The invention relates to a magneto-electric electrodeless lamp, which belongs to the technical field of the illumination lamp, and comprises a bulb body, an electromagnetic field generator, a power source and a lamp adapter, which forms a compact integral electrodeless lamp, wherein the electromagnetic field generator is arranged inside an inner space of a bulb body stern column, an electric wire tap of an inductance coil is respectively connected with the lamp adapter through the power source, and mixed gas is filled inside the bulb body. By adopting high-frequency crossed electric and magnetic field gas discharging principle, the bulb body emits light. The electromagnetic field generator generates quantizable electromagnetic field distribution and strength, normal glow discharge interval of gas quantity which is three times of the ordinary electrodeless lamp and a computable mixed gas are selected to configure, the nickel-zinc material with high magnetic conductivity and high Curie temperature is selected as main material of the electromagnetic field generator, and the integrated small-size power source is used, so the gas discharging is stable, the luminous efficiency is high, the temperature increase is low, and the service life is long. The diameter of the bulb body is small, and the mercury storage tube and the discharging tube inside the bulb body are integrated into one to have the mercury storage effect and the discharging effect, so the structure is simplified.

Description

AI Technical Summary

Problems solved by technology

Its main feature is the use of discharge tube multi-circle gas electric field superposition enhanced discharge principle and high-frequency high-voltage electric field coupling principle, which solves the problems of high frequency, high switching power consumption, high-frequency electromagnetic wave radiation pollution of the environment and various damages to electronic components in current electrodeless lamps. High performance requirements, high production costs, and problems that cannot be widely used

[0003] Although the above-mentioned existing electrodeless lamps have solved some technical problems to a certain extent, the following defects still exist: 1. the principle structure of coupling or electromagnetic induction is adopted, and the distribution and intensity of the electromagnetic field cannot be quantified; 2. the type and pressure of the gas are not properly selected, The discharge voltage is high or difficult to discharge; ③The discharge voltage is high, the temperature rise is large, and the radiator is an essential part; ④Due to the limitation of the magnetic resistance of the magnetic material used for coupling or electromagnetic induction, it is difficult to work normally without a radiator. It cannot meet the working environment requirements of -30°C ~ 50°C; ⑤The surface brightness of the existing electrodeless lamp is very poor due to the use of small power and large bulbs (civil use)
