beads are electrically connected to each other through the printed circuit. A transparent outer sheath is wrapped around the outer periphery of the substrate, and a wire is arranged inside the outer sheath. The wire is electrically connected to the printed circuit and is connected to an external power source through a connector to supply power to the LED beads. The key feature is that the LED beads are arranged in groups, and each group of LED beads is arranged in a pattern on the front of the substrate.

[0005] While the existing flexible LED light strips can meet basic usage requirements, their LED distribution is not reasonable enough, and they cannot effectively and fully utilize the space of the circuit board. As a result, they cannot arrange more LEDs in the limited space of the circuit board, and the luminous effect is not ideal. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a new type of flexible LED light strip to address the above-mentioned defects of the prior art, thereby solving the problems of unreasonable distribution of LED beads, inability to effectively and fully utilize the space of the circuit board, and unsatisfactory light emission effect in existing flexible LED light strips.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] A novel flexible LED light strip includes an FPC substrate. The FPC substrate has a plurality of first LED chip pads, second LED chip pads, and chip hybrid pads. The chip hybrid pads are electrically connected to the first and second LED chip pads, respectively. First LED chips and second LED chips are soldered onto the first and second LED chip pads. A constant current chip and a third LED chip are soldered onto the chip hybrid pads. The first LED chip pads, second LED chip pads, and chip hybrid pads are arranged alternately from left to right on the FPC substrate.

[0009] Preferably, the chip hybrid pad includes an upper chip hybrid pad and a lower chip hybrid pad arranged symmetrically vertically.

[0010] The upper chip hybrid pad and the lower chip hybrid pad are respectively soldered with a constant current chip and a third LED bead.

[0011] Preferably, the second LED lamp bead pad includes a second upper LED lamp bead pad and a second lower LED lamp bead pad arranged symmetrically on both sides, and each second upper LED lamp bead pad and the second lower LED lamp bead pad are respectively soldered with two second LED lamp beads.

[0012] Preferably, two first LED beads are soldered onto each first LED bead pad.

[0013] Preferably, each adjacent first LED bead, second LED bead, and constant current chip are longitudinally distributed.

[0014] Preferably, the ratio of the number of the chip hybrid pad, the first LED bead pad, and the second LED bead pad is 1:3:2.

[0015] By adopting the above technical solution, the present invention provides a novel flexible LED light strip with the following beneficial effects: The FPC substrate of the novel flexible LED light strip is provided with several first LED chip pads, second LED chip pads, and chip hybrid pads. The chip hybrid pads are electrically connected to the first and second LED chip pads respectively. First and second LED chips are soldered onto the first and second LED chip pads, and a constant current chip and a third LED chip are soldered onto the chip hybrid pad. The first, second, and chip hybrid pads are arranged alternately from left to right on the FPC substrate, resulting in a more compact overall structure and a more reasonable distribution of LEDs. This effectively and fully utilizes the space of the circuit board, thereby enabling the arrangement of more LED chips within a limited circuit board space, resulting in better luminous effect.
