Abstract
A system includes a space with at least one window separating an interior space from an exterior space; band-pass filter layers provided in the window and configured to block narrowband light; and a light source provided in the interior space and including at least red, green and blue light emitting diodes. The light source is configured to selectively provide broad spectrum white light and narrowband light blocked by the filter layers in the window, such that the interior space is visible from the exterior space through the window when illuminated by the broad spectrum light, but not visible when illuminated by the narrowband light.
