Why can't the energy-saving light be dimmed?
For energy-saving lamp tube is high pressure ionization conduction gas lamp poles to work properly, must use high nonlinear pulse circuit, a stable voltage to work properly! Voltage regulator is to reduce the voltage, the lights dimmed some voltage will reduce, will not be able to stable voltage, lamp can appear stroboscopic, appropriate adjustment of 175 ~ 220 v can work normally, can adjust the voltage of 175-220 - v can be dimming energy-saving lamps, is a little change!
Just slightly dark, this can't be most people use requirements, may appear immediately below the 175 v stroboscopic, can continue to lower voltage time will slowly dimmed, but flicker frequency, by the time limit and then go out... This is the concept that experience teaches us, and we need to be able to test the verification by using the multimeter test, and we can specify the voltage value data! Because each lamp's high voltage pulse circuit the internal double tube push-pull the high voltage transistor physical data B amplification value is different! It doesn't have the same range of pressure as linear resistance tungsten filament lamp, which can work in 100-230v...
The energy-saving lamp is the principle of gas discharge luminescence, which can be used to adjust the light by regulating the current of the lamp. The general dimmer is used to control the width of the ac power supply, so that the current can be adjusted directly, and the current of the lamp is affected theoretically. But a simple thyristor would produce a shock wave and burn the energy-saving light circuit. So the standard dimmer is not available on the average energy-saving lamp. Specially designed energy-saving lamps can be used in general dimmers. A specially designed dimmer can also be used to light up a typical energy-saving lamp. But because of the high cost, there is not much to see.
