description	An illumination system is disclosed that is arranged to compensate for variations in brightness between different LEDs in the system. The system may include an array of LEDs coupled to a light guide that is provided with a plurality of light extraction patterns. Each light extraction pattern may include a plurality of light extraction features. The light extraction patterns may differ from one another in the density of the features. Light extraction patterns having a greater density may be combined with LEDs in the array that are less bright, whereas light extraction patterns having a lower feature density may be combined with LEDs in the array that are brighter. 公开了一种光照系统，其被布置为补偿系统中的不同LED之间的亮度变化。该系统可以包括耦合到光导的LED的阵列，其中光导被提供有多个光提取图案。每个光提取图案可以包括多个光提取特征。光提取图案可以在特征的密度方面彼此不同。具有更大密度的光提取图案可以与阵列中的不太亮的LED组合，而具有更低特征密度的光提取图案可以与阵列中的更亮的LED组合。
