Abstract
An electrodeless lighting system includes: a waveguide for guiding microwave energy generated from a microwave generator; and a resonator formed in a mesh structure allowing the microwave energy having passed the waveguide to resonate therein and passing light, and having around the bulb a microwave leakage preventing portion having a relatively low perforation ratio per unit area so that microwave energy is concentrated on the bulb positioned therein. Accordingly, leakage of microwaves is minimized and luminous efficiency is improved.
