Abstract:
1. An illumination apparatus comprising: a baseboard having a front surface; a plurality of semiconductor light-emitting devices each having an individual translucent substrate separate from the substrate of others of the light-emitting devices and a semiconductor light-emitting layer disposed on the substrate; a reflective layer disposed on and contiguous with the front surface of the baseboard, the reflective layer having a flat light reflective surface on which the semiconductor light-emitting devices are disposed in intervals; a plurality of conductor parts provided on the flat light reflective surface of the reflective layer in intervals, the conductor parts being adjacent to the semiconductor light-emitting devices and electrically connected to the semiconductor light-emitting devices through bonding wires, wherein a thickness of the substrates of the semiconductor light-emitting devices is larger than a thickness of the conductor parts so that the light-emitting layers are disposed further from the reflective layer than the conductor parts; and a translucent adhesive layer that bonds the substrate of each of the semiconductor light-emitting devices onto the flat light reflective surface of the reflective layer, thereby securing the semiconductor light-emitting devices on the reflective layer.
