Abstract
The lamp with easily changeable lighting colour controlled electronically, is capable for part of a second to change the colour in which it is lighting, and is adapted for lighting in open-air objects and equipment, in theatre stages, advertising billboards, in photo- and film-shooting sites, for light signalling, etc., in case when there are no objects moving in rotative and reciprocating motion due to a well-known stroboscopic effect. The principle of adjustable overlaying and subjective reception of phase-shifted wide-pulse adjusted light pulse with three constant colours is used, produced from individual pulse gas-discharge lamps (1, 2 and 3) with colouring mixtures of metallic vapours, such as Na, K, Rb, Cs and others, or non-metallic, such as In, B, and others, combined in a common glass body with a supply unit and control (4). Unit (4) forms supply voltage, ignition and gate-pulsing which determine the lighting of the individual pulse lamps with the necessary intensity, according to the individual case, average intensity for producing the desired lighting colour. 1 claim, 2 figures
