| Abstract: Solid state lighting devices and methods for heat dissipation with rotary
cooling structures are described. An example solid state lighting device
includes a solid state light source, a rotating heat transfer structure
in thermal contact with the solid state light source, and a mounting
assembly having a stationary portion. The mounting assembly may be
rotatably coupled to the heat transfer structure such that at least a
portion of the mounting assembly remains stationary while the heat
transfer structure is rotating. Examples of methods for dissipating heat
from electrical devices, such as solid state lighting sources are also
described. Heat dissipation methods may include providing electrical
power to a solid state light source mounted to and in thermal contact
with a heat transfer structure, and rotating the heat transfer structure
through a surrounding medium. |
