Patent number: 7129639Abstract: An electrodeless lighting system includes a resonator which passes light. The resonator communicates with a waveguide which guides microwave energy generated by a microwave generator. The microwave energy forms an electric field in the resonator. The electrodeless lighting system further includes a bulb, positioned in the resonator, that generates light from the electric field, a first coil which is wound around an outer circumferential surface of the resonator, and a second coil which is wound around the outer circumferential surface of the resonator. The bulb is disposed between the first coil and the second coil, with the first coil and the second coil forming a magnetic field around the bulb. Accordingly, initial lighting can be more easily achieved, and if the intensity of the magnetic field is properly controlled, the total quantity of light is increased, thereby improving luminous efficiency of the bulb.Type: GrantFiled: January 19, 2005Date of Patent: October 31, 2006Assignee: LG Electronics Inc.Inventors: Hyun-Jung Kim, Joon-Sik Choi, Yun-Chul Jung, Yong-Seog Jeon, Seung-Yeup Hyun, Byeong-Ju Park, Ri-Na Hwang, Dae-Kyung Kim, Ji-Young Lee
