摘要:
A LED-based lighting apparatus (10) comprises a plurality of individual modules (16) which comprise each a LED unit (30) and a beam modifier (32) combined with each other. Any of the modules produces light with an individual intensity distribution which exhibits a two-fold symmetry about an optical axis (A) of the module, and has a peak value along two emission directions separated from the optical axis. All modules are arranged within the apparatus so that their optical axes are parallel to a common direction (Z), and with respective orientations which are evenly rotated in a plane perpendicular to the common direction.
摘要(中):
一种基于LED的照明装置(10)包括多个单独的模块(16),每个单独的模块(16)包括彼此组合的LED单元(30)和光束修改器(32)。 任何模块产生具有单个强度分布的光,其对于模块的光轴(A)呈现双重对称性,并且具有沿与光轴分离的两个发射方向的峰值。 所有模块布置在设备内,使得它们的光轴平行于公共方向(Z),并且具有在垂直于共同方向的平面中均匀旋转的各个取向。
