[0024] See also Figures 1 to 4 As shown, the present invention provides a luminous sphere 100 , which basically includes a light source device 1 , a light source bracket 2 , a light-transmitting shell 3 and a light-transmitting elastic layer 4 .

[0025] In this embodiment, the light source device 1 may include a light emitting unit 11 , a power supply unit 12 and a main control unit 13 . Moreover, the main control unit 13 is electrically connected to the light emitting unit 11 and the power supply unit 12 .

[0026] Furthermore, the main control unit 13 may include a main control circuit board 131, and the main control circuit board 131 may be provided with a single or multiple microprocessors (MCU) and components such as resistors or capacitors. The light emitting unit 11 may include at least one light emitting diode D, and the light emitting unit 11 may include two light emitting diodes D in this embodiment, and the two light emitting diodes D may be arranged on the front of the main control circuit board 131. Preferably, the two light emitting diodes D are arranged diagonally on the front of the main control circuit board 131. The power supply unit 12 may include at least one battery B, and the battery B may be arranged on the back of the main control circuit board 131. Preferably, the battery B may be, for example, a button battery (e.g., a CR-2032 coin-cell lithium battery). In this embodiment, the light source device 1 may further include a vibration switch 14 electrically connected to the main control unit 13. The vibration switch 14 can be arranged on the front or back of the main control circuit board 131, and the vibration switch 14 can be used to sense vibration, and when the vibration is sensed, the switch is turned on to control each light emitting diode D to turn on, and when the vibration is not sensed after a preset time, the switch is turned off to control each light emitting diode D to turn off, thereby extending the service life of the battery B. In addition, the main control unit 13 can also have a backup power supply mode, so that when one of the light emitting diodes D is damaged, the other light emitting diodes D will still light up.

[0027] In this embodiment, the light source device 1 is fixed to the light source bracket 2 , so that the light source device 1 is fixed inside the light-transmitting housing 3 through the light source bracket 2 .

[0028] Furthermore, the light source bracket 2 includes an upper bracket 21 and a lower bracket 22 which are assembled with each other up and down. The upper bracket 21 has an upper body portion 211, a plurality of hook portions 212 formed by bending and extending outward from the side of the upper body portion 211, and an upper extension portion 213 formed by extending upward from the top surface of the upper body portion 211. The lower bracket 22 has a lower body portion 221, a plurality of side extension portions 222 formed by extending outward from the side of the lower body portion 221, and a lower extension portion 223 extending downward from the bottom surface of the lower body portion 221. In addition, a receiving groove 2211 is concavely provided on the surface of the lower body portion 221, and the light source device 1 is received in the receiving groove 2211, and a bayonet groove 2221 is provided between each side extension portion 222 and the lower body portion 221, so that the corresponding hook portion 212 is engaged with the corresponding bayonet groove 2221. Furthermore, the upper extension portion 213 and the lower extension portion 223 are disposed opposite to each other in upper and lower directions and respectively abut against the inner surface of the light-transmitting housing 3 , so that the light source device 1 can be well fixed inside the light-transmitting housing 3 through the light source bracket 2 .

[0029] Furthermore, the upper extension portion 213 has an extension pillar 2131 with a cross-rib-shaped cross section and an arc-shaped plate 2132. The lower end of the extension pillar 2131 is integrally connected to the upper body portion 211, and the upper end of the extension pillar 2131 is integrally connected to the arc-shaped plate 2132 to support the arc-shaped plate 2132. The light-emitting diode D of the light-emitting unit 11 emits light toward the arc-shaped plate 2132, and the light can be reflected by the arc surface of the arc-shaped plate 2132 to increase the brightness and light-emitting area of ​​the light-emitting unit 11. Furthermore, the arc surface of the arc-shaped plate 2132 can also be coated with a reflective material to further enhance the reflection phenomenon.

