Led lighting devices with quantum dot glass containment plates

A lighting device 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, wherein:

• 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 comprises opposing glass panels that are sealed at complementary edges to define an interior volume;
• the quantum dot distributed color conversion medium is contained within the interior volume of the quantum dot glass containment plate;
• 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;
• the light source encapsulant comprises a primary distributed color conversion medium;
• the color conversion medium of the quantum dot glass containment plate defines a supplemental emission field of the lighting device;
• and
• the emission field defined by the primary distributed color conversion medium is spatially congruent with, but spectrally distinct from, the supplemental emission field defined by the quantum dot glass containment plate.
