PURPOSE: An optical semiconductor based tube type lighting apparatus is provided to lighten a dark rear region by using optical semiconductor modules. CONSTITUTION: The optical semiconductor base tube type lighting apparatus(1) has a shape like a fluorescent lamp. The optical semiconductor base tube type lighting apparatus comprises a light-transmitting tube(20) having a circular cross section and three optical semiconductor modules(40a,40b,40c) arranged along the circumference of the light-transmitting tube. The light-transmitting tube includes three long slit pieces(20a,20b,20c). The slit piece is made of a plastic material against impact. Three long installation gaps are formed among the slit pieces. |
