ABSTRACT:
An observable optical lamp status display system is provided for an ultraviolet irradiation lamp concealed from view. An external lamp status display panel that is within the field of view of an observer registers the operating status of each ultraviolet light irradiation lamp in an array of irradiation lamps. A separate fiberoptic lamp status display filament extends between each ultraviolet radiation lamps and the display panel. The lamp status display filament has a first end terminated in optical communication with the ultraviolet lamp and an opposite end that terminates in the lamp status display panel. An observer can determine whether or not a lamp is operating simply by observing whether or not light emanates from the end of the lamp status display filament in the display panel for each lamp operated.
