Devices including reflective geometries for displays and lighting applications

Abstract

Devices having a reflective geometry are provided. The device includes a color conversion layer including luminescent material. The color conversion layer having a first side and a second side and a substrate having a first side and a second side. The second side of the color conversion layer located on the first side of the substrate. The device including an LED light source located remotely from the color conversion layer where the LED light source is optically coupled and / or radiationally connected to the first side of the color conversion layer. The device includes at least one of: (a) the substrate has a reflectivity of at least 20%, (b) a reflective layer located between the substrate and the color conversion layer, or (c) a back reflective layer located on the second side of the substrate. The devices are especially useful for lighting and display applications. Articles including the device are also provided.
