Illuminated keycap for generating soft light

摘要

An illuminated keycap for generating soft light is located in a keyboard which includes a command circuit board located beneath the keycap and a lighting unit to project light to the keycap. The keycap includes a press surface, a connecting section extended from the press surface towards the command circuit board and a color display surface extended from the connecting section and parallel to the press surface. The press surface, connecting section and color display surface form a light retaining zone. The press surface has a top surface coated with a first pigment layer. The color display surface has a bottom surface coated with a second pigment layer whose color is different from the first pigment layer. The first and second pigment layers form a mixed color so that light generated by the lighting unit to enter the light retaining zone is emitted softly through the connecting section.

1. An illuminated keycap for generating soft light located in a keyboard which includes a command circuit board located beneath the keycap and triggered by a vertical movement of the keycap to issue a keyboard command signal, and at least one lighting unit located inside to provide light projecting to the keycap, comprising:
a press surface, a transparent connecting section extended from the press surface towards the command circuit board and a color display surface extended from the connecting section and parallel to the press surface; the press surface, the connecting section and the color display surface jointly forming a light retaining zone in the keycap, the press surface including a top surface coated with a first pigment layer, the color display surface including a bottom surface coated with a second pigment layer whose color is different from that of the first pigment layer, the first pigment layer and the second pigment layer forming a mixed color such that the light generated by the lighting unit to enter the light retaining zone is emitted softly through the connecting section.
