ABSTRACT:
A lamphouse for use with a photographic printer for controlling the exposure time of the additive primary colors in the lamphouse and thereby controlling the time of exposure of the light sensitive color print paper. The lamphouse includes a housing adapted to be positioned on the printer proximate the optical stage of the printer and defining a mixing chamber for directing light to the optical stage and a light generating assembly for delivering light to the mixing chamber. The light generating assembly is constructed as a plurality of structurally distinct modular subassemblies and the housing includes parallel side by side tracks to individually slidably receive each modular subassembly. Each modular subassembly is positioned in the housing and removed from the housing by sliding the modular subassembly along the respective track in the housing. As the modular subassembly is inserted into the housing on the track an electrical connector on the subassembly automatically connects with a circuit board positioned in the housing in perpendicular relation to the tracks.
