Claim:
1. An illumination apparatus comprising: a tube shaped cover; a 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 provided on the substrate; a reflector extending in a longitudinal direction of the cover and having a first reflective surface, a second reflective surface, and an edge positioned between the first reflective surface and the second reflective surface, the first and second reflective surfaces reflecting light emitted by the light emitting module; and a drive unit positioned between the reflector and the inner circumferential surface of the cover and configured to drive the light emitting module, wherein one end of the first reflective surface and one end of the second reflective surface are connected to an inner circumferential surface of the cover, wherein the edge is positioned between a horizontal centerline and the plurality of light emitting devices and spaced away from the inner circumferential surface of the cover, wherein the horizontal centerline is a straight line passing a center of the cover and is parallel with an upper surface of the substrate, wherein the edge vertically overlaps the plurality of light emitting devices along a vertical centerline, which passes through the center of the cover and is perpendicular to the upper surface of the substrate, wherein the horizontal centerline passes through the center of the cover that is equidistant along the vertical centerline from the inner circumferential surface of the cover, wherein the drive unit is provided on and contacts with a first surface of the reflector and a second surface of the reflector, the first surface being at an opposite side from the first reflective surface and the second surface being at an opposite side from the second reflective surface, wherein the first and second reflective surfaces are provided between the light emitting module and the drive unit, and wherein one end of the first surface and one end of the second surface are connected to the inner circumferential surface of the cover.
