摘要

Reconstruction of a daylight simulator at ICA, Slovak Academy of Sciences in Bratislava requires precise alignment of the lamps with emphasis to imitate faithfully the conditions under CIE skies. Therefore, it is important to thoroughly know the characteristics and emission function of used luminaires, their position, orientation and by stepwise calibration reach the desired luminance distribution on the hemisphere. Up to now, existing luminaires with high energy consumption will be replaced by LED lighting with specific characteristics. This contribution is focused on testing the effective calculation method of the luminance distribution on the dome to reach ISO/CIE sky types for the unique sky simulator. So-called ray-tracing method with adaptive data regression is used tested and compared with fisheye images, while the interreflection is taking into account.
