Inputs

Room length m Enter a numeric project value in m at or above 0.1. Room width m Enter a numeric project value in m at or above 0.1. Maximum x spacing m Enter a numeric project value in m at or above 0.01. Maximum y spacing m Enter a numeric project value in m at or above 0.01. Length edge offset m Enter a numeric project value in m at or above 0. Width edge offset m Enter a numeric project value in m at or above 0.

Obstacles

Add one row for each relevant space, item, zone, document, or measurement set.

Row 1

Obstacle type Enter the project label, note, or reference used for this calculation. Obstacle origin x m Enter a numeric project value in m at or above 0. Obstacle origin y m Enter a numeric project value in m at or above 0. Obstacle width m Enter a numeric project value in m at or above 0.01. Obstacle height m Enter a numeric project value in m at or above 0.01. Clearance around obstacle m Enter a numeric project value in m at or above 0.

Important notes

Record the obstacle type and confirm final positions against structure, services, access, and product instructions.
Australian standards may inform the planning boundary; this tool does not certify compliance.

Formulas

\(\displaystyle P_{valid} = P_{grid} \setminus \bigcup O_i^{clearance}\)
\(\displaystyle S_{actual} = (L-2O)/(n-1)\)
Obstacle clearance is an editable planning rule, not a universal installation rule.

Classify regular grid positions against explicit obstacle clearances.

Lighting Layout Obstacle Avoidance Tool is a planning aid. Keep the target source, product data, measurement method, and project assumptions with the result. Confirm compliance, installation, certification, and safety decisions with the responsible professional.
