8、 of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. An American National Standard implies a consensus of those substantially concerned with its scope and provisions
9、. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views
10、 and objections be considered, and that a concerted effort be made toward their resolution. The existence of an American National Standard does not in any respect preclude anyone, whether s/he has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes,

26、American National Standard Lighting Group- NEMA 1300 North 17th Street Suite 1847, Rosslyn, VA 22209 5American National Standard Two-inch (51mm) Dichroic Coated Integral Reflector, Rim Reference, Tungsten Halogen Large Screen Projection Lamps with GX5.3 Bases 1 Scope This standard consolidates previ
27、ous standards for certain low voltage two-inch (51mm) dichroic coated integral reflector, rim reference tungsten halogen lamp types with GX5.3 bases designed for large screen projection systems and used in 8mm projection, 16mm projection, slide projector, photo enlarger, and printing applications. T
28、he lamp types contained in this standard are not to be considered as interchangeable although they will all physically fit into two-inch integral rim reference centering systems and common GX5.3 lampholders. Photometry performance of each lamp depends upon the photometry appraisal system for which i
29、t was designed as well as the system in which the lamp is used. Photometry appraisal and end use systems may or may not be the same. Two-inch (51mm) integral reflector, rim reference tungsten halogen lamps with GX5.3 bases having ANSI lamp designations, DDM, EJL, ELB, and ELC are included in this St
30、andard. 2 Normative References The following standards contain provisions which through reference in this text constitute provisions of this American National Standard. At the time of publication of this Standard edition dates of normative reference standards were valid. However, all reference stand
31、ards are subject to revision, and parties to agreements based on this American National Standard are encouraged to determine and apply the most recent editions of the normative reference standards listed below.

Tungsten-halogen lamps operate at high temperature and at internal gas pressures above atmospheric pressure. C
40、onsequently, a lamp could shatter. Certain lamps may also emit some amount of ultraviolet radiation. Therefore a suitable protective shield, screening technique, or both shall be used with the luminaire to protect people and surroundings from both hazards. 2. Always read and observe the information

43、 88.2 Illumination See ANSI IT7.201, Slide Projectors and Filmstrip Projectors-Illumination Test, or ISO 11315-1, Photography Projection in Indoor Rooms, Part 1; Screen Illumination Test for Still Projectors. Illumination from large screen projection lamps in this standard is typically measured usin
44、g large screen photometry appraisal with lamps placed in aperture and lens systems that simulate projectors. See Figure A1 in Annex A for typical projection systems used for screen photometry of lamps in this standard. Light from lamps converges and passes through a rectangular aperture and projecti
45、on lens, and is formed into a rectangular image proportional in size to the aperture. A condenser lens may also be used between the lamp and aperture. This image is projected onto a large screen equipped with photocells for measurement of both light intensity and uniformity with the distance from th
46、e lamp to screen determined by the desired image size on the screen. Light Cellsw3Corner Cells3h6ww265 wh5 h6h2h6wFigure 2 Typical Photocell Location for Large Screen Photometry A typical image screen, as shown in Figure 2, has thirteen photocells that measure light intensity in lux or lumens per sq
47、uare meter. Light intensity is measured by the nine light cells in centers of nine equal area elements with area elements and photocell location determined by the screen width and height. Total light intensity in screen lumens is the average light intensity at each light photocell multiplied by the
48、total screen area in square meters. Thus total light in screen lumens is independentANSI C78.1433-2001 Consolidation and Revision of ANSI C78.1409-1991, ANSI C78.1410-1991, ANSI C78.1411-1991and C78.1414-1988 Copyright 2001 by American National Standard Lighting Group- NEMA 1300 North 17th Street Su

Uniformity in terms of corner-to-center ratio is measured by the center light cell and the four corner cells. Corner cell location, also determined by screen width and height, may vary among different set-ups. All lamp performance characteristics in Table 2, projection systems, and large screen photometry set-ups are typical but may vary among different lamp manufacturers. 8.3 Seal Temperature Measurement
