An illuminated keyboard includes a key structure, a key wiring board, and a light-emitting element. The light-emitting element is located at a lateral side of the key wiring board. The key structure is disposed over the key wiring board. When the key structure is depressed, the key wiring board is triggered to generate a corresponding key signal. Moreover, a light-guiding structure is formed on the key wiring board. The light beam transferred within the key wiring board is guided by the light-guiding structure to be scattered to the key structure. After the light beam to be scattered to the key structure is converged by a light-converging microstructure on the key wiring board, the light beam is converged and centralized to be directed to keycap of the key structure. |

1. An illuminated keyboard, comprising:
at least one light-emitting element for emitting at least one light beam; a key wiring board for generating at least one key signal and transferring said at least one light beam, wherein said key wiring board comprises an upper wiring plate, a lower wiring plate and a spacer layer, wherein said upper wiring plate is made of a light-transmissible material, said lower wiring plate is made of a light-guiding material for transferring said at least one light beam, and said spacer layer is arranged between said upper wiring plate and said lower wiring plate; at least one key structure disposed over said key wiring board, wherein when said at least one key structure is depressed, said key wiring board is triggered to generate said at least one key signal; at least one light-guiding structure formed on said lower wiring plate and aligned with said at least one key structure, wherein said at least one light beam from said at least one light-emitting element is guided by said at least one light-guiding structure so as to be scattered to said at least one key structure; and at least one light-converging microstructure formed on said upper wiring plate and aligned with said at least one light-guiding structure, wherein after said at least one light beam to be scattered to said at least one key structure is converged by said at least one light-converging microstructure, said converged light beam is directed to at least one keycap of said at least one key structure.
