| 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. |
