An example of a light emitting unit for assigning addresses to lighting apparatuses and controlling each of the assigned lighting apparatuses according to the present invention will be described with reference to FIG. 7. Port 740, output port 750 and connection control means 835.

The controller 710 provides an infrastructure for overall control of the light emitter and connection and communication between the components.

The input port 740 is connected to the bridge device 410 connected in series or to an output port of another light emitting part of the front end to receive various control data and address data. The input port 740 has at least three lines so that one line is connected to ground and the other two lines are available for data reception.

The output port 750 transmits data transmitted through the input port 740 to the input port of the light emitting unit of the rear end connected in series. The output port 750 also has at least three lines, one of which is connected to ground and the other two lines are available for data transmission.

Here, according to the present invention, two lines for data transmission of the output port 750 are internally connected to two lines for data reception of the input port 740. In this case, the connection control means 735 according to the present invention may be provided between two lines connected internally between the input port 740 and the output port 750.

This may not be. That is, the light emitting part is disconnected from the light emitting part of the rear end.

After that, if the data input through the input port 740 is data including the real address data after the address allocation starts, the controller 710 again receives and stores the address data, and / or the stored address. By comparing with the data, it is determined whether the actual address data inputted is processed and stored or transmitted to the light emitting unit at the next stage.

When the controller 710 determines the storage of the inputted real address data as described above, the controller 710 controls to process and store the corresponding address data, and since the controller is assigned an address, the controller 710 connects the address data to the next light emitting unit. The connection status with the rear end that was released is made into a connection again.

To this end, the controller 710 changes the connection state of the connection control means 835 to open so that the input port and the output port are electrically opened so that data received through the input port is output through the output port. Control to be transmitted.

Similarly, when the real address data is received again, the next step is performed without additional operation according to the reception of the address data unless the address data previously stored by the new address data initialization request is cleared. Passes data to the light emitting unit.

If the control data for the control of the actual light emitting unit 730 is received after the above-described address assignment, the controller 710 checks the address data to perform the control included in the received control data. To control.

As described above, according to the present invention, an address can be automatically assigned to lighting devices of the lighting system, and the lighting device (s) assigned to the address can be controlled in groups or individually. A simple circuit configuration based on how the devices are connected allows a lighting system to automatically assign a unique address to each lighting device.

Preferred embodiments of the present invention described above are disclosed for purposes of illustration, and those skilled in the art having various ordinary knowledge of the present invention may make various modifications, changes, and additions within the spirit and scope of the present invention. And additions should be considered to be within the scope of the following claims.
