Two gauge illumination with one light guide
DRIVE
August 17, 2016
A light guide assembly for illuminating two gauges utilizing a single light guide includes of a two pairs of light sources such as LEDs, OLED's, quantum dots or other useful light sources functioning to emit light in opposite directions. A light guide receives the light emitted by the LEDs and leaks light out of its open surfaces. A protrusion from the light guide which leaks light in a specific orientation depending on its geometry illuminates a second gauge. An opaque gauge which covers the main portion of the light guide and is located above the light guide.
