An illumination apparatus includes a tube type light-transmissive cover, and light emitting module having a substrate provided in one region of an inner circumferential surface of the cover and a plurality of light emitting devices disposed on the substrate. A reflector extends in a longitudinal direction of the cover and includes a first reflective surface, a second reflective surface, and an edge positioned between the first reflective surface and the second reflective surface. One end of the first reflective surface and one end of the second reflective surface are connected to the inner circumferential surface of the cover.
