Lighting keyboard, backlight module and lighting board

A lighting keyboard comprising:

• at least one first keyswitch;
• at least one second keyswitch arranged parallel to the at least one first keyswitch;
• and
• a backlight module comprising:
• a lighting board comprising a plurality of illuminants corresponding to the at least one first keyswitch and the at least one second keyswitch;
• and
• a shielding sheet comprising:
• a plurality of first outlet windows;
• a plurality of first block patterns disposed within the plurality of first outlet windows respectively, each of the first block patterns respectively corresponding to one of the illuminants, the first block patterns forming a first row pattern;
• at least one second outlet window;
• and
• a plurality of second block patterns disposed within the at least one second outlet window, each of the second block patterns respectively corresponding to one of the illuminants, the second block patterns forming a second row pattern;
• wherein the lighting board further comprises a pair of non-intersecting traces passing through the plurality of first outlet windows, and the first row pattern is at least partially located between the pair of non-intersecting traces.

A lighting board comprising:

• a plurality of illuminants aligned into two rows;
• a first pair of non-intersecting traces;
• a second pair of non-intersecting traces;
• and
• a shielding sheet comprising:
• a plurality of first outlet windows;
• a plurality of first block patterns disposed within the plurality of first outlet windows respectively, each of the first block patterns respectively corresponding to one of the illuminants, the first block patterns forming a first row pattern;
• at least one second outlet window;
• and
• a plurality of second block patterns disposed within the at least one second outlet window, each of the second block patterns respectively corresponding to one of the illuminants, the second block patterns forming a second row pattern;
• wherein the first row pattern is located between the first pair of non-intersecting traces passing through the plurality of first outlet windows, the second row pattern is located between the second pair of non-intersecting traces, and the first row pattern is different from the second row pattern.
