Description

FIELD OF THE INVENTION [0001] The present invention relates to a light device, a lighting device system,

The present invention relates to a lighting device and a method of registering the lighting device.

In general, a switch connected directly to the lighting device and to the wire is manually operated to turn the lighting device on or off.

In such a case, there has been an inconvenience in turning on or off the lighting device for a patient who is inconvenient in motion, a senior citizen or a child whose hand does not reach the switch.

Recently, the wireless lighting control market, which controls the ON / OFF or dimming function of the office, the store or the home lighting in a big building, is getting bigger. In order to control each light by radio, a communication module is mounted in each light. The user sends the lighting control signal through the gateway wirelessly, and the gateway must know the address (MAC address) of the communication module of the lighting at the position that the user wants to control.

Therefore, the existing lighting registration method has a problem that when the lighting installer installs the lighting, it is difficult to view the map of the installation place and register the lighting location after confirming the address of the communication module in each lighting. At this time, if the installer mistakes the address of each light by mistake, there may be a situation where the other light may operate when the user controls each light. In order to correct this, there is a fatal drawback in that the installer has to remove all the lights from the ceiling to re-check the address of the communication module and register it. Problems also arise when changing the position of the light, or when installing or removing the light.

Embodiments provide a method of registering a lighting device and a lighting device.

According to an embodiment of the present invention, there is provided a lighting apparatus including a control unit for generating an on-off signal according to information on a unique address, and a light source emitting light according to the on-off signal and emitting visible light containing information on the unique address.

The embodiment further includes at least one illuminating device for emitting information on a unique address in visible light and a gateway system for controlling the illuminating device by registering information on the unique address of the illuminating device, The system provides a lighting system in which a user receives visible light of the lighting device at a specific location with an optical receiver, reads information on the unique address placed in the visible light, and receives the information.

According to the embodiment, each illuminating device transmits its own address using visible light communication (VLC), and under the lighting device where the user wishes to register a device such as a tablet having map information of the place where the illuminating device is located, Can be automatically registered. Therefore, the registration time can be drastically reduced, and the mistake of the installer can be prevented. In addition, when additional installation, removal, or maintenance of a lighting device is performed, the lighting device alone can easily recognize and register the address.
