Preface
This is the fifth edition of CSA C653, Photometric performance of roadway and street lighting luminaires. It supersedes the previous editions published in 2013, 2008, 1994, and 1992.
This Standard establishes the minimum performance requirements for roadway and street lighting luminaires.
The requirements of this Standard are in addition to those specified in Canadian Electrical Code, Part I; CSA C22.2 No. 250.0, Luminaires; and CAN/CSA-C22.2 NO. 250.13, Light emitting diodes (LEDs) equipment for lighting applications.
The major change to this edition includes updating the maximum UPD levels.
CSA acknowledges that the development of this Standard was made possible, in part, by the financial support of BC Hydro, the Canadian Electricity Association, Hydro-Québec, Manitoba Hydro, Natural Resources Canada, and the Ontario Ministry of Energy.
This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
Scope
1.1
This Standard specifies photometric performance requirements for luminaires that are used for roadway and street lighting applications as a function of unit power density (UPD).
1.2
The following light sources are addressed in this Standard:
a) clear HPS lamp
b) clear metal halide lamp and
c) LED.
1.3
This Standard is based on
a) average luminance, luminance uniformity ratio, and veiling luminance ratio as defined in ANSI/IES RP-8;
b) nominal input power in watts for HID sources;
c) rated lamp lumens for HID sources;
d) relative photometry for HID sources as per ANSI/IES LM-63 and IES LM-31
e) luminaire input power in watts and rated luminaire lumens for LED sources and does not include constant light output (CLO) applications; and
f) absolute photometry for LED sources as per IES LM-79.
1.4
This Standard is not a design document, and is intended to establish luminaire photometric performance efficiency only, based upon typical roadway configuration.
Tables 4, 5, and 6 are intended to be used to establish maximum UPD values for typical applications as per the parameters listed in Table 1. UPD values provided in this Standard are not intended for specification or application purposes.
User specific road geometries could differ from the templates used in the creation of these Tables. Requirements of specific designs might necessitate different variations in distribution, lumen packages, and wattages. Users should review UPD as a measure of comparison across suppliers, within their own geometry, and should note that UPD levels will then vary from the Tables within this Standard.
1.5
In this Standard, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the Standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as requirements.
Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
1.6
The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
