LED大型圆形阵列的光斑照度均匀性
Uniformity of Light Spot Illumination of Large LED Circular Array
摘要
Abstract
Using the illumination formula of single LED wick and the symmetry of large LED circular array illumination distribution,a physical model for the illumination uniformity of large LED circular arrays is established.The uniformity of illumination of large LED circular array is derived.This formula is used to study the uniformity of illumination of large LED circular arrays with the array radius and the m values and the target distance.The uniformity of illumination no linearly increases with the increase of array radius,the uniformity of illumination no linearly increases with the increase of m value,the uniformity of illumination no linearly decreases with the increase of target distance.These rules provide theoretical basis for improving the uniformity of large LED circular arrays, the research direction and calculation method are provided for the illumination uniformity design of large LED circular array.It makes up for the lack of the uniformity of LED array illumination.关键词
