Description
technical field [0001] The invention relates to the lighting field, in particular to a multi-frequency hopping low-frequency electrodeless lamp power supply drive module. Background technique [0002] As we all know: at present, the electricity consumption in the lighting field accounts for 25% of the total electricity consumption. The main lighting lamps include incandescent lamps, fluorescent lamps, and high-pressure gas lamps. Low efficiency and short service life. However, the electrodeless lamp, which stands out in the field of "green lighting" in the 21st century, has gradually entered our daily life with its characteristics of high luminous efficiency, high color rendering, long life, no flicker, energy saving and environmental protection, shockproof, and minimal maintenance. . [0003] There are currently 2 types of electrodeless lamps: high frequency and low frequency. The working frequency of the high-frequency electrodeless lamp is 2.65MHZ. Since the high-frequ...
