Abstract
A keyboard with lighting source provides two conductive sheets made of copper foil, tin foil or aluminum foil as electrodes of semiconductor light emitting components. Multiple through holes are provided at the upper conductive sheet electrode. The semiconductor light emitting components are attached to and connected to the lower conductive sheet electrode at the areas exposing from the through holes and the upper conductive sheet electrode at the areas near the through holes. No light guide plate or printed circuit board with complicated layout is necessary to meet the required features such as thinness, uniform luminance, and simplicities of structure and fabricating process.
Claims8
A keyboard with lighting source comprising:
- a button key circuit set;
- a lower conductive sheet electrode;
- an upper conductive sheet electrode disposed between the button key circuit set and the lower conductive sheet electrode, having an insulation layer to isolate the lower conductive sheet electrode and a plurality of through holes passing through the insulation layer;
- and
- a plurality of semiconductor light emitting components being attached to and electrically connected to the lower conductive sheet electrode at areas exposed with the through holes, and being attached to and electrically connected to the upper conductive sheet electrode at areas next to the through holes.
