FIELD OF THE DISCLOSURE

The present disclosure relates to a sphere, and more particularly to a light-emitting sphere.

BACKGROUND OF THE DISCLOSURE

In order to enable ball games, such as baseball, cricket, or lacrosse, to be played at night or in a low-light environment, certain ball products are commercially available which enable the ball to be illuminated, thereby allowing the ball to be used in a low-light environment. However, in order to replace the batteries for such products, significant changes need to be made to the structure of the ball. For example, an opening in a skin of a ball needs to be reserved to accommodate battery access for battery replacement. However, when any type of opening is formed on the ball, the characteristics and specifications of the ball can be drastically changed, thus resulting in a drastically different look and handling of the ball from that of traditional baseballs or softballs, and causes the ball to have reduced impact resistance.

EMBODIMENTS

Referring to FIG. 1 to FIG. 4, one embodiment of the present disclosure provides a light-emitting sphere 100. The light-emitting sphere 100 includes a light source device 1, a light source bracket 2, a light-transmissive housing 3, and a light-transmissive elastic layer 4.

In this embodiment, the light source device 1 can include a light-emitter 11, a power member 12, and a main controller 13, and the main controller 13 can be electrically connected to the light-emitter 11 and the power member 12.

Furthermore, the main controller can include a main control circuit board 131, and the main control circuit board 131 can have one or more microcontroller units (MCU) and resistors or capacitances provided thereon. The light-emitter 11 includes at least one light-emitting diode D. In this embodiment, the light-emitter 11 can include two light-emitting diodes D, and the two light-emitting diodes D can be disposed on an upper surface of the main control circuit board 131. Preferably, the two light-emitting diodes D are disposed on diagonal positions on the upper surface of the main control circuit board 131. The power member 12 can include at least one battery B, and the battery B can be disposed on a lower surface of the main control circuit board 131. Preferably, the battery B can be a coin cell battery (such as a CR-2032 coin-cell lithium battery). In this embodiment, the light source device 1 can further include a shaking switch 14 electrically connected to the main controller 13. The shaking switch 14 can be disposed on the upper or lower surface of the main control circuit board 131, and the shaking switch 14 can be used to sense a shaking. Furthermore, when a shaking is sensed by the shaking switch 14, the shaking switch 14 turns on each of the light-emitting diodes D, and when the shaking is not sensed by the shaking switch 14 after a predetermined period of time has elapsed, the shaking switch 14 turns off each of the light-emitting diodes D, so as to extend a usage time of the battery B. Furthermore, the main controller 13 can have a backup power supply mode, such that when one of the light-emitting diodes D is damaged, the remaining light-emitting diodes D can still emit light.

In this embodiment, the light source device 1 is fixed to the light source bracket 2, such that the light source device 1 is fixed inside the light-transmissive housing 3 through the light source bracket 2.

Furthermore, the light source bracket 2 includes an upper bracket 21 and a lower bracket 22 that are assembled to each other in a top-down manner. The upper bracket 21 has an upper body portion 211, a plurality of snap hooks 212 that extend and bend outwardly from lateral sides of the upper body portion 211, and an upper extension 213 that extends upwardly from a top surface of the upper body portion. The lower bracket 22 has a lower body portion 221, a plurality of lateral extensions 222 that extend outwardly from lateral sides of the lower body portion 221, and a lower extension 223 that extends downwardly from a bottom surface of the lower body portion 221. Moreover, an accommodating groove 2211 is recessed from a top surface of the lower body portion 221 to accommodate the light source device 1. One of a plurality of snap grooves 2221 is formed between each of the lateral extensions 222 and the lower body portion 221, such that the plurality of snap hooks 212 are correspondingly engaged to the plurality of snap grooves 2221. In addition, the upper extension 213 and the lower extension 223 are vertically disposed to be opposite to each other and respectively abut against an inner surface of the light-transmissive housing 3, thereby allowing the light source device 1 to be properly fixed inside the light-transmissive housing 3 through the light source bracket 2.

