Abstract

An electrodeless sensor light provided with a plurality of closed loops comprises an electrodeless discharge cavity (10) comprising a lamp shell which constitutes the closed loop, and the lamp shell is filled with mercury vapor and inert gas, at least one transformer core (2) which is placed with surrounding the lamp shell, at least one coil winding (3) arranged on the transformer core (2) and connected with an RF power supply (1). The invention is characterized in that the lamp shell is at least provided with two closed loops (6, 7, 8 and 9). The invention can be used for constructing a plurality of styles of electrodeless discharge lamps and the device of the invention has the advantages of easy start-up, easy realization of output with large power, etc.

Description

technical field [0001] The present invention relates to discharge lamps, in particular to electrodeless induction discharge lamps. Background technique [0002] Such a discharge lamp is known from Chinese Patent No. 96191079.8. This kind of discharge lamp includes: an electrodeless discharge chamber, which includes a tubular lamp envelope filled with mercury and inert gas, and the lamp envelope forms a closed loop; at least one transformer is arranged around the lamp envelope iron core; coil windings are arranged on the transformer iron core; a radio frequency power supply connected to the coil windings is used to supply sufficient high-frequency energy to the mercury vapor and the inert gas to generate A discharge with a discharge current equal to or greater than 2A; and wherein the frequency of the radio frequency power source is in the range of 50KHz to 3MHz. In this kind of discharge lamp, the lamp housing has only one closed loop, which makes the structure and shape o...
