A light-emitting diode device includes: a substrate; an upper metal film disposed on an upper surface of the substrate, and including a chip-mounting region and a plurality of conductive pad regions; two first light-emitting chips and two second light-emitting chips disposed on the chip-mounting region, the first and second light-emitting chips being disposed alternately, two of the first and second light-emitting chips being opposite to each other; a fluorescent layer coated on the first light-emitting chips; and a lens disposed on the substrate to cover the first and second light-emitting chips and the fluorescent layer.
