RARE EARTH OPTICAL ELEMENTS FOR LED LAMP

摘要

The present disclosure relates to optical elements and coatings comprising rare-earth element (REE) compounds for light wavelength attenuation of light emitting diode (LED) elements and lamps. More particularly, the present disclosure relates to LED elements and lamps comprising wavelength attenuating elements comprising REE compounds having at least a portion of non-crystalline, non-hydrate form, methods of preparing such elements, and LED elements, LED arrays, LED packages, optical elements, lamps and systems made with same.

主权项

1. A composition comprising a polymer matrix comprising at least one rare-earth element (REE) compound, at least an amount of the REE compound present in an amorphous or non-crystalline form, or present substantially without hydrate forms.
