APPLICATION APPARATUS COMBINING LED DIMMER AND REACTOR

The invention discloses an electrical appliance of an LED dimmer working in conjunction with a line reactor, comprising a power supply, a dimming control circuit, a line reactor circuit and a voltage converting circuit. Output end of the power supply is connected to the dimming control circuit, output end of the dimming control circuit is connected to the line reactor circuit, output end of the line reactor circuit is connected to the voltage converting circuit, and output end of the voltage converting circuit is connected to electrical loads. In the present invention, a utility frequency line reactor is series connected between the output end of the dimmer and the dimmable LED light, and a R.C peak voltage absorption circuit is parallel connected to both ends of the line reactor. By switching the phase angle on and off, it is possible to adjust level of output voltage and make light adjustment. In the meantime, harmonic current is reduced, and consequently electric grid pollution and line loss relieved, and finally energy is saved and pollution is controlled.
