Warm dimming and tunable light emitting devices

Abstract

A light emitting device for generating light of a color temperature that decreases with decreasing power applied to the light emitting device, the light emitting device comprising: a substrate; a first LED array of serially connected first LED chips on the substrate, a second LED array of serially connected second LED chips on the substrate, a first photoluminescence layer covering the first LED array for generating light of a first color temperature, a second photoluminescence layer covering the second LED array for generating light of a second different color temperature, and a linear resistor serially connected to the first LED array; wherein the first LED array and serially connected linear resistor, and second LED array are connected in parallel.

Dependencies are inferred from the claim text.
