Light-guiding system for e.g. display and operating device, of portable mixer amplifier utilized for amplifying sound signal of e.g. microphone for speakers, has light conductors and spacer interconnected with each other in housing

摘要

The system has multiple optical fiber groups comprising multiple light conductors that are made from transparent material for lighting of LEDs i.e. surface mount device (SMD)-LEDs. A spacer is provided for adjustment of spacing between a circuitry carrier i.e. circuit board (12), and a front panel (2). A housing is made from non-transparent material for the light, and completely surrounds the light conductors in an intermediate space, where the light conductors and the spacer are interconnected with each other. The spacer is designed as a portion of the housing. An independent claim is also included for a display device for a portable mixer amplifier, comprising a circuitry carrier for controlling LEDs.
