Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a battery detachable low-power LED ball marker,

The present invention relates to a battery detachable low power LED ball marker, and more particularly, to a battery detachable type low power LED ball marker which can be detached and attached to a built-in battery by using an external case and a low power integrated circuit, To a battery detachable low power LED ball marker capable of preventing the battery from being used when the battery is not used by using the dual switching method.

Recently, various kinds of accessories for golfers looking for a golf course have been developed with popularization of golf sports. In the case of a ball marker used for indicating the position of a golf ball during golf game among these golf accessories, It is becoming an important necessity.

Generally, most of these ball markers are equipped with a magnet mounted on a cap for magnetically attaching to a cap worn by a golfer, and upon putting, the ball marker is separated from the cradle and placed on the green.

However, in the case of the ball markers according to the prior art, it is made in a small size and flat shape, and it is difficult to grasp its position due to the grass when it is actually used on the green.

Particularly, it is difficult to identify the ball marker when the game is continued until dawn or late in the evening, and it is not easy to check the putting direction for putting when the distance to the hole is long.

In order to solve such a problem, an attempt has been made to attach a luminescent lamp to a ball marker to easily find a ball marker at a long distance.

However, since the ball marker with the conventional light bulb according to the related art needs to operate the switch to turn the power on and off, the case where the ball marker is used in a state in which the light emitting lamp is not lit due to concentration or inconvenience There is a problem that the battery is discharged in a short time because there are many cases where the power is turned on during the game and the battery is turned off while being switched off.

In addition, since the ball marker having the light emitting lamp is small in size, it is manufactured as a battery-integrated type, and even if the battery is discharged during use, it is difficult to replace the ball marker and power consumption is high.

Therefore, there is an urgent need for a practical and applicable technology that can extend the service life of the battery, increase its practicality because it can be easily replaced, and prevent battery usage when not in use.
