Abstract:
1. A light-emitting diode apparatus, comprising: a base including an upper surface, a lower surface opposite the upper surface and a peripheral edge side surface provided between the upper surface and the lower surface and having thermal conductivity; an insulative substrate including an upper surface provided with electrodes, a lower surface opposite the upper surface and a pass-through hole provided to pass through the upper surface and the lower surface, the lower surface of the insulative substrate being attached to the upper surface of the base, and the electrodes being along opposite sides of the pass-through hole; at least one base-mounting area that is exposed part of the upper surface of the base, exposed within the pass-through hole of the substrate; a plurality of light-emitting diode elements mounted on the base-mounting area and electrically connected to the electrodes which are provided along opposite sides of the pass-through hole; and a frame disposed to surround the base-mounting area and configured to form a light-emitting area.
