Abstract
Use of a bi-color light source, a single light conduit and two color filters visually produce two status indications in an information handling system. The bi-color light source produces a blue color light when in a first state and an amber color light when in a second state. The blue color light passes through one of the color filters to a first portion of a single status indicator and the amber color light passes through the other color filter to a second portion of the single status indicator.
Claims27
An information handling system having a bi-color light source for indicating status thereof, said system comprising:
- a motherboard;
- an interface attached to and in electrical communication with said motherboard;
- a bi-color light source, said bi-color light source producing a first color light when in a first state and a second color light when in a second state;
- a first bandpass light filter, said first bandpass light filter substantially passing the first color light and substantially rejecting all other colors of light;
- a second bandpass light filter, said second bandpass light filter substantially passing the second color light and substantially rejecting all other colors of light;
- and
- a status indicator in light communication with said first and second bandpass light filters, wherein a first portion of said status indicator will be illuminated with the first color light and a second portion of said status indicator will be illuminated with the second color light.
An apparatus for indicating status, comprising:
- a bi-color light source, said bi-color light source producing a first color light when in a first state and a second color light when in a second state;
- a first bandpass light filter, said first bandpass light filter substantially passing the first color light and substantially rejecting all other colors of light;
- a second bandpass light filter, said second bandpass light filter substantially passing the second color light and substantially rejecting all other colors of light;
- and
- a status indicator in light communication with said first and second bandpass light filters, wherein a first portion of said status indicator will be illuminated with the first color light and a second portion of said status indicator will be illuminated with the second color light.
A method for indicating status, comprising the steps of:
- producing a first color light with a bi-color light source when the bi-color light source is in a first state;
- producing a second color light with the bi-color light source when the bi-color light source is in a second state;
- passing the first color light through a first bandpass light filter, the first bandpass light filter substantially rejecting all other colors of light;
- passing the second color light through a second bandpass light filter, the second bandpass light filter substantially rejecting all other colors of light;
- and
- illuminating a first portion of a status indicator with the first color light from the first bandpass light filter;
- and
- illuminating a second portion of the status indicator with the second color light from the second bandpass light filter.
