1. an illuminated keyboard, is characterized in that comprising:

  • Keycap, this keycap has light-transmission character region, and this light-transmission character region has character area major axis;

    Circuit board, this circuit board has switch and transparent area, and this transparent area is positioned at the below in this light-transmission character region, and when this keycap declines and triggers this switch, this circuit board produces triggering signal;

    Base plate, this base plate has at least one extension, this extension is in order to provide support this circuit board, this base plate is in forming the first hollow hole in the position below switch, in this first hollow hole periphery and the below of this transparent area forms at least one second hollow hole, this extension separates this first hollow hole and this second hollow hole, the central point of this first hollow hole and the central point of this second hollow hole are positioned at the first virtual line section, and the angle of the axis of this projection of character area major axis on this base plate and this first virtual line section is less than 60 degree;

    AndBacklight module, this backlight module is positioned at the below of this base plate, this backlight module has a plurality of scattering point, this a plurality of scattering point is positioned at immediately below this second hollow hole, this a plurality of scattering point penetrates the luminous energy transmitted in this backlight module, this luminous energy through this second hollow hole and this transparent area, and provides backlight to this light-transmission character region.
