In FIG. 2, the switch means 151 and the lighting means of the lighting apparatus 100 are connected by one control line (for example, a power line), and control is possible through the corresponding control line. As a light source that can be used for the lighting means of the present invention, various illumination light sources including an LED element can be used.

The main controller 200 is connected to the lighting device 100 through a control line or by wireless communication. Communication connection between the lighting device 100 can be a wired, wireless connection using a commonly used connection technology. In particular, in the case of wireless, infrared communication (Infrared, IrDA) is also possible.

The central controller 200 transmits a control command frame to the lighting device 100, and the control command frame is transmitted to the destination lighting device through the switch means 151 of each lighting device 100. The light emitting means 112 is controlled using the information in the writing control data field of the transferred control command frame. Control state information of the lighting device 100, failure information of the lighting device 100, etc. are inserted into the corresponding control command frame and transmitted to the central controller 200.

3 and 4, the lighting device 100 having a network switch function according to the present invention includes a plurality of input / output ports 160, switch means 151, and lighting means.
