Claim Text:
1. A luminous keyboard, comprising: a sensing module for generating at least one non-contact key signal; at least one key disposed over said sensing module, wherein when said at least one key is depressed, said at least one non-contact key signal is correspondingly generated by said sensing module; a key substrate for supporting said at least one key and having at least one opening aligned with said at least one key; at least one bottom-emitting type illumination element disposed under and aligned with said at least one opening and said at least one key for actively emitting an upward light beam toward said at least one key; at least one light-transmissible elastic element arranged between said at least one key and said at least one bottom-emitting type illumination element for providing an elastic force to said pressed at least one key, wherein said at least one light-transmissible elastic element is configured to cover said at least one bottom-emitting type illumination element while allowing said upward light beam to transmit therethrough, and said at least one light-transmissible elastic element is contacted by said at least one key through said at least one opening; and plural microstructures formed on said at least one light-transmissible elastic element for changing an optical path of said upward light beam passing therethrough; wherein each of said plural microstructures is a V-cut structure or a texturing structure.
