Abstract: An optical system comprising a light source comprising a plurality of light emitting elements (LEEs) is presented. The light source is mounted on the same substrate or chip board so that the LEEs are in thermal contact with each other such as to enable thermic conduction and heat transfer between the LEEs. The system is switchable between light source modes in which different light emitting elements or a different number of light emitting elements is switched in an on mode and in a down mode respectively. In all light source modes, one or more light emitting elements, such as those with longer expected lifetime, remain in the on mode, while one or more light emitting elements, such as those with shorter expected lifetime, may be switched in the down mode.
