79 FOREWORD

80 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national

81 electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all

82 questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities,

83 IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS)

84 and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC

85 National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental

86 and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with

87 the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between

88 the two organizations.

89 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus

90 of opinion on the relevant subjects since each technical committee has representation from all interested IEC National

91 Committees.

92 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in

93 that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC

94 cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.

95 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to

96 the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and

97 the corresponding national or regional publication shall be clearly indicated in the latter.

98 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment

99 services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by

100 independent certification bodies.

101 6) All users should ensure that they have the latest edition of this publication.

102 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of

103 its technical committees and IEC National Committees for any personal injury, property damage or other damage of any

104 nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication,

105 use of, or reliance upon, this IEC Publication or any other IEC Publications.

106 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable

107 for the correct application of this publication.

108 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights.

109 IEC shall not be held responsible for identifying any or all such patent rights.

110 International Standard IEC 62722-2-1 has been prepared by subcommittee 34D: Luminaires, of IEC

111 technical committee 34: Lamps and related equipment.

112 This second edition of IEC 62722-2-1 cancels and replaces IEC 62722-2-1 first edition published in

113 2014. This edition constitutes a technical revision.

114 This edition includes the following significant technical changes with respect to the previous edition.

115 1) Alignment with IEC 62717:2014 + A1:2015 + A2:2019

116 2) Clarification of temperature requirement for the maintenance test, Clause 10.2 and Annex A

117 3) New annex C on methods for calculation and measurements of parameters for extension of

118 electric and photometric data.

135 INTRODUCTION

136 This document acknowledges the need for relevant tests for luminaires using LED as an electrical light

137 source. The publication is seen in close context with simultaneously developed and edited publication

138 of performance standards for luminaires in general and for LED modules. This document does not

139 consider luminaires designed for LED lamps, which are covered in IEC 62722-1. Changes in the LED

140 luminaires standard will have impact on the LED module standards and vice versa, due to the behaviour

141 of LED. Therefore, in the development of the present document, mutual consultancy of experts of both

142 products has taken place.

143 The provisions in this document represent the technical knowledge of experts from the fields of the

144 semiconductor (LED chip) industry and of those of the traditional electrical light sources and luminaires.

145 As this document has been simultaneously developed and edited with the standard for LED modules

146 (IEC 62717), where appropriate the compliance of the LED modules to the provisions of IEC 62717 can

147 be transferred to the whole luminaire.

149 LUMINAIRE PERFORMANCE –
150
151 Part 2-1: Particular requirements for LED luminaires
152
153 1 Scope

154 This part of IEC 62722 specifies the performance requirements for LED luminaires, together with the

155 test methods and conditions. It applies to LED luminaires for general lighting purposes.

156 Semi-luminaires are not covered under the scope of this document.

157 For some types of luminaires (e.g. decorative/household) the provision of performance data under the

158 scope of this document is not appropriate
159 The following types of LED luminaires are distinguished.

160 Type A – Luminaires using LED modules where evidence of compliance with IEC 62717 is given.

161 Type B – Luminaires using LED modules where no evidence of compliance with IEC 62717 is given.

162 Luminaires using a LED lamp are covered in IEC 62722-1 and not by this document.

163 The requirements of this document only relate to type testing.

164 This document covers LED luminaires using LED modules, based on inorganic LED technology that

165 produces white light. It does not cover luminaires using light sources based on OLED technology

166 (organic LED technology).

167 Life time of LED luminaires is in most cases much longer than the practical test times. Consequently,

168 verification of manufacturer’s life time claims is out of the scope of this document.

169 Instead of life time validation, this document has opted for lumen maintenance categories at a defined

170 finite test time. Therefore, the category number does not imply a prediction of achievable life time. The

171 categories are lumen-depreciation character categories showing behaviour in agreement with

172 manufacturer’s information which is provided before the test is started.
173 2 Normative references

174 The following documents, in whole or in part, are normatively referenced in this document and are

175 indispensable for its application. For dated references, only the edition cited applies. For undated

232 5 General requirements

233 Performance requirements given in this document are additional to the requirements in IEC 62722-1,

234 except where in this document alternative methods of measurement or limits are specified.

