C78.1460-2004 (R2015) Page i 2015 National Electrical Manufacturers Association AMERICAN NATIONAL STANDARD Approval of an American National Standard requires verification

13、by the American National Standards Institute, Inc. (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. Cons

14、ensus 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 and

15、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, or pr

16、ocedures not conforming to the standards. It is intended as a guide to aid the manufacturer, the consumer, and the general public. ANSI does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or author

17、ity to issue an interpretation of an American National Standard in the name of the ANSI. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on this title page. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The

18、procedures of ANSI require that action be taken periodically to reaffirm, revise, or withdraw this standard.

26、efines the dimensional, physical, and other characteristics to assist in the proper application of tungsten-halogen lamps with GZ9.5 bases, T6 (T19) bulbs at 36.5 mm LCL and 76.2 mm maximum overall length with internal proximity reflectors. Lamps of various wattage and voltage designs are included.

27、The grouping of lamps in this standard is based on general physical characteristics. It does not imply that the lamps listed are interchangeable with each other in a particular application. Lamps included in this standard are intended for photographic projection applications.12 Normative References

28、The following standards contain provisions which, through reference in this text, constitute provisions of this American National Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this American National

29、Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

31、employed for the lamps described in this standard. 4 Physical characteristics 4.1 Base specifications Finished lamps employing the GZ9.5 base shall comply with the requirements given in ANSI C81.61. 4.2 Bulb designations 1Informative: In general, the lamps in this standard are compatible with those

32、in IEC Publication 60357. C78.1460-2004 (R2015) Page 2 2015 National Electrical Manufacturers Association Bulb designations are defined in ANSI C79.1. Due to the long-term use of the conventional method of designation, its use will continue herein. Equivalent metric designations are shown in parenth

33、esis, in contrast to the use of metric primary dimensions elsewhere in this standard. 4.3 Lamp characteristics Nominal electrical, physical, and other characteristics of standard lamps are listed in Table 1. 4.4 Dimensions 4.4.1 The lamp drawing of Figure 1 defines the various dimensions and provide

34、s specific values where appropriate. A typical product drawing is shown. Due to eccentricity and offset between the base and the bulb, the bulb may take up more room relative to the fixed position base. Dimension E is the radius of cylindrical space that defines the limit of bulb excursion relative

35、to the centerline between the base pins. The dimension LCL identifies the light center length and is a reference value. Dimension MOL is the maximum overall length. 4.4.2 The light source dimensions width (W), height (H), and thickness (T), define a volume centered on the light center length (LCL) a

36、nd the base centerline within which all luminous parts of the filament shall be located. This is a maximum volume accounting for all possible positions of the filament. Actual filament size may be significantly smaller than the defined light source volume. 4.5 Life The acceptability of life test res

37、ults shall be ascertained in accordance with ANSI C78.1450. 5 Restrictions 5.1 Operating position The lamps specified in this standard are restricted in operating position to that of base down through base horizontal position, unless noted otherwise in Table 1. 5.2 Seal temperature The lamps covered

38、 by this standard are limited in regards to the endurance of the metal-to-envelope seal. These lamps fall into two limiting classes; 400C maximum and 450C maximum. Table 2 shows the limitations of particular lamps. 5.3 Bulb wall temperature C78.1460-2004 (R2015) Page 3 2015 National Electrical Manuf

39、acturers Association The lamps bulb wall temperature shall be maintained above 250C for proper operation of the halogen cycle. An upper limit of approximately 900C is recommended for maintaining the integrity of fused silica bulbs. 5.4 Shielding A protective shield shall be provided relevant to the

40、following cautionary notice: - Tungsten-halogen lamps operate at high temperature and at internal gas pressures above atmospheric pressure. Consequently, a lamp could shatter. Certain lamps may also emit some amount of ultraviolet radiation. Therefore, a suitable protective shield, screening techniq

41、ue, or both, shall be used with the luminaire to protect people and surroundings from both hazards. - The information contained in the lamp manufacturers caution notice shall always be read and observed. 6 Test procedures 6.1 Life Lamps shall be tested in open racks, at the base-down operating posit

42、ion with cooling to maintain temperature limits. Additional procedures are defined in ANSI C78.1450. 6.2 Seal (pinch) temperature The measurement procedure is defined in ANSI/IEC C78.682. 6.3 Operating temperature Standard methods of measuring other lamp operating temperatures (bulb and base) are un

43、der consideration. 7 Information for luminaire design The proper luminaire design must take into account the several aspects of lamp restrictions mentioned in clause 4, operating position, seal temperature, bulb wall temperature, and shielding.
