Optical test parameters and standards of Automobile Headlights

With the rapid development of the automobile industry and the improvement of driving speed, it is very necessary to establish various standards and regulations to regulate various parameters of automobiles to ensure the quality of automobiles and people’s increasingly high user experience and safety requirements. Since automobile headlights are very important to ensure driving safety, the standards of automobile headlights occupies a very important position in automobile standards.

At present, the standards applicable to automotive headlight products include ECE R112, SAE J1383, FMVSS108, GB 4599-2007, GB21259-2007, GB25991-2010, etc. These standards are applicable to automobile headlights with different light sources, but they also made uniform regulations for the entire lamp technical requirements, such as general requirements, color, luminous intensity distribution and test methods, and stability of luminous intensity distribution, etc. The following are the parameters the standards request to test:

1. Luminous intensity distribution (This is the most important technical parameter in the standards of Vehicle lighting products)
2. Illuminance stability
3. Chromaticity Coordinates, Color Rendering Index
4. Voltage, Power, luminous flux

LISUN recommend below test equipment which can test these parameters and fully meet above standards:

1. LPCE-2 High Precision Spectroradiometer Integrating Sphere System
LPCE-2 Integrating Sphere Spectroradiometer LED Testing System is for single LEDs and LED lighting products light measurement. LED’s quality should be tested by checking its photometric, colorimetric and electrical parameters. This system can test Voltage, Power, luminous flux, Chromaticity Coordinates, Color Rendering Index and so on. Fully meet CIE127-1997, IES LM-79-08 and part of IES LM-80-08.

High Precision Spectroradiometer Integrating Sphere System LPCE 2-(LMS 9000)

2. LSG-1950 Goniophotometer for Automotive and Signal Lamps
LSG-1950 is a CIE A-α goiophotometer. Mainly measure the lamps and lanterns of the traffic industry, such as traffic signal lamps, buses, trains, ships and aerospace equipment lamps. The photometer head keeps static and it faces to the sample under test while the sample is rotating around both horizontal axis and vertical axis. So the luminous intensity and illuminance of the lamp or luminaires can be tested. Please click here to learn more about this system: LSG-1950 Goniophotometer for Automotive and Signal Lamps
