The research on the relation between all kinds of Li ideals in lattice implication algebras has proved that A×B is an Li-ideal of L1×L2,if A,B are the Li-ideals of L1 and L2 respectively.The direct product of two Lukasiewicz chain-type lattice implication algebra Lm and Ln has only two prime Li-ideals {a1}×Lm and Ln×{b1}.
