Abstract:
A method for producing a color lighting display with gas discharge tubes, the method comprising: providing at least two gas discharge tubes in close proximity to each other, each tube generating a different color; providing a number of variable power sources equal to the number of gas discharge tubes; connecting one variable power source to each gas discharge tube, each tube having its own variable power source; and controlling each variable power source by pulsing at least one of the at least two gas discharge tubes at a frequency of greater than 30 Hz, pulsing a second one of the at least two gas discharge tubes at a second frequency of greater than 30 Hz, the pulsing of each gas discharge tube is out of phase with the other by at least 90.degree. in order to produce the appearance of a wide range of different colors when the at least two gas discharge tubes are viewed from a sufficient distance so as to appear as one light source.
