摘要:
A voltage control startup circuit for a lighting ballast includes first and second transistors for converting direct current from a voltage source into alternating current to operate a lamp. The circuit includes an input portion for receiving a bus voltage signal, a resonant load portion for receiving a lamp load. The ballast also includes a start-up portion that delays firing of the lamp based on the detected bus voltage.

Disclosed are a lamp igniter module and method of assembling a lamp igniter module. The lamp igniter module comprises a transformer carrier, a slide-in electrical connector, a pc board, and a housing. Assembly of the lamp igniter module is accomplished by initially inserting a transformer carrier assembly within the housing and subsequently installing a slide-in electrical connector which may or may not be attached to the pc board.
