A thin multi-layer LED array engine is provided, which includes a substrate having a phosphor layer and a silica gel protection layer formed thereon. The phosphor layer is disposed on LED dices and makes direct contact with the substrate, and the silica gel protection layer is disposed on the phosphor layer. The LED dices are covered with the phosphor layer, and thereby the phosphor particles in the phosphor layer can be uniformly dispersed around the LED dices, so that the narrow color temperature distribution can be achieved. Furthermore, the phosphor layer makes direct contacts with the substrate, and thereby heat generated in the phosphor layer can be effectively dissipated through the substrate, and thereby the reliability of the optical components can be increased.
