Abstract
According to the present specification there is provided a rotatable heat sink device which comprises a heat sink configured to enclose a cooling fluid, and the heat sink is rotatable about a rotational axis. The heat sink, in turn, comprises a first portion configured to receive thermal energy from a source external to the heat sink, and a second portion configured to dissipate at least a portion of the thermal energy to surroundings external to the device. The device further comprises an optical wavelength conversion material disposed on an outside surface of the first portion of the heat sink, and an agitator disposed inside the heat sink. The agitator is rotationally independent of the heat sink and is configured to promote circulation of the cooling fluid between the first portion and the second portion.
