Abstract

The invention relates to a secondary inductively coupled plasma electrodeless lamp, comprising a secondary inductively coupled strip lamp, a coupler and a starting device, wherein the secondary inductively coupled strip lamp is provided with only one closed loop, the closed strip lamp penetrates through the coupler twice to form a two-turn secondary, the starting device is amalgam, and the amalgam is arranged on a bridge pipe of the secondary inductively coupled strip lamp and is near to the coupler. The invention aims at providing an inductively coupled plasma gas discharge lamp structure of which the electrodeless strip lamp is coupled twice, reducing the starting voltage of the electrodeless lamp, and improving the coupling coefficient and conversion efficiency of the electrodeless lamp.

Description

technical field [0001] The invention belongs to a light-emitting device, which belongs to an electrodeless secondary induction coupling plasma gas discharge lamp. Background technique [0002] The inductively coupled plasma gas discharge lamp coupler generally adopts a transformer structure. The high-voltage insulated wire is wound on the magnetic core to form the primary of the transformer. The lamp tube passes through the center of the magnetic core to form the secondary of the transformer. The AC signal output by the ballast is loaded on the transformer. Primary, which couples electromagnetic energy to the lamp (secondary) via a magnetic core. Usually, the lamp can only pass through the coupler once, and the coupling is performed only once, and the coupling coefficient is low, resulting in low conversion efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a secondary inductively coupled plasma electrodeless lamp structure. ...
