摘要： PROBLEM TO BE SOLVED: To provide an AC delay angle control for lamp activation. SOLUTION: A control circuit for a lamp (120) is provided. The control circuit is used in conjunction with an alternating current (AC) variable voltage power supply. The control circuit includes a voltage sensing component for sensing the voltage of an input voltage signal from the power supply (102) for the lamp activation. The control circuit includes a controller (122) configured to estimate a delay angle as a linear function of the sensed voltage. The control circuit includes an AC converter (124) for modifying the input voltage signal according to the estimated delay angle to generate an AC voltage output signal having a constant effective voltage for the lamp activation.

摘要： A circuit (300) for igniting a high intensity discharge (HID) lamp comprises input terminals (302,304), output terminal (306,308), a charging circuit (R IGN ,C IGN ), a transformer (320) having a primary winding (322) and a secondary winding (324), a MOSFET (340), and a clamping diode (D CLAMP ) - . During operation, ignitor circuit (300) provides a high voltage (V IGN ) for igniting an HID lamp. Ignitor circuit (300) provides an ignition voltage (V IGN ) having a peak magnitude that is more predictable and less prone to degradation due to the influences of parasitic components. Additionally, ignitor circuit (300) may be realized in a manner that is significantly more cost-effective than comparable prior art circuits.
