Abstract
A device that includes multiple light channels for separating the light from adjacent indicating lights and preventing bleed-over can be constructed to include an electrically conductive material so that the device can also serve as an EMI shield to reduce the amount of EMI escaping from a computer system chassis. By reducing light bleed-over from one indicating light to the next, such a device reduces the likelihood that a user will be confused about whether an indicating light is on or off. Additionally, closely spaced indicating lights can be accommodated by slots in the chassis while EMI is reduced by the shielding effects of the light channel device.
