具有改进的输出均匀性的LED照明装置
摘要：
本发明涉及LED照明装置。照明装置包括衬底和根据预定布局图案设置在衬底之上的多个LED模块。布局图案包括具有横向上邻近第一水平对准的LED模块和第二水平对准的LED模块定位的垂直对准的LED模块的行。布局图案还包括具有横向上邻近第一垂直对准的LED模块和第二垂直对准的LED模块定位的水平对准的LED模块的列。布局图案进一步包括横向上相互邻近的水平对准的LED模块的行。照明装置还包括：在多个LED模块之上设置的扩散器。每个LED模块还包括提供不对称光图案的次级光学组件。多个LED模块在扩散器上提供线性光分布或平面光分布。本发明还提供了一种具有改进的输出均匀性的LED照明装置。
摘要（英）：

The present disclosure involves an LED illumination apparatus. The illumination apparatus includes a substrate and a plurality of LED modules disposed over the substrate according to a predefined layout pattern. The layout pattern includes a row having a vertically-aligned LED module located laterally adjacent to a first horizontally-aligned LED module and a second horizontally-aligned LED module. The layout pattern also includes a column having a horizontally-aligned LED module located laterally adjacent to a first vertically-aligned LED module and a second vertically-aligned LED module. The layout pattern further includes a row of horizontally-aligned LED modules located laterally adjacent to one another. The illumination apparatus also includes a diffuser disposed over the plurality of LED modules. Each LED module also includes a secondary optical component providing an asymmetric light pattern. The plurality of LED modules provides a linear light distribution or a planar light distribution on the diffuser. The invention further provides an LED illumination apparatus with improved output uniformity.
