Abstract：The dot radius distribution functions of light guide plate with edge lighting are derived in this paper for unilateral, bilateral and quadrilateral edge lighting.The function with unilateral lighting is derived based directly on the basic principle of light guide plate, while the functions with bilateral and quadrilateral edge lighting are the solutions of the modified Gaussian distribution function under the boundary value conditions of the plate.The functions, with the variables having definite physical meaning such as length of the light guide plate and the radius of the bordered and central dots, can be directly used for the design of rectangle light guide plate with different size.In order to further optimize the luminance uniformity of the light guide plate, a kind of very simple optimizing method called "local area randomization method" are proposed.The simulation results for three types of edge lighting and the measure results of actual manufacture lamps for bilateral edge lighting as an example have very good luminance uniformity.It is shown that the above method is a successful design method for light guide plate.
