中文摘要：
以GaN基功率型发光二极管（LED）为代表的半导体照明光源，具有其他传统光源无法比拟的诸多优点，被公认为21世纪最有价值的新型光源。充分发挥功率型LED的优势，利用非成像光学进行面向实际应用的功率型LED封装光学系统设计，以高端半导体照明光源的制造为突破点，带动整个半导体照明产业的快速进步，已成为半导体照明技术发展的战略选择。回顾了非成像光学的历史、研究进展以及在半导体照明中的应用，并通过设计实例，介绍了面向功率型LED光线耦合、二维给定光分布以及三维给定光分布问题的非成像光学系统设计原理与解决方案。
英文摘要：
Solid state lighting sources based on GaN-based high power light emitting diodes （LEDs） have been considered as one of the most valuable light sources in 21th century due to its many unparalleled advantages over other conventional lighting sources. It is a sensible strategy choice to promote the developments of solid state lighting industrial progress by making a breakthrough at some high class solid state lighting products, which can utilize the advantages of high power LEDs through introducing revolutionary design ideas based on non-imaging optics. In this paper, the history and development of non-imaging optics and its application in solid state lighting are reviewed. Then, the non-imaging optical system design principles and practical solutions are given through a few samples including optical system design of bundles-coupling, two-dimentional （2D） prescribed light distribution and 3-dimentional prescribed light distribution problems based on LEDs.
