Apparatus and methods for illuminating display panels of electronic devices

摘要

An example electronic device includes a printed circuit board having a first row of light sources coupled to a first surface of the printed circuit board and a second row of light sources coupled to a second surface of the printed circuit board; a panel having a plurality of visual indicators; an first housing having a first row of chambers each having a first opening to receive one of the first row of light sources and a second opening to communicate light from the one of the first row of light sources to one of the visual indicators; and a second housing having a second row of chambers each having a third opening to receive one of the second row of light sources and a fourth opening to communicate light from the one of the second row of light sources to a second one of the visual indicators.

主权项

1. A printed circuit board, comprising:
a tab having an end to be inserted into a slot of a housing; a first light source located a first distance from the end at a first position corresponding to a first chamber of a first panel of the housing, the first light source being mounted to a first surface of the printed circuit board; and a second light source located a second distance greater than the first distance from the end at a second position corresponding to a second chamber of a second panel of the housing, the second light source being mounted to a second surface of the printed circuit board opposite the first surface.
