Abstract

In an illumination device, a surface light emission module includes a panel power input unit connected to a base power input unit and a panel power output unit connected to a base power output unit for supplying power to a surface light emission panel. A connection panel, by being installed in an unselected scheduled light emission region, directly connects the base power input unit to the base power output unit.

Claims (45)

1. An illumination device comprising:

one or more surface light emission modules including a surface light emission panel emitting light by being supplied with power;

a panel base partitioned into two or more scheduled light emission regions and configured to make the surface light emission panel to emit light by installing the surface light emission module in the selected scheduled light emission region;

a power passing means configured to pass the power from the adjacent scheduled light emission region; and

a power supply configured to supply the power to the surface light emission panel, wherein

each of the scheduled light emission regions has a base power input unit and a base power output unit, and by the base power output unit being connected to the base power input unit between adjacent scheduled light emission regions, a series connection line is constituted of the power supply and the two or more scheduled light emission regions,

the surface light emission module includes a panel power input unit connected to the base power input unit and a panel power output unit connected to the base power output unit for supplying the power to the surface light emission panel, and
