  • Patent number: 8791471
    Abstract: A multi-chip lighting module is disclosed for maximizing luminous flux output and thermal management. In one embodiment, a multi-chip module device comprises a substantially thermally dissipative substrate with a dark insulating layer deposited on a surface of the substrate. A plurality of light emitting devices is also provided. An electrically conductive layer is applied to a surface of the substrate, with the conductive layer comprising a plurality of chip carrier parts each having a surface for carrying at least one of the light emitting devices. Each light emitting device has a first and a second electrical terminal. A reflective layer is also provided that at least partially covers the conductive layer.
