Disclosed are methods and devices for providing circadian-friendly LED light sources. A light source is formed to include a first LED emission (e.g., one or more LEDs emitting a first spectrum) and a second LED emission (e.g., one or more LEDs emitting a second spectrum), wherein the first and second LED emissions are combined in a first ratio and in a second ratio such that while changing from the first ratio to the second ratio, the relative circadian stimulation is varied while maintaining a color rendering index above 80. 일주기성-친화적 LED 광원들을 제공하기 위한 방법들 및 장치들이 개시된다. 광원은 제 1 LED 방출(예를 들어, 제 1 스펙트럼을 방출하는 하나 또는 그 초과의 LED들) 및 제 2 LED 방출(예를 들어, 제 2 스펙트럼을 방출하는 하나 또는 그 초과의 LED들)을 포함하도록 형성되고, 제 1 및 제 2 LED 방출들은 제 1 비율에서 제 2 비율로 변화하는 동안, 관련 일주기성 자극이 80 초과의 연색 지수를 유지하면서 변화하도록 제 1 비율 및 제 2 비율로 결합된다.
