Summary:PURPOSE: A light tunnel and a projection apparatus with the same are provided to reinforce the coupling structure of parts of a light tunnel by employing two side mirrors with inclined reflection surfaces between top and bottom mirrors. CONSTITUTION: A light tunnel(100) comprises top and bottom mirrors(110,120), two side mirrors(130,140) and a total reflective surface. The top and bottom mirrors are installed to face each other. The two side mirrors are connected to the top and the bottom mirror. The total reflective surface is formed of the reflecting surface of each mirror. The two side mirrors are arranged with the inner side inclined and the outer side perpendicular to the top and the bottom mirror.
