Abstract (en)
[Object] In an illumination device, a user can arbitrarily switch an emission brightness of light. [Means for Settlement] An illumination device 1 includes: a plurality of EL panels 2 each including: a transparent EL element 20 configured by stacking on a transparent substrate 25 in turn an anode 26a formed of a transparent conducting film, a light emission layer 26b; and a cathode 26c formed of the transparent conducting film; and a fixture body 3 for retaining the EL panels 2 so that light emission regions of the plurality of EL panels 2 can overlap each other, and irradiates light of superposed emission lights of the plurality of EL panels 2. According to the configuration, when a user changes the number of the EL panels 2 to be overlapped on the basis of usage of the illumination device 1, the emission brightness of light can be arbitrarily switched.
