1.The basic model traic dimmer 2.The practical model traic dimmer 3.The minimum brightness adjustable traic dimmer In most cases, we hope the minimum brightness of the bulb will be stable after sw1 close-up, so access r2 in this circuit can achieve this purpose. If we change r2 to the variable resistor, the adjustment will be more accurate. 4.Withthe light-steady function dimmer When the ambient light changes, resistance value of cds will be change too, this value will be changes the conduction angle of traic, makes lamp1 changes the brightness in the opposite direction. And the rw2 is used to adjust the sensitivity of cds. 5.Stable adjustment dimmer 6.Dimmer of eliminate the lag effect
