ABSTRACT:
A light weight, bobbinless high voltage transformer and igniter module is provided that meets low-cost and high-reliability requirements for automotive HID products. A printed circuit board (112) serves as a carrier for low voltage electronic components. A high voltage bar core transformer (114) is held in a cradle (130, 130′) that accommodates potting material and has a channel (160) that receives a high voltage wire extending from the transformer for connection with a lead (104) of an HID lamp (100). Thin walls (210, 212) allow the cradle to serve as the cavity for the potting of the transformer. In addition, multi-layer dielectric material is disposed between the primary and secondary windings. Preferably, the primary winding (196) is a strap that covers a large surface area of the secondary winding (192).
