The connection detecting unit 41 detects the connection state when the power adapter 200 of the light emitting panel 10 is connected to the plurality of connection terminals 31 numbered in the hub switching module 30. Then it is output to the lighting control unit 50.

At this time, the lighting control unit 50 is to display the number of the light emitting panel 10 connected to the hub switching module 30 through the screen unit 42 as described above.

Accordingly, the user searches for the number of the light emitting panel 10 that is connected through the search key 43 as well as the up / down keys 44 and 45, and then needs to be turned on in the searched light emitting panel 10. The light emitting panel 10 is selected and designated through the setting key 46.

That is, when the user wants to light up all the light emitting panels 10 coupled to the ceiling or the wall, all the light emitting panels 10 connected to the connection terminal 31 are selected and specified through the setting key 46.

Then, the information selected by the setting key 46 is stored in the memory unit 51 through the lighting control unit 50 is completed.

In addition, the search key 43 as well as the up / down keys of the light emitting panel 10 that the user wants to sequentially light up the plurality of light emitting panels 10 connected to the connection terminal 31 of the hub switching module 30. (44) (45) and setting key (46) select and specify the order of lighting.

That is, the user bundles the light emitting panel 10 into one or two or more group units and selects and specifies the bundle information through the setting key 46, and the light emitting panel 10 selected and designated by the setting key 46 is selected. Is stored in the memory unit 51 through the lighting control unit 50.

In addition, the search key 43 as well as the up / down keys may be used for only the light emitting panel 10 in which the user wants to light locally the plurality of light emitting panels 10 connected to the connection terminal 31 of the hub switching module 30. Selection is made via (44) (45) and setting key (46).

Then, the information of the light emitting panel 10 selected and set by the setting key 46 is completed in the memory unit 51 through the lighting control unit 50.

In this case, in the local lighting mode, only the first local lighting mode a for lighting only one light emitting panel 10 and only the light emitting panel 10 disposed in N columns of horizontal lines among the plurality of light emitting panels 10 coupled to each other. A second local lighting mode (b), a third local lighting mode (c) for lighting only the light emitting panel 10 disposed in the column M of the vertical line among the plurality of light emitting panels 10, and a plurality of light emitting panels The fourth local lighting mode d, which lights only the light emitting panels 10 arranged at diagonal lines, of course, may be used, as well as shapes (eg, triangular, square, cross, rhombus, etc.) of the plurality of light emitting panels 10 which are combined. ), The light emitting panel 10 can be selected and specified by subdividing it into a fifth local lighting mode (e) that lights only the light emitting panel 10 arranged to represent the "

Subsequently, in a state where the lighting mode of the plurality of light emitting panels 10 coupled as described above is stored in the memory unit 51, the user may turn off the light intensity control knob 49 provided in the control terminal 40 at an off position. When gradually rotating, the light intensity of the light emitting panel 10 selected by the lighting mode of the plurality of light emitting panel 10 coupled from the rotation of the light intensity control unit 49 becomes brighter gradually.

At this time, when the user rotates the first mode control port 47 of the control terminal 40 to the full light mode (M1), the signal according to the position of the first mode control port 47 is a lighting control unit ( Output as 50),

The lighting control unit 50 turns on all of the hub switches SW1, SW2,..., SWn in the hub switching module 30 connected to the plurality of light emitting panels 10 while searching the memory unit 51 storing the lighting mode. A control operation for switching is performed.

The method of claim 3, wherein the local lighting mode, A first local lighting mode for lighting only one light emitting panel, a second local lighting mode for lighting only a light emitting panel arranged in column N of a horizontal line among the plurality of light emitting panels, and arranged in a column M of a vertical line among the plurality of light emitting panels The third local lighting mode for lighting only the light emitting panel, the fourth local lighting mode for lighting only the light emitting panel arranged in a diagonal line among the plurality of light emitting panels, and the light emitting panel arranged to express a figure shape among the plurality of light emitting panels. Lighting device and light intensity variable type lighting device characterized in that it further comprises a fifth local lighting mode for lighting. Manipulating the light intensity control tool and the first mode control device after setting a lighting mode of a plurality of light emitting panels and whether the light emitting panel is turned on according to the lighting mode; Judging whether the operation signal of the first mode control tool is a full lighting mode, a sequential lighting mode, a local lighting mode; Turning on all of the hub switches in the hub switching module when the operation signal is the entire lighting mode to light up the entire combined light emitting panel; If the operation signal is a sequential lighting mode, sequentially lighting the designated light emitting panel while repeating on / off switching of the hub switch grouped in one or more group units; Determining whether the operation signal of the second mode control tool is input if the operation signal is the local lighting mode; If the operation signal of the second mode control device is input as a result of the determination, locally turning on the hub switch in the hub switching module according to the input operation signal to locally light only the designated light emitting panel; Determining whether a signal for adjusting the light intensity of the lighting panel is input when the lighting panel is turned on for each lighting mode; And, If the light intensity control signal is input as a result of the determination, controlling the amount of current supplied to the light emitting panel to be lit for each lighting mode according to the light intensity control signal; Lighting pattern and light intensity variable type lighting control method characterized in that proceeds to. The method of claim 5, wherein the lighting mode setting step, Selecting a local lighting mode, a sequential lighting mode, a local lighting mode; Selecting and specifying a light emitting panel corresponding to the sequential lighting mode when the sequential lighting mode is selected from the step; Selecting and specifying a light emitting panel corresponding to the local lighting mode when the local lighting mode is selected from the above steps; Lighting control method of the lighting pattern and light intensity variable type, characterized in that it further proceeds. The method of claim 5, wherein the local lighting step of the light emitting panel, Lighting only one light emitting panel; Lighting only the light emitting panels arranged in the N columns of the horizontal lines among the plurality of light emitting panels coupled; Lighting only the light emitting panels arranged in column M of the vertical lines among the plurality of combined light emitting panels; Lighting only the light emitting panels arranged in diagonal lines among the plurality of light emitting panels coupled; And lighting only the light emitting panels arranged to express a figure shape among the plurality of combined light emitting panels; Lighting pattern and light intensity variable type lighting control method characterized in that it further comprises.
