1、 LM-79 test
IES LM-79 is the optical and electrical measurement method of solid-state lighting products.
Note: Solid state lighting products are defined in the standard as products that use LEDs (including organic or inorganic LEDs) as radiation light sources and emit light for general lighting.
LM-79 test range
Solid state lighting products based on LED technology, including control circuit and heat dissipation, can operate only with AC mains power or DC constant voltage power supply.
It is not applicable to solid-state lighting products that require external control circuits or heat dissipation devices, such as LED chips, LED packaging products, and LED modules.
LM-79 certification test items:
1. Photometric test items
Total luminous flux
Photoefficiency
Light intensity distribution
Chromatic coordinate
Relevant color temperature (CCT)
Color rendering index (CRI)
2. Electrical test items
AC/DC input effective current
Effective voltage of AC/DC input
Voltage input frequency (AC)
Power factor PF (AC)
2、 LM-80 test
The LM-80 report is a lumen maintenance rate test report of LED devices (LED Package, Array, Module) issued by the laboratory according to the standard requirements and claimed to be tested according to the IES LM-80 test method.
LM-80 test items:
Lumen maintenance rate:
(1) Integral ball test (0H initial value, 1000H, 2000H...... 5000H, 6000H, 7000H...... 9000H, 10000H......)
(2) Aging test (6000H, 9000H, 10000H...)
3、 LM-82 test
LM-82 is used to test the relationship between the electrical and photometric characteristics of LED Light Engines and integrated LED lights and temperature under working conditions.
LM-82 test items:
Input power
input voltage
Input current
Luminous flux
Luminous efficiency
CIE color coordinate
Correlated color temperature |
