Abstract:
1. A light emitting module, comprising: a plurality of light emitting diodes; and a module substrate including a wiring portion disposed with the plurality of light emitting diodes and electrically connected to the plurality of light emitting diodes, and a heat radiation portion folded from the wiring portion and disposed under the plurality of light emitting diodes, wherein the plurality of light emitting diodes includes a first light emitting diode disposed on a first outer region of the wiring portion, a second light emitting diode disposed on a second outer region of the wiring portion, and a third light emitting diode disposed on a center of the wiring portion, wherein a width between the center of the wiring portion and an end of the heat radiation portion is wider than a distance between the first outer region of the wiring portion and the end of the heat radiation portion, in the heat radiation portion of the module substrate, wherein the wiring portion of the module substrate includes a metal layer, a wiring layer on the metal layer, and an insulating layer between the metal layer and the wiring layer, wherein the heat radiation portion is extended from the metal layer, and the heat radiation portion is spaced apart from the insulating layer and the wiring layer, and wherein the wiring layer is electrically connected to the plurality of the light emitting diodes, wherein the metal layer of the wiring portion is bent from the heat radiation portion in a substantially vertical direction, wherein the metal layer of the wiring portion has a same thickness as the heat radiation portion, wherein an entire region of the heat radiation portion is formed of the same metal layer as the metal layer of the wiring portion, and wherein the heat radiation portion has a width wider than a width of the metal layer of the wiring portion.
