적용 범위

This standard applies to the design, manufacture, and acceptance of road illumination devices and systems for M and N category motor vehicles. It covers passing beams (low beams), driving beams (high beams), front fog lamps, and cornering lamps. It is mandatory for all automotive lighting manufacturers targeting the Chinese market. The standard does not apply to cornering lamps when specific exclusions are noted in the text (e.g., certain material and stability tests).

기술 요구 사항

The standard specifies comprehensive requirements for light sources, mandating that replaceable filament, gas-discharge, and LED sources comply with UN R37, UN R99, and UN R128. It explicitly permits the use of LED modules and laser light source modules for headlamps, provided they meet strict safety criteria like IEC 60825-1 and IEC 62471-7. Manufacturers must ensure light sources are designed to prevent misoperation and incorrect positioning. For photometric performance, the standard defines precise test points and areas for passing beams, driving beams, front fog lamps, and cornering lamps. It includes specific parameters for basic, adaptive, and bending modes. Notably, it introduces requirements for driver assistance projection functions, allowing the projection of symbols or patterns (e.g., lane-keeping warnings) within defined angular limits, provided they do not cause glare. The standard also outlines stability requirements for photometric performance under clean, soiled, and heated conditions. It sets strict limits on the vertical position shift of the cut-off line due to thermal effects. Additionally, for devices using plastic lenses, it mandates rigorous material testing for temperature resistance, weathering, chemical resistance, and mechanical wear. Compliance with these material tests is critical for ensuring long-term durability.

시험 방법

The standard outlines various testing procedures, primarily conducted in a dark room at 23°C ± 5°C. Key tests include photometric measurements using a goniophotometer at a standard distance of 25m, cut-off line aiming and quality verification (evaluating sharpness and linearity), and stability testing under clean and soiled conditions. It also details material tests for plastic lenses, including weathering, chemical exposure, and mechanical abrasion, as well as specific methods for measuring UV and red light components of LED and laser modules.

자주 묻는 질문

What products are regulated under GB 4599-2024?

GB 4599-2024 applies to road illumination devices and systems, including passing beams (low beams), driving beams (high beams), front fog lamps, and cornering lamps used on M and N category vehicles. It is mandatory for manufacturers producing these lighting devices for the Chinese automotive market.

Are there any significant updates from the previous version of GB 4599?

The 2024 edition is a major consolidation replacing six previous standards (e.g., GB 4599-2007, GB 25991-2010). Key updates include the addition of driver assistance projection functions, requirements for adaptive driving beams, new passing beam test points and areas, and the introduction of laser light source modules for headlamps. Manufacturers must transition to the new requirements by the specified implementation dates.

How does GB 4599-2024 differ from international standards like UN ECE regulations?

The standard aligns closely with international regulations by extensively referencing UN R37, UN R99, UN R128, and R.E.5 for light source specifications. However, it incorporates specific Chinese national requirements, such as unique test point grids for photometric performance and distinct administrative implementation timelines for domestic type approval.

The summary above provides a high-level overview of GB 4599-2024. To ensure complete compliance for your products entering the Chinese market, a precise and professional translation of the full technical specifications is essential.
