Luminaire Definition - Concepts
AGi32 uses a definition process to assign parameters to all luminaires before they can be used. The luminaire definition includes photometric information, descriptive information and a symbolic representation of the luminaire. Each occurrence of the luminaire will access these parameters in addition to the location and aiming information specified by the user. AGi32 places no limits on the number of luminaire definitions available in a job file.
The primary element in the luminaire definition is the photometric file associated with the luminaire. Without luminaire photometric information AGi32 cannot perform any electric lighting computations. Therefore, photometric files are essentially the catalyst required to make the software function. A substantial database of photometric information provided by many manufacturers can be found within the Instabase. Photometric information is also readily available from most luminaire manufacturer's websites.
Photometric files must follow one of several standardized formats. In North America, the photometric file format is authored by the Illuminating Engineering Society (IES). The filename extension for the IES format is .IES. More information on the IES Standard File Format (document LM-63-19) can be found at www.ies.org. In other parts of the world, there are other commonly used standard formats: CIBSE, United Kingdom (utilizes the .CIB, .CC, .CLS and .TML extensions) and EULUMDAT, Europe (utilizes the .EXL and.LDT extensions).
Relative photometry: AGi32 supports relative photometry in IES, EULUMDAT or CIBSE format. AGi32 supports CIBSE/1 format only.
Absolute photometry: AGi32 supports absolute photometric files in IES or EULUMDAT formats only.
