First Claim
Patent Images
1. A user interface assembly for a cooktop appliance, comprising:
- a cooking panel comprising a colored transparent material;
a first printed circuit board spaced apart from the cooking panel, the first printed circuit board comprising at least one light source;
a light transmissive layer disposed between the cooking panel and the first printed circuit board, the light transmissive layer comprising a support substrate having a first surface adjacent the cooking panel and a second surface adjacent the first printed circuit board; and
at least one light guide having an inner surface, the inner surface comprising an ink configured such that light from the light source reflecting off the inner surface of the light guide and subsequently passing through the light transmissive layer and the cooking panel appears a desired color to a user of the user interface assembly.

Abstract
The present invention provides a cooktop appliance with features for correcting the color of light passing through the cooking surface such that the light appears a desired color to a user of the cooktop appliance. More specifically, a colored or fluorescent ink may be applied to, or a colored or fluorescent dye incorporated into, one or more light guides of a user interface assembly such that reflecting off of the interior surface of the light guides and passing through the cooking surface appears a desired color to the user.
