Abstract: A key structure, including a keycap, a movable mechanism, a support plate, a circuit board, and an indicator light-emitting element. The support plate and the movable mechanism pivotally connected to the support plate are disposed above the circuit board. The circuit board has a groove, and the indicator light-emitting element is embedded in the groove and is aligned with the keycap. The indicator light-emitting element emits light upward. The light may be directly emitted into the movable mechanism and is subsequently emitted outward through a light hole of the keycap.

Abstract: The present invention relates to a luminous keyboard, including a key, a support plate, a switch circuit board, a light guide plate, and a direct-type light emitting element capable of generating a beam. The support plate is located below the key, and the switch circuit board is disposed on the support plate. The light guide plate is located below the support plate and includes a concave structure, and the concave structure forms a reflective surface inside the light guide plate. The direct-type light emitting element is located below the concave structure. When the beam enters the light guide plate, the beam is reflected by the reflective surface to be fully reflected in the light guide plate, and the light guide plate guides the beam to be projected to a peripheral area of a key.
