Embodiment Construction

[0015] exist figure 1 figure 2 In the middle, the high-frequency electronic generator (1) self-excited oscillation circuit switch generates a high-frequency signal output, which is loaded to the induction coil through the high-frequency shielding wire to generate a high-frequency magnetic field, which excites the ionization of the gas in the glass bulb (3), causing the phosphor to emit visible light. Since the power coupler (2) works in the inner cavity of the glass bulb (3), the induction coil (6) and the magnetic core (7) generate a large amount of heat, because the magnetic core (7) is immersed in the fluid (8) , the induction coil (6) and the magnetic core (7) generate a large amount of heat to directly heat the fluid (8), and quickly transmit the heat to the cooling device (4) through the convective heat transfer mode of the fluid to dissipate heat to the outside, ensuring that the induction coil (6 ) and the temperature of the magnetic core (7) will not be too high, t...

Abstract

The invention provides a high-frequency electrodeless lamp, comprising a high-frequency electronic generator (1), a glass blister (3) and a power coupler (2) which is arranged in the inner chamber of the glass blister (3); fluid body is filled in the power coupler (2); one end of the fluid is contacted with a heat dissipation device (4); the heat quantity generated when the power coupler (2) works is transferred to the heat dissipation device (4) via the fluid body filled in the power coupler and the heat dissipation device releases heat quantity to the outside world, ensuring that the power coupler works in a reliable temperature range. The technique adopted in the invention reduces power consumption, lowers cost, improves heat dissipation efficiency, prolongs service life and can manufacture high-power high-frequency electrodeless lamps.
