Contents The presentation will look at standards Go onto what IEC 34 are working on List some SANS publications Setting urgent needs Suggesting a way forward and for these needs Electrical and photometric data required
Standards – why? Standardization, is there need for standards? The introduction of LEDs into the lighting market has and is making manufacturers and users rethink their lighting needs, test methods and the application of their existing equipment. The rethinking is helped along its way due to the world-wide energy shortage and in particular here in South Africa. The goals of standardization can be to help with independence of single suppliers (commoditization), compatibility, interoperability, safety, repeatability or quality. Standards ensure desirable characteristics of products and services such as quality, environmental friendliness, safety, reliability, efficiency and interchangeability and at an economical cost.
Standards - types Standards for products are broadly divided into two categories namely that of Safety and Performance. Safety - Safety standards deal with the requirements that will ensure that the products are safe and will not cause harm to the user or the users building when used as recommended. Safety standards offer the tests and test methods to verify that the products are compliant. These safety standards may cover a wide range of products. Performance - Performance standards deal with the way that the product performs under a test situation. However as quote from Wikipedia, The existence of a published standard does not necessarily imply that it is useful or correct. Just because an item is stamped with a standard number does not, by itself, indicate that the item is fit for any particular use. The people who use the item or service (engineers, trade unions, etc.) or specify it (building codes, government, industry, etc.) have the responsibility to consider the available standards, specify the correct one, enforce compliance, and use the item correctly. Validation of suitability is necessary.
LED Standard Terminology The IEC has published some Standards and two Public Available Specifications (PAS). The need for the PAS documents is because these have not been accepted as full Standards but have information that is very useful. These documents suggest that the following quality criteria should be considered when evaluating LED manufacturers claims: a) Rated input power b) Rated luminous flux c) LED luminaire efficacy d) Luminous intensity distribution e) Photometric code or the values of the next four measurements f) Correlated Colour Temperature (CCT) g) Rated Colour Rendering Index (CRI) h) Rated chromaticity co-ordinate values both initial and maintained i) Lumen maintenance code j) Rated life (in h) of the LED module and the associated rated lumen maintenance (Lx) k) Failure fraction (Fy), corresponding to the rated life of the LED module in the luminaire l) Ambient temperature (tq) for a luminaire

This SANS document, by reference, forms part of the Compulsory specification for electrical and electronic apparatus, as published by Government Notice No. R. 89 (Government Gazette 31844) of 6 February 2009. SANS compulsory Standards
LED Standards required 1. LED replacements for 50 mm diameter Quartz Halogen lamps – Dichroic lamps 2. LED floodlights lamps – replacement for PAR 38 120W 3. LED floodlights lamps – replacement 300W 500W 1000W linear quartz halogen lamps 4. LED linear lamps – replacement for 600mm, 1200mm, 1500mm tubular fluorescent lamps 5. LED luminaires for above, and 6. High bay luminaires 7. Street lanterns
LED replacements for 50 mm diameter Quartz Halogen lamps – Dichroic lamps Eskom Standard used in the Residential Mass Roll out (RMR) based on IEC 62612 Self-ballasted LED Lamps for General Lighting Services >50V, Performance Requirement (edition 1) Needs to be amended Light output is to be added to be consider for a rebate 50W QH lamp replacement lamp shall have a light output of 600 to 800 lumens 35W QH lamp replacement lamp shall have a light output of 300 to 500 lumens Tolerance allowed 5% and the power of the lamp used to calculate the rebate. Colour of lamps warm white 2800 plus tolerance ±7% Other?
Cool White Intensity, Beam angle and Colour Warm White Pure White Quartz Halogen White
LED floodlights lamps – replacement for PAR 38 120W and LED floodlights lamps – replacement 300W 500W 1000W linear quartz halogen lamps Existing IEC LED lamp standards could be used. Mass of LED lamp is high and the lamp holders should be checked.
Replacement lamps 1550 grams and 800 g Note LEDs on top of left not burning and the heat sink material
LED linear lamps – replacement for 600mm, 1200mm, 1500mm tubular fluorescent lamps These have the same challenges as the T5 retrofit and the SANS/IEC 60598 should be amended to include the G13 lamp cap but there is an IEC draft for LED tubular lamps and this is recommended to be used. The IEC LED draft offers a better solution as it looks at LEDs and their test systems. Test facilities may need to be arranged and hence if this is used as a guide or ARP and later become a VC
IEC draft Double-capped LED lamps for general lighting services –Safety specifications 1 Scope This International Standard specifies the safety and interchangeability requirements, and the exchange operation together with the test methods and conditions required to show compliance of double-capped LED lamps with caps G5 and G13, intended for replacing fluorescent lamps with the same caps, having: – a rated power up to 60 W; – a rated voltage of up to 250 V; Such LED lamps are designed for replacement without requiring any modification of the luminaire. The existing luminaires into which the double-capped LED lamps are fitted, can be operated with electromagnetic or electronic control gear. The requirements of this standard relate only to type testing. Recommendations for whole product testing or batch testing are given in Annex A.
Typical information 5.3.2 Graphical instruction (IEC Draft) This clause can be used instead of 5.3.3. The steps of applying the product to an existing luminaire shall be as given in Figure 8. Switch off – remove - replace - connect - switch on Figure 8: Schematic steps of removing a fluorescent lamp and inserting a double-capped LED lamp Note no safety circuit shown – SA will require a safety fuse this is in the text of IEC draft
Proposed Guide lines LED Tubular lamps 1. Use the T5 retrofit guide lines as the min basis 2. Labels three off positions in retrofit 3. Circuit diagrams shown with changes 4. Luminaire tested with lamps especially retrofit 5. LED replacement lamps not recommended for emergency luminaires as a refit but recommend new luminaires are used here. 6. Zone classified luminaires must be retested with the LED lamps and certificates provided. 7. All luminaires tested to have photometric data available.
LED luminaires for above, High bay luminaires and Street lanterns Used the amended SANS/IEC 60598 safety and call for SANS 475 testing for performance data. Phase this is but issue a working guide so that Users can specify correctly and manufacturers can compete on an equal basis. Street light standard is the most urgent followed by high bay luminaires for stores.
LED modules – replaceable?
Light output and life All LEDs must state the light output initial value and the value at 1000 hours, 2000 hours and 15000 hours. The LED survival must be 2% failure before 1000 hours 5 % at 2000 hours and not more than 50% AT 15000 hours. L70F50 15000 h=max 50%lamps having lumen maintenance below 70% after 15000 hours and L85F05 1000h = h=max 5%lamps having lumen maintenance below 85% after 1000 hours CRI greater than 80 Efficacy NDLS 65 lm/W DLS 55 lm/W and increasing Ref European LED Quality Charter Batch testing is required.
Electrical – power and power factor?
Conclusion This is a quick proposal of ideas but South Africa requires these Standards or guidance so that the local industry can establish themselves, importers can bring in safe and efficient LEDs and products, inter-changeability can be achieved with reliable service for users Users can specify products fairly and get competitive prices. Stock holding can be limited
