  • Transporting light within circuit board profile
    Patent number: 11598911
    Abstract: Embodiments described herein relate to a system for positioning indicator lights of a network device. The system may include a circuit board, which may include a circuit board edge positioned behind a front panel of the network device, two surfaces; and a side of the circuit board edge positioned between the two surfaces. The system may also include a hole through the circuit board near the circuit board edge, a cutout extending from a portion of the hole to the side of the circuit board edge, a LED coupled to the surface of the circuit board and adapted to emit light into the hole, and a lightpipe disposed in the hole to receive light emitted from the LED into a first end of the lightpipe. The lightpipe may direct the light from a second end of the lightpipe toward an opening in the front panel of the network device.
