Description of the invention: • [Technical field to which the invention pertains] - The present invention relates to a shoe. [Prior Art] • At present, there are a wide variety of shoes on the market, and shoes with various functions such as illuminating functions have long been accepted by the public. Light Emitting Diode (LED) is widely used as a lighting element for lighting devices because of its good light quality (that is, the spectrum emitted by LED light source) and high luminous efficiency. For details, see Michael S. Shur et al. The article "Solid-State Lighting: Toward Superior Illumination" published in Proceedings of the IEEE, Vol. 93, No. 10 (October 2005). A shoe having a light-emitting function generally uses a light-emitting diode as a light-emitting device, and a battery is provided in the shoe to supply the light-emitting diode to emit light. However, the power supply battery provided in the shoe is usually a disposable battery, and when the power supply is insufficient, the power supply diode cannot be powered to emit light. The battery is used for a short period of time, and the battery needs to be replaced frequently, causing environmental pollution and causing inconvenience to the user. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a shoe that can instantly replenish electric energy and is environmentally friendly. A shoe comprising a shoe body, a sole, a light emitting diode and a power supply device. The shoe body is disposed on the sole. The light emitting diode is disposed on a side of the sole. The power supply device supplies power to the light emitting diode to emit light. The sole opens a receiving space. The power supply device 6 200950717 includes a piezoelectric material body and an electrical energy storage device. The piezoelectric material body is disposed between the shoe body and the sole. The electrical energy storage device is housed in the receiving space and electrically connected to the piezoelectric material body and the light emitting diode, respectively. Compared with the prior art, the shoe generates electric energy instantaneously under the pressure of the user walking by setting the piezoelectric material body, and the electric energy storage device stores the electric energy generated by the piezoelectric material body to supply the light emitting diode without frequent replacement. Power supply devices meet environmental requirements. [Embodiment] Hereinafter, embodiments of the present invention will be further described in detail with reference to the accompanying drawings. Please refer to FIG. 1 , which illustrates a shoe 100 according to an embodiment of the present invention. The shoe 100 includes a shoe body 10, a sole 20, a light emitting diode 40, and a power supply device 60. The shoe body 10 is disposed on the sole 20 . The light emitting diode 40 is disposed on a side of the sole 20. The power supply unit 60 supplies power to the light-emitting diodes 40 to emit light. In the present embodiment, in order to better illuminate the light-emitting diode 40 for the user, the light-emitting diode 40 is disposed at the front end of the side of the sole 20. The sole 20 is provided with a receiving space 22. It can be understood that a recess can be formed in the surface of the sole 20 to form the receiving space 22 or a recess can be formed in the interior of the sole 20 to form the receiving space 22. In the present embodiment, the accommodating space 22 is a groove formed in the surface of the sole 20. Referring to FIG. 2, the power supply device 60 includes a piezoelectric material body 62 and an electrical energy storage device 64. The piezoelectric material body 62 is disposed between the shoe body 10 and the 7200950717 sole 20 so that a pressure can be applied to the piezoelectric material body 62 when the user walks. The electrical energy storage device 64 is electrically connected to the piezoelectric material body 62 and the light-emitting diodes and the polar bodies 40, respectively. The piezoelectric material body 62 can convert mechanical energy into electrical energy. When the user walks, pressure is applied to the sole, and the piezoelectric material body 62 generates electric energy under pressure. The piezoelectric material may be one of barium titanate, lithium niobate, and a polyvinylidene fluoride material. The electric energy storage device 64 has a function of storing electric energy and outputting electric energy, that is, the electric energy storage device 64 is a device capable of storing electric energy such as a rechargeable battery or a capacitor. In the present embodiment, the electrical energy storage device 64 stores the electrical energy generated by the piezoelectric material body 62 and outputs electrical energy to the light emitting diode 40. To make better use of electrical energy, a switch 66 can be placed on the sole 20. The switch 66 is disposed between the electrical energy storage device 64 and the light emitting diode 40 and electrically connected to the electrical energy storage device 64 and the light emitting diode 40, respectively. The switch 66 is used to control whether the electrical energy storage device 64 supplies power to the light-emitting diode 40. If the switch 66 is turned on, that is, the electrical energy storage device 64 is in communication with the light emitting diode 40, the electrical energy storage device 64 supplies power to the light emitting diode 40 to cause it to emit light. If the switch 66 is off, i.e., the electrical energy storage device 64 is not in communication with the light emitting diode 40, the electrical energy storage device 64 is not powered to the light emitting diode 40. The switch 66 can be a manual push switch to facilitate the user to turn on/off as needed. To enhance the intelligent design, a detection device 68 can be provided for automatically detecting the ambient brightness to control the activation/deactivation of the switch 66. The detecting device 68 includes a sensing unit 68a and a comparing unit 68b. The comparison unit 68b is electrically connected to the switch 66. 8 200950717 The sensing unit 68a is configured to sense the brightness of the external environment to obtain an ambient luminance value. The sensing unit 68a may have a function of sensing external light, such as a photodiode or a photometer, and the like, which can sense the light intensity function. A standard luminance value is preset in the comparison unit 68b. The comparing unit 68b is for comparing the ambient luminance acquired by the sensing unit 68a with the standard luminance to determine whether to turn on/off the switch 66. If the ambient luminance value is less than the standard luminance value, the comparing unit 68b controls the switch 66 to be turned on, and the electrical energy storage device ❹64 supplies the stored electrical energy to the light-emitting diode 4 to cause the light to be illuminated by the user. If the ambient luminance is greater than or equal to the standard luminance value, the comparison unit * 68b control switch 66 is turned off, and the electrical energy storage device 64 does not supply power to the light emitting diode 40. The shoe 100 generates electric energy instantaneously by setting the piezoelectric material body 62 under the pressure of the user walking, and the electric energy storage device 64 stores the piezoelectric material body=the raw electric energy to supply the light-emitting diode 4G without frequent replacement. For g electric devices, to meet environmental requirements.
