The invention discloses a light-emitting diode device which includes a substrate with a circuit pattern, a reflective layer arranged on the substrate, at least one light-emitting chip arranged on the reflective layer, a reflector winding the light-emitting chip, a colloid covered on the light-emitting chip, and a phosphor powder layer arranged above the colloid. The light-emitting chip has a conductive part, and the circuit pattern of the substrate is connected with the conductive part. In the embodiment, a plurality of light-emitting chips are arranged in a linear way, moreover, a distance piece is arranged between two adjacent light-emitting chips.
