Abstract

A wireless device lighting system provides backlighting of a display ( 104 ) and/or a user interface ( 1526 ) of a wireless device ( 100 ). A user interface ( 1526 ) includes a plurality of buttons ( 112 ) for entering information and at least one multicolor LED for emitting light. The at least one multicolor LED is located behind the plurality of buttons ( 112 ). The user interface ( 1526 ) further includes a connector for connecting the user interface ( 1526 ) to the wireless device ( 100 ) and a circuit board for mounting the at least one multicolor LED and the connector. The user interface ( 1526 ) further includes a light pipe for allowing light emitted from the at least one multicolor LED to be emitted from the buttons ( 112 ), the light pipe located between the at least one multicolor LED and the buttons ( 112 ). The user interface ( 1526 ) further includes a selector for allowing a user to define a color of light for emission by the at least one multicolor LED.

Claims (21)

1. An interface for coupling to a wireless device, comprising:

a plurality of buttons for entering information;

a circuit board disposed behind the plurality of buttons;

at least one multicolor LED disposed on the circuit board;

a connector disposed on the circuit board for connecting the interface to the wireless device; and
