Heat Transfer Analysis of a Lamphouse from a Typical Color Photographic PrinterToy, William A. 01 October 1981 (has links) (PDF)
High-speed operatorless photographic printers require high illumination levels at the negative print gate from lamps with stable color temperatures. The lamps using in these applications give off a large amount of heat radiation that is harmful to photographic emulsions as well as printer components and must be removed. This report describes how a typical photographic printer lamphouse separates the visible energy from the infrared, delivers the visible energy to the negative to be printed, and removes the infrared energy from the housing. This report also develops a set of empirically derived equations, which analytically describe the cooling mechanisms. These equations are intended to be useful design tools in future printer lamphouse development.
