ILLUMINATION DEVICE WITH REMOTE LUMINESCENT MATERIAL

摘要

The invention provides an illumination device comprising a light source (100) and a transmissive arrangement (200). The light source is arranged to generate light source light and comprises a light emitting device (LED) (110), arranged to generate LED light and a carrier (120) comprising a first luminescent material (130). The carrier is in contact with the LED and the first luminescent material (130) 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 colour temperatures is allowed, based on just a single type of white (or whitish) light source in combination with various (red-orange) remote luminescent materials.
