Abstract
A strobe light circuit adapted for use with a battery including a transformer and oscillator connected to charge a storage capacitor disposed across a discharge tube. A fourth winding in the transformer provides the trigger signal to the tube. By this arrangement the trigger pulse becomes progressively higher with increasing charge on the storage capacitor utilizing to best advantage the parameter relationships of the tube.
Claims4
