Problems solved by technology

[0010] Also, the electrodeless lighting system according to the prior art includes a cylindrical waveguide installed between the magnetron 2 and the resonator 6 to guide the transmission of microwaves, so that the overall volume of the system increases as much as as big as a waveguide
Therefore, existing technologies have limitations in providing portable products

Abstract

An electrodeless lighting system is disclosed, comprising: a microwave generator for generating microwaves; a microwave resonator, the microwave resonator includes a cavity matched with the microwave generator, and an LC resonant circuit composed of an inductance coil and a capacitor, Therefore, the microwave can be captured inside the cavity and resonate with the LC resonant circuit; and a light emitting unit connected with the cavity can use the resonant microwave to form a plasma region to emit light.

Description

technical field [0001] The invention relates to an electrodeless lighting system using microwaves. Background technique [0002] In general, an electrodeless system is a lighting device that can be used to provide good irradiance intensity without the use of electrodes, in which microwaves generated from a microwave generator such as a magnetron form a plasma using a luminescent material within the bulb , thereby emitting continuous light. [0003] figure 1 Shows a cross-sectional view of an electrodeless lighting system according to the prior art. [0004] refer to figure 1 , in the electrodeless lighting system according to the prior art, a magnetron 2, a transformer 3, a waveguide and other components are installed in the casing 1, and a bulb 5 and a resonator 6 are arranged outside the casing 1 . Therefore, the microwave generated from the magnetron 2 is guided to the resonator 6 by using the waveguide, so that the luminescent material inside the bulb 5 forms a plas...
