Illuminated keyswitch structure and illuminating module

An illuminating module, configured to provide light toward an opening of a base plate of a keyswitch, comprising:

• a drive circuit board, disposed under the base plate;
• a spacer, disposed underneath the base plate and above the drive circuit board, the spacer having a through hole;
• a light-emitting part, disposed on the drive circuit board and in the through hole, the light-emitting part vertically corresponding to the opening of the base plate;
• and
• a light-permeable covering structure, including at least one first covering layer and at least one second covering layer,
• wherein the first covering layer covers above the light-emitting part and overlaps with a vertical projection of the opening of the base plate;
• wherein the second covering layer vertically corresponds to the light-emitting part and the opening of the base plate, the second covering layer blocks at least partial light of the light-emitting part toward the opening to reduce illuminating intensity provided there through,
• wherein the second covering layer is reflective to reflect light back into the through hole of the spacer and toward a reflector on the drive circuit board.

An illuminated keyswitch structure, comprising:

• a base plate, having a plurality of openings and a plurality of rib portions separating the openings;
• a drive circuit board, disposed under the base plate;
• a spacer, disposed underneath the base plate and above the drive circuit board, the spacer having a through hole;
• a light-emitting part, disposed on the drive circuit board and in the through hole, the light-emitting part vertically corresponding to one of the openings of the base plate;
• and
• a light-permeable covering structure, including at least one first covering layer and at least one second covering layer,
• wherein the first covering layer covers above the light-emitting part and overlaps with a vertical projection of said one of the openings of the base plate;
• wherein the second covering layer vertically corresponds to the light-emitting part and said corresponding one opening of the base plate, the second covering layer blocks at least partial light of the light-emitting part toward said corresponding one opening to reduce illuminating intensity provided there through,
• wherein the drive circuit board includes at least one face reflector and a plurality of dot reflectors, the face reflector is disposed on top of the drive circuit board, and the dot reflectors are located on the face reflector to vertically correspond to at least two of the openings of the base plate.

An illuminated keyswitch structure, comprising:

• a base plate, having a plurality of openings and a plurality of rib portions separating the openings;
• a drive circuit board, disposed under the base plate;
• a spacer, disposed underneath the base plate and above the drive circuit board, the spacer having a through hole;
• a light-emitting part, disposed on the drive circuit board and in the through hole, the light-emitting part vertically corresponding to one of the openings of the base plate;
• and
• a light-permeable covering structure, including a flat first covering layer, a cake-shaped first covering layer and at least one second covering layer,
• wherein the cake-shaped first covering layer covers above the light-emitting part and the drive circuit board within the through hole of the spacer, the cake-shaped first covering layer further overlaps with a vertical projection of said one of the openings of the base plate;
• wherein the flat first covering layer is configured between the base plate and the spacer without entering into the through hole,
• wherein the second covering layer is disposed at least partially above the flat first covering layer and vertically corresponds to the light-emitting part and said corresponding one opening of the base plate, the second covering layer blocks at least partial light of the light-emitting part toward said corresponding one opening to reduce illuminating intensity provided there through.
