FIELD: electricity.SUBSTANCE: invention relates to lighting engineering. The lamp unit (100) with plurality of light sources (120a-e) is controlled by the control unit (110) designed to control a sequence of excitation settings (Sa-e) for the plurality of light sources based on switching signal (Sk) delivered to the lamp unit. The control unit is made so that it sets valid excitation settings in the preset way depending on time elapsed between the signal deactivation and repeated activation. Within limits of the first preset time interval the subsequent excitation setting is used for the light sources, upon the second preset time interval the previous excitation setting is used for the light sources, and within limits of the intermediate time interval between ending of the first preset time interval and ending of the second preset time interval the preset excitation setting is used.EFFECT: improved quality of colour settings for the lighting system.15 cl, 6 dwg |
