Abstract
A light-emitting keyboard includes a keycap, a frame and a solid-state lighting source. The keycap has a light-entrance portion formed on the periphery thereof, and a touch surface for pressing by user. The keycap is made of light-guiding material and defines a light-guiding path from the light entrance portion to the touch surface. The frame is arranged adjacent to the keycap and surrounds the periphery of the keycap. The frame is made of light-guiding material and forms at least one light-outputting surface. The at least one light-outputting surface is contiguous to the light-entrance portion. The solid-state lighting source is fixed to the frame and emits light from the light-outputting surface into the light-entrance portion by the light-guiding path, and exits from the touch surface of the keycap. The instant disclosure also provides an illuminating structure of the keyboard, and a keycap thereof.
