Cree’sꢀ EZBright™ꢀ LEDsꢀ areꢀ theꢀ nextꢀ generationꢀ ofꢀ solid-stateꢀ LEDꢀ emittersꢀ thatꢀ combineꢀ highlyꢀ efficientꢀ InGaNꢀ
materialsꢀwithꢀCree’sꢀproprietaryꢀopticalꢀdesignꢀandꢀdeviceꢀtechnologyꢀtoꢀdeliverꢀsuperiorꢀvalueꢀforꢀhigh-intensityꢀLEDs.ꢀ
TheꢀopticalꢀdesignꢀmaximizesꢀlightꢀextractionꢀefficiencyꢀandꢀenablesꢀaꢀLambertianꢀradiationꢀpattern.ꢀAdditionally,ꢀtheseꢀ
LEDsꢀareꢀdieꢀattachableꢀwithꢀconductiveꢀepoxy,ꢀsolderꢀpasteꢀorꢀsolderꢀpreforms,ꢀasꢀwellꢀasꢀtheꢀfluxꢀeutecticꢀmethod.ꢀ
Theseꢀverticallyꢀstructured,ꢀlowꢀforwardꢀvoltageꢀLEDꢀchipsꢀareꢀapproximatelyꢀ170ꢀmicronsꢀinꢀheight.ꢀCree’sꢀEZ™ꢀchipsꢀ
