<p>A controlling apparatus 3 for a lighting apparatus 4 having at least two light sources 5, 7, 9, 11, each generating light of a different colour, includes means 17 for storing calibration data relating to measured wavelengths and maximum intensities of light generated by each source, a processor 13 to drive the sources and a user-operable control 19 comprising respective variable controls nominally associated with each of the sources to enable a user to vary the intensity of each source to obtain a desired output colour and intensity. A further user-operable control 21 enables a user to specify and store a primary colour for each variable control. When a colour is specified for a variable control which differs from the measured wavelength of the light source nominally associated with that control, the processor will drive the light sources in response to operation of the control to generate the specified colour, enabling the lighting apparatus to emulate a different lighting apparatus having light sources with different characteristics.</p> |
