    • 专利摘要:
    Device for projecting a board that is characterized in that it comprises a point light source (6), a support or base (4) on which the light emitter is placed and at least one opaque surface that blocks said light except for one plurality of holes (2) that the (s) cross from part to part. Where the holes have a shape such that the light beams projecting through them spatially form the cells of a game board (7) on the flat surface on which the device is supported when the light source is active. Thus, the present invention proposes a solution for projecting the surface of the board (7) on a flat surface in low lighting conditions, so that the limits of each cell are perfectly visible to the players even though there is no board physical as such.
