Automotive Light Source Opto-Electronic Testing System

Automotive light color affects not only appearance but also driving safety. Regulations such as UN R48, SAE J578, ADR 92/00, JIS D 5500 impose strict chromaticity requirements on headlights, turn signals, brake lights, reverse lights (white, red, amber). This automotive light source opto-electronic test system, based on the SPM-5000 array spectrometer and integrating sphere, delivers high-precision, high-efficiency light color measurement for compliance and signal clarity. Compliant with GB 4599-2024, GB 5920-2024, UN R48, SAE J578, ADR 92/00, JIS D 5500:1995. Key parameters: relative spectral power distribution, chromaticity coordinates (x,y), CCT, CRI, luminous flux, dominant wavelength, peak wavelength, color purity, SDCM, intensity distribution. 100% LED module testing.

Core Application Scenarios

Why does automotive light color measurement matter for safety?

Automotive light color affects not only appearance but also driving safety. UN R48, SAE J578, ADR 92/00, JIS D 5500 impose strict chromaticity requirements on headlights, turn signals, brake lights, reverse lights (white, red, amber). This system, based on the SPM-5000 array spectrometer, delivers high-precision, high-efficiency measurement for compliance and signal clarity.

What standards does it comply with? How does SPM-5000 meet them?

Compliant with GB 4599-2024, GB 5920-2024, UN R48, SAE J578, ADR 92/00, JIS D 5500. The SPM-5000 array spectrometer with CCD sensor achieves measurement times as low as 10µs. Accurately measures relative SPD, chromaticity, CCT, CRI, flux, SDCM. With integrating sphere, forms a complete automotive light color test system meeting regulatory chromaticity requirements for headlights, turn signals, brake lights, reverse lights.

What are the key parameters for light color measurement?

Key chromaticity parameters: relative spectral power distribution, chromaticity coordinates (x,y) (CIE 1931 position), CCT (white consistency), dominant/peak wavelength (hue), color purity, SDCM (deviation from standard), CRI, luminous flux, intensity distribution (uniformity). SPM-5000 measures all in one pass to determine compliance with UN R48, SAE J578.

What automotive light sources and luminaires is it suitable for?

For opto-electronic testing of headlights, high beam, turn signals, brake lights, reverse lights, position lights and other automotive LED modules. Focus on light color compliance with white, red, amber chromaticity requirements. Based on SPM-5000 and integrating sphere; 100% inspection for incoming, process and finished product testing; ensures compliance and signal clarity.
