Adjustable strobe with temperature stabilization

Claim 1

A strobe light circuit for flashing a flashtube at a desired rate and intensity comprising: a voltage source circuit including a first capacitor which is connected in parallel with the flashtube, the first capacitor providing the energy to fire the flashtube upon attainment across the first capacitor of a voltage corresponding to a predetermined threshold firing voltage; and a flash circuit connected across the voltage source circuit which includes a flashtube and a trigger circuit, the trigger circuit being operable to fire the flashtube to generate a light output upon the first capacitor charging to a voltage corresponding to the threshold firing voltage of the flashtube, the trigger circuit including a circuit means for ensuring that the flashtube is fired at virtually the same instant the voltage across the first capacitor exceeds the threshold firing voltage, the circuit means comprising a series resistor divider network which includes a thermistor for compensating for changes in the values of electrical elements in the strobe light circuit which may occur due to temperature changes, a potentiometer to allow for adjustments in the resistance of the series resistor divider network and a resistor.
