ILLUMINATED ROTARY CONTROL FOR A COMMUNICATION DEVICE

摘要

A rotary control (120) is illuminated through a controlled illuminated indicator provided by a light guide arc reflector (114) disposed on a control panel (104) along an outer periphery of a rotary control knob (112). The controlled illuminated indicator concurrently indicates status and location of the rotary control knob. The controlled illuminated indictor generates an increased rotational arc of illumination in response to the knob being rotated in a first direction and generates a decreased rotational arc of illumination in response to the knob rotated in a second direction. The rotary control (120) utilizes a helix slider (304) to control upwards and downwards movement of a reflector shield (302) which block and unblocks light rays in response to the knob (112) being rotated.

主权项

1. A rotary control interface for a communication device, comprising:
a light source for generating light rays; a light guide for reflecting light rays; a reflector shield for controlling shielding and unshielding of the reflected light rays; a helix slider coupled to the light guide, the helix slider having a helical slide within which to rotate the reflector shield; a knob for rotating the reflector shield along the helix slider while concurrently controlling a feature of the communication device; and a light guide arc reflector providing an illuminated indicator of the location of the knob and a current status level of the feature in response to rotation of the knob.
