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

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

  • Total luminous flux
  • Electrical powers
  • Luminous Intensity distribution
  • Efficacy (lm/watt)
  • Chromaticity

How To do Photometric Testing?

Check Our Photometric Testing Scope

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
  3. For SSL products, LED lamps typically cannot be separated from their luminaire because of heat effects

Relative vs. Absolute Photometry

Relative testing – Lamps of interest and luminaire are measured separately. Then the actual light distribution and intensity of the complete luminaire of interest is derived by normalization of the test data

Absolute testing – The actual light distribution and intensity of the luminaire of interest is measured directly from the complete luminaire.

LM-79 Definition and Scope

IES LM-79 is an approved method for testing electrical and photometric measurements of solid-state lighting products. LM-79 contains procedures for performing reproducible measurements of LEDs properties, including: total flux, electrical power, efficacy and chromaticity.

The scope of LM-79 applies to LED products that incorporate control electronics and heat sinks. This covers complete LED luminaires and integrated LED sources. It does not include bare LED chips or LED based products without a light source.

LM-79 testing requires complete luminaire testing on an absolute photometric basis. Typically lighting products are evaluated on a relative photometric basis, where separate tests are done for lamps an luminaires. However, for solid state lighting products the LED lamps typically cannot be separated from their luminaires. The absolute photometric testing required measures the light distribution and light intensity of the complete luminaire.

LM-79 Procedures and Conditions

  • Ambient Conditions
  • Maintain temperature at 25 degrees C +/-1 degree C (within 1M)
  • Mounting – limit thermal transfer
  • Limited air flow
  • Power Supply
  • AC waveshape limit to harmonic RMS of 3%
  • Voltage regulation to +/- 2%
  • Seasoning and Stabilization
  • Testing Orientation
  • Electrical Settings
  • Instrumentation

LM-79 Testing Methods

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.

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.

LM-79 Test Outputs and Calculations

  • Total Luminous Flux
  • Luminous Intensity Distribution
  • Electrical Power
  • Luminous Efficacy
  • Chromaticity
  • CCT
  • CRI

LM-79 Testing, Lm 79 Test report, LM 79 Test procedure, India

ITC India is a NABL accredited laboratory in discipline of Electrical (T-1811), Electronics (T-3509) and photometry (T-3510), serving its satisfied customers for last 5 years. Laboratory is fully equipped with the highly accurate Machines to test LM 79. It owns a Integrating sphere as well as the Goniophotometer.  Qualified and experienced engineer are appointed to perform the desired tests.

Gone are those days when we use incandescence (tungsten filament) or fluorescent (mercury atoms) bulb. They are replaced by LED’s Now; this is an era of SSL (LED) as ……There is innumerable reason for the rise in LED’s which cannot be counted on finger tips. It is beneficial to both USERS as well as to the nation. Its superior features make it so promising that one cannot deny using LED’s.  The features of LED’s are, its low power consumption, digitally controllable,   Low maintenance, Ultra long source life, no UV or IR radiations, No mercury content. SSL uses semiconductors material to convert Electricity into light.  LED’s are non carbon materials.

Efficacy is the quality parameter for LED: it is measure in Lumen per watt. Higher efficacy means high energy efficient. Another quality factor is lifetime and last but not the least is Color rendering Index (CRI). CRI measures the ability of light source to reproduce the color of various objects in comparison with natural light source.

How LM-79 testing can help assess LED luminaries quality and performance?

AS LM79 report provides you with the Photometric as well as electrical parameters with a spectrum Test report. The photometric parameters are luminous flux, Efficacy and Radiant Power, CIE colorimetric Parameters (coordinates Color rendering Index (CRI), color coordinate Temperature (CCT) Duv Value, and light Intensity Distribution .Current, Voltage, Power factor, Power and frequency are the electrical parameters. It Focus on the efficiency and CRI, which are the quality parameter. Efficiency measures how much electrical energy is converting into light energy. Power factor is another electrical metric for LED driver performance and often a key parameter for street lighting due to the large number of these luminaries connected to the power grid.  As far as for lifetime, LM 80 covers that part.

What is the LM-79 test methodology?

 LM 79 is approved method to test Photometric and electrical measurements of Solid state lightning. It describes the procedure and precaution to be observed during measurements. This approved method covers LED based SSL products with control electronics and heat sinks incorporated, that is , those devices that require only AC main power or a DC voltage power supply to operate. This document does not covers SSL products that require external operating circuits, or external heat sink. LM 79 covers SSL product in a form of luminaries (fixture incorporating light source) as well as integrated LED lamps.

Why do we need it?

We need it to access the quality and other parameters due to increasing competition in the market. It provides the efficiency and power factor.   

How is LM-79 different from other test methods used for conventional lighting products?

This approved method is a guide developed for the measurements of SSL products. While many other standards for photometric measurements of light sources and luminaries are available, these standards are separated for measurements of lamps and luminaries. Since the current SSL products are in the form of luminaries or lamps, and LED light source in luminaries are not easily separated as replaceable lamps, these existing standard cannot be applied directly to SSL products. This necessitates the use of absolute photometry. This test method uses absolute photometry where as other standard uses relative photometry in short.

Now lets us clear about relative and absolute photometry.

S.NO Absolute Photometry Relative Photometry
1 Total lumen output of a luminary (bulb with fixture) Total Lumen output of a bare lamp is measured.
2 Method used to measure LED performance. Method used to measure Bare bulb and system performance.
3 Output is relative to an easy measured condition.

 

Output is measured in calibrated units under specific operating and environment conditions, ambient temperature, input voltage and orientation.
4 Specific lamp performance does not matter,

 

Lamps and system performance matters.

 

5 Use for SSL products For NON SSL products

What are the LM-79 test outcomes?

The outcome of the LM 79 is the REPORT providing all the required parameters as per LM 79.

They are ……

  1. CIE colorimetric parameters
  2. Chromaticity coordinate (x)
  3. Chromaticity coordinate (y)
  4. Chromaticity coordinate (u’)
  5. Chromaticity coordinate (v)
  6. Chromaticity coordinate (v’)

  20. Test information

Ambient Temperature, Stabilization Time, Total Operating Time, Sphere Dia, Photometric method or instrument used Wavelength range in nm of spectroradiometer.

Along with this a SPECTRUM TEST REPORT is also issued.

What are the limitations of LM-79?

  • Chips, Packages, or Modules requiring external heat sinks or operating circuits are not covered
  • Does not state the sampling size.

Is there a future scope for improvement in the LM-79 test?

Yes of course, there is always a scope for improvement in all areas.

Range/criteria of acceptance of CCT, CRI & Lumens may be defining to establish a harmonization of parameters globally.
