An LED illuminating apparatus includes a substrate, an envelope facing to the substrate, and at least one LED arranged on the substrate. The substrate includes a first surface. The first surface includes an installed surface and a convex surface connected to the installed surface. The envelope includes a light emitting portion faces to the first surface of the substrate. The at least one LED is arranged on the installed surface of the substrate. A part of light emitted from the at least one LED is reflected by the convex surface of first surface of the substrate, and travels through the envelope to an outside. |
