  • colour settings or scenes comprising fixed luminous flux from red, green and blue, and neutral tone possibly yellow, light sources and cycling through the stored scenes.
  • This requires the entering and storing of a large number of scenes, a laborious and time consuming process.
  • these factors must be set for each scene created.
  • US 5,530,322 discloses a lighting control system to control multiple zones of lighting through multiple dimming circuit. However, there is no disclosure therein of maintaining an overall predetermined luminous flux or colour saturation as the luminous flux of differently coloured lights is varied.

Respective outputs from the slider controls are each connected to a multiphase oscillator 30 such that the multiphase oscillator may modulate the base values set by the sliding controls.
  • This is illustrated in Figure 1 as the output from the slider controls 21, 22, 23 being summed, by summing modules 41, 42, 43, with red, green and blue outputs 31, 32, 33 respectively from the multiphase oscillator 30, to give modulated outputs on lines 411, 421, 431 respectively.

  • a period setting input 35 is provided for setting the length of a period through which the multiphase oscillator 30 cycles.
  • further inputs are provided: a waveform selector 36 to select a shape of waveform of the modulation; a colourwash selector 37, possibly with associated signal lamps, to select one of a plurality of types of colourwash to be described below, generated by the multiphase oscillator, and a cycle direction selector 38 for selecting freezing of the colourwash cycles, or a direction in which the colourwash cycles through the colours, which may have associated indicator lamps to indicate a selected status.
  • the pastel control module 50 also has as an input a pastel, or colour saturation, level selector 51.
  • An output from the pastel, or colour saturation, control module 50 is input as a neutral light channel together with the red, green and blue outputs from the multiphase oscillator 30 to a blackout module to allow blacking out one or more of the light channels controlled by a blackout selector input 61, which may have an associated signal lamp such as a light emitting diode (LED) to indicate when blackout is operational.
  • a blackout selector input 61 which may have an associated signal lamp such as a light emitting diode (LED) to indicate when blackout is operational.
  • Output from the blackout module 60 is fed, preferably using a four-wire buss, directly to linear controlled light sources and in parallel to the inputs of a linear power conversion module 71 to apply a dimmer curve for, for example, incandescent and halogen lamps, to a cold cathode conversion module 72 to a apply a dimmer curve for cold cathode neon lamps and to a fluorescent conversion module 73 to apply a dimmer curve for fluorescent lamps.
  • the output to fluorescent lamps may be through a digital interface using Manchester encoding and the output to other lamps may use a known Digital Multiplexer (DMX) protocol for lamp dimming control.
  • DMX Digital Multiplexer
  • the apparatus may have two separate digital outputs, a first using a known RJ12 connection system to drive digital fluorescent display units and a second to provide DMX output simultaneously to drive DMX-controlled lighting systems such as incandescent lamps, light-emitting diodes or cold cathode lighting.
  • DMX-controlled dimming packs can be used to control incandescent loads fitted with RGBY dichroic or other filters and similar dimmers may be used to drive suitable neon transformers for the control of RGBY neon/argon lighting.
  • an analogue voltage protocol in combination with a digital/analogue converter, may be used.
  • Suitable fluorescent light sources may have fluorescent tubes sleeved in red, green, blue and neutral, possibly yellow filters to provide RGB mixing with variable warmth using the yellow source.
  • Data connection to the fluorescent unit may be by a known daisy-chained RJ12 plug and socket system.
  • the fluorescent conversion module 73 is also provided with a minimum fluorescent level selector 731 for use in a manner to be described.
  • base levels of red, green and blue light channel levels are selected using the respective colour selectors 21, 22, 23 to produce a required basic hue to be modulated.
  • the pastel control selector 51 is set to produce a required colour saturation to generate desired warmth of colour.
  • the depth or amplitude control 34 is set to determine a required percentage or depth of modulation to be imposed on the base levels of red, green and blue by the multiphase oscillator 30. The depth of change can be set in the range 0% - 100%, to give either subtle changes of hue or dramatic colour changes.
  • the waveform selector is set to determine a shape of modulation wave, e.g. sine, ramp or peak wave, to be imposed by the multiphase oscillator 30 on the base values of the red, green and blue values selected.
  • the waveform selector may be designed to act individually on each of the light channels, so that different waveforms may be selected for each light channel, or may be designed simply to select the same waveform for all channels, which is normally sufficient.
  • the period of the selected waveform for example between 10 seconds and 24 hours per complete cycle, is selected using the period setting selector 35.
  • a desired colourwash type that is the relative phasing of the RGB or, using an additional yellow light channel, RGBY waveforms, for example an RGB colour cycle, in which a three-phase waveform is fed to the three colour outputs, or a RGBY colour chase cycle, using a four-phase waveform sequence, is selected using the colourwash type selector 37 and the order of the cycle selected using the cycle direction selector 38.
  • the depth or amplitude of modulation and the period of the cycle of the waveform can be selected differently for each light channel, but in practice it is found sufficient to select the same depth and period for each light channel. Setting the period the same for each light channel results in a repeatable colour cycle, this is usually considered desirable.
  • the absolute depth of modulation is likely to be different for each colour channel as the modulated signal is a product of the percentage depth of modulation and the base level set for that colour.
  • the operation of the multiphase oscillator 30 is best understood by reference to Figure 3.
