The objective of

15、 this NEMA standard is to provide suggested minimum performance levels for SSL retrofit products. The retrofit market being the first market introduction for most consumers, it is critical that the products being offered meet a minimum standard for form, fit and function, so as to not disappoint or

16、discourage market acceptance and growth. Federal programs such as Energy Star set high performance goals to encourage growth of such products, but do not provide minimum acceptance criteria for products as a whole. Dozens, even hundreds of standards exist for illumination technology, and many of the

17、se may be applied to SSL if an examination is first made to determine correct application. This document seeks to call out, tailor and consolidate these performance parameters as able, either by reference or direct quote. In the preparation of this standards publication, input of users and other int

18、erested parties has been sought and evaluated. Inquiries, comments, and proposed or recommended revisions should be submitted to the concerned NEMA product Subdivision by contacting: Vice President, Technical Services National Electrical Manufacturers Association 1300 North 17th Street, Suite 1752 R

GENERAL 1.1 SCOPE This standards publication applies to integral Light Emitting Diode (LED) lamps, which are defined as a lamp with LEDs, an integrated LED driver, and a base that meets ap

20、propriate American National Standards (ANSs) and is designed to connect to the branch circuit via a lampholder/socket that meets appropriate ANSs. The criteria herein apply to both integral LED lamps of non-standard form, and those intended to replace standard general service incandescent lamps, dec

21、orative (candelabra style) lamps, and reflector lamps. Other types of replacement lamps may be added in the future as improvements to LED technology make LED use in other replacement lamp types viable. 1.2 REFERENCES The following normative documents contain provisions, which through reference in th

22、is text constitute provisions of this standards publication. By reference herein these publications are adopted, in whole or in part as indicated, in this standards publication. These referenced documents are available from the organizations below. Integral LED lamps shall comply with the relevant c

The color rendering index (CRI) is def

30、ined in terms of a comparison of the spectral tri-stimulus values of the objects under test illumination and standard illumination according to the recommendations of CIE Publication No.13.31995. 6) Correlated Color Temperature (CCT): The actual color of the LED is called the color temperature and i

31、s defined in terms of the spectral tri-stimulus values (color coordinates) according to the recommendations of IESNA LM-16-93.
