Claim:
1. A light emitting device, comprising: a substrate including an entire top surface that is flat; a light emitting diode on the substrate; a lead frame disposed on the flat top surface of the substrate, the lead frame electrically connected to the light emitting diode; a dam member disposed on the substrate and being adjacent to the light emitting diode, the dam member having a circular configuration which has an opening; a first member disposed on the light emitting diode, the first member including a fluorescent substance to convert a light emission spectrum of light from the light emitting diode; a second member disposed in the opening of the dam member, a circumference of the second member being defined by the dam member and contacting a side surface of the dam member; and a lens disposed on the second member, wherein a height from a lowermost portion of the bottom surface of the lens to an uppermost portion of a top surface of the lens is larger than a height from a lowermost portion of a bottom surface of the first member to an uppermost portion of a top surface of the first member or from a lowermost portion of a bottom surface of the second member to an uppermost portion of the top surface of the second member, wherein a largest width of the opening of the dam member and a largest width of the second member are the same, wherein the second member is disposed between an inner vertical side surface of the dam member and a side surface of light emitting diode, wherein the inner vertical side surface of the dam member contacts a side surface of the second member and is vertically extended to the flat top surface of the substrate, wherein the second member and the lens are formed of different materials. wherein the first member is disposed between the light emitting diode and the second member.
