コンプライアンス概要

この概要は現在英語のみで提供しています。

適用範囲

This standard applies to road traffic signal lamps used on roads in China, including motor vehicle, non-motor vehicle, pedestrian crossing, and lane signal lamps. It covers various light sources such as incandescent, low-voltage halogen, and LED. It is mandatory for all manufacturers and suppliers of traffic signal equipment entering the Chinese market. The standard does not apply to non-road or private traffic signaling devices.

技術要求

The standard specifies comprehensive optical performance requirements for both patterned and non-patterned signal lamps. This includes minimum and maximum luminous intensity on the geometric axis, as well as specific light distribution patterns to ensure visibility from various angles. Manufacturers must ensure that optical performance does not degrade significantly after one year of use. It defines strict chromaticity performance limits for red, yellow, and green light signals, ensuring color recognition under various conditions, including the presence of phantom light caused by environmental reflections. Additionally, the standard sets requirements for power consumption and power factor, with specific limits depending on the light source type and lamp size. The standard also mandates several operational and safety features. These include start/stop response times of less than 100ms, night dimming functionality, and LED failure detection mechanisms that automatically shut down the unit if over 50% of LEDs fail. Signal lamps must also incorporate robust electrical safety features, including specific insulation resistance and dielectric strength limits. Environmental durability is a key focus, requiring lamps to withstand extreme temperatures (-40°C to 80°C), humidity, salt spray, and vibrations. The standard also includes specific requirements for solar-powered signal lamps, covering battery matching, overcharge/discharge protection, and continuous operation performance.

試験方法

The standard outlines rigorous testing procedures, including photometric testing in darkrooms to measure luminous intensity and brightness distribution. It also specifies phantom light testing using simulated CIE A light sources to evaluate reflection interference. Environmental tests such as high/low temperature, damp heat, salt spray, and vibration are conducted according to GB/T 2423 series standards. Additionally, specialized tests for LED failure detection, solar panel matching, and dielectric strength are detailed.

よくある質問

What products are regulated under GB 14887-2011?

GB 14887-2011 regulates road traffic signal lamps used on public roads, including motor vehicle, non-motor vehicle, pedestrian, and lane signal lamps, regardless of whether they use incandescent, halogen, or LED light sources.

Are there any updates from the previous version of GB 14887?

Yes, GB 14887-2011 replaces GB 14887-2003. Key updates include increased brightness and luminous intensity requirements for patterned signal lamps, the addition of LED failure detection functionality, new requirements for solar-powered signal lamps, and extended high/low temperature testing durations.

Does GB 14887-2011 apply to solar-powered traffic signal lamps?

Yes, the standard includes a dedicated section for solar-powered signal lamps, covering requirements for battery matching, overcharge/discharge protection, polarity reverse connection protection, and continuous operation performance.
