Low voltage bulb used in 220V power Generally,the low-voltage light bulbsneeds a transformer when it is supplied by 220v AC power, then the volume increases, prices are high. If the low-voltage lamps and a suitable capacitor connect in series, they could access 220V power supply directly. According to figure 9, themethod is simple and easy, such as the installation of lights in the turning-lathe. Capacitors in series have the effect of reducing voltage. Thecapacitance should be appropriate, or burned out light bulbs when over, or the lighting is too dark when too small. It can be determined according to the experiment. Its estimating formula C = 15I (μF), I is the rated current of low-voltage lamp. In addition, the value of the capacitor voltage is greater than 300V.
