Abstract:
1. A method of providing control signals for a luminaire which can radiate light in different colours, having the following steps: a1) input of input quantities into an input unit of a control device, comprising a computation unit for determining a series of at least three colour locations, which identify three different colours, depending on the input quantities, the colour locations being chosen so that in a co-ordinate system which represents the latter, they are at least approximately on a specified colour change curve, and that between any two colours which are adjacent according to the colour change curve, at least approximately equally great colour distances are present, and for determining, for the luminaire, control signals using which the luminaire can be caused to radiate light in the at least three colours, and a transmission unit for transmitting the control signals to the luminaire, wherein the input quantities are two colour locations which differ from each other, and wherein the first colour location identifies a first colour and the second colour location identifies a second colour which differs from the first colour, a2) depending on the first colour location and the second colour location—subject to the two conditions i) and ii) below—a colour location which is to be determined, and which identifies a further colour, is determined: i) the colour location to be determined, in the co-ordinate system, together with the first and the second colour location, is at least approximately on a specified colour change curve, and ii) the colour distance between the first and the second colour, or an integer multiple of this colour distance, at least approximately equals the colour distance between the first and the further colour or between the second and the further colour, and b) on the basis of the determined colour location, a control signal which causes the luminaire to radiate light in the further colour corresponding to the determined colour location is generated.
