Abstract
A keyboard illumination structure. The structure includes a base board, a circuit board, an elastic member, a bridge mechanism, a key cap and a centralized lighting element located in the keyboard. The lighting element may generate light to pass through the keyboard for indicating the positions of the button keys, vital keys or function keys so that users may locate the required keys rapidly.
Claims15
An improved keyboard illumination structure comprising:
- a base board, a circuit board, an elastic member, a bridge mechanism, and a key cap housed in a keyboard, and a centralized lighting element located in the keyboard;
- wherein when the key cap subjects to an external pressing force, the bridge mechanism will be pressed downwards to compress and deform the elastic member which in turn presses the circuit board to transmit a signal, the lighting element generating light to pass through the keyboard for indicating positions of button keys, vital keys or function keys located on the keyboard adapted for users to locate required ones of the keys rapidly;
- and
- wherein the lighting element is selectively a cold light board or a cold cathode board made in a plate form.
