[0002] Light-emitting diodes are light-emitting devices that can convert electrical energy into light energy. They can emit light in a controlled manner, and multiple light-emitting diodes can be combined to present a variety of colors and lighting effects. Therefore, they have been widely used in wearable devices in recent years, and the most common application is the use of light-emitting diodes in shoes.
[0003] Light-emitting diodes are generally used in combination with decorative parts. When the decorative parts with light-emitting diodes are set on the shoes, the shoes become luminous shoes that can emit light. The decorative parts include a light-emitting layer covering the light-emitting diodes. The light-emitting diodes are located at the center of the light-emitting layer close to the shoe, and the light-emitting surface faces the center of the light-emitting layer. The light emitted by the light-emitting diodes can be projected outward through the center of the light-emitting layer. Under the control of the controller, the light-emitting diodes can present bright and dark lighting effects. This bright and dark lighting effect is particularly eye-catching when the light is weak, and it is easy to attract people's attention, especially children. Because children are shorter than adults, they are relatively closer to the light source, and because of curiosity and love, they may stare at the light source for a long time, causing eye discomfort.

The decorative part 2 is a strip-shaped block extending along a second direction B, and the decorative part 2 includes a light-shielding area 21 extending along the second direction B and a light-transmitting area 22 extending along the second direction B and adjacent to the light-shielding area 21, Figure 1 The example in which the light-transmitting area 22 is two and is disposed on both sides of the light-shielding area 21 and adjacent to the light-shielding area 21 is given. The first surface 211 (see Figure 2 ) is provided with a receiving groove 2111 (see Figure 2 As shown in the figure, the shading area 21 does not transmit light outward at least in a direction perpendicular to the first surface 211 of the shading area 21. When the light-emitting diode unit 1 is accommodated in the accommodation groove 2111, the SMD light-emitting diode 12 is located below the shading area 21 and is covered by the shading area 21. The first direction A is consistent with the second direction B, and the light emitted by the SMD light-emitting diode 12 can pass through the light-transmitting area 22. The "outside" here refers to the direction away from the light-emitting component relative to the light-emitting component.

[0023] In one embodiment, the flexible circuit board 11 is provided with a lead interface (not shown), one end of which is fixedly connected to the connecting lead. In one embodiment, the lead interface is located on a second surface (not shown) of the flexible circuit board 11 opposite to the first surface 111 of the flexible circuit board 11, thereby effectively avoiding interference with the arrangement and use of the SMD light emitting diodes 12 on the first surface 111 of the flexible circuit board 11.

In one embodiment, the SMD LEDs on both sides are arranged at intervals from each other along the first direction A, such as Figure 1 As shown, the light emitted by the multiple SMD LEDs 12 when emitting light simultaneously is softer and more uniform.

[0028] In one embodiment, the depth of the receiving groove 2111 matches the overall thickness of the LED unit 1 to ensure that when the LED unit 1 is received in the receiving groove 2111 , the LED unit 1 will not protrude from the receiving groove 2111 and be damaged.
[0029] In one embodiment, the LED unit 1 is placed in the receiving groove 2111 in a manner that the first surface 111 of the flexible circuit board 11 faces the receiving groove 2111, so that the SMD LED 12 is located between the flexible circuit board 11 and the shading area 21, which can effectively protect the SMD LED 12.

Further, in one embodiment, as Figure 2 As shown, the second surface of the light-transmitting layer 213 opposite to the first surface of the light-transmitting layer 213 protrudes in a direction away from the first surface of the light-transmitting layer 213 to form a protrusion 2131, and the light-shielding layer 212 covers the outer surface of the protrusion 2131. The light emitted by the patch light-emitting diode 12 can pass through the side surface of the protrusion 2131, which can make the light-emitting effect more three-dimensional. In one embodiment, the light-transmitting layer 213 and the light-transmitting area 22 are an integrated structure, which can improve the stability of the decorative part 2 and simplify the manufacturing process. In one embodiment, the materials used for the light-transmitting layer 213 and the light-transmitting area 22 are the same or different.

In one embodiment, the outer contour of the light-transmitting area 22 may present a pattern used to characterize the decorative portion 2.
