A tool used to determine the optimal spacing and positioning of flush-mounted luminaires within a room. It considers factors such as ceiling height, room dimensions, light output of the fixtures, and desired illuminance levels to ensure even and adequate illumination. These instruments often employ mathematical formulas and photometric data to provide users with specific layout recommendations.
Proper luminaire planning offers considerable advantages. It minimizes shadows and dark spots, improving visual comfort and task performance. Furthermore, it can reduce energy consumption by optimizing the number of fixtures needed to achieve the desired lighting effect. The need for such calculated layouts arose as recessed lighting became a popular choice for both residential and commercial spaces, replacing traditional, more easily positioned lighting fixtures.
