citazione

The light source is of paramount concern in all projection systems. In my 'Chromara, 1966', I used 12-V automobile headlight lamps. Sources are available having small size, high intensity, adequate lifetime and good color balance, in particular, the tungsten-halogen incandescent lamp and the Xenon compact arcs are preferred sources, although they become very hot in operation. Incandescent projection lamps with internal reflectors are available and special designs alleviate cooling problems considerably. At low power (36 W), there is a novel design filament lamp from Japan that has a square filament only 5 mm on a side, mounted so that the lamp may be used end-on to simplify cooling.
