Abstract

685,209. Control systems for lighting, WILLIAMS, R G. Aug. 16, 1950 [Aug. 16, 1949; Feb. 3, 1950], Nos. 21305/49 and 2875/50. Class 38 (iv). A colour control system, for obtaining lighting effects by combining in different proportions the light from differently coloured lamps W, R, G, B, comprises dimmers A, B, a three-bank rotary selector switch C and a rotary " colour-intensity " range switch D, the two dimmers and the selector switch being operated simultaneously, but at different rates, by a common control member. The arrangement is such that, with the range switch set in either the "deep colotir or " pastel positions, movement of the selector switch progressively through positions 1-9 successively connects a different one of lamps R, G, B to the supply 100, 101 over contacts 39, 56-60, whilst another lamp of different colour is connected to the supply through dimmer A over contacts 40, 42-49. As the switch C moves from one position to the next the lamp associated with contacts 42-49 is faded up or down and is then either transferred to one of' contacts 56- 60, in order to remain at full brilliance for a period, or is disconnected at contacts 42-49. In the " pastel position of switch D, the white lamp W supplements the others and is faded down by dimmer B whilst the switch C moves from position 1 to position and then faded up from position to position 9. In a modified arrangement the dimmers move at the same rate but are out-of-phase with one another. A switch mayalso be provided whereby either of two control ranges of the dimmer associated with the white lamp may be selected. The common control member may be motor-driven. Specification 646,642, [Group XI], is referred to.
