Description

Shoes with light guide design

This creation is about a shoe; specifically, the creation is about a shinable shoe.

The shoes provide protection for the user's foot. In addition to providing foot protection, it is also necessary to provide users with the effect of safe activities in different situations. For example, a user of a night running department needs a shoe with a luminous design. Most of the existing shoes with luminous design can only be partially illuminated. To increase the shine of the shoe, you need to increase the number of light sources, which will increase the overall cost. Therefore, the structure of existing shoes still needs to be improved.

One of the aims of this creation is to provide a shoe that enhances recognition.

The shoe comprises at least one light source, an optical fiber, a light guiding film, a sole layer and a body disposed on the sole layer. The light source is placed on the bottom of the shoe. The light source emits light along a first path and a second path different from the first path. The body has an upper. The fiber portion is disposed on the sole layer and extends over the upper surface. The optical fiber has a light incident end corresponding to the light source to receive light from the first path. The light guiding film is disposed on a bottom surface of the sole layer, and the light guiding film receives light from the second path.

This creation provides a shoe with a light guide design. The sole structure of the present invention can be applied to sports shoes and casual shoes, but is not limited thereto. Please refer to Figure 1. 1 is a perspective perspective view of an embodiment of the shoe 1 of the present invention.

As shown in FIG. 1, the shoe 1 includes a sole layer 10 and a body 11 disposed on the sole layer 10. In addition, the shoe 1 further includes at least one light source 30, an optical fiber 40, and a light guiding film 50 (see Fig. 2). The light source 30 is disposed on the sole layer 10. The light source can be, for example, a light emitting diode. The body 11 has an upper 13. The optical fiber 40 is partially disposed on the sole layer 10 and extends over the upper 13 . For example, a portion of the optical fiber 40 is embedded in the sole layer 10, and other portions of the optical fiber 40 are placed between the meshes of the upper 13 such that the optical fibers 40 are distributed over the upper 13. The optical fiber 40 receives the light from the light source 30. Thereby, the light emitted by the light source 30 is guided by the optical fiber 40 and transmitted to the upper 13 to form the stripe of the shoe 1. The illuminating pattern can increase the recognition in the dark place of the environment to ensure the safety of the user.

2 is a schematic view of the sole layer 10 having a light guiding film 50. As shown in FIG. 2, the shoe 1 includes a light guiding film 50. The light guiding film 50 can be, for example, a light transmissive plastic film disposed on the bottom surface 12 of the sole layer 10. The light guiding film 50 may be directly attached to the bottom surface 12, but not limited thereto, the light guiding film 50 may be embedded in the sole layer 10 such that the surface of the light guiding film 50 is flush with the bottom surface 12 of the shoe 1. In the embodiment of FIG. 2, the light directing film 50 has an annular shape distributed around the bottom surface 12 (ie, distributed along the outer side 14 of the bottom surface 12) and located between the outer side 14 and the light source 30. The light guiding film 50 receives the light emitted by the light source 30. Thereby, the light emitted by the light source 30 can be emitted from the bottom surface 12 of the shoe 1 via the light guiding film 50.

Please refer to Figure 3A for further reference. 3A is a partial enlarged cross-sectional view of one embodiment of a sole layer 10. As shown in FIG. 3A, the sole layer 10 has a light source 30, a portion of the optical fiber 40, and a light guiding film 50. The optical fiber 40 and the light guiding film 50 respectively receive the light emitted from the light emitting surface 32 of the light source 30. Specifically, the light source 30 emits light along the first path R1 and the second path R2 different from the first path R1. The optical fiber 40 has a light incident surface 42 that faces the light source 30 and receives light from the first path R1. Light entering the fiber 40 is directed to the upper via the sole layer 10.

On the other hand, the light guiding film 50 provided on the sole layer 10 receives the light from the second path R2. Light entering the light guiding film 50 is emitted from the bottom surface 12 of the shoe via the light guiding film 50. By this design, the light of the same illumination source is guided to different positions via different light guiding media (for example, the surface is emitted from the opposite direction, or a plurality of positions in which the outgoing light direction angle is greater than 90 degrees) to further increase the recognition degree. .

In the embodiment of FIG. 3A, a light diffusing medium 52 is disposed within the light directing film 50. The light entering the light guiding film 50 is modulated by the light diffusing medium 52 and then emitted from one side of the bottom surface 12. The light diffusion medium 52 may be, for example, a phosphor powder. For example, light source 30 has a first color of light. The light of the light source 30 impinges on the phosphor powder in the light guiding film 50 to generate a second color light. First color light and second color light mixing It is then emitted from one side of the bottom surface 12. The color of the light can be adjusted by changing the source 30 and the type of phosphor. In other embodiments, the light diffusing medium 52 can be a quantum dot (eg, cadmium selenide). The color of the light can be adjusted by changing the size of the quantum dot.

3B is a partial enlarged cross-sectional view of another embodiment of the sole layer 10. The difference from the embodiment illustrated in FIG. 3A is that the light directing film 50 overlaps the light source 30 projection in the direction of the vertical bottom surface 12. In other words, the light guiding film 50 can be sized according to the desired illumination effect. For example, for light that does not enter the fiber 40 (or uncoupled light), adjusting the size of the light directing film 50 can increase the contact area with uncoupled light to improve light utilization. It should be noted that, in the foregoing embodiment, the light source emitting surface is disposed on the bottom surface, but the invention is not limited thereto, and the light source is disposed to match the position of the light guiding film and the optical fiber.

4 is a schematic view of another embodiment of a shoe bottom layer having a light guiding film. In the embodiment of FIG. 4, the light guiding film 50 has a planar sheet shape and is distributed over the entire surface 12 on the bottom surface 12. The light source 30 is disposed at a side edge of the light directing film 50 (eg, near the junction of the sole layer and the side upper). The light guiding film 50 receives the light emitted by the light source 30. Thereby, the light emitted by the light source 30 can be emitted from the bottom surface 12 of the shoe 1 via the light guiding film 50.

Please refer to Figure 5 for further reference. FIG. 5 is a partially enlarged cross-sectional view showing another embodiment of the sole layer 10. As shown in FIG. 5, the light guiding film 50 is distributed over the entire surface of the bottom surface 12 of the sole layer 10, and the light source 30 is disposed at the side edge of the light guiding film 50. Part of the light from the source 30 enters the fiber 40, while uncoupled light enters the light directing film 50. The light entering the light guiding film 50 is modulated from the light diffusion medium 52 and then emitted from one side of the bottom surface 12.

Fig. 6 is a plan view showing the light emitted from the creation shoe 1. As shown in the state diagram of FIG. 6, the light emitted by the light source is guided through the optical fiber 40 and transmitted to the upper 13. As shown in the state of use diagram shown in FIG. 7 (viewed from the side of the bottom surface 12), the light guiding film 50 receives light emitted from the light source via the light guiding film 50, except that the optical fiber 40 guides the light emitted to the upper 13. Shoes The bottom surface 12 of 1 is emitted. Thereby, the light in different directions is provided to increase the recognition degree, and the number of light sources can be saved, and the manufacturing cost can be reduced.
