An embodiment includes a light emitting module which includes a tube-shaped transparent cover, a substrate arranged on one region of the inner surface, and light emitting devices arranged on the substrate, and a first reflection surface and a second reflection surface which are extended in the longitudinal direction of the cover to reflect light emitted from the light emitting module, and an edge which is located between the first reflection surface and the second reflection surface. One end of the first reflection surface and one end of the second reflection surface include a reflection part connected to the inner surface of the cover. The one end of the first reflection surface is located on one side of a vertical center line. The one end of the second reflection surface is located on the other side of the vertical center line. The vertical center line passes through the center of the cover and is a straight line vertical to the upper surface of the substrate. Based on the upper surface of the substrate, the height of the edge is lower than each end of the first reflection surface and the second reflection surface. |
