Abstract

System, method, and apparatus for two phase cooling in light-emitting devices are disclosed. In one aspect of the present disclosure, an apparatus includes a light-emitting device and a two-phase cooling apparatus coupled to the light-emitting device. The coupling of the two-phase cooling apparatus and the light-emitting device is operatively configured such that thermal coupling between the light-emitting device and the two-phase cooling apparatus enables, when, in operation, heat generated from the light-emitting device to be absorbed by a substance of a first phase in the two-phase cooling apparatus to convert the substance to a second phase.
