Abstract:
1. An integrated apparatus including: an electrically insulative and thermally conductive substrate formed with a first side and an opposite second side and comprising a circuit layout layer provided on the first side of the electrically insulative and thermally conductive substrate, the circuit layout layer comprising through-silicon-vias; a plurality of driver chips provided on the first side of the electrically insulative and thermally conductive substrate; a power supply provided on the first side of the electrically insulative and thermally conductive substrate and electrically connected to the driver chips; a heat radiation unit provided on the first side of the electrically insulative and thermally conductive substrate so as to overlie the circuit layout layer and such that the circuit layout layer is interposed between the heat radiation unit and the electrically insulative and thermally conductive substrate; and a plurality of LED chips provided on the opposite second side of the electrically insulative and thermally conductive substrate opposite the heat radiation unit and electrically connected to the driver chips via the circuit layout layer.
