Abstract
A light color changeable illuminated keyboard includes a circuit layer, plural keys, a switching key, a bicolor light-emitting element and a control unit. The plural keys and the switching key are disposed on the circuit layer. The bicolor light-emitting element is located under the plural keys. The bicolor light-emitting element selectively emits a first color light or a second color light. The control unit is electrically connected with the switching key and the bicolor light-emitting element. If the switching key is pressed down when the bicolor light-emitting element emits the first color light, a pressing signal is generated. In response to the pressing signal, the color light emitted by the bicolor light-emitting element is switched from the first color light to the second color light under control of the control unit.
