Abstract

Solid-state lighting devices and more particularly light-emitting devices for horticulture applications are disclosed. Light-emitting devices are disclosed with aggregate emissions that target chlorophyll absorption peaks while also providing certain broader spectrum emissions between the chlorophyll absorption peaks. The aggregate emissions may be provided by light-emitting diodes (LEDs) that emit wavelengths that correspond with certain chlorophyll absorption peaks and lumiphoric materials that provide broader spectrum emissions. The aggregate emissions are configured to have reduced emissions from lumiphoric materials in ranges close to certain chlorophyll absorption peaks, such as above 600 nanometers (nm). In this regard, light-emitting devices according to the present disclosure provide the ability to efficiently target specific chlorophyll absorption peaks for plant growth while also providing suitable lighting for occupants in a horticulture environment.
