摘要

A light distribution board having an improved light grating structure including a plurality of light refractive structures (1203,1204,1205,1206,1207) each with multiple focuses (1209,1211), 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 refractive structures each having multiple focuses, each light refractive structures having multiple focuses is composed of two or more arciform (concave or convex) lenses (1208,1210) and at least one lens with a non-arciform surface (1212) to form a light refractive structures having at least two 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 avoid the phenomenon of dazzling of eyes during looking at the light emitting member in the lamp, and the light beams become more tender under the condition that lose of brightness is minimum.
