Abstract
A water-cooled low pressure gas or mercury vapor lamp which utilizes a cooling system to keep the lamp cool in the area where useful radiation is emitted. This is accomplished by means of a cooling chamber directly adjacent to the gas or mercury vapor discharge chamber. A cooling fluid is injected into the cooling chamber through a cooling inlet and exits the cooling chamber through a cooling outlet after traveling the cooling chamber's entire length. The cooling fluid removes the heat generated by the radiation and allows the useful emission to be optimized.
