Patent ID: 7583029

Claim:
A high temperature operation type electrodeless bulb for a plasma lighting system, comprising: a luminous unit that defines a space in which luminous materials are received, the luminous materials comprising sulfur in which triatomic sulfur molecules are decomposed into diatomic sulfur molecules, wherein the luminous unit comprises a low emissivity glass having selective permeability that transmits visible light generated by the luminous unit and that reflects infrared rays back into an interior of the luminous unit so as to maintain a temperature of the interior of the luminous unit at a predetermined high temperature level, wherein the predetermined high temperature level is a temperature at which the luminous materials received in the luminous unit are maintained in an excited state and the triatomic sulfur molecules are decomposed into diatomic sulfur molecules so as to decrease a corresponding shading effect caused by the triatomic sulfur molecules; and a supporting unit that extends from the luminous unit to a predetermined length so as to support the luminous unit within a plasma lighting system in which it is configured to be installed.
