First Embodiment

(17) Referring to FIG. 1 to FIG. 4, an embodiment of the present disclosure provides a luminous safety ball 1, which basically includes an inner glowing body 10 and a foam sphere 20 covering the inner glowing body 10. That is to say, the luminous safety ball 1 in this embodiment of the present disclosure is a safety ball suitable for adults and children to play with since a foam material is provided to cover the inner glowing body 10.

(18) Specifically, the inner glowing body 10 is not a perfect sphere, which can be made of a transparent or translucent elastic material. The inner glowing body 10 includes an LED light emitting module 11, such that the inner glowing body 10 can emit light through the LED light emitting module 11.

(19) Furthermore, since the inner glowing body 10 is not a perfect sphere, and the foam sphere 20 covering the inner glowing body 10 has an ununiformed thickness, the light emitted from inside the inner glowing body 10 passes through the foam sphere 20 and permeates through a surface of the foam sphere 20 to form lights with different brightness thereon. Therefore, a light transmittance of the luminous safety ball 1 can be adjusted through appropriately adjusting a thickness distribution of the foam sphere 20.

(20) Further, as shown in FIG. 4, the inner glowing body 10 has a surrounding side wall 101, and a top wall 102 and a bottom wall 103 that are disposed opposite to each other in a vertical direction and connected to the surrounding side wall 101. The thickness of the foam sphere 20 at a position corresponding to the surrounding side wall 101 of the inner glowing body 10 is relatively thinner, and the thickness of the foam sphere 20 at a position corresponding to the top wall 102 (or the bottom wall 103) of the inner glowing body 10 is relatively thicker. In other words, the thickness of the foam sphere 20 corresponding to the surrounding side wall 101 of the inner glowing body 10 is smaller than that at a position corresponding to the top wall 102 of the inner glowing body 10. In addition, the thickness of the foam sphere 20 corresponding to the surrounding side wall 101 of the inner glowing body 10 is smaller than that at a position corresponding to the bottom wall 103 of the inner glowing body 10. Therefore, the light permeating through the surface of the foam sphere 20 corresponding to the surrounding side wall 101 of the inner glowing body 10 is greater than the light permeating through the rest of the surface of the foam sphere 20.

(21) In this embodiment, a mounting portion 1021 is protrudingly formed on the top wall 102, and the mounting portion 1021 can have a threaded pattern, such that a head portion of the LED light emitting module 11 is threadedly engaged to the top wall 102 of the inner glowing body 10. An accommodating portion 1031 is protrudingly formed on the bottom wall 103, such that a tail portion of the LED light emitting module 11 is accommodated in the accommodating portion 1031 and fixed on the bottom wall 103 of the inner glowing body 10. In another embodiment, the LED light emitting module 11 can be completely hidden (i.e., encapsulated) inside the inner glowing body 10, so that it is not required to form the mounting portion 1021 and the accommodating portion 1031 on the top wall 102 and the bottom wall 103, respectively.

(22) In addition, the foam sphere 20 of this embodiment can be made of a nano-foam material. Since a diameter of pores of the nano-foam material is less than 50 nm, the light transmittance of the foam sphere 20 can be enhanced.

Second Embodiment

(23) Referring to FIG. 5 and FIG. 6, the luminous safety ball 1 further includes a cover layer 30, e.g., the skin of a baseball or a softball. In addition, the cover layer 30 can also be a light permeable layer that can partially or completely transmit light. The cover layer 30 can be covered on the surface of the foam sphere 20 as shown in FIG. 1, so as to form the luminous safety ball 1 as shown in FIG. 5.

(24) Furthermore, the cover layer 30 is formed to have at least one seam gap 31 and a plurality of stitch holes 32 positioned on both sides of the at least one seam gap 31. The stitch holes 32 are positioned corresponding to the surrounding side wall 101 of the inner glowing body 10. Since the thickness of the foam sphere 20 at the position corresponding to the surrounding side wall 101 of the inner glowing body 10 is relatively thinner, a brightness of the light that is emitted by the inner glowing body 10 and that passes through the foam sphere 20 to shine from the stitch holes 32 is at its greatest. Therefore, in this embodiment, the light having the greatest brightness can be shone from the stitch holes 32 formed on the surface of the luminous safety ball 1, such that a user can clearly recognize a movement path of the luminous safety ball 1 through the light shone from the stitch holes 32 on the surface of the luminous safety ball 1 at night or in environments with insufficient lighting.

