Abstract
A refrigerated display case for maintaining food product at a desired temperature includes a product display area adapted to support and to display the food product such that the food product is accessible from the front of the case through an opening. An interior top wall is positioned above the product display area and includes an outlet adjacent the opening. An air passageway internal to the case and in fluid communication with the outlet permits refrigerated air from a refrigeration system to be supplied to the product display area through the outlet. The air discharged from the outlet defines an air curtain adapted to maintain the food product at the desired temperature. A light source is disposed adjacent the interior top wall and inside the air curtain and is adapted to illuminate the food product within the product display area.
