In Ciungu (2021), the relationship between some algebraic structures and L-algebras has been researched. In this paper, according to the theory of ideals in algebraic structures, such as BCK-algebras, we study ideals in L-algebras. We present definitions of positive implicative (implicative, associative, ultra, involution) ideals of L-algebras, and examine the relationship between them. Specially, we present conditions where they coincide.
