Abstract
The present invention is directed to providing a load control circuit for non-linear or negative-resistance loads, such as gaseous-discharge lamps, having improved cost-effective control and control. In accordance with exemplary embodiments, a controlled start feature is provided which is relatively cost-effective to implement and manufacture. Further, by reducing the complexity and costs associated with such functionality, additional functionality can be provided without substantially increasing the cost of the control circuit.
