The spacing between the transparent ink sticks 211 is optimally 1mm-3mm, and the radian of the transparent ink sticks 211 is not more than 75 degrees, so that the photoresistance can be reduced. The distance between the two end areas of the transparent ink sticks 211 is smaller than the distance between the middle areas of the transparent ink sticks 211, so that the external projection light rays can be more uniform. Specifically, the spacing between the two end regions of the plurality of transparent ink sticks 211 is 0.5mm to 1.5mm.
