ABSTRACT:
A press button light emitting structure consists of a light-pervious press button circuit board and a light guiding board installed underneath light-pervious press buttons, wherein peripheries of the light guiding board are pasted with light emitters. Light can be uniformly distributed and transmitted in an interior of the light guiding board, and penetrate out from the light-pervious press button circuit board and press buttons, when the light emitters emit light. The light penetrated out has a good brightness and uniformity. In addition, a control circuit is used to dynamically control lighting display, such as an on/off, brightness, and color, to the light emitters.
