Thermal test is one of the important tests while testing LED luminaries, so we would like to have its basic knowledge.
Thermal test is performed for normal and abnormal conditions. We will peep inside both the conditions respectively.
The motive of thermal test is that the Lamp, part of the luminary, supply wiring, mounting surface should not attain the temperature which can cause injury. The parts like handles should not be too hot to be touched. Same scenario is for the track mounted luminaries are there. Track mounted Luminaries are tested as per clause 12.4.1. Draught proof chamber is specially designed for this particular test. While performing the test, the through wiring and the looping in wiring shall be loaded to the maximum value allowed by the size of the wire, or at a value prescribed by the manufacturer in the installation instructions.
After the test, none of the temperature shall exceed the values given in table 12.1 & 12.2 of IEC 60598-1.
While performing the thermal test in abnormal condition, luminaries are tested in abnormal conditions. The temperature shall not exceed as mentioned in table 12.3, 12.4, and 12.5. If the luminary possesses motor, the test is performed in most critical condition.
Clause 12.6 is applied to the luminary classified for mounting on normally flammable surfaces with a control gear. Clause 12.7 is thermal test in regard to fault conditions in lamp control gear or electronics devices incorporated in thermoplastics luminaries.
Temperature Measurement Data as per client specification
The sample was operated until constant temperatures were obtained. A temperature was considered
constant if the sample was operating for at least three hours and upon three successive readings – taken at
15 minute intervals – were within one degree and were not rising.
Thermocouples were attached at locations described in the results by means of cement made of water

What is LM 79 Test methodology?
What is LM 79 Test methodology?
LM 79 is an approved method that describes the procedure to be followed and precautions to be observed in performing reproducible measurements of total Luminous flux, electrical power, luminous intensity distribution, chromaticity of Solid-State lighting products for illumination purposes under standard conditions.
LM 79 covers- LED based SSL products with control electronics and heat sinks. Luminaries (fixtures incorporating light source) as well integrated LED lamps.
LM 79 doesn’t cover– fixtures without a light source, SSL products that require external operating.
LM 79
Test method for total luminous flux Measurements:
The total luminous flux of SSL product shall be measured with an Integrating Sphere or Goniophotometer. The method may be chosen depending upon what other measurements quantities (color, intensity distribution) need to be measured., the size of SSL products, and other requirements.
The integrating sphere is suited for total luminous flux and color measurements of integrated LED lamps and relative small size LED luminaries. Advantage of using integrating sphere is that it does not requires the “ Dark Room”., and also it is less time consuming.
The Goniophotometer provides measurements of Luminous Intensity Distribution as well as total luminous flux. It can take measurements of larger size luminaries as well as small size luminaries. It has to be installed in Dark Room. Measurements in goniophotometer are time consuming.
| Integrating Sphere | Goniophotometer | |
| Conditions | No Dark room | Dark Room |
| Size of SSL | Small Size luminaries | Large size as well as small size Luminaries |
| Measurements | Total Luminous Flux | Light Intensity Distribution , Total Luminous Flux |
| Duration of Test | Fast Measurements | Time consuming as compared to Sphere photometer. |

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:
- Total luminous flux
- Electrical powers
- Luminous Intensity distribution
- Efficacy (lm/watt)
- 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:
- LM-79 requires complete luminaire testing
- Traditionally, photometric evaluation of lighting products is based on separate tests for lamps and luminaires (Relative)
- For SSL products, LED lamps typically cannot be separated from their luminaire because of heat effects (Absolute)
Relative vs. Absolute Photometry:
- 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
- Absolute testing – The actual light distribution and intensity of the luminaire of interest is measured directly from the complete luminaire.
