ITCIndia NABL Approved Electrical Safety Testing Laboratory, ITCIndia Laboratory is following the procedure as required by International Standard IEC 17025 and is already certified for ISO 17025 by NABL , has been awarded accreditation by the National Accreditation Board for Testing and Calibration Laboratories (NABL). Under the Energy Efficient Lighting Products Program. This includes LM-79 accreditation for Solid State Lighting Luminaires, Total Flux Measurements (Luminous Efficacy) & Solid State Lighting Luminaires, Luminous Intensity Measurements.

Definition of LM-79 Testing:

LM-79 is one approved method that describes procedures & precautions in performing measurement of LED products.

Scope of IES LM-79 testing:

LM-79 Testing is applied to solid-state lighting products that include the following requirements:

  • LED based products that are integrated control circuit and heat sinks
  • LED based products only requiring AC or DC power supply

And does not cover as bellow:

  • LED products requiring external operating circuits or heat sinks (bare LED chips, package and modules)
  • Fixtures designed for LED products but sold without a light source

 

Electrical Requirements:

  • SSL products work with AC power: voltage, electrical current, power, frequency, power factor
  • SSL products work with DC power: voltage, electrical current, power

Test Condition and Procedures/ LM-79 Procedures and Conditions:

  1. Ambient Conditions

  • Temperature–maintaining at 25℃±1℃ / Maintain temperature at 25 degrees C +/-1 degree C (within 1M)
  • Air Flow—limited/ Limited air flow
  • Mounting–limited thermal transfer

 

  1. Power Supply

  • Voltage regulation to +/- 2%
  • Voltage waveform (harmonic distortion< 3%) / AC wave shape limit to harmonic RMS of 3%
  1. Aging and Stabilization/ Seasoning and Stabilization

  • New SSL products can be put into tested without aging.
  • Before testing, SSL products should work for a certain time to reach up stable working temperature.
  1. Working Orientation/ Testing Orientation

  2. Electrical Settings

  3. Instrumentation

Test Method of Lm-79/ LM-79 Test Methods:

Integrating Sphere and Goniophotometer available to achieve the test report

Integrating Sphere: Integrating sphere systems are used to measure the total luminous flux and color for LM-79. This can be performed with a photometer (total luminous flux) or a spectral radiometer (spectral radiant flux). Utilizing a spectral radiometer and integrating sphere is the preferred method, which derives total luminous flux and color qualities form spectral radiant flux measurements. Click here to see (Video) how to do LM-79 Test with Integrating sphere systems

  • For measuring total luminous flux and color
  • Photometer – Total Luminous Flux
  • Spectral Radiometer (preferred) – Spectral Radiant
  • Flux (to derive total luminous flux and color qualities)

Goniophometer :  Goniophotometer systems are also used for LM-79 testing to measure luminous intensity distribution. The Goniophotometer system tests derive total luminous flux and provide color characteristics including CCT and CRI.

  • For measuring luminous intensity distribution
  • Total luminous flux is derived
  • Provides color characteristics with spectral radiometer including CCT, CRI

What is LM-79 Luminaire Testing?

LM-79 Luminaire Testing

LM-79-08. It is the Illuminating Engineering Society of North America (IESNA) approved method for the Electrical and Photometric Measurements of Solid-State Lighting. It measures an LED luminaire or integral lamp as a whole system according to a standard process using specified equipment.

IES LM-79 Electrical and Photometric Measurements of Solid-State Lighting Products

Approved method describing procedures and precautions in performing reproducible measurements of LED Lights:

  1. Total luminous flux
  2. Electrical powers
  3. Luminous Intensity distribution
  4. Efficacy (lm/watt)
  5. Chromaticity

LM-79 Luminaire Testing Scope:

Applies to LED-based products incorporating control electronics and heat sinks, that is, those devices that require only AC mains power or a DC voltage power supply to operate.

Absolute Photometry Basis:

  1. LM-79 requires complete luminaire testing
  2. Traditionally, photometric evaluation of lighting products is based on separate tests for lamps and luminaires (Relative)
  3. For SSL products, LED lamps typically cannot be separated from their luminaire because of heat effects (Absolute)

Relative vs. Absolute Photometry:

  1. Relative testing – Lamps of interest and luminaire (with reference lamp) are measured separately. Then the actual light distribution and intensity of the complete luminaire of interest is derived by normalization of the test data
  2. Absolute testing – The actual light distribution and intensity of the luminaire of interest is measured directly from the complete luminaire.