Third Embodiment

(25) Furthermore, referring to FIG. 7, FIG. 8, FIG. 9, and FIG. 10, in order to further increase the brightness of the light emitted from the stitch holes 32, in this embodiment, the surrounding side wall 101 of the inner glowing body 10 has a groove 1011 recessed inwardly (as shown in FIG. 8). The groove 1011 can surround the surrounding side wall 101. That is to say, the groove 1011 can completely surround the surrounding side wall 101, or partially surround the surrounding side wall 101. In this embodiment, the groove 1011 partially surrounds the surrounding side wall 101. Therefore, since the groove 1011 of the surrounding side wall 101 of the inner glowing body 10 is recessed inwardly, the thickness of the foam sphere 20 corresponding to the groove 1011 of the inner glowing body 10 is slightly thicker, such that the brightness of the light exposed from the stitch holes 32 at the two sides of the groove 1011 can be further increased.

(26) In addition, an airtight state is formed inside the inner glowing body 10, so as to enhance a structural strength of the luminous safety ball 1. In other words, an airtight space A is formed inside the inner glowing body 10, such that the inner glowing body 10 can be supported and is not easily deformed. Furthermore, a wall of the groove 1011 is designed in an arc shape, which can also increase the structural strength of the luminous safety ball 1.

Fourth Embodiment

(27) As shown in FIG. 11, in order to further enhance the structural strength of the luminous safety ball 1, a support structure 104 is provided inside the inner glowing body 10, and the support structure 104 is in a shape of a honeycomb. That is to say, the support structure 104 includes a plurality of plates arranged in a honeycomb structure, so as to further enhance the inner glowing body 10 in its ability to withstand impact.

Fifth Embodiment

(28) As shown in FIG. 12, in this embodiment, a transparent waterproof protective layer 40, e.g., a waterproof adhesive film, is formed on the surface of the foam sphere 20. In this way, a strength and waterproofness of the foam sphere 20 is enhanced.

Sixth Embodiment

(29) As shown in FIG. 13, in this embodiment, a transparent coating layer 105 is coated on an inner surface of the inner glowing body 10, and a thickness of the transparent coating layer 105 can be 1 mm to 10 mm, so as to enhance the strength of the inner glowing body 10 and adjust a weight of the luminous safety ball 1.

(30) In addition, the LED light emitting module 11 disposed on the inner glowing body 10 has a battery holding part 111 and a counterweight member 112 detachably disposed in the battery holding part 111, such that the counterweight member 112 with different weights can be replaced to increase or adjust the overall weight of the luminous safety ball 1.

(31) In conclusion, in the luminous safety ball of the present disclosure includes an inner glowing body and a foam sphere covering the inner glowing body, the inner glowing body is not a perfect sphere, the foam sphere has a non-uniform thickness, and light emitted by the inner glowing body passes through the foam sphere and permeates through a surface of the foam sphere to form lights with different brightness thereon. Therefore, in the present disclosure, the thickness distribution of the foam sphere can be adjusted to adjust the light transmittance of the luminous safety ball, thereby enhancing the fun of playing with the luminous safety ball at night or in environments with insufficient lighting.

(32) The foregoing description of the exemplary embodiments of the disclosure has been presented only for the purposes of illustration and description and is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Many modifications and variations are possible in light of the above teaching.

(33) The embodiments were chosen and described in order to explain the principles of the disclosure and their practical application so as to enable others skilled in the art to utilize the disclosure and various embodiments and with various modifications as are suited to the particular use contemplated. Alternative embodiments will become apparent to those skilled in the art to which the present disclosure pertains without departing from its spirit and scope.
