ABSTRACT:
An electrophoretic light switch is provided for controlling light in a light pipe having a transparent inner conductor, an outer conductor and a solution containing charged particles. Light is absorbed by the solution when the particles are attracted to the inner conductor causing the light intensity in the light pipe to be reduced.
