Mednarodni sistem za kodiranje sijalk (ILCOS) (IEC 61231:2010)
Ta mednarodni standard podaja pravila za mednarodni sistem za kodiranje sijalk in zajema vse kategorije sijalk, izvzemajoč sijalke na vozilih. Kodiranje je določeno za glavne vrste sijalk, za ostale pa bo primerno sledilo kot dopolnila tega standarda. Namen mednarodnega sistema za kodiranje svetilk je
- izboljšati komunikacijo o različnih vrstah sijalk;
- pomagati pri razpravah glede medsebojne zamenljivosti in združljivosti proizvodov;
- ustvarjanje tesnejšega povezovanja med mednarodnimi standardi in proizvajalčevo literaturo (na primer, v prihodnosti bi koda lahko bila podana v pomembnih delih standarda);
- omogočiti pravilno postavitev sijalk;
- da se uporablja kot komplementarno označevanje svetil;
- da zamenja državne in regijske kodirne sisteme.

INTERNATIONAL LAMP CODING SYSTEM (ILCOS)
FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61231 has been prepared by subcommittee 34A: Lamps, of IEC technical committee 34: Lamps and related equipment. This first edition cancels and replaces the second edition of IEC 61231, published as a technical specification. It constitutes a technical revision, of which the main changes are indicated below: – introduction of LED modules (Subclause 5.8). The text of this standard is based on the following documents: CDV Report on voting 34A/1345/CDV 34A/1374/RVC

61231 © IEC:2010 – 5 – INTRODUCTION The lamp industry strives continuously to meet customers' needs. Its innovative power has led to a tremendous variety of different light sources. To enable customers and experts to find their way within the diversity of products, a general system for the coding of lamps has been developed. The code does not replace specific markings used by individual manufacturers on their lamps or in their catalogues, but it is promoted for cross-referencing purposes and, in due course, to replace national and regional lamp coding systems which already exist. NOTE The code does not give all the technical characteristics necessary to specify a lamp fully. For this the relevant lamp standard and/or the manufacturer’s literature have to be consulted.
SIST EN 61231:2010
– 6 – 61231 © IEC:2010 INTERNATIONAL LAMP CODING SYSTEM (ILCOS)
1 Scope and object This International Standard gives the rules for the international lamp coding system and covers all lamp categories, excluding vehicle lamps. Coding for the main lamp types is specified and, for the others, will follow by amendments to this standard as appropriate. The object of the international lamp coding system is – to improve communication about the different types of lamps; – to help in discussions concerning interchangeability and compatibility of products; – to create a closer relationship between international standards and manufacturers’ literature (for example the code could be given in future in the relevant parts of a standard); – to enable correct replacements of lamps; – to be used as a complementary marking on the luminaire; – to replace national and regional coding systems. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60357, Tungsten halogen lamps (non-vehicle) – Performance specifications IEC 60432-1, Incandescent lamps – Safety specifications – Part 1: Tungsten filament lamps for domestic and similar general lighting purposes IEC 60432-2, Incandescent lamps – Safety specifications – Part 2: Tungsten halogen lamps for domestic and similar general lighting purposes IEC 60838-2-2, Miscellaneous lampholders – Part 2-2: Particular requirements – Connectors for LED-modules IEC/TR 60887, Glass bulb designation system for lamps IEC 61167, Metal halide lamps CIE publication 29.2, Guide on interior lighting 3 Principles The international lamp coding system has been developed on the basis of the following principles. – It should be manufacturer-independent concerning its content and its wording. – A relationship between the coding system and international standards should be established. SIST EN 61231:2010
61231 © IEC:2010 – 7 – – It should be internationally acceptable. It is recognized that other systems with national and regional importance exist and that the change to an international code should be seen as a long-term process.
– The length of the code should be as short as possible and as long as necessary. Therefore, it should be possible to use the code in different lengths depending on the different purposes. – In view of the technical diversity of the different lamp categories, it would not be practical to define the code for all types in the same way; the code depends therefore in its composition on the technical needs of the different lamp categories. – The code should not replace manufacturer-specific marking on the lamp or in the catalogues, but should be used for cross-references in lamp and luminaire literature. – The allocation of codes is based on interchangeability and compatibility. An additional usage of the code on the lamp package should be envisaged for the future.
4 Basic structure The complete lamp code ILCOS consists of a letter section and a figure section.
4.1 Letter section The first letter of the letter section designates the lamp category as follows: I Tungsten filament lamps H Tungsten halogen lamps (non-vehicle) F Fluorescent lamps S High-pressure sodium lamps L Low-pressure sodium lamps Q High-pressure mercury lamps M Metal halide lamps D LED modules X Special lamps NOTE Vehicle lamps, including their coding, are covered by national and/or regional legislation. The next letters within the letter section give further details as outlined in the description of the different lamp categories. The letter section is separated from the rest by a hyphen. 4.2 Figure section The figure section consists of several blocks mainly containing figures. Each block, separated by hyphens, contains characteristic values of lamps such as – wattage; – voltage; – lamp cap; – dimensional values. As a hyphen is used to separate the blocks, it cannot be applied within a block. As a consequence, the sign of equality = is used instead of the hyphen, for example within the cap designation.
The sequence and the specific content of the blocks is determined for each lamp category and described in 5.1 to 5.8. SIST EN 61231:2010
– 8 – 61231 © IEC:2010 4.3 Length of the code 4.3.1 General The code can be used in different lengths depending on the purpose. In catalogues and leaflets, specialities, for example special applications, can be indicated with an asterisk (*) in the place where the difference occurs or at the end of the code and explained in a separate remark, also indicated with an asterisk (*). The code can be shortened by deleting parts from the end, not by deleting intermediate parts. In general, if ‘standard’ types are concerned, the dimension block can be omitted. Intermediate parts may be omitted, providing the separating signs such as hyphens (–) and slashes (/) are given. NOTE These shortening rules do not apply to the extended short version ILCOS LE. 4.3.2 Short version: ILCOS L The short version consists of the letter section or a part of it and is called ILCOS L. It can be used for the general classification of lamps. A survey of ILCOS L is given in Annex A. 4.3.3 Extended short version: ILCOS LE The extended short version, where applicable, consists of the first part of the letter section (ILCOS L) immediately followed (without spaces) by the relevant dimensions. 4.3.4 Standard version: ILCOS D The standard version gives the complete designation and consists of the letter section and (a part of) the figure section. The use of ILCOS D should enable the customer to find the correct lamp type, for example in the case of lamp replacement from a different manufacturer. It can be used for the purpose of marking luminaires, when suitable also in an abbreviated form. SIST EN 61231:2010
