ANSI C78.50-2016 Page i AMERICAN NATIONAL STANDARD Appro

12、val of an American National Standard requires verification 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

13、substantially concerned with its scope and provisions. 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 ne

14、cessarily unanimity. Consensus requires that all views 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,

15、 marketing, purchasing, or using products, processes, or procedures not conforming to the standards. It is intended as a guide to aid the manufacturer, the consumer, and the general public. The American National Standards Institute, Inc., does not develop standards and will in no circumstances give

16、an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute, Inc. Requests for interpretations should be addressed to the secretariat or

17、 sponsor whose name appears on this title page. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute, Inc., require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purcha

35、s, some terms common to the industry are utilized in this standard and in Table 1. 3.1 MOL (Maximum Overall Length): Distance along the lamp axis from the furthest base extension (eyelet solder for screw bases) to the top or face of the lamp. Dimensions are included in this document. 3.2 LCL (Light

36、Center Length): Distance from the reference plane (eyelet solder for screw bases) to the center of the light-emitting element of the lamp. 3.3 class: A grouping of like lamps having the same lamp shape, base, MOL, and lamp finish, including two or more voltage ratings within a voltage range. Each li

37、ne item in Table 1 is a class. 3.4 voltage range: A series of rated voltages related to commonly available supply lines. Table 3 lists several common voltage ranges that apply to classes of lamps in this standard. 3.5 rated lamp power (wattage): Lamp power marked on the lamp. 3.6 rated voltage: The

38、voltage marked on the lamp. If lamps are marked with a range voltage, it shall be interpreted that they are appropriate for use on any line voltage within that range. 3.7 base temperature rise: The surface temperature rise above ambient temperature of a standard test lampholder fitted to the lamp, w

39、hen measured according to the standard method. Maximum base temperature rise limits apply to base-up burn position at which maximum temperature rise occurs unless lamps are restricted to other burn positions by their manufacturers. See ANSI C78.60360 for method of measurement. 3.8 service: The field

40、 of most common application for a given lighting source. Service indicated in this standard is not necessarily the only application. “Spotlight” and “floodlight” are examples of generic terms used only to describe either spot or floodlight service. Other examples include dry, damp, wet, and rough se

41、rvice applications. 4 Lamp Designations This standard does not place any control over lamp designations. This standard recognizes that SSL lamp standards are not fully developed. Additional codes may be applied by lamp manufacturers. See lamp manufacturers catalogs for more detailed information. 5 L

42、amp Shape Designations Lamp shape designations used in this standard are defined within ANSI C78.79 and used in Table 1. The traditional eighth-inch system of designation has been used in this standard (for example, PAR16 = 2 inches in diameter). The metric equivalents are also shown. 6 Beam Photome

43、try and Classification for Directional Sources See ANSI C78.379 for information on classification of beam patterns. For directional light sources, the guidance provided in C78.379 should be utilized. 7 Lamp Drawings Lamp drawings in Part III of this standard show the maximum limits of the space that

44、 may be occupied by any part of the lamp. A typical lamp shape is shown as a dashed line within that maximum space. The ANSI C78.50-2016 Page 3 2016 National Electrical Manufacturers Association space shown shall accommodate the longest and shortest lamps with maximum bowl and neck diameters and max

45、imum lamp shape eccentricity. These drawings were prepared in accordance with the lamp space drawing procedures in ANSI C78.30. The following general conditions apply to the construction of these space drawings: a. Straight lines are used as much as possible to simplify the space outlines. All compr

46、omises with the actual space are in excess of the actual space required. b. All excursions of a lamp shape are shown relative to a fixed-position base. c. Lamp eccentricity with respect to the base axis is a combination of allowances for angular tilt (skewness) and lateral displacement (true eccentr

47、icity). An eccentricity angle of 3 applies generally to incandescent lamps unless special applications require tighter limits. d. The base contact-making gauge for each type of base controls the space near the rim of the base in the base-to-neck transition zone. e. All dimensions are in millimeters

48、unless otherwise specified. 8 Electrical Characteristics The values of supply voltage to the ANSI base (see C81.61), shown in Part II, are those nominal values for the lamp. 9 Requirements 9.1 Bases and gauges shall be as described in ANSI C81.61 and C81.63. Each lamp manufacturer must ensure that lamp weight and moment are acceptab
