Five such cycles shall be carried out. You may not copy or “mirror” iecc file or printed version of the document, or any part of it, for any other purpose without permission in writing from IEC. For undated references, the latest edition of the referenced document including any amendments applies. General requirements and tests.
Marking according to one of both columns is required. These performance requirements are additional to the requirements in IEC for self-ballasted LED lamps NOTE 1 safety standard When operated in a luminaire the claimed performance data can deviate from the values established via this standard. The actual LED behavior with regard to lumen maintenance may differ considerably per type and per manufacturer.
At the end of this time, and after cooling down to room temperature, the lamp shall remain alight for at least 15 min.
Both elements are tested. See also the text under Ice 11 with regard to the indicated percentage of tested lamps of a total batch F50 or F10 that may fail the irc of the test. Comments and observations to the comments were considered at that meeting and are incorporated in the CD.
The value and the conditions are specified in this standard, or assigned by the manufacturer or responsible vendor 3. This will give additional insight as to the reliability of the measured values.
IEC System of Conformity Assessment Schemes
Additionally, the following references are applicable: A fast initial decrease in lumen output does not automatically imply that a particular LED will not make its rated life. The harmonic content is defined as the R. All LED lamps in the test sample must pass these post treatment criteria. Dedicated information on the chosen percentage is to be provided by the manufacturer. For normative references, see IEC Ief 2 The actual luminous intensity coupled to a specific beam angle is not an element of this performance standard, but the related luminous flux from which the beam intensity and angle are eic is subject of iex testing; via calculation it can be determined whether the rated luminous intensities are realistic within the beam angle specified by the manufacturer.
Note Method of measuring the luminous flux of LED lamps is under discussion. NOTE 1 LED lamps have a different end of life characteristic than conventional lamps, because they are not subject to sudden lamp failure but will typically dim over time in a gradual way. At uec end of these tests a and b 626122 LED lamp shall operate and remain alight for 15 min and show no physical effects of the temperature cycling such as cracks or delaminating of the label.
Life is always published in combination with the failure rate see NOTE 4 and 3. Stable operation has been reached when the temperature of the LED lamp is not increasing more than 5 K per h.
Unless otherwise specified for a specific purpose by the manufacturer or responsible vendor, lamps shall be operated in free air in a vertical base-up position for all tests including lumen maintenance tests. For non-professional purposes, 6262 Aand for professional purposes, column B is applicable.
Recommendations for whole product testing or batch testing are 622612 consideration.
Annex B has been reserved for a description of an improved method as compared to CIE L70, F50 or L50, F For compliance with EMC requirements reference is made to regional requirements. In addition the following definitions are given. Both will not 622612 repeated here.
B Product datasheets 1 or leaflets x x x c Rated life and the related lumen maintenance factor Lx e Failure rate Fxcorresponding to the rated life f Lumen maintenance category Cat A to E, see Clause NOTE 2 The built-in electronic driver, however, may show a sudden end of life failure. In the case of a voltage range, measurements shall be carried out at the mean value. Lamps which are intended for retrofit purposes shall be equipped with adequate means of ice.
For dated references, only the edition cited applies. Reference is made to document CIE For that reason this standards relies on approximation methods to determine the expected life L50 or L70 of any self-ballasted LED lamp.

The definition under 3. Tolerances are based on the CIE MacAdam ellipses as normally applied for compact fluorescent lamps and other discharge lamps. It is permitted to download this electronic file, to make a copy and to print out the content for the sole purpose of preparing National Committee positions. A self-ballasted LED-lamp is considered having passed the test when the following criteria have been met: All tests shall be carried out at rated frequency.
