WP934EB/2GD 3mm绿光灯珠产品概述

WP934EB/2GD是Kingbright推出的一款3mm直径双列直插(DIP)封装绿光灯珠,针对工业级小体积指示需求设计,兼具低功耗、宽温适应性与显色一致性,是电子设备状态指示、小型显示模块的常用核心元件。

一、产品核心身份与定位

该灯珠属于Kingbright常规小功率LED产品线,主打紧凑空间适配与高可靠性指示,区别于高亮度大功率LED,聚焦“清晰可见、低功耗、长寿命”的指示类场景,无需额外散热设计即可稳定工作,适配从消费电子到工业控制的多领域需求。

二、关键电气与光学参数解析

(1)电气性能

  • 正向压降(Vf):典型值2.2V,符合绿光LED的常规压降范围,限流电阻设计简单(若以5V电源供电,串联220Ω电阻即可满足额定电流);
  • 正向电流(If):额定工作电流20mA,最大功耗62.5mW,长期工作无过热风险,适合电池供电设备(如小型遥控器);
  • 反向电压:行业常规≥5V,可有效避免反向电流对灯珠的损坏。

(2)光学性能

  • 发光颜色:翠绿色(主波长568nm,峰值波长565nm),属于人眼敏感的绿光波段,强光环境下仍易辨识;
  • 发光强度:22.5mcd,满足近距离指示需求(如设备面板、按键提示),不会因过亮刺眼;
  • 发光角度:50°,中等发散角设计,兼顾“单点清晰”与“周边可视”,适合窄边框指示区域;
  • 透镜特性:雾状绿色透镜,柔化光线同时保持绿光纯度,避免透镜反光干扰视觉体验。

三、封装与物理特性

  • 封装类型:DIP-4-2.54mm(双列直插,引脚间距2.54mm),兼容常规PCB焊接工艺,支持手工或自动插件;
  • 物理尺寸:3mm直径,高度符合DIP封装标准,可嵌入厚度≤5mm的PCB,适配智能手表、小型传感器等紧凑设备;
  • 引脚材质:铜镀锡工艺,焊接可靠性高,抗氧化能力强,长期使用无引脚虚焊风险。

四、应用场景适配性

  1. 工业控制领域:PLC模块、传感器节点、电机控制器的状态指示(-40℃~+85℃宽温可适配车间极端温度);
  2. 消费电子:电子秤、遥控器、小型家电(如加湿器)的功能指示灯(雾状透镜降低夜间刺眼);
  3. 通讯设备:路由器、交换机、光模块的链路状态指示(22.5mcd亮度清晰可见,不干扰其他指示灯);
  4. 医疗设备:小型诊断仪器(如血糖测试仪)的辅助状态提示(低功耗适合电池供电设备)。

五、环境与可靠性表现

  • 工作温度范围:-40℃至+85℃,覆盖北方冬季户外设备、南方高温车间等极端场景;
  • 寿命表现:Kingbright工业级LED典型寿命≥50000小时,若工作电流控制在18mA以内,寿命可进一步延长;
  • 抗干扰性:雾状透镜减少环境光反射,批量生产时光学与电气参数偏差小(Vf偏差≤0.2V,发光强度偏差≤10%),无“忽亮忽暗”问题。

六、品牌与品质背书

Kingbright作为台湾老牌LED厂商,WP934EB/2GD符合RoHS 2.0、REACH等环保标准,批量供应时参数一致性高,无需额外筛选成本,是电子设备量产的可靠选择。

该灯珠以“小体积、高可靠、易适配”为核心优势,覆盖多领域指示需求,是替代传统白炽灯、荧光灯的理想选择。

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
