Electrodeless lamp fixture

Abstract

The invention provides an electrodeless lamp fixture which comprises a lamp shade, an electrodeless lamp, a heat conduction metal rod, an excitation source, a main amalgam storage tube, an inner tube, a bulb glass shell, an excitation coil and an auxiliary amalgam, wherein the lamp shade is provided with a lamp holder; the electrodeless lamp is installed on the lamp holder and comprises a lamp opening which cooperates with the lamp holder; the heat conduction metal rod and the excitation source are installed on the lamp opening; a concave cavity is arranged between the inner tube and the heat conduction metal rod; the excitation coil is positioned in the concave cavity; the magnetic core of the excitation coil and the heat conduction metal rod form a socket joint; and the position of the auxiliary amalgam on the outer wall of the inner tube is the farthest away from the emergent surface of the lamp shade, so that the auxiliary amalgam is positioned at the highest point of the outer wall of the inner tube after the electrodeless lamp is installed on the lamp holder. The embodiment of the invention can ensure that the auxiliary amalgam is installed at the highest point of the outer wall of the inner tube, thus when the electrodeless lamp is started, hot gas ascends under the convection effect of gas, thereby ensuring highest temperature at the highest point. Therefore, the auxiliary amalgam is arranged in the position the temperature of which rises at the highest speed, thereby promoting mercury atoms to be evaporated out of the auxiliary amalgam so that the electrodeless lamp can be quickly started.

Description

technical field [0001] The invention relates to the field of design and manufacture of an electrodeless lamp, in particular to an electrodeless lamp lamp capable of realizing quick start. Background technique [0002] The electrodeless lamp is based on the principle of electromagnetic induction, which couples the plasma with the magnetic field lines of the circuit, and uses a pair of excitation coils set outside the lamp tube to form an induced current in the lamp tube, unlike ordinary fluorescent lamps, which use electrodes to convert external electrical energy. The energy required for the internal workings of the lamp. Since the electrodeless lamp has no electrodes, there are no vulnerable parts in the lamp tube, and the life of the whole system mainly depends on the electronic ballast, so the life of this kind of lamp is very long, which can reach more than 60,000 hours. It is especially suitable for places where it is difficult and expensive to change lamps and importan...
