Abstract

Abstract A high efficiency lamp apparatus for producing a light beam of polarized light includes an electrodeless lamp body that defines a chamber. A gas is contained within the chamber such as sulfur or selenium or a compound thereof that can be excited to form a plasma. Electrodes are positioned externally of the lamp chamber for producing radio frequency energy that excites the gas, forming a plasma light source of intense heat that emits a light beam. Electrodes are not subjected to the intense heat generated by the plasma as they are placed externally of the lamp body. A reflector is positioned next to the lamp body for redirecting some of the light emitted by the light source back to the lamp using the reflector so that the lamp reabsorbs light energy to intensify the light source. The reflector includes a polarizing filter that is positioned to receive and polarize the light beam. An insulator prevents heat intensity of the plasma from damaging the polarizing filter as it has a low operating temperature range.
