Abstract: An illuminated keyboard with an optical switch is provided. The illuminated keyboard includes a circuit board and plural keys. The circuit board includes plural light-emitting elements. Each light-emitting element is aligned with the corresponding key. The key includes a keycap, a housing, a triggering post, a light guide element and a light guide frame. The keycap is located over the housing. The triggering post, the light guide element and the light guide frame are disposed within the housing. Moreover, the light guide frame is arranged around the triggering post. After a light beam emitted by the light-emitting element is introduced into the housing, the light beam is guided to the light guide frame by the light guide element, and the light beam is scattered to a region around the triggering post and outputted from the keycap.

Abstract: A luminous keyboard includes a keypad module, plural light-emitting elements, an illumination circuit board and a light guide plate. The illumination circuit board has a light amount control structure. The light amount control structure is disposed on a circuit board main body or a protective layer of the illumination circuit board, and arranged between the light guide plate and the illumination circuit board. When the plural light-emitting elements emit light beams to the illumination circuit board, the light beams are projected on the light amount control structure, and 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.

Abstract: A luminous keyboard device includes a keypad module, a supporting plate, a flexible circuit board, a light-emitting element, a reflective layer, and a light guide plate. The supporting plate includes plural receiving parts. The flexible circuit board is contacted with the plural receiving parts to form plural bent structures. The light-emitting element and the reflective layer are disposed on the flexible circuit board. When a light beam is emitted by the light-emitting element, the portion of the light beam that is not directed to the light guide plate is reflected back to the light guide plate by the reflective layer on the plural bent structures. Consequently, the amount of light introduced into the light guide plate increases.

Abstract: A luminous keyboard device includes plural keys, a supporting plate, a light-emitting element, a membrane switch circuit module, and a light guide plate. The light guide plate is thicker than the light guide plate. The supporting plate has an opening corresponding to the light-emitting element. The light-emitting element is inserted into the opening. The light-emitting element is used for emitting plural light beams. A portion of the plural light beams are traveled along the path under the supporting plate and introduced into the light guide plate. Consequently, the portion of the plural light beams will be directed to the plural keys to illuminate the plural keys. Another portion of the plural light beams are traveled along the path over the supporting plate and introduced into the membrane switch circuit module. Consequently, the luminous efficiency of the slim-type luminous keyboard device is enhanced.

Abstract: A luminous keyboard includes a lateral-emitting type illumination element, a light guide panel, a sensing circuit pattern, a light-transmissible supporting plate, and plural keys. The lateral-emitting type illumination element is used for providing a light beam to the light guide panel. Consequently, the light beam can be diffused to the whole light guide panel. The light guide panel has plural light-guiding dots for collecting and scattering the light beam. The light-transmissible supporting plate is arranged between the light guide panel and the plural keys, and has plural light diffusion structures corresponding to the plural keys. The light beam scattered upwardly by each light-guiding dot is sequentially transmitted through the corresponding light diffusion structure and directed to the corresponding key. When one of the keys is moved toward the sensing circuit pattern, the sensing circuit pattern generates a corresponding non-contact key signal.

Abstract: An illuminated keyboard includes a key, a light guide plate, a sensing circuit layer, and a light-transmissible elastic element. The light-transmissible elastic element is disposed under the key. The light-transmissible elastic element has a light-diffusing part. The light guide plate and the sensing circuit layer are disposed under the light-transmissible elastic element. The sensing circuit layer is used for generating a non-contact key signal. After the light beam transferred within the light guide plate is transmitted upwardly through the light guide plate, the light beam is transmitted through the light-transmissible elastic element. Moreover, since the optical path of the light beam is changed by the light-diffusing part, the light beam can be projected onto the whole keycap more uniformly.

Abstract: A luminous keyboard includes a lateral-emitting type illumination element, a light guide plate, a reflective plate, a sensing circuit pattern, and plural keys. The lateral-emitting type illumination element is used for providing a light beam to the light guide plate, so that the light beam is diffused to the whole light guide plate. The light guide plate has plural light-guiding dots for collecting and scattering the light beam. The portion of the light beam scattered upwardly by the light-guiding dots is projected to the plural keys. The portion of the light beam scattered downwardly is reflected by the reflective plate and incident into the light guide plate again. The sensing circuit pattern is formed on a surface of the reflective plate. When any key is moved toward the sensing circuit pattern, the sensing circuit pattern generates a corresponding non-contact key signal.
