4 Lamp requirements
4.1 General
A lamp, according to this document, shall comply with the requirements of IEC 62035.
Some lamps are specified on the data sheet or declared by the manufacturer as suitable for operation on low frequency square wave ballasts only. For these lamps, separate requirements are indicated where appropriate.
A lamp shall be so designed that its performance is reliable in normal and accepted use. In general, this can be achieved by satisfying the requirements of 4.2 to 4.9.
The requirements given apply to 95 % of production.
4.2 MarkIng
4.2.1 Colour appearance
A suitable advice on the colour appearance is required. It may preferably take the form of ILCOS (see IEC 61231). or the 3-digit code of IEC TR 62732. Other options are the manufacturer’s code or the correlated colour temperature. The information may be given either on the lamp or in the supplier’s catalogue.
4.4 Caps
The cap on a finished lamp shall comply with IEC 60061-1.
4.5 Starting and warm-up characteristics
4.5.1 Lamps that may operate on electromagnetic ballasts
A lamp shall start fully within the maximum run-up time specified on the relevant lamp data sheet and remain alight. Conditions and method of test are given in Annex A.
The maximum inrush current as given on the lamp data sheet shall not be exceeded. For the test circuit and procedure, see IEC 60923.
The lamp warm-up current shall be between the minimum and maximum values as given on the lamp data sheet. Conditions and method of test are given In Annex A.
NOTE The maximum Inrush current (peak) restricts the value of the current during rectification in the starting phase in order to prevent performance damages of ballast and lamp (overheating and melting of the electrodes), The reason for specifying the minimum warm-up current is to safeguard the transition from the glow phase to the
2t
4.5.2 Lamps suitable for low frequency square wave ballasts only
A lamp shall start and run up fully within the time specified on the lamp data sheet, applying the method of test given in E.3,1.
4.6 Electrical characteristics
The lamp electrical characteristics shall comply with the values given in the relevant lamp data sheet. Conditions and method of test are given in Annex B.
For lamps suitable for operation on low frequency square wave ballasts only, conditions and method of test are given In Annex E.
4.7 Photometric characteristics The photometric requirements are as follows.
a) The initial reading of the luminous flux shall be not less than 90 % of the rated value.
b) The initial reading of the centre beam intensity of a reflector lamp shall be not less than 75 % of the rated value.
C) The Initial beam angle of a reflector lamp shall be within ±25 % of the rated value for all beam angles.
d) Conditions and method of test are given in Annex B.
For lamps suitable for operation on low frequency square wave ballasts only, conditions and method of test are given in Annex E.
4.Z1 Useful luminous flux
The useful luminous flux of a directional lamp shall be measured under the conditions of Annex
B or Annex E as appropriate, by luminous intensity Integration as described In EN 13032-4:2015,
6.3 Partial luminous flux.
Alternative measurement methods may be used if they can be shown to give equivalent results for the product being tested, if necessary by applying correction factors. Measurements with lamps operating horizontally are often much easier to carry out. The reference method, however, uses the measurement position according to A,1.
In case of doubt a goniophotometry measurement of EN 1 3032-4:2015, 6.3 shall be used.
NOTE Below are a ew examples of alternative measurement methods. It Is not an exhaustive list.
• For snial beam angles shine into inteahng sphere.
• Mount lamp on internal surface of integrating sphere
• Mount lamp lnsde antegraung sphere with screening (LM-20 technique).
• Illuminate a surface and measure the illurninance across the surface with a photometer
• Illuminate a surface and measure the surface Itininanco with a luminance camera.
• Illuminate a translucent screen and measure the surface luminance of the rear side with a kiminance camera (]
4.8 Colour characteristics
4.8.1 Lamps with non-standardised chromaticity co-ordinates
The rated values and tolerance areas shall be assigned by the manufacturer or responsible
vendor.
4.8.2 Lamps with standardised chromaticity co-ordinates
The correlated colour temperature and chromaticity co-ordinates applicable to a certain lamp are given on the relevant lamp data sheet. A collation is given in Table B.1.
4.8.3 Colour rendering index
The initial reading of the general colour rendering index (Ra) of a lamp shall not be less than the nominal value decreased by 3.EN 61167-2018 pdf download.
