SOLID STATE LIGHT FIXTURES SUITABLE FOR HIGH TEMPERATURE OPERATION HAVING SEPARATE BLUE-SHIFTED-YELLOW/GREEN AND BLUE-SHIFTED-RED EMITTERS

摘要

Solid state light fixtures include a plurality of blue-shifted-yellow/green light emitting diode (“LED”) packages and a plurality of blue-shifted-red LED packages, where the solid state light fixture emits light having a correlated color temperature of between 1800 K and 5500 K, a CRI value of between 80 and 99, a CRI R9 value of between 15 and 75, and a Qg value of between 90 and 110 when the blue-shifted-yellow/green LED packages and the blue-shifted-red LED packages are operating at steady-state operating temperatures of at least 80° C.
