US 10,312,035 B2 · Luminous keyboard

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.
