Abstract: In the quest for mechanisms to improve the light
extraction efficiency and luminous efficacy of solid state lighting,
the remote phosphor concept has emerged as a potential solution.
Such a concept consists in bringing the phosphor element at a
remote location from the LED chip. Early, this technology was
propelled by two premises: a) it allows the phosphor to operate at
a lower temperature and, therefore, increases its conversion
efficiency; and b) it allows backscattered light to be redirected
towards the target. This paper addresses the first premise by
experimentally comparing the operating phosphor temperature
in the intimate and remote phosphor configuration applied to the
light engine approach. Results show that, for the topologies
tested, the phosphor operates at a lower temperature in the
remote phosphor configuration than in the intimate phosphor
