WP934EW/GD 产品概述

一、产品简介

WP934EW/GD 是 Kingbright 旗下的一款 3mm 黄色偏绿色(黄绿色)发光二极管,采用雾状绿色透镜(diffused green lens),整体外观为柔和的散光型指示灯。该器件在典型正向电流 10mA 条件下发出色温偏黄绿色的光,峰值波长约 565nm,典型波长 568nm,适用于面板指示、状态显示及视觉提示等场合,兼顾亮度与视觉舒适度。

二、主要特性

  • 发光颜色:黄绿色(yellow-green)
  • 峰值波长:565nm,典型波长:568nm
  • 正向电流(IF):10mA(额定)
  • 正向压降(Vf):2.0V ~ 2.4V
  • 发光强度:25 mcd(在 IF=10mA 时)
  • 发光角度:50°(中等汇聚、适合局部指示)
  • 透镜:雾状绿色,出光柔和且具漫散射效果
  • 工作温度范围:-40℃ ~ +85℃

三、电气与光学参数要点

  • 额定工作点:若以 IF=10mA 为设计参考,器件在常温下的 Vf 典型值约 2.0–2.4V。实际使用时请按具体批次的光电参数(bin)校准驱动电流与电阻。
  • 功率限制:额定电功率约 62.5 mW(请避免长期工作在极限功率下以免影响寿命)。
  • 光学输出:25 mcd 属于中低亮度指示级别,搭配雾状透镜可获得均匀、无眩光的视觉效果,适合近距离观察的面板与指示灯应用。
  • 发光角度 50° 意味着照射较集中,适用于需要方向性提示的位置,但非用于大范围照明。

四、机械与封装建议

  • 该器件为 3mm 常规外形,适配常见 3mm LED 安装孔径与引脚布局。实际 PCB 钻孔尺寸、引脚长度与弯折方式请参照 Kingbright 官方封装图纸以保证安装一致性。
  • 由于透镜为雾状塑料,避免长期暴露在强溶剂或腐蚀性化学剂环境中,以免影响外观与透光性。

五、典型应用场景

  • 工业控制面板与信号指示
  • 家电状态指示(如洗衣机、微波炉面板指示)
  • 仪器仪表前面板灯
  • 低功耗指示类便携设备

六、使用与驱动建议

  • 串联限流电阻:以 5V 电源为例,建议电阻 R = (Vs - Vf) / IF。按 Vf 取中值 2.2V、IF=10mA,R ≈ 280Ω,常选 270Ω 或 300Ω;电阻功率仅约 0.03W,采用 1/8W(0.125W)或 1/4W 电阻均足够。对于更高电压同理计算并选择合适电阻。
  • 驱动与散热:尽量不超过数据表额定 IF 以延长寿命。高温环境下应适当降额驱动(降低 IF),并保证周边环境良好散热。
  • ESD 与焊接:LED 对静电、热敏感,建议在组装与测试过程中采取 ESD 防护。关于回流焊温度曲线与手工焊接参数,请按 Kingbright 官方规范执行,避免直接引用未确认的焊接参数。

七、储存与可靠性

  • 推荐在干燥、避光、常温环境中存放,避免高温高湿。长期高温或强紫外照射会加速透镜老化与光输出下降。
  • 在设计产品寿命与可靠性时,考虑到 LED 的光衰随时间与温度增加,建议在关键应用中预留亮度裕量或采用降额使用策略。

八、采购与替代

  • 品牌:Kingbright,可通过官方授权分销商或正规电子元器件供应链采购,以确保批次一致性与售后支持。
  • 若需更高亮度或不同视角、封装形式,可在 Kingbright 或其他主流厂商中查找相近波长与尺寸的替代型号,并对比光学 bin、Vf 范围与机械封装图纸后选型。

总结:WP934EW/GD 是一款面向面板与指示用途的 3mm 黄绿色漫散光 LED,具备适中的亮度与良好的视觉友好性。在电路设计时应按 Vf 与 IF 数据合理限流、注意降额以保证长期稳定性,并参考厂方 datasheet 完整实现封装与焊接工艺。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
