    摘要： The invention provides an illumination device comprising a light source and a transmissive arrangement. The light source is arranged to generate light source light and comprises a light emitting device (LED), arranged to generate LED light and a carrier comprising a first luminescent material. The carrier is in contact with the LED and the first luminescent material is arranged to convert at least part of the LED light into first luminescent material light. The transmissive arrangement of a second luminescent material is arranged remote from the light source and is arranged to convert at least part of the LED light or at least part of the first luminescent material light and/or at least part of the LED light. The invention overcomes current limitations of remote luminescent material systems in spot lighting. In addition, an extremely simple way of realizing light sources with various correlated color temperatures is allowed, based on just a single type of white (or whitish) light source in combination with various (red-orange) remote luminescent materials.

The first light-collimator is arranged around a longitudinal axis (25) of the illumination system, and second light-collimator is being arranged around the first light-collimator along the longitudinal axis. Light propagation in the first light-collimator on total internal reflection. Light propagation in the second light-collimator is based on total internal reflection or on reflection at an outer surface of the second light-collimator facing away from the longitudinal axis. The cavity (3) is provided between the first and the second light-collimator. The cavity is provided with a switchable element based on electrowetting, wherein the switchable optical element is switchable in a mode of operation reducing the effect of the second light-collimator.
