US 7,126,282 B2 · Electrodeless lighting system

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.

Dependent claims

An electrodeless lighting system, comprising:

a waveguide that guides microwave energy generated by a microwave generator;
and
a resonator, formed in a mesh structure, that allows the microwave energy guided by the waveguide to resonate therein and passes light emitted by a bulb positioned in the resonator, the resonator comprising a perforated microwave leakage preventer, disposed around the bulb, having a perforation per unit area ratio lower than a perforation per unit area ratio of a part of the resonator located above the microwave leakage preventer, such that microwave energy is concentrated on the bulb.
