    摘要: A light fixture includes a ballast and a plurality of lamps connected to the ballast in parallel. The ballast provides an output signal to the plurality of lamps as a function of a 1st steady state condition. When the ballast senses an end-of-life condition for a lamp of the plurality of lamps, the ballast increases the frequency of the output signal provided to the plurality of lamps until the lamp ceases to conduct current. When the lamp ceases to conduct current, the ballast decreases the frequency of the output signal to a frequency determined as a function of a 2nd steady state condition different from the 1st steady state condition. A total current of the 2nd steady state condition is proportional to a total current of the 1st steady state condition as a function of the number of lamps exhibiting an end-of-life condition.

    摘要: A ballast includes a rectifier, DC to DC converter, a dimming sensor, and a light source driver circuit. The rectifier provides rectified power from an AC power source modified by a chopper dimmer. The converter includes a boost inductor having a primary winding and a detection winding. The converter receives the rectified power from the rectifier and provides a DC power rail. The dimming sensor monitors a voltage of the detection winding of the boost inductor and provides a dimming signal as a function of the monitored voltage. The light source driver circuit receives the dimming signal, receives the DC power rail, and provides power from the DC power rail to the light source as a function of the dimming signal. An amount of power provided to the light source by the light source driver circuit corresponds to a dimming level indicated by the dimming signal.

    摘要: A wind turbine blade has a suction side shell member and a pressure side shell member. The shell members are joined along a leading and trailing edge from a root to a tip of the blade and defining an internal cavity of the blade. A pressure sensor is configured on at least one of the suction or pressure side shell members. The pressure sensor further includes a body mounted to an inner surface of the respective shell member within the internal cavity. A sensing element has a first side exposed to external air pressure through a passage in the respective shell member, and an opposite second side exposed to a reference pressure. Control circuitry within the body generates a variable output signal as a function of a pressure differential between the external air pressure and reference pressure experienced by the sensing element.
