Why We Use LM 79 Testing ITC India Lab?

LM 79 testing lab provides a snapshot of performance under specified operating conditions at some point in the life of a product, usually, at the beginning of the operation, these are referred to as initial measurements. It never addresses permanent ratings, changing performance over time e.g, lumen maintenance, or LED case temperature.

• The LM 79 methods are really applicable to integrated LED products, such as luminaries and replacement lamps. It is not applicable to LED packages, modules, or arrays
• LM 79 is the method for testing electrical and photometric measurements of SSL 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 Testing Laboratories applied to LED products that incorporate control electronics and heat sinks. This covers complete LED luminaries and integrated LED sources. It does not include bare LED chips or LED-based products without a light source.

What Is Important Aspect Of LM 79 Testing?

LM 79 testing requires complete luminaries testing on an absolute photometric basis. Typically lighting products are evaluated on a relative photometric basis, where separate tests are done for lamps luminaries. However, for SSL products the LED lamps typically cannot be separated from their luminaries. The absolute photometric testing required measures the light distribution and light intensity of the complete luminaries.
In recent times, the term LM 79 Testing laboratories have become part of our lighting lexicon and have been treated in some cases as lighting program all its own. While many lighting programs such as DLC and Energy Star reference LM 79 procedures, it is not in and of itself a lighting program with specified requirements and pass/ fails criteria.

However, the term LM-79 Testing Lab has come to generally be recognized as two distinct tests – a candela distribution test with an IES file, and an integrating sphere test for a standard color CCT, CRI, Duv, chromaticity coordinates. Nevertheless, anytime LM 79 is mentioned in reference to the desired testing, our staff will verify exactly what the customer requires since many measurement options are discussed in the official document.

What is TM 21?

What is TM 21? How it is different from LM 80 and LM 79?

In this topic, we are going to discuss “What is TM 21”? “ How it is different from LM 80 and LM 79?”

LEDs are like other light sources, see their output decline over time. However, given the remarkably long life of LEDs and the absence of visible signs indicating their decreasing performance, it can be more complex to accurately measure and communicate light output over time. To help address this issue, the Illuminating Engineering Society of North American (IESNA) and the Environmental Protection Agency (EPA) have put in place standards for reporting the useful lifetime of an LED package: LM-80 (Measuring Luminous Flux and Color Maintenance of LED Packages, Arrays and Modules) and TM-21(Projecting long-term Lumen Maintenance of LED Light Sources).

TM-21 outlines a standard calculation method to predict future lumen depreciation using LM-80 data. These standards apply to lifetime projection of LED package, array or module alone.

TM 21 uses the below data of LM 80 for calculation (Lumen maintenance)

1. Sample size and calculation data
2. It is encouraging to adopt short interval and longtime data
3. Two calculations：
   • At the same burning conditions
   • The temperature of the actual temperature testing point
4. The calculation from the same burning conditions
   • data collection and pre-processing
   • calculation tool
   • results
   • same process at the different temperatures

5. The calculation from the actual temperature testing point –
   • The actual temperature is between two temperatures getting from the data, for example, let us have an Lm 80 data

[caption id="" align="alignnone" width="516"] Lm 80 data[/caption]

Step 1: Normalize and average all data

• Use all data
  • LM 80 requires 6,000 hours with data at 1,000-hour increments
  • TM 21 applies all the test data at any increment
• Normalize all data to 1 (100 %) at 0 hours
• Average each point for all samples of the device for each test conditions
  • The average is done for the simplicity of the application
  • Variance associated with multiple samples is not considered usable for projection.

Step 2 : Sample Size

[caption id="" align="alignnone" width="624"] Sample Size[/caption]

Step 3: Use the latest data for the curve fit

Step 4: Curve fit and projection

Step 5: Adjust results (X- times rule)

Step 6 Interpolation of the result

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.
