With the development of electronic technology, practical electrodeless fluorescent lamps have developed rapidly in recent years. The existing products internationally are the Dutch QL type, with powers of 55W and 85W, a light efficiency of about 68lm/W, a lifespan of 60000 hours, and a working frequency of 2.65 MHz; Genura type electrodeless fluorescent lamp from the United States, with a power of 23W, a light efficiency of 48lm/W, a lifespan of 10000h, and a working frequency of 2.65MHz; The Japanese Every Light type electrodeless fluorescent lamp has a power of 9W and 27W, a light efficiency of 41lm/W, a lifespan of 40000 hours, and a working frequency of 15.56MHz; There are also Endura type electrodeless fluorescent lamps from Germany, with power of 100W and 150W, light efficiency of 80lm/W, lifespan of 60000 hours, and operating frequency of 250kHz. And the performance of China's emerging electrodeless fluorescent lamps in recent years has also reached the advanced level of international products of the same type, and has formed large-scale production and batch export According to incomplete statistics, in recent years, China has added nearly a hundred new production enterprises for electrodeless fluorescent lamps, and both production and application have become hot topics. Introduction to Electrodeless Fluorescent Lamps: Electrodeless fluorescent lamps have the advantages of high brightness, high efficiency, low power consumption, no flicker, small size, and long lifespan. Repeated startup performance is good, and can start instantly within 0.1 seconds. The chromaticity of three wavelength white light colors can meet different needs. The performance requirements for dual head fluorescent lamps are to use AC power frequency with starter operation and preheating cathode lamps with high-frequency operation. High resistance preheat resistive electrode and low resistance preheat cathode lamp (referred to as "fast start fluorescent lamp") that operate at an AC power frequency without a starter (without a starter). A preheating cathode lamp (referred to as a "high-frequency fast start fluorescent lamp") that uses high-frequency (power supply) operation. Non preheating cathode lamps using AC power frequency or high-frequency operation (referred to as "instantaneous start fluorescent lamps" or "high-frequency instantaneous start fluorescent lamps")
