Abstract

A computer implemented method for illumination planning is provided that includes providing a floorplan having at least one lighting space; and assigning functions to the at least one lighting space. The lighting space and functions assigned to the lighting space of the floorplan are matched to a historical lighting schema. A lighting layout is extracted from the historical lighting schema and matched to the lighting space. A light package is extracted from the historical lighting schema and matched to the lighting space. A calculation of lighting performance for the lighting layout and the light package that has been matched to the lighting space is conducted to determine whether the lighting performance meets a lighting standard or whether the lighting performance does not meet the lighting standard. The computer implemented method further includes producing a conclusion for the lighting scenario for suitability to the floorplan and functions.

First claim

The invention claimed is:

1. A computer implemented method for illumination planning comprising:
providing a floorplan having at least one lighting space;
assigning functions to the at least one lighting space;
matching the lighting space and functions assigned to the at least one lighting space to a historical lighting scheme;
extracting a lighting layout from the historical lighting scheme that is matched to the at least one lighting space;
extracting a light package from the historical lighting scheme that is matched to the at least one lighting space;
calculating lighting performance for the lighting layout and the light package that has been matched to the at least one lighting space to determine whether the lighting performance meets a lighting standard or whether the lighting performance does not meet the lighting standard, wherein the calculating lighting performance comprises luminance:

where:
L v is the luminance (cd/m 2 ),
d 2 Φ v is the luminous flux (lm) leaving the area dΣ in any direction contained inside the solid angle dΩ Σ ,
dΣ is an infinitesimal area (m 2 ) of the source containing the specified point,
dΩ Σ is an infinitesimal solid angle (sr) containing the specified direction, and
θ Σ is the angle between the normal n Σ to the surface dΣ and the specified direction;
generating a conclusion for the lighting scenario for suitability to the floorplan and functions, the conclusion including a report for installation of the lighting layout and the light package when the lighting performance meets the lighting standard or the conclusion including a recalculation of lighting performance of at least one of a modified lighting layout and a modified light package to meet the lighting standard; and
installing the lighting layout and the light package.

2. The method of claim 1 , wherein the lighting package includes fixtures having a light source provided by at least one light emitting diode (LED).

3. The method of claim 1 , wherein the lighting performance is a measurement of illuminance.

4. The method of claim 3 , wherein when the calculating lighting performance for the lighting layout and the light package that has been matched to the at least one lighting space determines that the illuminance for the lighting performance is less than a requirement for the illuminance for the standard, the recalculation of the lighting performance comprises increasing an overall number of fixtures in the lighting layout for an entirety of the floorplan.

5. The method of claim 3 , wherein when the calculating lighting performance for the lighting layout and the light package that has been matched to the at least one lighting space determines that the illuminance for the lighting performance of a singular space in the floorplan is less than a requirement for the illuminance for the standard, the recalculation of the lighting performance comprises increasing a number of fixtures in a deficient area singular space of the floorplan.

6. The method of claim 1 , wherein the report for installation of the lighting layout and the light package includes installation instructions for light fixtures of the lighting package.

7. The method of claim 1 , wherein the lighting plan package includes light fixtures selected from the group consisting of hanging pendants, desk lamps, table lamps, floor lamps, chandelier lamps, recessed can downlights, track lighting, 2x2 tube lighting office type fixtures, 2x4 tube lighting office type fixtures and combinations thereof.

8. The method of claim 1 , wherein the lighting layout is a light location distribution type selected from the group consisting of a uniform layout, a centerline layout, a perimeter layout and a combination thereof.

9. A system for planning light illumination comprising:
an interface for receiving at least one of a floorplan having at least one lighting space, and assigned functions for the at least one lighting space;
memory for at least a database historical lighting schemes and a database of lighting fixtures;
a lighting device layout extractor for extracting a lighting layout from the historical lighting scheme matched to the lighting space;
a lighting space modeling tool for extracting a light package from the historical lighting scheme, and providing a lighting simulation for the lighting layout and the lighting package;
a lighting performance calculator for calculating lighting performance for the lighting layout and the light package to determine whether the lighting performance meets a lighting standard or whether the lighting performance does not meet the lighting standard, wherein the calculating lighting performance comprises luminance:

θ Σ is the angle between the normal n Σ to the surface dΣ and the specified direction;
a lighting adjustment calculator for when the lighting performance does not meet the lighting standard, wherein the lighting adjustment calculator modifies at least one of the lighting layout and the light package to provide at least one of a modified layout and modified package to meet the lighting standard;
a report generator for generating a reporting of lighting data selected from the group consisting of the lighting layout, the modified layout, the lighting package, the modified package and combinations thereof; and
