LIGHT WEIGHT AUTOMOTIVE HID IGNITER

摘要

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, multilayer 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).
