초록

A transparent smart light source capable of adjusting an illumination direction is provided. The transparent smart light source includes a reflectance/transmittance tunable device that adjusts an illumination direction by reflecting or transmitting light emitted from a transparent organic light-emitting diode (OLED) according to applied voltage, and thus can simply adjust the illumination direction according to purpose. Accordingly, it is possible to prevent optical loss in an unnecessary direction, and power consumption can be reduced. Furthermore, the transparent smart light source can serve as a curtain blocking out external light, as well as a lighting device, and also can be combined with a solar cell to generate electric power.
