Abstract

Solid state lighting devices with melatonin suppression characteristics that ameliorate or reduce symptoms of circadian rhythm disorders or other health conditions. Aspects disclosed herein additionally relate to providing one or more of the foregoing effects while maintaining color rendering index (CRI) values acceptably high for the intended use, as well as providing lighting devices with high luminous efficacy and enhanced energy efficiency. A solid state lighting device includes one or more solid state emitters and one or more lumiphoric materials that provide aggregated emissions of the solid state lighting device. The aggregated emissions have a warm correlated color temperature (CCT) with a color point that is off of the blackbody locus (BBL) by a certain distance.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Patent Application Serial No. 15 / 994,483, filed May 31, 2018, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to solid state lighting devices, including devices having phosphors arranged to be excited by electrically active solid state emitters, and related methods of making and using such devices. Background technique [0004] Solid state lighting devices, such as light emitting diodes (LEDs), are increasingly used in consumer and commercial applications. Advances in LED technology have produced efficient and mechanically robust light sources with long lifetimes. As a result, modern LEDs have enabled a variety of new display applications and are increasingly used in general lighting applications, often replacing incandescent and fluorescent light sources. [0005] LEDs are solid-state devices that convert elec...
