An optical semiconductor-based tube type lighting apparatus capable of enlarging light distribution to have improved assembly characteristics. The lighting apparatus includes an elongated light-transmitting tube, and a plurality of optical semiconductor modules arranged along a circumference of the light-transmitting tube and separated from each other in a cross-sectional view of the light-transmitting tube. Each of the optical semiconductor modules is placed on a point, which is not on a central axis line of light emitted from other optical semiconductor modules, so as not to face another optical semiconductor module at an opposite side thereof.
