Abstract: A method is disclosed for forming a blended phosphor composition. The method includes the steps of firing precursor compositions that include europium and nitrides of at least calcium, strontium and aluminum, in a refractory metal crucible and in the presence of a gas that precludes the formation of nitride compositions between the nitride starting materials and the refractory metal that forms the crucible. The resulting compositions can include phosphors that convert frequencies in the blue portion of the visible spectrum into frequencies in the red portion of the visible spectrum.

Abstract: The present disclosure is directed to LED components, and systems using such components, having a light emission profile that may be controlled independently of the lens shape by varying the position and/or orientation of LED chips with respect to one or both of an overlying lens and the surface of the component. For example, the optical centers of the LED emitting surface and the lens, which are normally aligned, may be offset from each other to generate a controlled and predictable emission profile. The LED chips may be positioned to provide a peak emission shifted from a perpendicular centerline of the lens base. The use of offset emitters allows for LED components with shifted or tilted emission patterns, without causing output at high angles of the components. This is beneficial as it allows a lighting system to have tilted emission from the LED component and primary optics.
