WP934MD/LILGD 产品概述

一、产品简述

WP934MD/LILGD 为 Kingbright 品牌的 RED/GREEN 双电平指示 LED(BI‑LEVEL),在同一器件中提供红色与黄绿色两种发光状态,可通过分别驱动对应电极实现双色显示或双色切换。器件采用雾状(磨砂)透镜设计,出光柔和、无明显眩光,适用于面板指示、状态显示及消费类、工业控制等应用场景。封装信息未注明,请以厂方数据手册为准。

二、主要特性

  • 发光颜色:红色、黄绿色(双色二级显示)
  • 透镜颜色:雾状红色透镜、雾状绿色透镜
  • 发光角度:50°(典型)
  • 工作温度范围:-40℃ ~ +85℃
  • 推荐正向电流(典型):2 mA(单色)
  • 品牌:Kingbright

三、电光参数(典型值)

  • 黄绿色(Green/Yellow)
    • 正向压降 Vf:约 2.10 V
    • 峰值波长:≈ 565 nm(名义波长 568 nm)
    • 最大功率耗散:75 mW(器件级/色别请参考数据表)
    • 发光强度:典型 8 mcd
  • 红色(Red)
    • 正向压降 Vf:约 2.25 V
    • 峰值波长:≈ 627 nm(名义波长 617 nm)
    • 最大功率耗散:62.5 mW(器件级/色别请参考数据表)
    • 发光强度:典型 3 mcd

注:上述为典型/名义参数,器件在不同温度、电流条件下会有所偏移,选型时应参考 Kingbright 官方完整规格书与绝对最大额定值。

四、应用场景

  • 仪表面板与状态指示(电源、故障、运行状态)
  • 家用电器和消费电子的功能/状态反馈
  • 工业控制面板与信号指示灯
  • 任何需要双色指示且空间受限的场合

五、使用建议与电路示例

  • 恒流驱动或限流电阻驱动均可。推荐单色工作电流以 2 mA 为基准进行设计,以保证亮度与可靠性平衡。
  • 限流电阻计算公式:R = (Vsup − Vf) / If。示例(If=2 mA):
    • 以 5 V 供电驱动黄绿色:R ≈ (5 − 2.10) / 0.002 ≈ 1.45 kΩ(可选 1.5 kΩ)
    • 以 5 V 供电驱动红色:R ≈ (5 − 2.25) / 0.002 ≈ 1.375 kΩ(可选 1.3 kΩ 或 1.5 kΩ)
  • 若需更高亮度,可短时超额定值驱动,但须遵守绝对最大额定并考虑热耗散与寿命影响。长期使用请避免超过推荐正向电流。

六、装配与可靠性注意事项

  • 由于为双色二级结构,常见引脚配置为双独立电极,请在装配前确认引脚定义(共阴/共阳或独立脚位)。
  • 推荐在回流焊工艺中参考 Kingbright 的温度曲线,避免长时间高温影响发光二极管寿命。
  • 工作环境避免长期高湿、高腐蚀性气氛,存储时防潮防静电。

七、选型与订购建议

  • 封装细节、引脚排列、絕對最大额定值及光学曲线,请以 Kingbright 官方数据表为准;若需样品或批量采购,建议提供 WP934MD/LILGD 的完整料号并向授权经销商确认。
  • 如需替代品或更高亮度/更小角度/不同封装形式,可与供应商沟通匹配要求。

总结:WP934MD/LILGD 为适合面板和指示用途的双色 BI‑LEVEL 指示灯,黄绿色与红色两种发光色彩在低电流下即可实现明显的状态区分,雾状透镜与 50° 的出光角度适合近距离观察与面板装配。选型时请重点确认官方封装与绝对最大额定值以确保可靠使用。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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.

Replenishment inquiry Typical RFQ workflow
