2、National Standard Lighting Group For Electric Lamps- High-Intensity Discharge Lamps, Method of Designation An American National Standard implies a consensus of those substantially concerned with its scope and provisions. It is intended as a guide to aid the manufacturer, the consumer, and the genera

3、l public. The existence of an American National Standard does not in any respect preclude anyone, whether he has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. Users are cautioned to obtain the lat

4、est editions. The American National Standards Institute 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 authority to issue an interpretation of an American National Standard in the name of t

The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of Ameri

7、 Approval 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. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agree

8、ment 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 objections be considered, and that a concerted effort be made toward their resolution. The use of Am

21、pyright 2007 by American National Standard Lighting Group Page 4 of 16 ANSI_ANSLG C78.380-2007 Proposed Revision of ANSI C78.380-2005 1 Scope This standard describes a system for the designation of high-intensity discharge lamps, including compact, enclosed-arc discharge light sources such as mercur

22、y, metal halide, high-pressure sodium, and similar types of lamps. For convenience, low-pressure sodium lamps, although technically not high-intensity discharge lamps, are included with the group. There have been two changes since the 2005 standard. The first is a proposed addendum for the National

23、Electric Code (NEC) as a normative annex for the assignment of physical codes for lamp and luminaire attributes. The second is a proposed amendment to C78.380i- a revision of paragraph 7 and addition of a new paragraph 8. 2 Purpose The purpose of the designation system covered by this standard is to

24、 provide an identification code for use in ANSI standards. Some lamp marking requirements are also identified. Guidance is given as to which characteristics are important (key) to assure interchangeability. The lamp characteristic data given by a manufacturer on a High-Intensity Discharge Lamp Code

25、Designation (LCD) Request Form becomes the basis for the assignment of a designation. They have not been approved by the American National Standards Institute (ANSI) and do not constitute an American National Standard. Similarly, any consolidated listing of assigned designations with associated char

26、acteristics does not constitute an American National Standard. 3 Normative references The following standards contain provisions, which through reference in this text, constitute provisions of this American National Standard.

31、 American National Standard (In the context of this publication only) “Once a lamp code designation is published in an ANSI-approved C78 standard” (see 7.5) Electrical interchangeability - The ability to properly install a replacement lamp in a particular installation where electrical characteristic

32、s of lamps and luminaires are compatible in regard to characteristics such as voltage, current, power, open circuit voltage, etc. Physical interchangeability - The ability to properly install a replacement lamp in a particular installation, based on physical characteristics such as base type, bulb s

33、ize, lamp length, etc. Key characteristic - A characteristic identified as having a critical effect on the interchangeability of lamps. Alternative design - A lamp with key characteristics that are the same but utilize different features that do not affect interchangeability. Designation program - T

34、he procedures and requirements of this standard formulated to provide designations for lamps. Reflector lamp - A discharge lamp in which part of the bulb, of suitable shape, is coated with a reflecting material so as to control the light. Note: HID reflector lamps typically employ R or PAR-shaped bu

35、lbs. Lamp manufacturer - A manufacturer who produces finished lamps and offers them for sale. Sponsor - The originator of a Lamp Designation Request Form. 5 Description of a designation 5.1 General A lamp designation code shall consist of a combination of letters and numbers in the following sequenc

36、e: Lamp Type Classification Letter Electrical Characteristic Number Luminaire Characteristic Letter Quartz and Ceramic Metal Halide Lamps shall be marked with all three items. Other HID lamp types shall be marked with the first two items. Other lamp types may also be marked with the luminaire charac

37、teristic letter. Consult the lamp manufacturer before use on ballasts with any code that is not listed on the lamp.

One set of numbers is the source for all assignments of Characteristic numbers and Characteristic numbers can be used for more than one lamp classification type as long as the additional type conforms to the key electrical characteristics for an additional type in An

They represented a set of key physical characteristics of the lamp in question, so as to ensure physical interchangeability. These code letters are no longer u
