Abstract
An illuminated keyswitch structure and an illuminating module thereof are provided. The illuminating module includes a drive circuit board having a reflector layer disposed thereon, a light-emitting part disposed on the drive circuit board and proximate to the reflector layer, a covering structure having an island-shaped covering portion, and a spacer adhered between the covering structure and the drive circuit board and having a through hole and an adhesive-less clearance fringe at least partially surrounding the through hole, wherein the island-shaped covering portion covers above the light-emitting part and the through hole.
Claims20
An illuminating module adapted to illuminate a keyswitch, comprising:
- a drive circuit board, having a reflector layer disposed thereon;
- a light-emitting part, disposed on the drive circuit board and proximate to the reflector layer;
- a covering structure, having an island-shaped covering portion;
- and
- a spacer, adhered between the covering structure and the drive circuit board, the spacer having a through hole and an adhesive-less clearance fringe at least partially surrounding the through hole,
- wherein the island-shaped covering portion covers above the light-emitting part and the through hole.
An illuminated keyswitch structure, comprising:
- a base plate, having an opening;
- a keycap disposed opposite to the base plate;
- and
- an illuminating module, comprising:
- a drive circuit board, having a reflector layer disposed thereon;
- a light-emitting part, disposed on the drive circuit board and proximate to the reflector layer;
- a covering structure, having a frame-shaped covering portion and an island-shaped covering portion;
- and
- a spacer, adhered between the covering structure and the drive circuit board, the spacer having a through hole corresponding to the opening and an adhesive-less clearance fringe at least partially surrounding the through hole,
- wherein the frame-shaped covering portion surrounds an outline of the keycap, and the island-shaped covering portion covers above the light-emitting part and the through hole.

- a light-emitting part, disposed on the drive circuit board and proximate to the reflector layer;
- a covering structure, having an island-shaped covering portion;
- a spacer, adhered between the covering structure and the drive circuit board, the spacer having a through hole and an adhesive-less clearance fringe at least partially surrounding the through hole;
- and
- a light-output pattern, comprising a reflective pattern on the reflector layer and a diffusion pattern on the spacer,
- wherein the island-shaped covering portion covers above the light-emitting part and the through hole, and the light-output pattern is substantially disposed adjacent to the island-shaped covering portion and configured to direct light upward.
