Abstract of the Invention A simple, light weight air cooled filter arrangement for a high intensity narrow band pass filtered light fixture. In lighting fixtures such as infrared energy sources or stage lighting, it is necessary to filter a conventional broad spectrum energy source so that only energy in the desired region is transmitted. These filters which absorb energy in bands other than those being transmitted tend to become very hot particularly when high energy sources are required. A light fixture is provided having a plurality of spaced filters near a light output end. Each filter, except the outer most filter, has a portion of its outer periphery removed. These open areas are alternately positioned to form a tortuous air path between adjacent filters. A cooling fan draws filtered exterior ambient air through the tortuous paths between the filters and exits the warmed air past the energy source out the end remote from the filters. Sensors are provided for controlling the output of the energy source relative to exterior light and exiting air temperatures and the fan operation.
