摘要： A lighting device includes an output adjustment circuit, a smoothing circuit and a control circuit. The smoothing circuit receives a binary rotation detection signal according to the rotation of a fan and smooths the rotation detection signal to produce a smoothed signal. The control circuit detects a rotation malfunction of the fan when the smoothed signal is greater than or equal to an upper limit threshold over first predetermined time or when the smoothed signal is smaller than or equal to a lower limit threshold over second predetermined time.

摘要： A lighting device for a motor vehicle has a ventilating device for ventilating the interior of the lighting device. The ventilating device has at least one separate component which is connected to a lower housing wall of the lighting device in the region of a ventilation opening in the housing wall, and through which component external air can pass into the interior. The component is embodied as an air-guiding element by which a slip stream can be selectively deflected from the outside onto at least one specific partial region of a lens of the lighting device. The ventilation and therefore the demisting of the lighting device is significantly improved.
