A lighting apparatus includes a semiconductor light source in direct contact with a polymer composite comprising a color stable Mndoped phosphor, wherein the lighting apparatus has a color shift of &#x2264;1.5 MacAdam ellipses after operating for at least 2,000 hour at a LED current density greater than 2 A/cm, a LED wall-plug efficiency greater than 40%, and a board temperature greater than 25&#xb0; C.

A circuit breaker having a monolithic structure and method of making is disclosed. The monolithic structure includes an arm portion having copper and a contact portion having a composite material. The composite material has a metallic matrix and a second phase disposed in the metallic matrix. The method of making the monolithic structure includes introducing a first powder into a first region of a mold, introducing a second powder into a second region of the mold, and consolidating the first powder and the second powder together. The first region of the mold corresponds to a contact portion, and the second region corresponds to an arm portion of the monolithic structure of the circuit breaker.

Monolithic contact system and method of forming

A process for synthesizing a color stable Mndoped phosphor includes contacting a precursor of formula I, in gaseous form at an elevated temperature with a fluorine-containing oxidizing agent to form the color stable Mndoped phosphorA[MF]:Mn&#x2003;&#x2003;Iwherein

A color stable Mn4+ doped phosphor of formula I,A[MF]:Mn&#x2003;&#x2003;I

A luminescent material includes an aluminate phosphor of formula IAMgAlO:Eu, R, where&#x2266;0.4, 0&#x2266;&#x2266;1 and 0&#x2266;&#x2266;0.2. A is selected from Ca, Ba, and Sr and combinations thereof. The aluminate phosphor is doped with a rare earth ion (R), which exists in stable multi-valence states in the luminescent material. Ris selected from the group consisting of Sm, Yb, Tm, Ce, Tb, Prand combinations thereof. Phosphors of formula I may be blended with other blue, yellow, orange, green, and red phosphors to yield white light phosphor blends. A lighting apparatus including such a luminescent material is also presented. The light apparatus includes a light source in addition to the luminescent material.
