26、ICAN NATIONAL STANDARD ANSI C78.22-1995 American National Standard for Electric Lamps - Incandescent Lamps - A, Gy PS, and Similar Shapes with E39 Mogul Screw Bases 1 Scope This standard sets forth the physical and electrical characteristics of the group of incandescent lamps that have A, G, PS, and

27、 similar bulb shapes with E39 mogul screw (single- or double-wntact) bases. Only clear, inside frost, and white bulb finishes are acknowledged. Excluded from coverage are tungsten- halogen lamps and projection lamps. In addition to common-line voitage lamps, listed in Table 1 , a group of series bur

28、ning lamps rated at constant current are covered in Table 2. Other groups of incandescent lamps are covered in the following related standards: ANSI C78.20-1995, American National Standard for Electric Lamps - Incandescent Lamps - A, G, PS, and Similar Shapes with E26 Medium Screw Bases ANSI C78.21-

29、1995, American National Standard for Electric Lamps - Incandescent Lamps - PAR and R Shapes ANSI C78.23-1995, American National Standard for Electric Lamps - Incandescent Lamps - Miscellaneous Types At the time of issuance of this standard, there was no comparable standard published by the Internati

35、re utilized in this standard. 3.1 the top of the bulb. MOL (Maximum Overall Length): The distance along the lamps axis from the eyelet solder to 3.2 bases) to the center of the light-emitting area of the lamp. LCL (Light Center Length): The distance from the reference plane (eyelet solder for screw

36、3.3 finish, and filament type: including two or more voitage ratings within a voltage range. Class: A grouping of like lamps having the same rated wattage, bulb shape, base, MOL, bulb NOTE-Each line itern in Tables 1 and 2 is a dass. 3.4 Voltage range: A series of rated voltages related to commonly

37、available supply lines. NOTE-A foob-ote to Tables 1 and 2 lists several common voitage ranges appiying to ciassas of hmpc in this standard. 3.5 Rated wattage: The wattage marked on the lamp. 3.6 Rated voitage: The voltage matked on the lamp or declared by the manufacturer. NOTE-lf lamps are marked w

38、ith a range volage. it shall be interpreted that they are appropriate for uce on any line voltage within that range. Consult manufacture& catalog to determine design voltage. 3.7 Rated lumens: The lumen value marked on the lamp or declared by the manufacturer. 3.8 Rated current: The current value ma

39、rked on the lamp, if necessary. 3.9 Base temperature rise: The surface temperature rise (above ambient) of a standard test lampholder fitted to the lamp, when measured in accordance with the standard method. See Section 8 for methods of measurement. 3.10 this standard, is not necessarily the only ap

40、plication. Service: The field of most common application for a given lighting source. Service, as used in 4 Lamp designations This standard does not place any control over lamp designations. Incandescent lamps are generally designated by wattage and voltage ratings. Additional codes may be applied b

41、y the lamp manufacturer. See the lamp manufacturers catalog for detailed information. 5 Bulb designations Bulb designations used in this standard are defined in ANSI C79.1. Since the traditional eighth-inch sizes have long been utilized in some lamp designations, they are used in this standard. Thei

42、r metric versions are shown in parentheses. he is no attempt to identify or dassify filament type in this standard. 4 NEMA C78.22 95 6470247 0507229 049 ANSI C78.22-1995 6 Bulb finish Only lamps with clear, inside frost, or translucent white bulb finishes are considered in this standard. Silver bowl

43、, enamel, transparent, and other special coatings are not covered. 7 Lamp space drawings For each bulb- base- MOL category, the lamp space drawings in Part III of this standard show the maximum limits of the space that may be occupied by any part of the bulb. A typical bulb shape is shown, as a dash

44、ed line, within that maximum space. The space shown shall accommodate the longest and shortest lamps with maximum bowl and neck diameters, and maximum bulb eccentricity. These drawings were prepared in accordance with SR30a. The following general conditions apply to the construction of these space d

45、rawings: Straight lines are used as much as possible to simplify the space outlines. All compromises with the actual space are in excess of the actual space required. All excursions of a lamp bulb are shown relative to a fixed position base. Bulb eccentricity with respect to the base axis is a combi

46、nation of allowances for angular tilt (skewness) and lateral displacement (true eccentricity). An eccentricity angle of 3“ applies generally to incandescent lamps, unless special applications require tighter limits. The base contact-making gauge for each type of base controls the space near the rim

47、of the base in the base-to-neck transition zone. All dimensions are in millimeters unless otherwise specified. The figure numbers shown in Tables 1 and 2 under the column “Lamp Space Drawing“ relate directly to the former American National Standard for that category. For instance, Figure C78.22-214

48、was derived from the former standard ANSI C78.214-1949. 8 Methods of measurement 8.1 8.2 9 Electrical characteristics The values of lamp voltage, current, and wattage shown in Part II are those nominal values that apply after the lamps have been seasoned. (See IES LM54 for guidelines on lamp seasoni

49、ng.) 1 O Requirements 10.1 and special gauges, shall comply with C81.61 and ANSI C81.63. 10.2 in Tables 1 and 2. The method of measuring base temperature rise shall be as described in ANSI C78.25. A recommended method of electrical measurement of lamps can be found in IES LM45. Screw-shell type bases, including the E39 mogul screw and E39d double-contact mogul screw Individual lamps shall satisy the limits for MOL and LCL that apply to their lamp class as shown 5 NEMA C78.22 95 6470247 0507230 860 ANSI C78.22-1995 10.3 occupy a space within th
