D. C. Powered control circuit for energizing a cold cathode lamp

摘要

A control circuit including digital circuitry and a voltage step up transformer is arranged to operate as an inverter to provide for energizing a cold cathode lamp under power provided by a d.c. source such as a battery. According to a significantly preferred feature, any one of a plurality of operating modes can be manually selected so that different illuminating effects can be provided as desired.
