Abstract

A light-emitting ping pong ball, comprising a ball body (1), multiple transparent windows (2) provided on the ball body (1), and light source lamps used for emitting light and affixed within the transparent windows (2), where the quantity of light source lamps is an even number, and any two lamps are symmetric relative to the center of the ball body (1), thus making the ping pong ball to have a uniform density and unshifting center of gravity, and allowing ping pong games in environments having poor lighting.

Description

Illuminated table tennis

[0001] The present invention relates to the technical field of sports equipment, and more particularly to illuminating table tennis.

Background technique

[0002] Table tennis is a kind of sport that our people like. There are ping-pong tables in gymnasiums, community plazas and parks for people to exercise.

[0003] In the evenings, early mornings, evenings, etc., the outdoor lighting effect is poor. When the public is playing table tennis, it is difficult to identify the faster table tennis, so that the public needs to end the exercise ahead of time, affecting the movement. In the daytime.

technical problem

[0004] An object of the present invention is to provide a luminescent table tennis ball, which aims to solve the problem that the ping-pong ball movement in the prior art is limited by illumination, and it is difficult to perform movement when the illumination is insufficient.

Problem solution

Technical solution

[0005] The present invention is achieved in that the illuminating table tennis ball includes a ball body, and the ball body is provided with a plurality of transparent windows, and each of the transparent windows is provided with a light source lamp for emitting light, and the number of the light source lamps is It is an even number, and the two are symmetric with respect to the center of the sphere.

Further, each of the light source lamps includes an LED chip that emits light of a plurality of colors.

Further, further comprising a control circuit disposed inside the sphere for controlling a manner in which each of the LED chips emits light.

Advantageous effects of the invention

Beneficial effect

Compared with the prior art, the illuminating table tennis ball in the invention can emit light through the transparent window, and the two light source lamps are symmetrical with respect to the spherical center of the sphere, so that the table tennis itself The average density does not change its center of gravity, so that it does not affect the user's movements such as cutting and smashing, so that the user can clearly recognize the position of the ball in a poor light environment and perform table tennis. Brief description of the drawing

1 is a schematic structural diagram of a luminescent table tennis ball according to an embodiment of the present invention.

BEST MODE FOR CARRYING OUT THE INVENTION

[0010] In order to make the objects, technical solutions and advantages of the present invention more clear, the following is in conjunction with the accompanying drawings and embodiments.

The present invention will be further described in detail. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0011] The implementation of this embodiment will be described in detail below with reference to the specific drawings.

[0012] As shown in FIG. 1 , in this embodiment, a illuminating table tennis ball is provided, including a ball body 1 , and a plurality of transparent windows 2 are disposed on the ball body 1 , and a light source lamp is disposed in each of the transparent windows 2 to emit light. It is convenient for the user to clearly recognize the position of the sphere 1 in a poorly illuminated environment.

[0013] The number of light source lamps is even, and the two are symmetric with respect to the center of the sphere 1, do not change the position of the center of gravity of the sphere 1, and maintain the density of the sphere 1 balanced, without affecting its axis of rotation, and making it with the original ping pong The ball has similar motion characteristics and the user can adapt quickly.

[0014] The light source lamp can be arranged in various ways, for example, by providing a colloid having a phosphor, which can emit fluorescence in the dark. The light source lamp in this embodiment includes an LED chip capable of emitting light of a plurality of colors. The LED chip itself has a small mass, has little influence on the center of gravity of the sphere 1, and can emit a plurality of color lights to enrich the user's sports experience.

[0015] A control circuit is further provided inside the sphere 1 to control the illumination mode of the LED chip. For example, if the acceleration sensor is set, it is detected that the ball 1 is subjected to the impact 吋, the color of the LED chip is switched, and the threshold value can be set to determine whether the ball 1 hits the tabletop or is hit by the racket. If it is hit, the color is switched. It is possible to judge which side of the player hits the sphere 1 based on the color to judge the score, and motivate the player to improve the exercise experience.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalents, and improvements made within the spirit and scope of the present invention should be included in the present invention. Within the scope of protection of the invention.
