More Information
Summary:The utility model relates to a high-voltage direct current electrodeless lamp, which comprises a high-voltage direct current power source, a filter circuit, a high-frequency oscillating circuit, a coupler and a bulb. External input high-voltage direct current is subjected to filtering and smoothing with the filter circuit, is then transmitted to the high-frequency oscillating circuit, and is converted by the high-frequency oscillating circuit into high-frequency high voltage current transmitted to the coupler, and the coupler generates high-frequency alternating high magnetic field acting on the bulb to emit light. The filter circuit is a pi-type filter, and the oscillating frequency of the high-frequency oscillating circuit is 2.0MHz. The high-voltage direct current electrodeless lamp can be applied to all occasions powered by a high voltage direct current power source, extends use range of electrodeless lamps, and significantly contributes to energy-saving illumination and environment-friendly illumination.
