【摘要】 LED已经广泛渗透到大众生活的照明、指示、通信、定位等众多领域。特别是在可见光通信领域，LED自身的空间辐射特性主导了其在不同可见光通信场景的实际性能。实际上，如何基于不同类别、不同复杂程度的光源辐射特性解析模型，平滑地实现LED光波束三维建模及直观展示，仍然缺少针对性的阐述和讨论。面向各类新型光源应用对LED空间辐射特性的表征实验需求，本文提出了面向LED朗伯辐射特性、对称非朗伯辐射特性以及非对称非朗伯辐射特性空间建模及直观展示的仿真实验方法。该方法能够满足商用迥异LED光波束的三维展示需求，同时能够满足对LED空间辐射特性进行针对性地二维剖析需求。此外，上述工作为后续开展可见光通信组合光波束的优化设计提供了路径和便利。更多还原

【Abstract】 To public life, LED has widely penetrated into many fields including lighting, indication, communication, and positioning. And particularly in visible light communication(VLC) domain, the spatial radiation characteristics of LED dominate the actual performance in various VLC application scenarios. As a matter of fact, there is still no relevant explanation and discussion on how to realize the 3D modeling and visual display of LED beams smoothly based on the analytical model of radiation characteristics with distinct categories and complexity. In this work, one simulation experiment solution was proposed for the spatial modeling and visual display of LED Lambertian beams, non-Lambertian beams and hybrid beams. This solution could meet the 3D display requirements of commercial distinct LED beams, and meet the requirements of two-dimensional cross section analysis to LED spatial radiation characteristics. In addition, above work presents the path and convenience for the future VLC optimization design of combing optical beams.更多还原
