PURPOSE: An image projection apparatus is provided to express various images and texts on an object because an image filter is arranged in a front side through which the collimated light is emitted. CONSTITUTION: An image projection apparatus comprises a case(10), a board(20), a condensing lens(30), a collimated light lens(40), and an image filter(50). The board closes a first open side and a LED(Light Emitting Diode)(21) for emitting the light to a second side is mounted on the board. The condensing lens is fixed near a second side over a focal length. The collimated light lens generates lights emitted from the condensing lens as collimated lights and emits the collimated lights to the second side. The image filter passes through some of the collimated lights emitted from the collimated light lens. |