[0030] In this embodiment, the light source device 1 is fixed inside the light-transmitting housing 3 through the light source bracket 2, and the light-transmitting housing 3 can completely cover the light source device 1 and the light source bracket 2. In addition, the light-transmitting housing 3 is a plastic blister formed by blistering of transparent polypropylene (PP) material, and the surface edge of the light-transmitting housing 3 is sealed by ultrasonic wave without any opening, so that the inside of the light-transmitting housing 3 forms an airtight state, that is, the inside of the light-transmitting housing 3 forms an airtight space, which can maintain the light-transmitting housing 3 not easy to deform. In addition, the inner surface of the light-transmitting housing 3 can be evenly distributed with light-guiding powder, so that the light transmitted is soft and evenly distributed.

[0031] In this embodiment, the light-transmitting elastic layer 4 is formed on the surface of the light-transmitting shell 3. The light-transmitting elastic layer 4 of this embodiment is an elastomer formed by injection molding of an elastic plastic material. Further, the light-transmitting elastic layer 4 of this embodiment can be formed on the surface of the light-transmitting shell 3 by injection molding of molten thermoplastic polyurethane (TPU). In detail, this embodiment uses granular TPU as a material and heats it to a melting temperature, and then injects the molten TPU particles into the light-transmitting shell 3 located in the mold, so that the light-transmitting elastic layer 4 is injection-molded on the surface of the light-transmitting shell 3. In addition, this embodiment can also use polyurethane (PU) as a material, such as PU foaming agent or foaming glue. In addition, the diameter of the light-transmitting shell 3 is preferably 6 cm, and can also have a similar diameter to the ball of a traditional hardball or softball, and the ratio of the diameter of the light-transmitting shell 3 to the layer thickness of the light-transmitting elastic layer 4 is greater than or equal to (≥) 12:1, so as to effectively enhance the surface elasticity and shock absorption performance of the entire ball.

[0032] In one embodiment, refer to Figure 5 and Figure 6 As shown, the surface of the light-transmitting elastic layer 4 of the luminous sphere 200 can be integrally formed with raised patterns 41. On the one hand, the raised patterns 41 increase the surface elasticity and shock absorption performance of the entire sphere to a certain extent, and on the other hand, the friction and anti-slip performance can be improved to achieve high grip. In this embodiment, the raised patterns 41 can be similar to the patterns on the surface of a baseball or softball, but can also be the surface patterns of other balls.

[0033] In one embodiment, refer to Figure 7 As shown, the luminous sphere 300 may also have a coating layer 5 (such as the cover of a baseball or softball). Further, the coating layer 5 may be a light-transmitting coating layer that is partially or completely light-transmitting, and the coating layer 5 does not necessarily have to be light-transmitting. Figure 1 The surface of the sphere in the Figure 7 In other words, the covering layer 5 is formed with at least one stitching gap 51 and a plurality of stitching holes 52 located on both sides of the stitching gap 51. Thus, light can be transmitted from the stitching gap 51, the stitching holes 52 or from the covering layer 5, so that the surface of the luminous sphere of the present invention can transmit bright light along the stitching gap 51, the stitching holes 52 or from the covering layer 5, so that the user can clearly find the flight or movement path of the luminous sphere from the light transmitted from the surface of the luminous sphere in low light or nighttime environments.

[0034] In addition, the coating layer 5 can also be the outer skin of other balls that are pasted on the surface of the sphere, such as the outer skin of a football or a basketball. In other words, the coating layer 5 can be the outer skin of various balls made according to different needs, such as the outer skin of a baseball, a cricket, or a lacrosse.

[0035] To summarize the above, the luminous sphere provided by the present invention can at least be effectively protected by the technical solutions of "the light source device is fixed on the light source bracket", "the light source bracket is fixed inside the light-transmitting shell", "the light-transmitting shell completely covers the light source device and the light source bracket, without any openings on the surface of the light-transmitting shell, and the interior of the light-transmitting shell is airtight", and "a light-transmitting elastic layer is formed on the surface of the light-transmitting shell", and the surface elasticity and shock absorption performance of the luminous sphere can be effectively enhanced. The biggest advantage of the structure of the present invention is that there are no relatively large cracks, so the impact resistance is very high.
