Description

Technical Field

[0001] The utility model relates to the technical field of LED luminous balls, in particular to an LED luminous ball that emits light evenly throughout. Background Art

[0002] Traditional ball sports, such as baseball, tennis, and golf, are difficult to play at night. Therefore, existing technologies have improved upon these traditional balls by implanting internal light-emitting components, enabling the balls to illuminate and increase the fun and possibilities of nighttime play. However, existing light-emitting balls have several drawbacks. For example, the new golf ball light-emitting device, disclosed in Publication No. CN219440606U, utilizes a snap-on design for fastening, making assembly simple. However, for balls frequently subjected to concentrated forces, this can easily lead to cracking or denting, which is difficult for users to effectively repair, shortening the overall device's service life. Furthermore, due to structural limitations, most consumer LED light-emitting ball products only achieve an 80% illumination area, resulting in uneven brightness and increased shadowing, which in turn reduces consumer comfort.

[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 4 As shown, an embodiment of the utility model discloses an LED luminous ball with overall uniform light emission, including an upper spherical shell 1 and a lower spherical shell 2. The upper spherical shell 1 and the lower spherical shell 2 are combined to form a complete hollow luminous sphere. A light source is provided inside the lower spherical shell 2, and a transparent lampshade protective shell is provided on the outside of the light source. The upper spherical shell 1 and the lower spherical shell 2 can both realize the light output of the light source, and the lower spherical shell, the light source and the transparent lampshade protective shell are connected by a connecting piece.

[0021] The upper spherical shell and the lower spherical shell are respectively provided with an upper spherical shell glue injection hole 8 and a lower spherical shell glue injection hole 9. After the sphere is assembled with hot melt glue, the total weight inside the spherical shell is adjusted by glue injection to correspond to the weight of a standard sphere.

[0022] The light source is a patch RGB LED 3, a lithium battery 7 and a light emitting diode are connected on the control chip, and a switch circuit and a charging circuit are provided on the control chip. The switch circuit is arranged between the lithium battery and the light emitting diode.

[0023] In this embodiment, the switch circuit is turned on by a touch switch and turned off by a timing circuit in the control chip.

[0024] A charging hole is provided on the lower spherical shell 2, and a power button 11 is also provided on the lower spherical shell. The power button is connected to the control chip, and the charging circuit is connected to the charging PCB board 4. The charging PCB board is arranged at the charging hole, and the power button is connected to the switch circuit. The charging hole includes a Type-C charging hole 10. The charging circuit is arranged on the PCB below the lithium battery, which can be charged by the common Type-C charging port (5V) on the market and can be used repeatedly. The LED luminous ball provided by the utility model can maintain normal use when hit with a force of 7 kilograms, and can be thrown on the water surface for normal play and use. After use, clean the water stains on the Type-C charging port and it can be charged normally. This structure can increase the viewing and entertainment value of ball sports.

[0025] The LED light ball can be lit by pressing and holding the power button (about 1 second). After lighting up, gently tapping the power button will change the color. Consumers can choose the color they like. The light ball can continuously illuminate for more than 2 hours. If the battery is too low, a small red light will light up under the ball to indicate that it needs to be charged. It can be charged by connecting a universal Type-C 5V charger. It can be fully charged in about 2 hours and 30 minutes. The small red light will automatically turn off when it is fully charged.

[0026] The exterior of the hollow luminous sphere is provided with a skin, which is adjusted according to the specific type of ball.

[0027] The transparent lampshade protective shell includes an upper transparent lampshade 5 and a lower transparent lampshade 6. The upper transparent lampshade is spherical, with its upper endpoint not exceeding the connecting surface of the lower and upper spherical shells. The connecting surface of the lower transparent lampshade and the upper transparent lampshade is cylindrical, and the bottom surface of the lower transparent lampshade is spherical, with screw holes for connectors. The internal structural design ensures that the luminous area of ​​the LED light ball reaches over 99% when in use, achieving an overall uniform lighting effect, greatly improving the user's viewing experience and entertainment.

[0028] During the assembly process of the utility model, after the PCB assembly is fixed to the lower transparent lampshade, the upper transparent lampshade is covered, and then fixed to the lower translucent ball cover, the upper ball cover and the assembled lower ball cover are heat-sealed together to form a whole that firmly wraps the lampshade. Press the power button to light up the luminous ball, and an LED on the PCB will emit light upward. The light is transmitted through the upper transparent lampshade, hits the upper ball cover and then diffuses to the lower ball cover, and finally disperses to the entire translucent ball cover to achieve a uniform lighting effect. As other optional implementation methods, uniform light guidance can be achieved by adding color powder and light diffusion powder to the ball cover during molding. After the ball cover is molded with color powder, it can effectively block the internal parts from being exposed to the line of sight. Adding light diffusion powder can achieve light guidance. The upper and lower translucent ball covers wrap the lampshade inside the column and are then heat-sealed as a whole to firmly fix it.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
