Referring to the operation of the lighting device according to the present invention having such a configuration as follows. First, before describing the operation of the lighting apparatus according to the present invention, the controller 50 receives a nature-related image supplied from nature-related contents among various contents supplied from the communication interface 51 or the memory card interface 53. The received nature-related image is converted into nature-related image data so as to be expressed through the lighting device 70 and provided to the natural content database 71. The natural content related database 71 stores the received natural related image data.

In addition, the controller 50 receives a user related image including a still image or a video supplied from a content desired by a user among various contents supplied from the communication interface 51 or the memory card interface 53, and receives the received user related image. The image is converted into user-related image data so that the image can be represented through the lighting device 70 and provided to the user content database 73. The user content related database 73 stores the received user related image data.

Thereafter, the control unit 50 sets the basic lighting mode when the lighting on signal of the lighting on / off switch 11 of the operation unit 10 is received through step 101.

When the on / off switch 11 of the operation unit 10 is selected by the user, the control unit 50 sets the basic light control mode, and at this time, the brightness switch 13 and the operation unit 10 of the operation unit 10 by the user. Brightness and color are controlled via a warm end cool light switch 15.

That is, the brightness of the lighting (White Dimming + /-) and the warm and cool lighting is set through the brightness switch 13 and the warm end cool light switch 15.
