CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. application Ser. No. 14/324,654, filed Jul. 7, 2014, which claims priority under 35 U.S.C. Â§119 to Korean Patent Application No. 10-2013-0078497, filed Jul. 4, 2013, which are hereby incorporated by reference in their entirety.

BACKGROUND

The embodiment relates to a lighting system. More particularly, the embodiment relates to a lighting system which can control the operational state of a plurality of lighting devices in real time by using a lighting control device, such as a terminal, and a method of controlling the same.

In general, in order to control the operational state (on state, off state and dimming state) of a lighting device, a user needs to manually manipulate a switch connected to the lighting device through a cable.

However, the patient, the senior citizen or the infirm who cannot move freely, or children who cannot reach the switch may feel inconvenience when controlling the lighting device using the switch.

Meanwhile, an incandescent lamp or a fluorescent lamp is mainly used as the lighting device. However, the incandescent lamp or the fluorescent lamp causes great power consumption under the same lighting efficiency and has a short life cycle. In particular, mercury may be flown out when the fluorescent lamp is discarded, causing the serious problem of environmental pollution.

For this reason, recently, a lighting device, which uses an environmental-friendly LED having low power consumption and semi-permanent life span as a light source, has been spotlighted.

Especially, the LED has advantages of easily controlling the degree of illumination and adjusting color tones as well as the above advantages.

However, only is the on-off control possible for the lighting device according to the related art by using a remote controller or a cable switch.

For this reason, the lighting device according to the related art causes waste of energy. In addition, the degree of illumination based on use environment cannot be controlled and the operational states of a plurality of lighting devices cannot be recognized from the outside.

BRIEF SUMMARY

The embodiments provide a lighting system capable of checking and changing the operational state of a plurality of lighting devices in real time by using an application installed in a lighting control device, such as a terminal, and a method of controlling the same.

Technical objects of the embodiment may not be limited to the above object and other technical objects of the embodiment will be apparent to those skilled in the art from the following description.

A lighting system according to the embodiment may include a lighting device; and a graphic user interface displayed on a touch screen of a lighting control device to control the lighting device, wherein the graphic user interface may include a first region to display a map for an installation space of the lighting device and a lighting icon corresponding to the lighting device in the map; and a second region to display a menu for setting a control condition of the lighting device corresponding to the lighting icon, and wherein the map may include a plurality of division spaces obtained by dividing the installation space into a plurality of regions and the lighting icon may be displayed in a specific division space corresponding to an actual installation portion of the lighting device.

The lighting icon may include a first type lighting icon to represent the lighting device under on-state; and a second type lighting icon to represent the lighting device under off-state.

The lighting icon may further include a third type lighting icon to represent the lighting device under off-state of communication linkage to the lighting control device.

When a first type specific lighting icon is first-selected from among lighting icons displayed in the first region, the first-selected first type specific icon may be changed into a second type lighting icon, and when a second type specific lighting icon is first-selected from among the lighting icons displayed in the first region, the first-selected second type specific icon may be changed into the first lighting icon.

The graphic user interface may further include a third region to display a menu for changing an operation state of the lighting device corresponding to a second-selected lighting icon as a specific lighting icon is second-selected from among lighting icons displayed in the first region, and wherein the menu displayed in the third region may include a first menu to change a state of a power source of the lighting device corresponding to the second-selected lighting icon; and a second menu to change a brightness of the lighting device corresponding to the second-selected lighting icon.

The menu displayed in the third region may further include a third menu to select a group control, the graphic user interface may further display a group selection menu to select one specific group from among a plurality of groups as the third menu is selected, and the group control may be used to collectively control a plurality of lighting devices which are grouped as one same group.

The menu displayed in the second region may include at least one of a load menu to select a type of the map displayed in the first region, an auto-control menu to automatically control the lighting device according to a distance between the lighting device and the lighting control device, a group menu to collect a plurality of lighting icons corresponding to a plurality of lighting device as one group, a general menu to set a display type of an icon displayed in the graphic user interface and a help menu to display a help.

The menu displayed in the second region may include a registration menu to register unregistered lighting devices from among lighting devices located around the lighting control device.

The lighting control device may search for the unregistered lighting devices from among the lighting devices located around the lighting control device when the registration menu is selected, and a candidate icon may be displayed in the graphic user interface to register the unregistered lighting devices according to a search result of the lighting control device.

The candidate icon may be shifted to a specific division space of a plurality of division spaces displayed in the first region, which corresponds to an actual installation position of a corresponding lighting device, according to selection of a user, and the lighting device corresponding to a selected candidate icon may perform a register dimming operation as the candidate icon is selected.

Meanwhile, a method of controlling a lighting device according to the embodiment may include executing an application to control the lighting device; displaying a graphic user interface on a touch screen of a lighting control device as the application is executed; and controlling the lighting device by using the displayed graphic user interface, wherein the graphic user interface may include a first region to display a map for an installation space of the lighting device and a lighting icon corresponding to the lighting device in the map; and a second region to display a menu for setting a control condition of the lighting device corresponding to the lighting icon, and wherein the map may include a plurality of division spaces obtained by dividing the installation space into a plurality of regions and the lighting icon is displayed in a specific division space corresponding to an actual installation portion of the lighting device.
