16、ED FILE FORMAT FOR ELECTRONIC TRANSFER OF LUMINAIRE PHOTOMETRIC DATA In order to calculate the light striking a surface or leaving that surface from one or a group of man made and installed luminaires, it is necessary to know the light intensity distribution at all spherical angles from each luminai
17、re that contributes light to that surface. The advent of personal micro-computers has made it possible for each technical person to perform his own calculations using a suitable application program. It is common practice to record the light intensity at a large number of spherical angles from a spec
18、ific luminaire (photometric data set) onto magnetic media, such as a computer disk. While the standardization of the size, shape and other technical features between disks and computers has been done by others, it is necessary for the computer program reading data from the disk to know the sequence
19、of data being transmitted about the luminaire, light source, and angles at which the data has been recorded. This is termed the “file format“. While many countries, and companies within countries, have already adopted a specific file format it is necessary to have an international file format so tha
20、t the photometric data set specific to a particular country can be translated (by computer program) into the international file format; or that a photometric data set received in the international file format, can be translated (by computer program) into the specific file format used in a particular
21、 country or a specific application program developed by an individual or company. The CIE Recommended File Format is not intended to be used for manual calculations to determine the specific light intensity at a specific angle, but rather to be easily read, without error, into a computer program, ei
22、ther for translation into another format, or for calculation of the results of a lighting installation.

30、OTOMETRISCHEN LEUCHTENDATEN Um den Lichtstrom zu berechnen, der auf eine Oberflche auftritt oder von ihr reflektiert wird und der von einer oder mehreren Leuchten einer Anlage herrhrt, ist es erforderlich, die rumliche Lichtstrkeverteilung ber den Ausstrahlungswinkeln fr jede Leuchte zu kennen, die
31、Lichter auf diese Oberflche einstrahlt. Der Einsatz von Personal-Computern ermglicht es jedem Techniker, eigene Berechnungen mit einem geeigneten Anwendungsprogramm durchzufhren. Es ist gngige Praxis, die Lichtstrken einer Leuchte fr eine Vielzahl von Ausstrahlungswinkeln (photometrischer Daten-Satz

Da die Standardisierung der Gre, der Form und anderer technischer Eigenschaften von Diskette und Computer von Dritten durchgefhrt wurde, ist es erforderlich, da das Programm bei der Datenbemahme von der Diskette die Folge der Daten betreffend Leuch
33、te, Lampe und Ausstrahlungwinkel, unter denen die Lichtstrke erfat sind, erkennt. Dies wird “Datei-Aufbau“ genannt.

35、speziellen Anwendungsprogramms bersetzt werden kann, das ein einzelner oder eine Firma entwickelt hat.

37、993 I. Introduction A photometric laboratory may elect to use any format for the storage of photometric data relative to a particular luminaire that is best suited for their equipment and operating procedures. An application computer program may be designed to calculate any performance data such as
38、illuminance, luminance, hemispherical illuminance, or glare; and may elect to utilize any desired format for photometric data storage within that program that is most suitable to the calculations being performed. The interface that permits data to be transferred from the storage format of the photom
39、etric laboratory to the format of the application program can and should be defined by an international body, such as the CIE, so that photometric data taken by any laboratory in any country can be used in any appropriate application program developed by any user in any country. There may be an inte
40、rmediate stage of standardization within a single country or group of countries, in fact this exists at the time this document was generated, but there still remains a need for an international format to permit the standardized data of one country to be transferred into the international format and
41、then either used or transferred into the standardized data of another country. In either case cited above the producer of the photometric data needs to know only 2 photometric formats, his own and the CIE format. Likewise the user of the photometric data needs to know only two formats, the CIE forma
42、t and his own. There is no need for a producer to provide photometric data in a variety of formats suitable for use in a variety of application programs or suitable for use in a variety of countries. It should be understood that photometric data in the format described in this document is not intend
43、ed to be printed on paper and distributed for use in manual calculation procedures. It is intended that the transfer from one storage media, to another will be handled by computers and the transfer will occur in a few seconds or less. Computer programs can and should be written to convert photometri
44、c data from the CIE format into a form that can be printed, distributed and used for manual calculations. The language and printed format will then be in accordance with the language and needs of the individual country performing the conversion. i. i Limits of scope This document presents a recommen
45、ded photometric data file format for data transfer between computers and between a computer and some form of magnetic or optical storage media. The primary purpose envisioned is for the individual user to maintain an easily accessible file of photometric data for his use with lighting application co
46、mputer programs. In order to produce accurate lighting calculations the individual user of the application program must utilize the correct photometric data for the individual luminaires and must understand the relationship between the angular planes and cones and the geometry of the building or are
47、a where the luminaires are to be installed. Particular emphasis has been placed on the technique to be used in determining, for a luminaire with an asymmetric distribution, the method of identifying the location of the zero degree half plane and the zero degree cone. Both the person using the applic
48、ation program and the person installing the luminaire must be aware of the necessity of correctly handling this process. Other hardware or software issues such as magnetic storage medium formats, data transmission techniques, loss of data in transmission, operating systems, or programming languages
49、for conversion programs are beyond the scope of this document. Any one of these issues may need to be considered in the course of transferring photometric files from one producer or user to another. t COPYRIGHT International Commission on IlluminationLicensed by Information Handling ServicesCIE 202 93 900b145 0004739 7TL Publ.
