17、tion. ? LE 6-2009 Page ii Foreword This standards publication was developed to assist individuals purchasing or designing lighting systems for interior or exterior applications in determining the Target Efficacy Rating (TER) of a lighting product. The TER is intended to be a metric, among many other
18、 considerations, to evaluate the energy effectiveness of a lighting installation. This standards publication was promoted by the need of the luminaire manufacturing industry to have a uniform method of determining energy effectiveness of their products. The NEMA LE 6-2009 Standard supersedes the NEM
19、A LE 5, LE 5A, and LE 5B Standards for Luminaire Efficacy Ratings (LER). It is not the intent of this standards publication to inhibit luminaire design or to impose arbitrary tolerances on any luminaire manufacturer. Further, it is not the intent of this standards publication to be used to regulate
20、luminaires since many other factors related to visibility, color, contrast, glare, uniformity, and other metrics must be considered based on application requirements. The preparation of this standards publication was done by the Luminaire Section, in close cooperation with the Lamp and Ballast Secti
21、ons of the NEMA Lighting Systems Division. Input of users and other interested parties has been sought and evaluated. Inquiries, comments, and proposed or recommended revisions should be submitted to the Indoor Lighting Section of NEMA by contacting: Vice President, Technical Services National Elect
22、rical Manufacturers Association 1300 North 17th Street, Suite 1752 Rosslyn, Virginia 22209 This standard was developed by the Luminaire Section. Section approval of the Standard does not necessarily imply that all section members voted for its approval or participated in its development. At the time
23、 it was approved, the Luminaire Section was composed of the following members: Acuity Brands Lighting Arcalux Corporation BJB Electric Cooper Lighting Deco Lighting Emerson/EGS Electrical Group EYE Lighting International GE Consumer & Industrial Lighting Systems Hubbell Lighting, Inc.
