LAMP SYSTEM WITH CONDITIONED WATER COOLANT AND DIFFUSE REFLECTOR OF POLYTETRAFLUORETHYLENE (TPFE)

摘要

A lamp system (10) with a very soft high-intensity output is provided over a large area by water cooling a long-arc lamp (28, 30) inside a diffuse reflector (32, 34) of polytetrafluorethylene (TPFE) and titanium dioxide (TiO2) white pigment. The water is kept clean and pure by a one micron particulate filter (24) and an activated charcoal/ultraviolet irradiation system (23, 22) that circulates and deionizes and biologically sterilizes the coolant water at all times, even when the long-arc lamp is off.
