DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0016] Referring to Figure 1, an illuminous sole 10 made in accordance with the present invention includes a sole body 20, and an electronic device 30.
[0017] The sole body 20 includes a left side 21, a right side 22, a front portion 23 and a rear portion 24. A left recess 212 pointing toward the right side 22 is defined on the left side 21, and a front-left portion 214 is arranged between the left recess 212 and the front portion 23. A rear-left portion 216 is arranged between the left recess 212 and the rear portion 24. A right recess 222 pointing toward the left side 21 is defined on the right side 22, and a front-right portion 224 is arranged between the right recess 222 and the front portion 23. A rear-right portion 226 is arranged between the right recess 222 and the rear portion 24.
[0018] The sole body 20 defines a compartment 25 located between the rear-left portion 216 and the rear-right portion 226, and includes a transparent portion 26 surrounding the compartment 25. As shown in Figure 2, in the current embodiment, the sole body 20 includes an opaque bottom 27, and the transparent portion 26 is made from transparent plastic material, and then attached to the opaque bottom 27 by means of glue or the equivalent. It should be readily appreciated that the sole body 20 can also be integrally formed with a transparent material.
[0019] Referring further to Figures 1, and 3∼5, the transparent portion 26 has an external side 262 and an internal side 264. The internal side 264 includes an inner edge 264a, and a plurality of reflecting surfaces 264b located between the inner edge 264a and the external side 262. The transparent portion 26 further defines four cells 264c extending from the inner edge 264a toward the external side 262. The reflecting surfaces 264b are adjoining with each other, and extending from the rear-left side 216 to the rear portion 24 and the rear-right side 226 of the sole body 20. Every two adjacent reflecting surfaces 264b jointly defines an obtuse angle θ.
[0020] Referring to Figures 1 and 4, the electronic device 30 includes a box 32 with a battery and a controlling circuit (not disclosed in Figures) installed therein. The electronic device 30 includes four first light emitting devices 34 extending out of the box 32. The electronic device 30 further includes four second light emitting devices 36 terminated to electrical wires extending out of the box 32. The box 32 is securely disposed within the compartment 25 located in the inner edge 264a of the transparent portion 26 of the sole body 20. The plurality of first light emitting devices 34 are securely disposed within the corresponding cells 264c, and therefore properly disposed in the rear-left side 216, the rear-right side 226, and the rear portion 24 of the sole body 20. As shown in Figures 4 and 6, the second light emitting devices 36 are disposed in the front-left side 214 and the front-right side 224 of the sole body 20.
[0021] When the electronic device 30 is powered on, the first and second light emitting devices 34, 36 will start to emit lights from illuminous sole 10's different positions. According to preferred embodiments, the first and second light emitting devices 34, 36 can be implemented with LED (light emitting diode) of different colors, such as red, green, blue and white. With this arrangement, a colorful visual effect can be reached.
[0022] Most importantly, since the internal side 264 of the transparent portion 26 of the sole body 20 is defined with reflecting surfaces 264b, and the light beam from the first light-emitting device 34 will be redirected by the reflecting surfaces 264b firstly, and then emits out of the transparent portion 26 through the external side 262. As compared to the direct or straightforward projection, the reflected or redirected light beam of the first light emitting device 34 will create a winder range of illumination after reflection. In addition, the light beams from the first and second light emitting devices 34 and 36 will intertwined with each other so as to create a brighter illumination effect after the directions of light beams are changed, i.e. without increasing the quantity of the first and second light emitting devices 34 and 36 as well as the power consumption, a brighter range and scope of illumination of the illuminous sole 10 can be reached.
[0023] It should be noted that the compartment 25, the transparent portion 26, and the first light emitting device 34 of the illuminous sole 10 are arranged adjacent to a heel of a user. However, this implementation should not be construed as a limitation, but an illustration, i.e. that they can be arranged in any suitable position of the luminous sole 10. In addition, the quantity and style of the first and second light emitting devices 34 and 36 can also be modified according to actual requirements. Since the transparent portion 26 is defined with the reflecting surfaces 264b with which the light beam from the first emitting device 34 can be redirected, and the installation of the second light-emitting device 36 can be also omitted.
