In this note we introduce L-⊕-supplemented modules as a proper generalization of ⊕-supplemented modules. A module M is called L-⊕-supplemented if for every ø ∈ End R øM), there exists a direct summand L of M such that Imø + L = M and Imø « L. It is shown that if M is a L-⊕-supplemented module with D 3 condition, then every direct summand of M is L ⊕-supplemented. We prove that if M = M 1 ⊕ M 2 is L-⊕-supplemented such that M 1 and M 2 are relative projective, then M 1 and M 2 are L-⊕-supplemented. We study some rings whose modules are L-⊕-supplemented.

Palabras clave : Supplemented module; L-⊕-supplemented module; dual Rickart module; endomorphism ring; V-ring.
