Zusammenfassung:Light-emitting diode (LED) packages, and more particularly arrangements of light-altering coatings in LED packages are disclosed. Exemplary LED packages may include lead frame structures that are at least partially encased by a housing. Arrangements of light-altering coatings may be provided that cover one or more portions of lead frame structures exposed within LED package recesses. By providing light-altering coatings that cover lead frame structures within package recesses, negative impacts from potential lead frame discoloration due to environmental exposure may be reduced. Additionally, such light-altering coatings may be configured to reflect light emissions from LED chips before reaching portions of lead frame structures. Light-altering coating arrangements are disclosed where light-altering coatings are arranged in contact with LED chips or, alternatively, in a spaced relationship with LED chips. Retention structures are disclosed that may define boundaries of light-altering coatings along recess floo
