One thyristor incandescent dimming circuit


Posted on Mar 28, 2007

(1) using thyristor incandescent dimming circuit one circuit is shown in Figure 2-66. Figure 2-66 (a) using thyristor half- wave controlled dimmer and dimmer with diode approach.

When the switch SA hit when "3" position, the adjustment potentiometer RP, the voltage across the lamp varies from 20-100V; when SA hit the "2" position, the light bulb brightness light-emitting rated power of about 1/4; when SA hit the "1" bits set when, all light bulbs. Figure 2-66 (b) using only product thyristor dimmer, use rated voltage lloV bulb.
