摘要	A modular illumination system is capable of producing a light beam having a wide field of view - e.g., in excess of ninety degrees - while maintaining a high collection efficiency as well as a high degree of beam homogeneity. The illumination system comprises an elementary unit (300) having a linear array of light sources (306). Light from the light sources (306) is collimated using a corresponding array of catadioptric lenses (308), and the collimated light is homogenised in the tangential plane using two cylindrical lens arrays (304a, 304b) set in tandem to one another. The homogenised light is then collimated in the sagittal plane using a cylindrical lens (302) that is set perpendicular to the lenses of the two cylindrical lens arrays (304a, 304b) to yield a wide linear beam. To produce an area beam, the linear array of light sources (306) can be replaced with a two-dimensional array, and the cylindrical lenses (304a, 304b) can be replaced with spherical lenses.
其他摘要	模块化照明系统能够产生具有宽视场（例如，超过90度）的光束，同时保持高收集效率以及高度的光束均匀性。该照明系统包括具有线性光源阵列（306）的基本单元（300）。来自光源（306）的光使用相应的反射折射镜头阵列（308）进行准直，并且准直光在切向平面中使用彼此串联设置的两个柱面透镜阵列（304a，304b）均匀化。然后使用柱面透镜（302）在矢状平面中准直均匀化的光，柱面透镜（302）垂直于两个柱面透镜阵列（304a，304b）的透镜设置，以产生宽的线性光束。为了产生区域光束，可以用二维阵列代替线性光源阵列（306），并且可以用球面透镜代替柱面透镜（304a，304b）。
主权项	An illumination system, comprising: an array of light sources; one or more catadioptric lenses arranged to collect light from the array of light sources; a first array of lenses arranged in a first row that is substantially perpendicular to an optical path of light from the one or more catadioptric lenses; a second array of lenses arranged in a second row that is substantially parallel to the first row and substantially perpendicular to the optical path; and an output lens arranged to collect and project light from the second array of lenses to yield and output beam.
