LED RoHS & Lead-Free Packaging: Export Compliance Checklist & Report Guide

发布于: 2026-08-12 09:40

"你们的灯珠过 RoHS 吗?有报告吗?"——做出口订单的客户,这是我们每天必答的问题。RoHS 合规本身不难,难的是分清真合规和纸面合规:同样一张 RoHS 报告,有的是针对该型号该批次的实测,有的是拿别人家报告 PS 的。欧盟市场监管抽查一旦命中不合规,整柜货召回,损失按百万计。

这篇把 LED 灯珠环保合规的要点、报告核查方法和无铅封装的概念讲清楚。

一、RoHS 到底限制什么

RoHS(欧盟电子电气设备有害物质限制指令)限制 10 类物质,和灯珠直接相关的主要是:

物质 限值 在灯珠里的风险点
铅(Pb) 1000 ppm 焊料、支架镀层、玻璃封装
汞(Hg) 1000 ppm LED 天然不含,区别于荧光灯
镉(Cd) 100 ppm 某些荧光粉、镀层
六价铬(Cr⁶⁺) 1000 ppm 金属表面处理
PBB/PBDE 1000 ppm 阻燃剂(胶体、PCB 相关)
4 项邻苯(DEHP/BBP/DBP/DIBP) 1000 ppm 胶体增塑剂

"无铅封装" 是 RoHS 合规的子集,特指封装过程中不使用含铅焊料和含铅材料——LED 灯珠本身不焊接(出厂时),无铅主要指支架镀层、固晶材料和后续可焊性镀层满足无铅要求,使灯珠能耐受无铅回流焊的高温(260℃)。

二、无铅封装为什么和"耐高温"绑定

有铅焊料回流焊峰值约 235℃,无铅焊料(SAC305)峰值 250-260℃。灯珠要通过无铅回流焊不变色、不裂胶、不死灯,对胶体和支架的耐温性要求高一档:

  • 胶体:耐高温环氧树脂或硅胶,260℃/10s 三次无黄变
  • 支架镀层:纯银或银合金镀层,不含铅基底
  • 固晶材料:无铅固晶胶

所以"无铅封装"不仅是环保合规,也是灯珠耐高温能力的侧面证明。规格书上标注"无铅回流焊 260℃ 兼容"的灯珠,基本可以放心上无铅产线。

三、RoHS 报告怎么查真伪:四步核查

1. 看报告主体:检测报告应由有资质的第三方实验室出具(SGS、CTI、TÜV、Intertek 等),实验室官网可查报告编号。

2. 看样品描述:报告上的样品名称、型号、照片要与采购的灯珠一致。警惕"一份报告管全厂所有型号"——正规做法是按材料族系分组检测,组内材料和工艺相同的型号共享报告是合理的,跨材料体系共用就可疑。

3. 看检测方法:应是 XRF 筛查 + 化学法确认(IEC 62321 系列标准),只有 XRF 初筛的报告说服力不足。

4. 看日期:材料或工艺变更后应重新检测。报告日期超过 2-3 年且厂家无材料变更声明的,建议要求更新。

直接的做法:要求厂家提供报告编号,自己上实验室官网验证。5 分钟的事,能过滤掉九成纸面合规。

四、出口订单的完整合规包

做欧美出口的整机厂,建议向灯珠供应商要齐这套文件:

  • RoHS 10 项检测报告(第三方)
  • REACH SVHC 高关注物质声明(欧盟)
  • 无卤素声明(Halogen Free,部分客户要求)
  • 材料声明表(MDS)/ 冲突矿产声明(北美客户常要)
  • 对应批次的出货检验报告(COC)

弘呈光电全系列灯珠通过 RoHS 10 项第三方检测,报告编号可官网查验,REACH、无卤声明随货提供,出口订单按客户模板出具批次 COC。

五、FAQ

Q:RoHS 报告需要每批次都做吗?

不需要逐批全项检测,但要求厂家做批次抽检并保留记录;材料/工艺变更必须重新检测。采购合同里可以约定"每年更新一次报告"。

Q:国内销售的产品也要 RoHS 吗?

中国有对应的《电器电子产品有害物质限制使用管理办法》(中国 RoHS),强制标识要求。国内销售的正规灯珠同样应满足限值要求。

Q:无铅灯珠能用有铅工艺焊接吗?

完全可以,向下兼容。反过来(有铅灯珠上无铅产线)才是问题——耐温不够会裂胶死灯。

Q:RoHS 和光衰、可靠性有关系吗?

没有直接关系,但有间接相关性:能做稳定无铅高温工艺的厂家,材料和设备水平通常也在线,可靠性好是大概率事件。

六、小结

环保合规三件事:RoHS 10 项报告(编号可验真)、无铅封装(耐 260℃ 回流焊)、出口要齐 REACH+无卤声明+批次 COC。核查报告四步走,纸面合规无所遁形。

Frequently Asked Questions (FAQ)

1. Can I get free LED samples from Hongcheng Optoelectronics?

Yes. Dongguan Hongcheng Optoelectronics Co., Ltd. supports sample testing — you can verify electro-optical parameters, dimensions and soldering compatibility before placing bulk orders. To request samples, call +86 139 2571 4318 (WeChat same number) or email sales@led-hc.com with the model and quantity you need.

2. What is the minimum order quantity (MOQ)?

The MOQ for DIP (through-hole) LEDs is 1K (1,000 pcs); for SMD LEDs the MOQ is 3-5K, shipped in tape-and-reel packaging. The MOQ for customized models (special wavelength, brightness or voltage binning) is confirmed per custom solution. Please contact sales for an accurate quotation and MOQ for your model.

3. What are the lead times for samples and mass production?

Sample lead time is typically 3-4 working days; in-stock samples are usually shipped within 2 working days. Mass production lead time is typically 10-15 working days, confirmed according to order quantity and production schedule — please contact sales for an accurate lead time.
