Abstract (en)
The projection lamp includes a set of at least three different lamps (5A, 5B, 5C) supplied by three separate circuits (4A, 4B, 4C). These are controlled from a common control desk (2) by three switches (2A, 2B, 2C). The lamps may be dichroic lamps of different colours, or may be white lamps with different coloured filters attached. Each switch may be controlled over a range of 0-100%, so that any chosen combination of colour may be achieved. <IMAGE>
