摘要: A light emitting module is configured to provide substantially uniform lighting using a plurality of lighting sources. The light emitting module includes a diffusion plate disposed at a set distance from the light emitting module. A light source substrate has a substantially quadrilateral outer perimeter with at least one gap formed therein, and a plurality of light sources are disposed on the light source substrate according to a repeated quadrilateral pattern. A distance between adjacent light sources in the repeated quadrilateral pattern is selected based on the set distance h from the diffusion plate to the light emitting module, and on a greater of two diagonal distances x, y of the quadrilateral pattern. The diffusion plate diffuses light emitted by the light sources to provide substantially uniform light. Various other aspects of the light emitting module are additionally described.
