A light distribution board having a plurality of light gratings each with multiple focuses, the light distribution board is used on a light outputting surface of a lamp, in which at least a transparent board is provided on at least one of its surfaces with a plurality of light gratings each having multiple focuses, each light grating having multiple focuses is composed of two or more mutually integratedly juxtaposed arciform (concave or convex) lenses to form a convex lens grating having two or more focuses. With this structure, light beams can be uniformly distributed and can avoid the phenomenon of Gauss distribution that makes the area below the lamp especially bright, and can avoid the phenomenon of dazzling of eyes during looking at the light emitting member in the lamp; and except the light beams directly under the lamp, other light beams around the lamp are completely obscured, thus an effect of no optical pollution can be obtained.