  • the multiphase oscillator 30 includes a clock generator 301 for generating a clock signal, the period of which may be varied by the period setting selector 35.
  • the clock signal output from the clock generator 301 is input to a counter 302, which is controlled by input from the cycle direction selector 38 to select whether the counter cycles forwards or in reverse or cycling is frozen.
  • Multiple outputs from the counter are input to waveform lookup tables 303 for generating waveforms through which the light channels are to be cycled with the period set by the period selector 35.
  • the type of waveform selected from the waveform lookup tables is determined by a setting of the waveform selector 36 which has three line bus input to the waveform lookup tables corresponding to the three light channels, indicating the type of waveform selected and relative phases of the three light channels.
  • the three phases of a three-phase output from the waveform lookup tables 303 are output on separate lines corresponding to the three separate light channels to respective modulation depth multipliers or amplitude modulators 341, 342, 343, controlled in parallel by the depth or amplitude control 34 to set the amplitude of the selected waveform to be used to modulate the base levels of the light channels set by the respective colour selectors 21, 22, 23, as described above.
  • respective outputs from the depth multipliers or amplitude modulators 341, 342, 343 are input to respective base colour multipliers or amplitude modulators 211, 221, 231 which also receive respective inputs from the base colour selectors 21, 22, 23.
  • Respective outputs from the colour multipliers or amplitude modulators 211, 221, 231 are then summed by the respective summing modules 41, 42, 43 with the base colour signals from the base colour selectors 21, 22, 23 to form respective modulated phased colour channels on respective output lines 411, 421, 431, as described above.
  • Figure 4 is a representation of colour space, in which directions of vectors represent colour or hue and the length of vectors represent colour saturation, i.e. the proportion of colour to white light
  • the length of the vectors is weighted according to the relative strengths of the RGB sources and by a factor to account for varying sensitivity of the human eye to different colours.
  • the figure shows vector addition of a red light component R, a green component G and a blue component B, with a light green resultant.
  • Modulated signals on lines 411, 421, 431 for the red, green and blue output from the multiphase oscillator 30 are input to the pastel, or colour saturation, control module 50 and a value of the neutral colour channel is selected such that a sum of the magnitude of a vector sum of the red, green and blue levels and the scalar neutral level remains constant, as determined by the value selected by the pastel or colour saturation level selector 51.
  • a pastel control may be used with any known RGB colour mixing system automatically to vary the intensity of a fourth neutrally coloured light source (preferably white or yellow) to provide a range of precisely controlled pastel shades, that is, colour saturations.
  • an illumination control module 80 controlled by an illumination setting input 81, may be provided to maintain an overall constant illumination level from the light sources controlled by the apparatus as the colourwash passes through a cycle.
  • a value of the neutral colour channel is varied such that a scalar sum of the red, green, blue and neutral level remains constant, at a value selected by the illumination setting input 81.
  • a constant illumination level control may be used with any known RGB colour mixing system automatically to vary the intensity of a neutrally coloured light source (preferably white or yellow) to provide a range of precisely controlled illumination level.
  • a master illumination level control may be provided (not shown) to scale all outputs in the range 0-100% of the value entering a four-wire buss to the blackout module 60.
  • the multiphase oscillator is used to perturb the base RGB levels to produce a controlled trajectory through the colour space shown in Figure 4.
  • Software in the pastel control module or the illumination control module respectively uses a fourth neutral light source to provide automated control of either the colour saturation or illumination, so that one of these characteristics is controlled during colour cycling.
  • the resultant instantaneous level of the neutral light channel is input with the red, green and blue modulated outputs from the multiphase oscillator to the blackout module 60 which may be used to extinguish all the light outputs by reducing the control outputs to zero, if desired.
  • Output from the blackout module 60 is fed directly to DMX-enabled lamps for varying the luminous flux from blue, green, red and neutral coloured lamps.
  • the output is also fed in parallel to the inputs of a linear power conversion module 71 to apply a dimmer curve for linear power conversion, to a cold cathode conversion module 72 to a apply a dimmer curve for cold cathode lamps and to a fluorescent conversion module 73 to apply a dimmer curve for fluorescent lamps.
  • the output to fluorescent lamps may be through a digital interface using Manchester encoding and the output to other lamps may use a known Digital Multiplexer (DMX) protocol for lamp dimming control. In this manner DMX-enabled lamps and non-DMX enabled lamps may be simultaneously controlled by the same controller.
  • DMX Digital Multiplexer
  • Controllers for fluorescent light fittings conventionally have a 'cut-off' light level below which the fluorescent tube is extinguished to extend tube life. While this feature may be included with the present invention, in order to prevent fluorescent lamps controlled by the lighting control apparatus from switching off at low luminous intensity, a minimum luminous flux may be set for the fluorescent lamps by the minimum fluorescent level selector 731 connected to the fluorescent conversion module 73. Although a slightly reduced chromacity range results from this adaptation, near low-light level operation is much smoother as the tubes are not switched off and on in normal operation during a cycle of the colourwash.
  • the invention therefore provides a digital colourwash lighting system for the synchronised colourwashing of fluorescent, cold cathode neon and other dimmable light sources.
  • This synchronised control is achieved by direct digital control of fluorescent light sources and the use of DMX protocol to control of other DMX-enabled dimmable light sources.
