The conductive path 5 is used to ensure the uninterrupted transmission of electricity from one end to the other end of the FPC flexible board 2, ensuring the consistency and brightness of the light emission of the light strip. A wire 6 is connected to the FPC flexible board 2;

[0021] The LED light source includes LED lamp beads 1. A plurality of LED lamp beads 1 are arranged in parallel and precisely distributed on the FPC flexible board 2. The LED lamp beads 1 are fixedly connected to the FPC flexible board 2.

[0022] It should be noted that the conductive path 5 is used to ensure the uninterrupted transmission of electricity from one end to the other end of each LED lamp bead 1, ensuring that each component can obtain a constant current, thereby ensuring the stability and brightness consistency of the light emission of the light strip. At the same time, the light emitted by the closely arranged LED lamp beads 1 will overlap with each other on the light-emitting surface, forming a more uniform light distribution light source. The light is further diffused through the light-emitting surface formed between the high-transparency silicone rubber 3 and the FPC flexible board 2 to make the light uniform, performing secondary optics, making the entire light-emitting surface emit light uniformly, reducing the dark corner, and thus improving the lighting efficiency.

[0023] Furthermore, a plurality of resistors 4 are connected in series in the conductive path 5. The plurality of resistors 4 are evenly distributed between every two adjacent LED lamp beads 1. The resistors 4 are fixedly installed on the FPC flexible board 2. The resistors 4 are used to ensure that the voltage across the LED lamp beads 1 is maintained within a safe range, enabling the LED lamp beads 1 to operate within a safe working current range.

[0024] In the above embodiment, the resistor 4 ensures that each component can obtain a constant current and keeps the working current always within a safe range, improving safety.

[0025] Furthermore, a bracket is fixedly installed outside the LED lamp beads 1. The bracket is located between the high-transparency silicone rubber 3 and the FPC flexible board 2, and the bracket is fixedly connected to the FPC flexible board 2.

[0026] In the above embodiment, the LED lamp beads 1 adopt a high-density SMD1516 small-size hardening design, and the stability of the LED lamp beads 1 installed on the FPC flexible board 2 is improved through the bracket, making the light strip have the characteristics of being resistant to bending and having strong anti-bending ability, and can be used in any occasion.

[0027] Furthermore, the FPC flexible board 2 uses high-tenacity rolled copper as the base material to improve the flexibility and electrical conductivity of the FPC flexible board 2.

[0028] In the above-described embodiment, the FPC flexible board 2 uses rolled copper with high toughness as the base material, which can further improve the anti-bending ability of the light strip and ensure the stability of the light emission of the light strip at the same time.

[0030] In the above-described embodiment, the luminous efficiency of the light strip is improved to meet the customer's requirements for brightness.

[0031] Furthermore, the high-transparency silicone rubber 3 is arranged in an arc shape and welded to the FPC flexible board 2.

[0032] In the above-described embodiment, an arc-shaped light-emitting surface is formed between the high-transparency silicone rubber 3 and the FPC flexible board 2, which further diffuses the light of the light strip and can further homogenize the light.

[0033] Working principle: When this device is in use, after the light strip is installed, first connect the light strip to the power supply through the electric wire 6, and then the LED lamp beads 1 are powered on to illuminate and emit light. During the use process, the conductive path 5 ensures the uninterrupted transmission of electricity from one end to the other end of each LED lamp bead 1, ensuring that each component can obtain a constant current, guaranteeing the stability of the light emission of the light strip and the brightness consistency. At the same time, the arc-shaped light-emitting surface formed between the high-transparency silicone rubber 3 and the FPC flexible board 2 is based on the overlapping light-emitting surfaces formed by the light emitted by each LED lamp bead 1, forming a more uniform light surface distribution light source, further diffusing the light for secondary optics, homogenizing the light, making the entire light-emitting surface emit light evenly, not only reducing the dark corners, but also effectively improving the lighting efficiency.
