Abstract:
1. A light emitting device module, comprising: a heat transfer member that defines a cavity; a first conductive layer and a second conductive layer contacting the heat transfer member via an insulating layer, the first conductive layer and the second conductive layer being electrically separated from each other in accordance with exposure of the insulating layer or exposure of the heat transfer member; and at least one light emitting diode electrically connected to the first conductive layer and the second conductive layer, wherein the at least one light emitting diode thermally contacts an exposed portion of the heat transfer member and the insulating layer has an exposed portion disposed outside of the cavity, and wherein the first conductive layer has a first open region formed outside the cavity, and the first open region being formed above the heat transfer member, and the second conductive layer has a second open region formed outside the cavity, and the second open region is formed above the heat transfer member, wherein a peripheral shape of the insulating layer exposed through the first conductive layer is the same as the peripheral shape of the first open region formed in the first conductive layer, and a peripheral shape of the insulating layer exposed through the second conductive layer is the same as the peripheral shape of the second open region formed in the second conductive layer, and wherein the first open region includes at least one pattern that divides the corresponding first conductive layer into conductive layer portions at opposite sides of the first open region, and the divided conductive layer portions being electrically connected by at least one connector provided on the at least one pattern.
