Sentence examples for luminance ratio from inspiring English sources

Results showed that simple luminance metrics (e.g. workplane luminance) & vertical eye illuminance outperformed complex glare indices (DGP/DGI) & luminance ratio.

To achieve a comfortable brightness balance, it is desirable to limit the luminance ratio between areas of appreciable size as seen from a normal viewing position.

When one block at the corner was turned on, and the others were turned off, the luminance ratio was ∼11.1 1 between the block and the nearest one, and ∼9000 1 between the block and the farthest one.
