Abstract
The present invention relates to a projection apparatus, comprising a main part and a plurality of lens units. Each lens unit is in a shape capable of directing light by a specific angle so that the light beam pointing to the main part can be focused and redirected to the projection screen; thus, the light points of the plurality of lens units can be focused to form a lighter image; alternatively, the light points of said plurality of lens units can be focused to form a lighter background so as to display a darker darkened image on a lighter background or to project a magnified image of the image unit corresponding to the lens units. Therefore, the present invention provides a projection apparatus with simplified structure which can be manufactured easily with lower cost.
