Solid state lighting devices and methods with rotary cooling structures
| DWPI Title: Solid-state lighting device used for residential, commercial or industrial application has mounting assembly with stationary portion configured to remain stationary with respect to heat transfer structure during operation of device |
| 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. |
| Use: Solid-state lighting device used for residential, commercial or industrial application. |
| Advantage: Offers rotary-cooled, energy-efficient and inexpensive solid-state lighting device. Improves efficiency of LED bulbs. |
| Novelty: The solid-state lighting device (202) has a heat transfer structure (204) in thermal contact with a solid-state light source e.g. LED (208), and rotates through a surrounding medium during operation of the device. A mounting assembly (203) is rotatably coupled to the heat transfer structure and has a stationary portion (205). The stationary portion is configured to remain stationary with respect to the heat transfer structure during operation of the device. |
