The present invention has been made to solve the above problems of the prior art, by improving the series of LED structure to be installed on the frame to the point light source structure that can be detachably assembled separately to ensure stability, easy installation and maintenance The purpose of the present invention is to provide a detachable LED lighting module device with improved handling efficiency, such as allowing a user to easily install and use even a user who does not have professional knowledge.

Another object of the present invention is to facilitate the replacement and repair of only the damaged LED even if a partial LED damage occurs among the plurality of LEDs installed in the frame according to the point light source structure capable of detachable assembly of the LED, functionality and efficiency of use It is to provide a removable LED lighting module device that can improve the.

In order to achieve the above object, the present invention, the connection line is provided with a predetermined length, the LED lamp is configured by coupling the waterproof connection jack to one end of the connection line; An installation frame provided with a plurality of LED lamp assembly holes so that the LED lamps can be attached and detached; A printed circuit board configured to receive an AC voltage from an external power supply and supply a constant voltage required for the LED lamp; And a plurality of arrangements are provided on one surface of the printed circuit board, characterized in that it comprises a distribution port configured to be coupled with the waterproof connection jack of the LED lamp to the electrically connected to the LED lamp.

Removable LED lighting module device of the present invention by improving the series of LED structure to be installed on the frame to the point light source structure that can be removable separately assembled, easy installation and maintenance, as well as partial LED of the plurality of LEDs installed in the frame Even if the damage occurs, only the damaged LED can be easily replaced and repaired, thereby significantly improving the handling and economical efficiency.
