1. Introduction to LightProLightPro is a special view for placing luminaires within the context of the buildingmodel. The menus and toolbars for this view provide tools for placingluminaires, editing room lighting attributes and surface reflectances, and formaintaining the lighting database (see the Lighting database documentation).Luminaires may be placed singly or in arrays, and their beam centres may bepointed in any direction you required. The luminaires you place here may beused in FlucsPro and Radiance for artificial lighting calculations.

2. Lighting DatabaseThe program has access to the IES lighting database that holds informationabout luminaires and lamps. FlucsPro and Radiance use the information fromthe database for design or analysis purposes. An extensive system database isprovided but this can be supplemented with your own data.

Photometric data may be entered into the program either interactively or byimporting from photometric data files in standard CIBSE, EULUMDAT or IESNAformats. The standard CIBSE type-1 and type-2 formats are used and aredescribed in CIBSE TM14. For interactive input you describe the luminaire, thevalid lamps for the luminaire, and polar-curve data for luminous intensities.Optionally, light-output ratios, spacing-to-height ratios, utilisation factors, andglare indices may be entered or calculated. For lamps the lamp description and,optionally, lamp-lumen maintenance-factor curves are specified.

The program can calculate light-output ratios, spacing-to-height ratios, utilisationfactors, glare data and aspect factors and can perform LG3 checks and BZclassifications for a luminaire, based on the polar-curve information. The resultscan be viewed on the screen and output as hard copy if you wish.
