Abstract
An illuminated push button, an illuminated instrument cluster for a conveyance, and a lighting system for a conveyance are discussed. The push button can include a light sheet mounted on a base portion, such that light from the LED chips in the light sheet travels away from the base portion. The illuminated instrument cluster can include a lens mask assembly; an appliqué disposed behind the lens mask assembly with translucent graphical information and optically transmissive diffusion material, a housing, a light sheet, and a printed circuit board configured to address and drive the light sheet material. The light active sheet material is mounted behind the appliqué, such that light from the LED chips travels through the graphical information of the appliqué. The lighting system includes a light sheet; and an adhesive disposed on the light sheet. The light active sheet material is formed as lighting for a conveyance.
