PURPOSE: According to the transparency smart light source capable of the adjustment of the lighting direction is purpose, the loss of the quantity of light to the unnecessary direction is prevented by simply controlling the lighting direction. CONSTITUTION: A transparency smart light source comprises the transparent OLED(100a) and the reflectivity/transmittance variable element(300) which can become insane to bidirectional. The transparent OLED is proceed the radiation from the front side and rear side. The reflectivity/transmittance variable element is integrated in the transparent OLED. According to the reflectivity/transmittance variable element is the polarity of the applied voltage and size, the reflectivity/transmittance is varied. |
