Illumination device with LED with a self-supporting grid containing luminescent material and method of making the self-supporting grid

The invention provides an illumination device (10) comprising (a) a light emitting diode (LED), (b) a heat sink (85) and (c) a self-supporting grid (500). This grid (500) is arranged downstream of the LED (20) and arranged so as to be in contact with the heat sink 85. The self-supporting grid (500)...

Beschreibung
Zusammenfassung:	The invention provides an illumination device (10) comprising (a) a light emitting diode (LED), (b) a heat sink (85) and (c) a self-supporting grid (500). This grid (500) is arranged downstream of the LED (20) and arranged so as to be in contact with the heat sink 85. The self-supporting grid (500) comprises a plurality of grid structures (501) and a plurality of grid openings 502) between the grid structures (501). At least part of the total number of grid openings (502) encloses luminescent material (51), thereby providing luminescent material-filled grid openings (551). The luminescent material (51) is arranged to absorb at least part of the LED emission (21) and emit luminescent material emission (13). The LED (20) and the luminescent material (51) are arranged to provide light (115) of a predetermined color downstream of the self-supporting grid (500).