235 Luminaires are considered within the same family if they have:

236 – LED modules with the same method of control and operation (semi-integrated, integrated);

237 – LED modules with the same classification according to the method of installation (reference is made

238 to IEC 62031:2018, Clause 4) and using LED module of same family as specified in 6.2 of

239 IEC 62717:2014 + A1:2015 + A2:2019 and the same class of protection against electrical shock;

240 – the same design characteristics distinguished by common features of materials, components, and/or

241 method of processing and heat management.
242 6 Test conditions
243 6.1 General test conditions

244 Test conditions for testing electrical and photometric characteristics, lumen maintenance and life are

245 given in Annex A. For a luminaire in a family of luminaires as described in clause 5, the electrical and

246 photometric data may be calculated. When calculations are used or when alternative colorimetric data

247 is derived, the methods and conditions given in annex C shall be used. Annex C is only valid in case of

248 luminaires where a single LED module is used or where all the LED modules are identical. The

249 applicability of Annex C to light source where the light colour is obtained by mixing different spectra

250 emitted by different light sources needs more considerations than those provided by this annex.

251 All tests are measured on “n” LED luminaires of the same type. The number “n” shall be a minimum of

252 products as given in Table 3. LED luminaires used in the endurance tests shall not be used in other

253 tests.

254 Each sample luminaire shall comply with all the relevant tests except for the tests of 10.3 where one

255 sample is required for each of the three separate tests mentioned in Table 2 and Table 3. In order to

256 reduce the time of testing, the manufacturer or responsible vendor may submit additional luminaires or

257 parts of luminaires provided that these are of the same materials and design as the original luminaire

258 and that the results of the test are the same as if carried out on an identical luminaire.

IEC CDV 62722-2-1 © IEC 2021 10 34D/1648/CDV

259 LED luminaires with dimming control shall be adjusted to maximum output for all tests.

260 LED luminaires with adjustable CCT shall be adjusted/set to one fixed value as indicated by the

261 manufacturer or responsible vendor.

262 LED luminaires of linear geometry and variable length shall be tested at a length at which the parameters

263 are given (e.g. performance per x cm).

264 6.2 Luminaires using LED modules where evidence of compliance with IEC 62717 is given

265 (Type A)

266 Only the tests for measurement of initial performance as detailed in 6.4 are to be conducted, when the

267 LED module is operated within its temperature limit tp.

268 The information for luminaire design given in IEC 62717:2014 + A1:2015 + A2:2019, Clause B.1,

269 requires LED modules to be operated within their t temperature limit. The t temperature shall be

p p

270 measured according to the thermal test procedure defined in 12.4 of IEC 60598-1, (normal operation).

271 When the luminaire is operating at its own maximum rated ambient performance temperature value (t ),

272 the t limit (for the declared performance – Table 2, IEC 62717:2014 + A1:2015 + A2:2019) of LED

273 modules operating inside the luminaire shall not be exceeded. The test voltage for the luminaire shall

274 be 1,00 times the rated voltage of the luminaire. In luminaires intended to be supplied with constant

275 current, the test current shall be 1,00 times the rated current of the luminaire.

276 For luminaires for road and street lighting and floodlights intended for outdoor use only, the reduction

277 of the measured temperature according to 3.12.1 of IEC 60598-2-3, and 5.12.1 of IEC 60598-2-5,

278 respectively shall not be applied for the t temperature of the LED module.

279 The ambient performance temperature t is measured in a draught-proof enclosure, as the air

280 temperature, at a position near one of the perforated walls on a level with the centre of the luminaire,

281 see item e), Clause K.1 of IEC 60598-1.
