Abstract: An optical device for a semiconductor based lamp comprises a semiconductor based light-emitting device and a light-redirecting member. The light-redirecting member has a reflective surface that redirects at least some of the light emitted from the semiconductor-based light-emitting device ambiently, away from the lamp, and into the surrounding environment in divergent lateral and at least partially downward directions, without further reflection. A frosted semi-transparent cover encloses the light-emitting device and light-redirecting member. A gap between the semi-transparent cover and an outer edge of the light-redirecting member passes some of the light emitted from the semiconductor-based light-emitting device upwardly into a surrounding environment.

Abstract: A wind turbine system includes a nacelle, a generator, a central control module, an impeller, a transmission module, a speed sensor module, a pitch angle driving module, a hub controller and a slip-ring apparatus. The hub controller receives a first pitch command from the central control module or generates a second pitch command according to a rotation speed of a hub sensed by the speed sensor module. If the first pitch command is correct, the hub controller transmits the first pitch command to the pitch angle driving module. If not, the hub controller transmits the second pitch command to the pitch angle driving module. The pitch angle driving module controls a pitch angle of at least one blade after receiving the pitch command, so that the wind turbine system works. Therefore, the wind turbine system has a distributed control function and a redundancy capability.
