Abstract
A bulb-type semiconductor light-emitting device lamp having wide light distribution characteristics which are similar to those of a typical incandescent bulb is provided. The semiconductor light-emitting device lamp includes: a plurality of light-emitting devices that are arranged such that light is emitted therefrom toward a central axis of the bulb-type semiconductor light-emitting device lamp. Also, the bulb-type semiconductor light-emitting device lamp includes a heat dissipation structure having a plurality of installation surfaces that surround the central axis and are separated from each other, wherein each of the plurality of light-emitting devices includes one or more light-emitting devices.
