An embodiment includes: a light emitting module which includes a tube-type transparent cover, a protruding support part arranged on the inner surface of the cover, a substrate arranged on the protruding support part, and light emitting devices arranged on the substrate; and a reflection part which includes first and second reflection surfaces extended in the lengthwise direction of the cover and an edge located between the first and second reflection surfaces, and has one end of the first reflection surface and one end of the second reflection surface which are connected to the inner surface of the cover. One end of the first reflection surface is located on one side of a vertical center surface. One end of the second reflection surface is located on the other side of the vertical center surface. The vertical center surface passes through the center of the cover, and is vertical to the upper surface of the substrate. The height of the edge is lower than that of each end of the first and second reflection surfaces. |
