wherein when an image including at least some of the lighting devices installed in the specific indoor region is received from the camera, the controller receives the identification information from the at least some of the lighting devices installed in the specific indoor region, based on an input of a user for the image, and

wherein the controller allows at least one specific region corresponding to the lighting devices to be displayed distinguishably from the image received from the camera and selects lighting devices, from which the identification information is to be requested, in the at least one specific region, based on a sensed input of a user.

2. The mobile terminal of claim 1 , further comprising a display unit displaying a graphic object corresponding to each of the plurality of lighting devices.

3. The mobile terminal of claim 2 , wherein the identification information further comprises information related to a position of each of the plurality of lighting devices, and

wherein the mobile terminal calculates the position of each of the plurality of lighting devices, based on the position-related information included in the identification information and determines positions of graphic objects displayed on the display unit, based on the calculated position.

4. The mobile terminal of claim 3 , wherein the information related to the position of each of the plurality of lighting devices is information about a relative position of each of the plurality of lighting devices calculated by a predetermined separate position tracker.

5. The mobile terminal of claim 4 , wherein the information related to the position of each of the plurality of lighting devices is information about where the relative position of each of the plurality of lighting devices calculated by the position tracker is matched with drawing information corresponding to the specific indoor region.

6. The mobile terminal of claim 2 , wherein the controller generates a group including at least one graphic objects, based on an input of a user applied to the display unit, and

wherein when a control command for the generated group is selected, the controller controls the wireless communicator so that a control signal corresponding to the selected control command is simultaneously transmitted to lighting devices corresponding to the graphic objects of the group.

7. The mobile terminal of claim 6 , wherein the input of the user is a trajectory of a touch and drag input of the user applied to the display unit, and

wherein the group is generated based on a closed curve generated based on the touch and drag input.

8. The mobile terminal of claim 1 , wherein the lighting devices installed in the specific indoor region comprise at least one infrared sensor for sensing an infrared signal and at least one photo sensor for sensing a light signal having a predetermined pattern, and

wherein the plurality of lighting devices are some lighting devices which are selected from among the lighting devices installed in the specific indoor region, based on the infrared signal or the light signal transmitted from the mobile terminal or a predetermined separate device.

9. The mobile terminal of claim 1 , wherein the lighting devices installed in the specific indoor region transmit a predetermined signal in a specific direction, and

wherein the mobile terminal senses a signal transmitted from at least one of the lighting devices installed in the specific indoor region and receives the identification information from lighting devices corresponding to the sensed signal.

10. The mobile terminal of claim 1 , wherein each of the lighting devices installed in the specific indoor region has a code which corresponds to predetermined information and is exposed to at least a portion of an external appearance thereof, and

wherein the mobile terminal recognizes the exposed at least one code through a predetermined separate device and receives the identification information from at least one lighting device corresponding to a result of the recognition.

11. The mobile terminal of claim 1 , wherein the mobile terminal is a dongle type device connected to another device.

12. The mobile terminal of claim 11 , wherein the mobile terminal transmits graphic objects respectively corresponding to the plurality of lighting devices and position information based on a relative position of each of the plurality of lighting devices to the other device, and

wherein the other device displays the graphic objects respectively corresponding to the plurality of lighting devices on a display unit, based on the graphic objects and the position information transmitted from the mobile terminal.

13. A control method of a mobile terminal, the control method comprising:

searching for a controllable lighting device, based on identification information received from a plurality of lighting devices;

displaying graphic objects corresponding to the found at least one lighting devices;

generating a group including at least one graphic objects, based on an input of a user for the displayed graphic objects; and

when there is a control command of the user for the generated group, transmitting a control signal corresponding to the control command to lighting devices respectively corresponding to the graphic objects included in the group,

wherein based on information obtained through the mobile terminal or a separate device, the identification information is received in response to a request of the mobile terminal transmitted to at least some of lighting devices installed in a specific indoor region, or when the mobile terminal satisfies a predetermined condition, the identification information is transmitted from at least some lighting devices pre-selected by a predetermined manner from among the lighting devices installed in the specific indoor region,

wherein the searching for a controllable lighting device further comprises:

receiving an image including at least some of the lighting devices installed in the specific indoor region;

displaying distinguishably at least one specific region corresponding to the lighting devices;

selecting at least some of the lighting devices, from which the identification information is to be requested, in the at least one specific region, based on a sensed input of a user; and

receiving the identification information from the at least some of the lighting devices.
