Abstract

An electrodeless lighting system having a resonator with different aperture ratio portions, the electrodeless lighting system comprises: an electrodeless bulb for emitting light by plasmarizing light emitting materials filled therein; and a cylindrical resonator receiving the electrodeless bulb in an inner space thereof and having light transmission holes adapted to shield microwaves, which have been generated from a microwave generator and then applied to the inner space, from being discharged to the exterior, and transmit light emitted from the electrodeless bulb. Wherein, the resonator comprises: a low aperture ratio portion having a low aperture ratio extended from a certain region of a circumferencial direction of the resonator in a height direction of the resonator such that a relatively small amount of microwaves could be leaked; and a high aperture ratio portion having a relatively high aperture ratio as compared to the low aperture ratio portion, the high aperture ratio portion formed at the rest region of the circumferencial direction of the resonator such that a great amount of light emitted from the electrodeless bulb could be transmitted to the outside of the resonator.

Description

[0001] This application relates to the subject matter contained in the prior Korean application No. 10-2005-0090817 filed on September 28, 2005, and the entire content of the application is incorporated herein by reference. Technical field [0002] The present invention relates to an electrodeless lighting system including resonators having parts with different aperture ratios, and in particular to such an electrodeless lighting system including resonators having parts with different aperture ratios, which prevents microwaves from leaking from the resonator , It is possible to suppress interference between the electrodeless lighting system and peripheral equipment due to microwave leakage. Background technique [0003] 1 is a cross-sectional view showing the structure of a prior art electrodeless lighting system, FIG. 2 is a schematic diagram showing the connection structure between the waveguide and the resonator, and FIG. 3 is a diagram showing the application of the electric fi...
