ABSTRACT:
A system and a method for using ePaper as a light control media in lighting fixtures or other light enhanced applications to modify, dim or color-shift the light used for lighting the space. One system includes a light source, an ePaper reflector with controllable reflectivity for controlling the light reflected from the reflector and/or an ePaper baffle with controllable translucency for controlling the light through the baffle. The light incident on the ePaper media may include light from other sources such as natural light. One method compares desired lighting in a space to characteristics of the light source. Characteristics of the ePaper media are then adjusted to provide the desired amount of light to the objects under illumination. Reflectivity from walls and furniture may be controlled by applying ePaper to their surfaces. The light source and the ePaper media may be controlled simultaneously to control the lighting.
