| 20120007130 | ILLUMINATION DEVICE WITH REMOTE LUMINESCENT MATERIAL - 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 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. | 01-12-2012 |

| 20100109575 | SINGLE CHIP LED AS COMPACT COLOR VARIABLE LIGHT SOURCE - The present invention relates to a color variable light-emitting device comprising an array of a plurality of LEDs formed on one highly resistive substrate, which array comprises a first, a second and a third set of at least one LED arranged to provide light of a first, a second and a third color, respectively. At least one of the sets is independently addressable. Further, each light-emitting diode in the array has a separate connection to a circuitry, and at least one of the sets comprises at least two LEDs, interconnected in series via the circuitry. Thus, all connections between separate LEDs, for example in the same set, can be done via the circuitry. This also allows for a very dense packing of the LEDs in the array, as no interconnects between different LEDs of the array need to be arranged in the array. | 05-06-2010 |
