Golf, which was generally regarded only as a part of the past, was gradually becoming one of the most popular sports in the 30s and 40s due to the increase in income and leisure time as well as the general awareness of health and sports in recent years. I'm taking it.

However, because golf is a sport played on a large outdoor field, the playing field is extremely limited to daytime due to the basic characteristics of the stadium. That is, the current golf game is only available for 13-15 hours a day, and it is almost impossible to play for 9-11 hours after sunset.

However, during the daytime when golf is possible, the general public must work at the workplace, so the public can only play golf on weekends or early morning, but in reality it is almost impossible to make reservations on weekends. Time is also very unlikely due to limitations in the distance of the golf course.

Therefore, various methods have recently been prepared to overcome such limitations, one of which is Korean Patent Application Publication No. 2005-1236 "Luminous Photoluminescent Golf Ball".

Here, the cover layer 3 or the transparent paint layer 4 is characterized in that the light-emitting layer contains an encapsulated photoluminescent composition.

These photoluminescent golf balls, unlike conventional golf balls, can shine on their own, helping to find golf balls that fly away on cloudy days, at night, or in foggy days.

However, since the photoluminescent golf ball uses light emitted from the photoluminescent composition applied to the surface of the outer layer, it is not efficient because the light emitting degree is not large, and the photoluminescent composition on the surface of the golf ball is rubbed off by friction with the club face. The disadvantage is that the efficiency is less and less.

The present invention has been made to solve the above problems, inserting a light emitting body that emits light by the battery inside the golf ball, the user to produce a transparent or semi-transparent outer shell of the light emitting body by injection molding method It is an object of the present invention to provide a luminescent golf ball that can emit light for a certain time from the moment of hitting.

In addition, an object of the present invention is to provide a light emitting golf ball that is able to determine the appropriate light emitting time as needed by embedding an IC chip that can freely control the light emission duration.

In addition, an object of the present invention is to provide a light-emitting golf ball to form a light emitting body of the urethane foam to increase the buoyancy of the golf ball so that the golf ball falling in the hazard to the water surface.

The case is characterized in that the production of urethane foam.

Hereinafter, a light emitting golf ball 10 (hereinafter referred to as a golf ball) according to an embodiment of the present invention will be described with reference to the drawings.

In general, golf balls are generally divided into one piece, two piece, and three piece according to their structure. The one-piece ball is composed entirely of a composite high elastic material of rubber and resin, the two-piece ball has a dual structure of synthetic rubber and reinforced surface part, and the three-piece ball has a core of double structure by winding a rubber thread in the central part of the ball. In addition, the outer surface is covered.

The illuminant of the present invention may be applied to both two-piece balls or three-piece balls, and for the convenience of description, the description will be made based on the two-piece ball.

Therefore, it is possible to obtain an effect such as light coming from the entire surface of the golf ball 10 rather than a specific position.

The light emitter 100 may be made of a spherical or cuboid, preferably made of a foamed urethane or synthetic rubber material to protect the impact from the outside.

In particular, when the light emitting body 100 is made of a foamed urethane material, buoyancy becomes much larger, so that even if the golf ball 10 falls into the hazard, the golf ball 10 can be easily recovered to float on the water.

Even if the light emitting body 100 is made of a foamed urethane material, by adjusting the material of the outer shell 150 and the material of the inner component of the light emitting body 100, the weight or density can be matched with a conventional golf ball, so that users feel the same.
