Patent number: 9892874Abstract: A luminous keyboard includes a keypad module, plural light-emitting elements, a light guide plate and a reflecting plate. The reflecting plate has plural light amount control structures. The light amount control structures are disposed on the reflecting plate, and located near the corresponding light-emitting elements. When the plural light-emitting elements emit light beams, the portions of the light beams that are not subjected to total internal reflection within the light guide plate are reflected by the reflecting plate. When the light beams are transferred through the light amount control structure, the reflected fraction of the light beams is reduced. Since the light beams are not very centralized, the problem of generating bright spots will be diminished.Type: GrantFiled: August 20, 2015Date of Patent: February 13, 2018Assignee: PRIMAX ELECTRONICS LTD.Inventor: Chung-Yuan Chen
