Light Guidance Illuminating Keyboard

摘要

A light guidance illuminating keyboard utilizes plural press-key devices and a base plate having plural through-holes to generate a control signal to an electronic device when a user presses down the press-key devices. A back surface of the base plate is a light guide plate on which is defined into at least one through-hole which forms an independent optical path. A side of the light guide plate is a light emitting element. When the light emitting element produces light, the light is reflected onto the through-holes on the base plate through the light guide plate and penetrates out of the through-holes, such that the press-key devices can manifest various visual effects according to the light produced by the light emitting element.
