Light passes through the light entrance port into the at least one optical fiber for transmission and exits the at least one optical fiber through the plurality of light exit ports.

First, please refer to FIG. 1. FIG. 1 is a schematic view showing the application of the light-emitting device in this embodiment to the sole of an article of footwear. As shown in FIG. 1, the article of footwear 1 includes an upper 10 and a sole 12. The light-emitting device includes light-emitting units LED1 to LED2 and optical fibers FB1 to FB2. The light-emitting units LED1 to LED2 and the optical fibers FB1 to FB2 are both disposed in the sole 12 of the article of footwear 1. The optical fibers FB1 to FB2 are respectively disposed on the left and right sides of the sole 12, but are not limited thereto. The optical fiber FB1 includes an optical inlet port IN1 and a plurality of light exiting ports ND1, and the optical fiber FB2 includes an optical inlet port IN2 and a plurality of light exiting openings ND2. In fact, the light exit ND1 of the optical fiber FB1 and the light exit ND2 of the optical fiber FB2 may be the vertices of the optical fiber FB1 and the optical fiber FB2, respectively, but are not limited thereto.

The light-emitting unit LED1 is provided corresponding to the light-in port IN1 of the optical fiber FB1, and the light-emitting unit LED2 is provided corresponding to the light-in port IN2 of the optical fiber FB2. The light-emitting unit LED1 emits the light L1 to the light-in port IN1 of the optical fiber FB1, and the light L1 is transmitted into the optical fiber FB1 through the light-in port IN1, and then is emitted outside the optical fiber FB1 through the light-emitting port ND1. Similarly, the light-emitting unit LED2 emits the light L2 to the light-in port IN2 of the fiber FB2, and the light L2 is transmitted into the fiber FB2 through the light-in port IN2, and then exits the fiber FB2 through the light-emitting port ND2.

It should be noted that during the transmission of the light L1 in the optical fiber FB1, the light L1 is continuously reflected by the inner wall of the optical fiber FB1. When the light ray L1 is reflected to the position of the light exit port ND1 of the optical fiber FB1, the light ray L1 is emitted from the light exit port ND1 of the optical fiber FB1 to the outside of the optical fiber FB1, so that the sole 12 of the article of footwear 1 has an effect of emitting light. Similarly, during the transmission of the light L2 in the optical fiber FB2, the light L2 is continuously reflected by the inner wall of the optical fiber FB2. When the light ray L2 is reflected to the position of the light exit port ND2 of the optical fiber FB2, the light ray L2 is emitted from the light exit port ND2 of the optical fiber FB2 to the outside of the optical fiber FB2, so that the side of the sole 12 of the article of footwear 1 can emit light. effect.

In practical applications, the optical fibers FB1 and FB2 may be plastic optical fibers, but not limited thereto; the optical fibers FB1 and FB2 may be embedded into the sole 12 of the footwear product 1 by thermal bonding, but not limited thereto; The unit LED1 and the LED2 may be light-emitting diodes, but not limited thereto; the light-emitting units LED1 and LED2 may be driven by electric energy to respectively emit light L1 and L2, and the electric energy may be kinetic energy (for example, when the user wears the footwear 1 to walk or run) There is no specific limitation on whether the generated kinetic energy is converted or supplied from an external power source.

In addition, the light-emitting units LED1 and LED2 can adopt light-emitting units that emit visible light of different colors, for example, light-emitting diodes emitting red light (R), green light (G), and blue light (B), which are matched with each other to emit various colors. The visible light (for example, red light, violet light, etc.) is incident into the optical fibers FB1 and FB2 through the optical entrances IN1 and IN2, respectively, to emit visible light of different colors through the light exits ND1 and ND2 of the optical fibers FB1 and FB2, respectively. This is limited to this.

It should be noted that, since the light beams L1 and L2 emitted by the light-emitting units LED1 and LED2 of the present invention are not directly transmitted to the eyes, they are respectively transmitted through the optical fibers FB1 and FB2 and respectively pass through the light-emitting ports ND1 and ND2 of the optical fibers FB1 and FB2. The injection can avoid damage to the vision caused by the light emitted by the light-emitting diode (point light source) in the prior art directly to the eye.

Further, in the present invention, a fluorescent material (not shown) may be further disposed outside the light exits ND1 and ND2 of the optical fibers FB1 and FB2. When the light rays L1 and L2 are emitted from the light exits ND1 and ND2 of the optical fibers FB1 and FB2, respectively, the light rays L1 and L2 are incident on the fluorescent material, so that the fluorescent material is excited by the light rays L1 and L2 to emit softer fluorescence. Avoid damage to your vision. In fact, in the present invention, the phosphors may be disposed outside the light exits ND1 and ND2 of the optical fibers FB1 and FB2 by bonding fluorescent films or woven fluorescent wires, but are not limited thereto.

It should be noted that the positions where the light-emitting units LED1 to LED2 and the optical fibers FB1 to FB2 are disposed in the sole 22 are not limited to the above embodiments, and the most appropriate setting can be performed according to actual needs.

For example, as shown in FIG. 2, the optical fibers FB1 - FB2 may be respectively disposed in the front half and the rear half of the sole 22, instead of being disposed on the left and right sides of the sole 12 as the optical fibers FB1 - FB2 in FIG. But it is not limited to this. As for the light-emitting unit LED1 in FIG. 2, which is still disposed in the middle portion of the sole 22 corresponding to the light-in port IN1 of the optical fiber FB1, and the light-emitting unit LED2 still corresponds to the light-in port IN2 of the optical fiber FB2, it is disposed in the intermediate portion of the sole 22. Similarly, the light-emitting unit LED1 emits the light L1 to the light-in port IN1 of the optical fiber FB1, and the light L1 is transmitted into the optical fiber FB1 through the light-in port IN1, and then exits the optical fiber FB1 through the light-emitting port ND1. Similarly, the light-emitting unit LED2 emits the light L2 to the light-in port IN2 of the fiber FB2, and the light L2 is transmitted into the fiber FB2 through the light-in port IN2, and then exits the fiber FB2 through the light-emitting port ND2. Thus, the side of the sole 22 of the article of footwear will have the effect of illuminating.

In another embodiment, as shown in FIG. 3, the optical fibers FB1 - FB2 are also disposed in the front half and the rear half of the sole 22, respectively. The difference from the above embodiment is that the light-emitting unit LED1 in FIG. 3 is disposed on one side of the sole 32 corresponding to the light-in port IN1 of the optical fiber FB1 and the light-emitting unit LED2 is disposed corresponding to the light-in port IN2 of the optical fiber FB2. The other side. Similarly, the light-emitting unit LED1 emits the light L1 to the light-in port IN1 of the optical fiber FB1, and the light L1 is transmitted into the optical fiber FB1 through the light-in port IN1, and then exits the optical fiber FB1 through the light-emitting port ND1. Similarly, the light-emitting unit LED2 emits the light L2 to the light-in port IN2 of the fiber FB2, and the light L2 is transmitted into the fiber FB2 through the light-in port IN2, and then exits the fiber FB2 through the light-emitting port ND2. Thus, the side of the sole 32 of the article of footwear will have the effect of illuminating.

The plurality of vertices of the plastic optical fiber are ejected, so that the sole has a luminous effect. In addition, since the light emitted by the light-emitting unit of the present invention is not directly directed to the eye, it is even possible to emit softer fluorescence by the phosphor being excited by the light emitted from the break point of the plastic optical fiber to avoid damage to the vision.
