The most common plasma lamps are spherical or cylindrical. Although there are many varieties, it is usually a clear glass sphere filled with a mixture of various gases - most commonly helium and neon, and sometimes low-pressure xenon and krypton (less than 0.01 atmospheres), A high-frequency high-voltage alternating current (35kHz, 2 - 5kV) is supplied by a high-voltage transformer.
2.45GHz microwave energy (same as household microwave oven) is used to excite the luminescent substance in the quartz bulb, so that it generates molecular radiation and emits continuous visible light. The light efficiency is further improved and the reliability is enhanced. The cost is reduced, and the product is developed in the direction of miniaturization and low power. The microwave plasma lamp is an energy-saving and environmentally friendly lighting source with independent intellectual property rights.
