Estimating the term…
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.
A light guidance illuminating keyboard, which utilizes a plurality of press-key devices, and a base plate being provided with a plurality of through-holes, so as to generate a control signal to an electronic device when a user presses down the press-key devices, comprising a light guide plate, which is provided at an end of the base plate opposite to the press-key devices and is defined into at least one through-hole that forms an independent optical path;
The light guidance illuminating keyboard according to claim 5, wherein two sides of the light guide plate are provided respectively with a light emitting element which is at an angle of a best light reflection rate, with respect to the light guide plate.
The light guidance illuminating keyboard according to claim 5, wherein a surface of the light guide plate is formed with a rough surface.
The light guidance illuminating keyboard according to claim 5, wherein the light guide part is in a V-shape pattern, a U-shape pattern or a semi-arc pattern.
The light guidance illuminating keyboard according to claim 5, wherein the light emitting element is an LED.
