摘要： 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.

摘要： There is provided an apparatus for wavelength conversion, comprising a wavelength converter, a first reflector, a second reflector, a third reflector, and a first lens. The first reflector has a curvature and is configured to reflect a plurality of input light beams onto the second reflector. The second reflector is configured to reflect the input light onto the third reflector. The first lens is disposed between the wavelength converter and the third reflector. The third reflector is configured to reflect the input light through the first lens and onto the wavelength converter, which is then excited to emit an emitted light. The first lens is configured to receive at least a portion of the emitted light, reduce its divergence, and at least partially transmit it to form an output light propagating towards the third reflector, which is configured to at least partially transmit the output light.
