LED photoluminescence granulation

LED photoluminescence granulation

Freeze Granulation is today used for commercial production of homogeneous granules for the production of oxides used as a ceramic phosphor plate for white illumination in LED Lighting. By using Freeze Granulation of the powder and binder mixture, compared with spray drying, it is possible to manufacture a homogeneous phosphor plate with optimal properties for to generate a soft and warm white light from high power LEDs.

Homogeneous LED phosphor materials

Freeze Granulation offers a unique technology for to make homogeneous LED phosphor materials resulting in improved photoluminescence properties and thus, Freeze Granulation will give you high power LEDs with superior final properties. Most LEDs that are emitting a soft white light have been covered by a yellowish phosphor coating or plate usually made of cerium doped yttrium aluminium garnet (YAG:Ce) crystals, which have been processed using powder processing techniques and bound into a ceramic plate, glass or with a resin.
