IEC 62384:2020 pdf download.DC or AC supplied electronic controlgear for LED modules – Performance requirements
1 Scope
This document specifies performance requirements for electronic controlgear for use on DC or AC supplies up to 1 000 V (alternating current at 50 Hz or 60 Hz) and with an output frequency which can deviate from the supply frequency, associated with LED modules according to IEC 62031. Controlgear for LED modules specified in this document are designed to provide constant voltage or current. Deviations from the pure voltage and current types do not exclude the gear from this document. NOTE 1 The tests in this document are type tests. Requirements for testing individual controlgear during production are not included. NOTE 2 Requirements for controlgear which incorporate means for varying the output power are under consideration. NOTE 3 It can be expected that controlgear complying with this document will ensure satisfactory operation between 92 % and 106 % of the rated supply voltage, taking into account the specifications of the LED module manufacturer.
3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 61347-1 and the following apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: IEC Electropedia: available at http://www.electropedia.org/ ISO Online browsing platform: available at http://www.iso.org/obp 3.1 total circuit power total power dissipated by controlgear and LED module(s) in combination, at rated supply voltage of the controlgear and at the highest rated output load 3.2 circuit power factor λ ratio of the measured circuit power to the product of the supply voltage (RMS) and the supply current (RMS)3.3 controlgear for LED module circuitry with high input capacitance controlgear suitable for LED modules which present high capacitance connected directly or indirectly to the input terminals Note 1 to entry: Examples are LED modules with switch mode power supply conversion circuits, like buck or boost regulators. Note 2 to entry: Typically, capacitances above 100 nF are considered high capacitance. 3.4 controlgear for LED module circuitry with low input capacitance controlgear suitable for LED modules which present low capacitance or no capacitance connected directly or indirectly to the input terminals Note 1 to entry: Examples are LED modules with only LEDs or with logic circuits intended for thermal protection, but not directly modifying the power supplied by the controlgear, or linear voltage regulators. Note 2 to entry: Typically, capacitances of 100 nF and below are considered low capacitance.
4 General notes on tests
4.1 The tests given in this document are type tests. The requirements and tolerances permitted by this document are based on testing of a type test sample submitted by the manufacturer for that purpose. In principle this type test sample should consist of units having characteristics typical of the manufacturer’s production and be as close to the production centre point values as possible. NOTE It can be expected with the tolerances given in this document that products manufactured in accordance with the type test sample will comply with this document for the majority of the production. Due to the production spread however, it is inevitable that there will sometimes be products outside the specified tolerances. For guidance on sampling plans and procedures for inspection by attributes, see IEC 60410. 4.2 For tests which are carried out with a LED module or LED modules, this (these) LED module(s) shall fulfil the following requirements: The power of the LED module(s) when measured at its (their) rated voltage or rated current (direct current and/or alternating current) shall not differ from the rated power by more than +6 % and –0 %. 4.3 4.4 4.5 The tests shall be carried out in the order of the clauses, unless otherwise specified. One specimen shall be subjected to all the tests. In general all the tests are made on each type of controlgear or, where a range of similar controlgear is involved for each rated power in the range or on a representative selection from the range as agreed with the manufacturer. 4.6 The tests shall be made under the conditions specified in Clause A.1. Since up to now data with regard to LED modules have not been published in an IEC standard, they shall be made available by the LED module manufacturer. 4.7 All controlgear covered by this document shall comply with the requirements of IEC 61347-2-13.