In addition, the upper extension 213 has an extension column 2131 having a cross-shaped cross-section and an arc-shaped disk. A lower end of the extension column 2131 is integrally connected to the upper body portion 211, and an upper end of the extension column 2131 is integrally connected to the arc-shaped disk 2132 to support the arc-shaped disk 2132. At least one of the light-emitting diodes D of the light-emitter 11 emits light toward the arc-shaped disk 2132, such that an arced surface of the arc-shaped disk 2132 can be used to reflect the emitted light, thereby improving an illuminance and a light-emitting area of the light-emitter 11. Moreover, light-reflective substances can be coated on the arced surface of the arc-shaped disk 2132 to further improve the reflection capability of the arc-shaped disk 2132.

In this embodiment, the light source device 1 is fixed inside the light-transmissive housing 3 through the light source bracket 2, and the light-transmissive housing 3 can completely cover the light source device and the light source bracket 2. Furthermore, the light-transmissive housing 3 is a transparent polypropylene blister package formed by vacuum-forming, and edges of a surface of the light-transmissive housing 3 are sealed by using ultrasonic waves, such that the surface of the light-transmissive housing 3 does not have any opening and an interior of the light-transmissive housing 3 is in an air-tight state. That is, an air-tight space is formed in the light-transmissive housing 3 for preventing the light-transmissive housing 3 from being easily deformed. Furthermore, light guiding powder can be uniformly dispensed on the inner surface of the light-transmissive housing 3, such that a light beam that is emitted outward from the sphere is mild and uniformly distributed.

In this embodiment, the light-transmissive elastic layer 4 is formed on an outer surface of the light-transmissive housing 3, and the light-transmissive elastic layer 4 is an elastomer formed by injection-molding an elastic plastic material. Furthermore, the light-transmissive elastic layer 4 can be formed on the outer surface of the light-transmissive housing 3 by injection-molding melted thermoplastic polyurethane (TPU). In detail, granular TPU is heated to a melting temperature, and the melted granular TPU is injected into a mold in which the light-transmissive housing 3 is located, so as to form the light-transmissive elastic layer 4 on the outer surface of the light-transmissive housing 3 by injection-molding. In addition, a material of the light-transmissive elastic layer 4 may also be polyurethane (PU), such as a PU foaming agent, or a PU foaming adhesive. Furthermore, a diameter of the light-transmissive housing 3 is preferably 6 cm, and the light-transmissive housing 3 may also have a diameter that is similar to a diameter of a ball body of a baseball or a softball, allowing a ratio of a diameter of the light-transmissive housing 3 to a thickness of the light-transmissive elastic layer 4 to be greater than or equal to 12:1, such that an improvement of the surface elasticity and shock-absorption performance of the entire sphere can be ensured.

In one embodiment, according to FIG. 5 and FIG. 6, raised patterns 41 are integrally formed on a surface of the light-transmissive elastic layer 4 of a light-emitting sphere 200. The raised patterns 41 can improve the surface elasticity and shock-absorption performance of the entire sphere by a certain degree. On the other hand, the raised patterns 41 can improve friction and slip-proof performance of the sphere to achieve a good handling experience. In this embodiment, the raised patterns 41 can be similar to a pattern of a surface of a baseball or a softball, or a pattern of a surface of other types of ball.

In one embodiment, according to FIG. 7, a light-emitting sphere 300 may further include a cover layer 5 (such as a cover skin on a baseball or a softball). In addition, the cover layer 5 can be a cover layer that is partially light-transmissive or fully light-transmissive, and the cover layer 5 can also be non-light-transmissive. Furthermore, the cover layer 5 can cover on an outer surface of a sphere as shown in FIG. 1, so as to be in a state as shown in FIG. 7. Moreover, at least one seam slit 51 and a plurality of seam holes 52 located on two sides of each seam slit 51 are formed on the cover layer 5. Therefore, light can be transmitted outward through the seam slit 51, the seam holes 52, or through the cover layer 5, such that bright light can be transmitted outward from the surface of the light-emitting sphere of the present disclosure along the seam slit 51, the seam holes 52, or through the cover layer 5, thereby facilitating the user to clearly identify a flight or moving path of the light-emitting sphere through observing the light emitted from the surface of the light-emitting sphere even in low-light or nighttime environments.

In addition, the cover layer 5 can be skins of other types of balls such as a skin of a soccer ball or a skin of a basketball, and the cover layer 5 can cover onto the surface of the ball body by adhesion. That is, the cover layer 5 can be skins of balls for various ball games such as baseball, cricket, or lacrosse, and can be produced according to different practical requirements.
