Abstract
Light collimators and methods for human machine interfaces are disclosed. An example human machine interface includes a top surface having a decorative element to be illuminated, a light source, and a plurality of parallel light collimators that collimate visible light emitted by the light source and direct the collimated light toward the bottom side of the decorative element. An example method of illuminating a decorative element of a human machine interface includes emitting light, passing the light through a plurality of collimators defined in the human machine interface, and directing the collimated light toward the decorative element.
