The non-stage regulated sunlight lamp circuit is shown in the figure, which consists of the regulated circuit, high frequency oscillator and filament transformer. The regulated circuit consists of the two-way thyristor VTH, two-way trigger diode VDH and the resistance-capacitance phase-drifting circuit. By regulating the potentiometer, the conducting angle of the thyristor VTH can be changed, which makes the DC voltage on the two terminals of the sunlight lamp change, so that the aim to regulate the light of the lamp is achieved. VT1 must be the Ge intermediate triode of 3AX818 type, β≥60, Iceo would better be low.
