hange of the bridge. Its trigger pulse VT1, VT2 and VT3 photosensitive tripolar equivalent resistance role played by the single crystal tube. When the projector lamp light because the power supply voltage changes, the change in resistance of the phototransistor, single-junction transistor control voltage phase also changed, so that the trigger pulse thyristor phase shift, increase or decrease the thyristor conduction time, L on the approximation of the voltage remains constant, the brightness of the lamp is also kept approximately constant, so that the light stability.
