Abstract

A lighting device is provided comprising a chip-on-board (COB) light emitting diode (LED) light source, a light source encapsulant, a quantum dot distributed color conversion medium, and a quantum dot glass containment plate. The COB LED light source comprises at least one LED and defines a light source encapsulant cavity in which the light source encapsulant is distributed over the LED. The quantum dot glass containment plate is positioned over the light source encapsulant cavity and contains a quantum dot distributed color conversion medium. The distributed color conversion medium comprises a quantum dot structure and is distributed in two dimensions over an emission field of the lighting device within the quantum dot glass containment plate.
