The dots are concavem icrolensw ith diam eters of 40 m and heights of 10 m, the dots zone of LGP is d ivided into several bar blocks and the param eters of each block are deduced. To verify the h igh un iform ity w ith the dots pattern ach ieved a bove, the m odel of LGP is set up. The area of the LGP is 70. 0 mm 41. 5 mm, w ith m icrolens on the bottom and ligh ted by LED. Analys is resu lt w ith raytracingm ethod shows the uniform ity is 0% . The m ethod proposed in th is paper can be applied to the des ign of LGP w ith h igh uniform ity LED illum inating.
