Abstract:
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 formed on the flat top surface of the substrate, the lead frame electrically connected to the light emitting diode; a dam part formed on the substrate and being adjacent to the light emitting diode; a first member formed 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 being surrounded by the dam part and formed on the substrate adjacent to the first member; and a lens covering the first member, the second member and the light emitting diode, wherein a distance from an uppermost surface of the dam part to a top surface of the substrate is less than a distance from an uppermost surface of the first member to the top surface of the substrate, the dam part is in a circle shape and has an opening, at least a portion of the dam part has a vertical inner surface that contacts the second member, a width of the substrate is greater than a width of the dam part so that the substrate extends beyond the dam part, the lead frame includes a portion that is disposed on the substrate and extending beyond the darn part, and an outer side of the lens does not extend beyond the dam part.
